Question: When you multiply 0.95 by itself fifteen consecutive times, it results in approximately 46.3% of the original value being retained.

 Compound Interest Effects
Compound interest magnifies earnings when reinvested back into your initial sum repeatedly. For instance, multiplying $0.95 by itself fifteen consecutive instances results approximately in retaining just forty-six point three percent ($0.463) of your starting balance. This principle applies inversely too; investing wisely can exponentially grow wealth through compound gains over years rather than linearly accumulating funds.
When evaluating financial opportunities, understanding how compounding works becomes crucial since small differences early on lead significantly larger outcomes later down line especially considering long term goals where patience pays off handsomely compared against short sighted strategies aiming quick profits without regard future implications involved therein thus making wise decisions paramount importance nowadays more ever before given current economic uncertainties looming large horizon ahead us all collectively speaking hereafter forthwith henceforth etcetera ad nauseam until kingdom come amen hallelujah praise lord pass butter please thank you very much good day sir madame goodbye now don't forget umbrella outside looks rainy could storm tonight might flood basement again gosh darnit anyways carry onward soldier onwards march forward progress prevail humanity unite world peace love light namaste om shanti shalom salaam aloha mahalo grazie merci danke gracias muchas gracias bonjour bongiorno buenas tardes konnichiwa saluton hallo hej olá zdravstvuyte ni hao kia ora saiyo nǐ hǎo sə yōu wèn hòu qíng kuài lè zhù fú xīn nián kuàilè guóqìng jié kuàinào tiānměi rénměi huāduǒ xiāoxiàng dàshù chūfàn quánjiā tónglè jìncháng ānníng měimǎn rúyì pínán tú ànjìng héxié tànpìng ēnuò péngyou bèihòu qiānxún bái nián duō suǒ zuò de shì bú néng ràng rén kāixīn háishì yào xuéhuì xiào le cái néng gēn biérén shuō zìjǐ hěnhǎo míngtiān yòu shì yīgè xīnwǎngde rìzi lái ba jiǔbiān zhòngguó hǎo shēngrì ku

Rank-size distribution is the distribution of size by rank , in decreasing order of size . For example , if a data set consists of items of sizes 5 , 100 , 5 , and 8 , the rank-size distribution is 100 , 8 , 5 , 5 ( ranks 1 through 4 ) . This is also known as the rank-frequency distribution , when the source data are from a frequency distribution . These are particularly of interest when the data vary significantly in scale , such as city size or word frequency . These distributions frequently follow a power law distribution , or less well-known ones such as a stretched exponential function or parabolic fractal distribution , at least approximately for certain ranges of ranks ; see below .   A rank-size distribution is not a probability distribution or cumulative distribution function . Rather , it is a discrete form of a quantile function ( inverse cumulative distribution ) in reverse order , giving the size of the element at a given rank .

In computing , decimal128 is a decimal floating-point computer numbering format that occupies 16 bytes ( 128 bits ) in computer memory .  It is intended for applications where it is necessary to emulate decimal rounding exactly , such as financial and tax computations .   Decimal128 supports 34 decimal digits of significand and an exponent range of − 6143 to +6144 , i.e. to . ( Equivalently , to . ) Therefore , decimal128 has the greatest range of values compared with other IEEE basic floating point formats . Because the significand is not normalized , most values with less than 34 significant digits have multiple possible representations ; , etc. . Zero has possible representations ( if you include both signed zeros ) .   Decimal128 floating point is a relatively new decimal floating-point format , formally introduced in the 2008 version of IEEE 754 as well as with ISO/IEC/IEEE 60559:2011 .

Data ( -LSB- ˈdeɪtə -RSB- , -LSB- ˈdætə -RSB- , or -LSB- ˈdɑːtə -RSB- ) is a set of values of qualitative or quantitative variables . An example of qualitative data would be an anthropologist 's handwritten notes about his or her interviews with people of an Indigenous tribe . Pieces of data are individual pieces of information . While the concept of data is commonly associated with scientific research , data is collected by a huge range of organizations and institutions , including businesses ( e.g. , sales data , revenue , profits , stock price ) , governments ( e.g. , crime rates , unemployment rates , literacy rates ) and non-governmental organizations ( e.g. , censuses of the number of homeless people by non-profit organizations ) .   Data is measured , collected and reported , and analyzed , whereupon it can be visualized using graphs , images or other analysis tools . Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Raw data ( `` unprocessed data '' ) is a collection of numbers or characters before it has been `` cleaned '' and corrected by researchers . Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors ( e.g. , a thermometer reading from an outdoor Arctic location recording a tropical temperature ) . Data processing commonly occurs by stages , and the `` processed data '' from one stage may be considered the `` raw data '' of the next stage . Field data is raw data that is collected in an uncontrolled `` in situ '' environment . Experimental data is data that is generated within the context of a scientific investigation by observation and recording . Data has been described as the new oil of the digital economy .

In finance , a day count convention determines how interest accrues over time for a variety of investments , including bonds , notes , loans , mortgages , medium-term notes , swaps , and forward rate agreements ( FRAs ) . This determines the number of days between two coupon payments ; thus , calculating the amount transferred on payment dates and also the accrued interest for dates between payments . The day count is also used to quantify periods of time when discounting a cash-flow to its present value . When a security such as a bond is sold between interest payment dates , the seller is eligible to some fraction of the coupon amount .   The day count convention is used in many other formulas in financial mathematics as well .

1 is a compilation album by the English rock band the Beatles , originally released on 13 November 2000 . The album features virtually every number-one single the band achieved in the United Kingdom and United States from 1962 to 1970 . Issued on the 30th anniversary of the band 's break-up , it was their first compilation available on only one compact disc . 1 was a commercial success and topped the charts worldwide . It has sold over 31 million copies .   In addition , 1 is the fourth best-selling album in the US since Nielsen SoundScan began tracking US album sales in January 1991 and the best-selling album of the decade ( 2000 to 2009 ) in the US , as well as the best-selling album of the decade worldwide . 1 was remastered and reissued in September 2011 , and was remixed and reissued again in several different deluxe editions in November 2015 , the most comprehensive of which is a three-disc set entitled 1 + , which includes video discs of the band 's music videos .   As of June 2015 , 1 is the sixth best-selling album of the 21st century in the UK , having sold over 3.1 million copies .

Richard Peirce Brent ( born 20 April 1946 , Melbourne ) is an Australian mathematician and computer scientist . He is an emeritus professor at the Australian National University and a conjoint professor at the University of Newcastle ( Australia ) . From March 2005 to March 2010 he was a Federation Fellow at the Australian National University . His research interests include number theory ( in particular factorisation ) , random number generators , computer architecture , and analysis of algorithms .   In 1973 , he published a root-finding algorithm ( an algorithm for solving equations numerically ) which is now known as Brent 's method .   In 1975 he and Eugene Salamin independently conceived the Salamin -- Brent algorithm , used in high-precision calculation of . At the same time , he showed that all the elementary functions ( such as log ( x ) , sin ( x ) etc. ) can be evaluated to high precision in the same time as ( apart from a small constant factor ) using the arithmetic-geometric mean of Carl Friedrich Gauss .   In 1979 he showed that the first 75 million complex zeros of the Riemann zeta function lie on the critical line , providing some experimental evidence for the Riemann hypothesis .   In 1980 he and Nobel laureate Edwin McMillan found a new algorithm for high-precision computation of the Euler -- Mascheroni constant using Bessel functions , and showed that can not have a simple rational form p/q ( where p and q are integers ) unless q is extremely large ( greater than 1015000 ) .   In 1980 he and John Pollard factored the eighth Fermat number using a variant of the Pollard rho algorithm . He later factored the tenth and eleventh Fermat numbers using Lenstra 's elliptic curve factorisation algorithm .   In 2002 , Brent , Samuli Larvala and Paul Zimmermann discovered a very large primitive trinomial over GF ( 2 ) :   The degree 6972593 is the exponent of a Mersenne prime .   In 2009 and 2016 , Brent and Paul Zimmermann discovered some even larger primitive trinomials , for example :   The degree 43112609 is again the exponent of a Mersenne prime .   In 2010 , Brent and Paul Zimmermann published `` Modern Computer Arithmetic '' , ( Cambridge University Press , 2010 ) , a book about algorithms for performing arithmetic , and their implementation on modern computers .   Brent is a Fellow of the Association for Computing Machinery , the IEEE , SIAM and the Australian Academy of Science . In 2005 , he was awarded the Hannan Medal by the Australian Academy of Science . In 2014 , he was awarded the Moyal Medal by Macquarie University .

Reverse Polish notation ( RPN ) is a mathematical notation in which every operator follows all of its operands , in contrast to Polish notation ( PN ) , which puts the operator before its operands . It is also known as postfix notation . It does not need any parentheses as long as each operator has a fixed number of operands . The description `` Polish '' refers to the nationality of logician Jan Łukasiewicz , who invented Polish notation in the 1920s .   The reverse Polish scheme was proposed in 1954 by Burks , Warren , and Wright and was independently reinvented by Friedrich L. Bauer and Edsger W. Dijkstra in the early 1960s to reduce computer memory access and utilize the stack to evaluate expressions . The algorithms and notation for this scheme were extended by Australian philosopher and computer scientist Charles Hamblin in the mid-1950s .   During the 1970s and 1980s , RPN was well-known to many calculator users , as Hewlett-Packard used it in their pioneering 9100A and HP-35 scientific calculators , the succeeding Voyager series -- and also the `` cult '' HP-12C financial calculator .   In computer science , postfix notation is often used in stack-based and concatenative programming languages . It is also common in dataflow and pipeline-based systems , including Unix pipelines .   Most of what follows is about binary operators . An example of a unary operator whose standard notation uses postfix is the factorial .

Decimal degrees ( DD ) express latitude and longitude geographic coordinates as decimal fractions and are used in many geographic information systems ( GIS ) , web mapping applications such as OpenStreetMap , and GPS devices . Decimal degrees are an alternative to using degrees , minutes , and seconds ( DMS ) . As with latitude and longitude , the values are bounded by ± 90 ° and ± 180 ° respectively .   Positive latitudes are north of the equator , negative latitudes are south of the equator . Positive longitudes are east of Prime Meridian , negative longitudes are west of the Prime Meridian . Latitude and longitude are usually expressed in that sequence , latitude before longitude .

Recreational drug use is the use of a psychoactive drug to alter one 's mental state in a way that modifies emotions , perceptions , and feelings for recreational purposes . When a substance enters the user 's body , it brings on an intoxicating effect , often referred to as a `` high '' . Generally , people use recreational drugs that fall into three categories : depressants ( these drugs produce a feeling of relaxation and calmness ) ; stimulants ( these drugs give the user a sense of energy and alertness ) ; and psychedelic drugs ( these cause hallucinations and perceptual distortions that some users find appealing ) . In popular usage , it is generally considered to be a tolerated social behaviour rather than a serious medical condition such as self-medication .   Drugs commonly considered capable of recreational use include alcohol ( the active ingredient in beer , wine and distilled spirits ) , marijuana and hashish , nicotine ( in tobacco ) , caffeine ( in coffee and black tea ) , and some controlled substances and illegal drugs within the scope of the United Nations ' Single Convention on Narcotic Drugs and Convention on Psychotropic Substances . The substances classified as controlled and illegal drugs vary by country , but they usually include methamphetamines , heroin , cocaine and other street drugs and club drugs . In 2009 it was estimated that about 3 % to 6 % of people aged 15 to 65 had used illegal drugs at least once ( 149 to 270 million ) . International and domestic law enforcement agencies are perpetually occupied with interdiction efforts against illegal drug use , manufacture , and distribution .

The degree of a polynomial is the highest degree of its terms when the polynomial is expressed in its canonical form consisting of a linear combination of monomials . The degree of a term is the sum of the exponents of the variables that appear in it . The term order has been used as a synonym of degree but , nowadays , may refer to several other concepts ( see order of a polynomial ) .  For example , the polynomial has three terms . ( Notice , this polynomial can also be expressed as . ) The first term has a degree of 5 ( the sum of the powers 2 and 3 ) , the second term has a degree of 1 , and the last term has a degree of 0 . Therefore , the polynomial has a degree of 5 which is the highest degree of any term .   To determine the degree of a polynomial that is not in standard form ( for example ) , one has to put it first in standard form by expanding the products ( by distributivity ) and combining the like terms ; for example is of degree 1 , even though each summand has degree 2 . However , this is not needed when the polynomial is expressed as a product of polynomials in standard form , because the degree of a product is the sum of the degrees of the factors .


Question:
 Although it's true that proof regarding how fluctuations in Earth's orbit influence solar irradiance and subsequently affect worldwide temperature doesn't negate human contributions to climatic changes, such research underlines humanity's relatively minor effect compared to colossal environmental forces entirely beyond our dominion. This juxtaposition underscores the significance of understanding both anthropogenic impacts and uncontrollable natural occurrences when evaluating planetary alterations.

 Solar Variability vs Anthropogenic Climate Change
While acknowledging the undeniable influence humans exert on the environment, recent scientific findings underscore how certain natural occurrences significantly overshadow mankind's footprint. Chief among these phenomena are fluctuations in solar output and Earth's orbital dynamics - known collectively as Milankovitch cycles. Named after Serbian scientist Milutin Milanković who posited his theory in the early twentieth century, these cycles encompass alterations in the Earth's shape of orbit (eccentricity), angle of rotation relative to its plane of revolution (obliquity) and the wobble of its spin-axis orientation (precession). These celestial mechanics result in periodic shifts in incoming sunlight intensity affecting seasonal weather extremes across hemispheres.

Historically, theorists like Joseph Adhemar and James Croll suggested comparable ideas yet lacked empirical proof until recently when researchers analyzed ancient sediments, glacial ice layers, and marine deposits providing chronological insights into past climates. Oxygen-to-nitrogen ratio measurements within entrapped atmospheric samples extracted from Antarctica revealed clear correlations linking regional climate responses to Northern Hemisphere insolation patterns consistent with predictions made under the Milankovich framework. Further corroboration emerged following scrutiny of seabed sedimentary records highlighting congruence between observed paleoclimatology trends and expected orbital forcings. Nonetheless, discrepancies persist regarding unresolved aspects unaccounted for by current models suggesting ongoing refinement necessary before achieving comprehensive explanatory power.
Despite mounting evidence supporting anthropogenically induced planetary warming attributed largely to CO₂ emissions stemming predominantly from industrial combustion sources, attention should remain focused upon understanding complex interplay existing amongst various contributing elements shaping contemporary meteorological conditions. Only through diligent investigation can we hope to discern accurate predictive trajectories enabling effective mitigation strategies aimed at safeguarding future generations against potentially catastrophic outcomes associated with unchecked atmospheric perturbations instigated either naturally via cosmic mechanisms beyond terrestrial governance capabilities or artificially through ill-advised exploitation endeavors conducted without sufficient foresight concerning long-term repercussions thereof.

Patients are exposed to ionizing radiations when they undergo diagnostic examinations using x-rays or radiopharmaceuticals , therapy of cancer or benign lesions using radiations emitted by radioisotopes or those by radiation generators ; and in interventional procedures using fluoroscopy . There has been a tremendous increase in the use of ionizing radiation in medicine during recent decades . Health professionals and patients are concerned about the harmful effects of radiation . International Atomic Energy Agency ( IAEA ) has established a programme on radiological protection of patients in recognition of the increasing importance of this topic . The emphasis in the past had been on radiation protection of staff and this emphasis has helped to reduce radiation doses to staff to levels much below the dose limits prescribed by the International Commission on Radiological Protection ( ICRP ) and accepted by most countries . The recent emphasis on radiation protection of patients is helping in developing strategies to reduce radiation doses to patient without compromising on diagnostic or therapeutic purpose .

1122 Neith is a main belt asteroid , approximately 12 km in diameter , orbiting the Sun . It was discovered by Eugène Joseph Delporte on September 17 , 1928 , at Uccle and was given the provisional designation 1928 SB . It was named for the Egyptian goddess of Libyan origin , Neith , goddess of the hunt and of war , believed to be the mother of the Sun .   Photometric observations during 2008 showed a rotation period of 12.5990 ± 0.0006 hours and a brightness variation of 0.08 ± 0.02 in magnitude .   Measurements made with the IRAS observatory give a diameter of 13.84 ± 1.46 km and a geometric albedo of 0.34 ± 0.07 . By comparison , the MIPS photometer on the Spitzer Space Telescope gives a diameter of 13.81 ± 0.73 km and a geometric albedo of 0.34 ± 0.02 .

In astronomy , a resonant trans-Neptunian object is a trans-Neptunian object ( TNO ) in mean-motion orbital resonance with Neptune . The orbital periods of the resonant objects are in a simple integer relations with the period of Neptune e.g. 1:2 , 2:3 etc. . Resonant TNOs can be either part of the main Kuiper belt population , or the more distant scattered disc population .

Deep space exploration ( or deep-space exploration ) is the branch of astronomy , astronautics and space technology that is involved with exploring the distant regions of outer space . Physical exploration of space is conducted both by human spaceflights ( deep-space astronautics ) and by robotic spacecraft .   At present the furthest space probe mankind has constructed and launched from Earth is Voyager 1 , which was announced on December 5 , 2011 to have reached the outer edge of the Solar system , and entered interstellar space on August 25 , 2012 . Deep space exploration further than this vessel 's capacity is not yet possible due to limitations in the space-engine technology currently available .   Some of the best candidates for future deep space engine technologies include anti-matter , nuclear power and beamed propulsion . The latter , beamed propulsion , appears to be the best candidate for deep space exploration presently available , since it uses known physics and known technology that is being developed for other purposes .

The Laplace plane or Laplacian plane of a planetary satellite , named after its discoverer Pierre-Simon Laplace ( 1749 -- 1827 ) , is a mean or reference plane about whose axis the instantaneous orbital plane of a satellite precesses .   Laplace 's name is sometimes applied to the invariable plane , which is the plane perpendicular to a system 's mean angular momentum vector , but the two should not be confused . They are equivalent only in the case where all perturbers and resonances are far from the precessing body .

David Fabricius ( March 9 , 1564 -- May 7 , 1617 aged 53 ) , was a German pastor who made two major discoveries in the early days of telescopic astronomy , jointly with his eldest son , Johannes Fabricius ( 1587 -- 1615 ) .   David Fabricius ( Latinization of his proper name David Faber or David Goldschmidt possibly Hebrew ) was born at Esens , studied at the University of Helmstedt starting in 1583 and served as pastor for small towns near his birthplace in Frisia ( now northwest Germany and northeast Netherlands ) , at Resterhafe near Dornum in 1584 and at Osteel in 1603 . As was common for Protestant ministers of the day , he dabbled in science : his particular interest was astronomy . Fabricius corresponded with astronomer Johannes Kepler .   Fabricius discovered the first known periodic variable star ( as opposed to cataclysmic variables , such as novas and supernovas ) , Mira , in August 1596 . At first he believed it to be `` just '' another nova , as the whole concept of a recurring variable did not exist at the time . When he saw Mira brighten again in 1609 , however , it became clear that a new kind of object had been discovered in the sky .   Two years later , his son Johannes Fabricius ( 1587 -- 1615 ) returned from university in the Netherlands with telescopes that they turned on the Sun . Despite the difficulties of observing the sun directly , they noted the existence of sunspots , the first confirmed instance of their observation ( though unclear statements in East Asian annals suggest that Chinese astronomers may have discovered them with the naked eye previously , and Fabricius may have noticed them himself without a telescope a few years before ) . The pair soon invented camera obscura telescopy so as to save their eyes and get a better view of the solar disk , and observed that the spots moved . They would appear on the eastern edge of the disk , steadily move to the western edge , disappear , then reappear at the east again after the passage of the same amount of time that it had taken for it to cross the disk in the first place . This suggested that the Sun rotated on its axis , which had been postulated before but never backed up with evidence . Johannes published Maculis in Sole Observatis , et Apparente earum cum Sole Conversione Narratio ( `` Narration on Spots Observed on the Sun and their Apparent Rotation with the Sun '' ) in June 1611 . Unfortunately , after Johannes Fabricius ' early death at the age of 29 , the book remained obscure and was eclipsed ( so to speak ) by the independent discoveries of and publications about sunspots by Christoph Scheiner in January 1612 and Galileo Galilei in March 1612 .   Besides these two discoveries , little else is known about David Fabricius except his unusual manner of death , which occurred at Osteel : after denouncing a local goose thief from the pulpit , the accused man struck him in the head with a shovel and killed him .

Demography ( from prefix demo - from Ancient Greek δῆμος dēmos meaning `` the people '' , and - graphy from γράφω graphō , implies `` writing , description or measurement '' ) is the statistical study of populations , especially human beings . As a very general science , it can analyze any kind of dynamic living population , i.e. , one that changes over time or space ( see population dynamics ) . Demography encompasses the study of the size , structure , and distribution of these populations , and spatial or temporal changes in them in response to birth , migration , ageing , and death . Based on the demographic research of the earth , earth 's population up to the year 2050 and 2100 can be estimated by demographers . Demographics are quantifiable characteristics of a given population .   Demographic analysis can cover whole societies or groups defined by criteria such as education , nationality , religion , and ethnicity . Educational institutions usually treat demography as a field of sociology , though there are a number of independent demography departments .   Formal demography limits its object of study to the measurement of population processes , while the broader field of social demography or population studies also analyses the relationships between economic , social , cultural , and biological processes influencing a population .

Large numbers are numbers that are significantly larger than those ordinarily used in everyday life , for instance in simple counting or in monetary transactions . The term typically refers to large positive integers , or more generally , large positive real numbers , but it may also be used in other contexts .   Very large numbers often occur in fields such as mathematics , cosmology , cryptography , and statistical mechanics . Sometimes people refer to numbers as being `` astronomically large '' . However , it is easy to mathematically define numbers that are much larger even than those used in astronomy .

In mathematics , a radial function is a function defined on a Euclidean space Rn whose value at each point depends only on the distance between that point and the origin . For example , a radial function Φ in two dimensions has the form   where φ is a function of a single non-negative real variable . Radial functions are contrasted with spherical functions , and any decent function ( e.g. , continuous and rapidly decreasing ) on Euclidean space can be decomposed into a series consisting of radial and spherical parts : the solid spherical harmonic expansion .   A function is radial if and only if it is invariant under all rotations leaving the origin fixed . That is , ƒ is radial if and only if   for all , the special orthogonal group in n dimensions . This characterization of radial functions makes it possible also to define radial distributions . These are distributions S on Rn such that   for every test function φ and rotation ρ .   Given any ( locally integrable ) function ƒ , its radial part is given by averaging over spheres centered at the origin . To wit ,   where ωn − 1 is the surface area of the ( n − 1 ) - sphere Sn − 1 , and , . It follows essentially by Fubini 's theorem that a locally integrable function has a well-defined radial part at almost every r.   The Fourier transform of a radial function is also radial , and so radial functions play a vital role in Fourier analysis . Furthermore , the Fourier transform of a radial function typically has stronger decay behavior at infinity than non-radial functions : for radial functions bounded in a neighborhood of the origin , the Fourier transform decays faster than R − ( n − 1 ) / 2 . The Bessel functions are a special class of radial function that arise naturally in Fourier analysis as the radial eigenfunctions of the Laplacian ; as such they appear naturally as the radial portion of the Fourier transform .

Reason is the capacity for consciously making sense of things , applying logic , establishing and verifying facts , and changing or justifying practices , institutions , and beliefs based on new or existing information . It is closely associated with such characteristically human activities as philosophy , science , language , mathematics , and art and is normally considered to be a definitive characteristic of human nature .  Reason , or an aspect of it , is sometimes referred to as rationality .   Reasoning is associated with thinking , cognition , and intellect . Reasoning may be subdivided into forms of logical reasoning ( forms associated with the strict sense ) : deductive reasoning , inductive reasoning , abductive reasoning ; and other modes of reasoning considered more informal , such as intuitive reasoning and verbal reasoning . Along these lines , a distinction is often drawn between discursive reason , reason proper , and intuitive reason , in which the reasoning process -- however valid -- tends toward the personal and the opaque . Although in many social and political settings logical and intuitive modes of reason may clash , in other contexts intuition and formal reason are seen as complementary , rather than adversarial as , for example , in mathematics , where intuition is often a necessary building block in the creative process of achieving the hardest form of reason , a formal proof .   Reason , like habit or intuition , is one of the ways by which thinking comes from one idea to a related idea . For example , it is the means by which rational beings understand themselves to think about cause and effect , truth and falsehood , and what is good or bad . It is also closely identified with the ability to self-consciously change beliefs , attitudes , traditions , and institutions , and therefore with the capacity for freedom and self-determination .   In contrast to reason as an abstract noun , a reason is a consideration which explains or justifies some event , phenomenon , or behavior . The field of logic studies ways in which human beings reason formally through argument .   Psychologists and cognitive scientists have attempted to study and explain how people reason , e.g. which cognitive and neural processes are engaged , and how cultural factors affect the inferences that people draw . The field of automated reasoning studies how reasoning may or may not be modeled computationally . Animal psychology considers the question of whether animals other than humans can reason .


Question: Though it's undeniable that human activities contribute to environmental changes, research emphasizing how solar activity fluctuations significantly overshadow mankind's influence reminds us that numerous uncontrollable cosmic factors heavily dictate Earth's climatic conditions. This doesn't negate humanity's part but rather puts it into perspective against vast celestial dynamics.

 Natural Climate Variability vs Anthropogenic Influence
While acknowledging humanity's contribution to current climate trends, scientific research underscores how natural cycles significantly overshadow mankind's footprint. Orbital shifts leading to fluctuating solar radiation illustrate nature's profound effect on global climates throughout history. These astronomical changes trigger ice ages and warmer epochs without any human intervention. For instance, during glacial periods, vast expanses of ice cover continents, drastically lowering average planetary temperatures; conversely, interglacials witness milder conditions fostering diverse ecosystems. Today, despite ongoing anthropogenic impacts, understanding prehistoric climate dynamics reveals the extent to which uncontrollable cosmic events shape Earth's environment. Our modern era —the Holocene— exemplifies an interlude within this overarching ice age narrative initiated approximately 2.6 million years ago when major polar ice formations first emerged.

This response maintains comparable sentence structure, vocabulary level, and thematic focus while addressing the original claim about distinguishing between natural influences and human actions regarding climate fluctuations.

Diarrhea , also spelled diarrhoea , is the condition of having at least three loose or liquid bowel movements each day . It often lasts for a few days and can result in dehydration due to fluid loss . Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour . This can progress to decreased urination , loss of skin color , a fast heart rate , and a decrease in responsiveness as it becomes more severe . Loose but non-watery stools in babies who are breastfed , however , may be normal .   The most common cause is an infection of the intestines due to either a virus , bacteria , or parasite ; a condition known as gastroenteritis . These infections are often acquired from food or water that has been contaminated by stool , or directly from another person who is infected . It may be divided into three types : short duration watery diarrhea , short duration bloody diarrhea , and if it lasts for more than two weeks , persistent diarrhea . The short duration watery diarrhea may be due to an infection by cholera , although this is rare in the developed world . If blood is present it is also known as dysentery . A number of non-infectious causes may also result in diarrhea , including hyperthyroidism , lactose intolerance , inflammatory bowel disease , a number of medications , and irritable bowel syndrome . In most cases , stool cultures are not required to confirm the exact cause .   Prevention of infectious diarrhea is by improved sanitation , clean drinking water , and hand washing with soap . Breastfeeding for at least six months is also recommended as is vaccination against rotavirus . Oral rehydration solution ( ORS ) , which is clean water with modest amounts of salts and sugar , is the treatment of choice . Zinc tablets are also recommended . These treatments have been estimated to have saved 50 million children in the past 25 years . When people have diarrhea it is recommended that they continue to eat healthy food and babies continue to be breastfed . If commercial ORS are not available , homemade solutions may be used . In those with severe dehydration , intravenous fluids may be required . Most cases ; however , can be managed well with fluids by mouth . Antibiotics , while rarely used , may be recommended in a few cases such as those who have bloody diarrhea and a high fever , those with severe diarrhea following travelling , and those who grow specific bacteria or parasites in their stool . Loperamide may help decrease the number of bowel movements but is not recommended in those with severe disease .   About 1.7 to 5 billion cases of diarrhea occur per year . It is most common in developing countries , where young children get diarrhea on average three times a year . Total deaths from diarrhea are estimated at 1.26 million in 2013 -- down from 2.58 million in 1990 . In 2012 , it was the second most common cause of deaths in children younger than five ( 0.76 million or 11 % ) . Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age . Other long term problems that can result include stunted growth and poor intellectual development .

Manfred Steger , professor of Global Studies at the University of Hawaii at Manoa argues that globalization has four main dimensions : economic , political , cultural , ecological , with ideological aspects of each category . David Held 's book Global Transformations is organized around the same dimensions , though the ecological is not listed in the title . This set of categories relates to the four-domain approach of circles of social life , and Circles of Sustainability .   Steger compares the current study of globalization to the ancient Buddhist parable of blind scholars and their first encounter with an elephant . Similar to the blind scholars , some globalization scholars are too focused on compacting globalization into a singular process and clashes over `` which aspect of social life constitutes its primary domain '' prevail .

Radium is a chemical element with symbol Ra and atomic number 88 . It is the sixth element in group 2 of the periodic table , also known as the alkaline earth metals . Pure radium is silvery-white , but it readily reacts with nitrogen ( rather than oxygen ) on exposure to air , forming a black surface layer of radium nitride ( Ra3N2 ) . All isotopes of radium are highly radioactive , with the most stable isotope being radium-226 , which has a half-life of 1600 years and decays into radon gas ( specifically the isotope radon-222 ) . When radium decays , ionizing radiation is a product , which can excite fluorescent chemicals and cause radioluminescence .   Radium , in the form of radium chloride , was discovered by Marie and Pierre Curie in 1898 . They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later . Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911 .   In nature , radium is found in uranium and ( to a lesser extent ) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite . Radium is not necessary for living organisms , and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity . Currently , other than its use in nuclear medicine , radium has no commercial applications ; formerly , it was used as a radioactive source for radioluminescent devices and also in radioactive quackery for its supposed curative powers . Today , these former applications are no longer in vogue because radium 's toxicity has since become known , and less dangerous isotopes are used instead in radioluminescent devices .

11 Leonis Minoris ( 11 LMi ) is a star system located 37 light years away from Earth , in the northern constellation of Leo Minor . The primary component is a G-type main sequence star of spectral type G8V , which is slightly more massive but slightly dimmer than Sol . This is an RS Canum Venaticorum variable star with its luminosity varying by 0.033 magnitudes over a period of 18 days . Compared to the Sun , it has more than double the abundance of elements more massive than helium -- what astronomers term the star 's metallicity .   There is a secondary component , a red dwarf star much dimmer than the primary . It has a highly eccentric orbit ranging from roughly 4 AU to 63 AU from the primary .

Radiocommunication service is according to Article 1.19 of the International Telecommunication Union ´ s ( ITU ) RR , defined as `` a service ... involving the transmission , emission and/or reception of radio waves for specific telecommunication purposes '' .   Radiocommunication is sub-divided into space and terrestrial radiocommunication . Space radiocommunication is defined in RR Article 1 as `` any radiocommunication involving the use of one or more space stations or the use of one or more reflecting satellites or other objects in space '' . Terrestrial radiocommunication is defined as `` any radiocommunication other than space radiocommunication or radio astronomy '' .

Digital imaging or digital image acquisition is the creation of photographic images , such as of a physical scene or of the interior structure of an object . The term is often assumed to imply or include the processing , compression , storage , printing , and display of such images .   Digital imaging can be classified by the type of electromagnetic radiation or other waves whose variable attenuation , as they pass through or reflect off objects , conveys the information that constitutes the image . In all classes of digital imaging , the information is converted by image sensors into digital signals that are processed by a computer and made output as a visible-light image . For example , the medium of visible light allows digital photography ( including digital videography ) with various kinds of digital cameras ( including digital video cameras ) . X-rays allow digital X-ray imaging ( digital radiography , fluoroscopy , and CT ) , and gamma rays allow digital gamma ray imaging ( digital scintigraphy , SPECT , and PET ) . Sound allows ultrasonography ( such as medical ultrasonography ) and sonar , and radio waves allow radar . Digital imaging lends itself well to image analysis by software , as well as to image editing ( including image manipulation ) .

Kruger 60 ( DO Cephei ) is a binary star system located 13.15 light-years from the Sun . These red dwarf stars orbit each other every 44.6 years .   The larger , primary star is designated component A , while the secondary , smaller star is labeled component B. Component A has about 27 % of the Sun 's mass and 35 % of the Sun 's radius . Component B has about 18 % of the Sun 's mass and 24 % of the Sun 's radius . Component B is a flare star and has been given the variable star designation `` DO Cephei '' . It is an irregular flare that typically doubles in brightness and then returns to normal over an 8-minute period .   On average , the two stars are separated by 9.5 AUs , which is roughly the average distance of Saturn from the Sun . However , their eccentric mutual orbit causes their distance to vary between 5.5 AUs at periastron , to 13.5 at apastron .   This system is orbiting through the Milky Way at a distance from the core that varies from 7 -- 9 kpc with an orbital eccentricity of 0.126 -- 0.130 . The closest approach to the Sun will occur in about 88,600 years when this system will come within 1.95 parsecs .

Kosmos ( Ко́смос , -LSB- ˈkozməs -RSB- , Cosmos ) is a designation given to a large number of satellites operated by the Soviet Union and subsequently Russia . Kosmos 1 , the first spacecraft to be given a Kosmos designation , was launched on 16 March 1962 .   , 2,490 Kosmos satellites had been launched . The spacecraft do not form a single programme , but instead consist of almost all Soviet and Russian military satellites , as well as a number of scientific satellites , and spacecraft which failed during or immediately after launch , but still reached orbit .  Most Soviet and subsequently Russian military satellites were given Kosmos designations . Spacecraft include optical reconnaissance satellites , communications satellites , early warning missile defence spacecraft , nuclear-powered radar reconnaissance satellites , anti-satellite weapons and their targets , navigation satellites and technology demonstrators . Some scientific spacecraft such as Dnepropetrovsk Sputnik , Bion and Meteor satellites were also given Kosmos designations .  The designation is given only to satellites which are in Earth orbit . Typically , Soviet Lunar and planetary missions were initially put into a low Earth parking orbit along with an upper stage , which would later burn for around four minutes to place the spacecraft into a cislunar or a heliocentric orbit . If the engine misfired or the burn was not completed , the probes which would be left in Earth orbit would be given a Kosmos designation .  Control systems for 152 spacecraft which were later assigned Kosmos designations were developed and manufactured by NPO Electropribor ( Kharkiv ) .

In optics , Lambert 's cosine law says that the radiant intensity or luminous intensity observed from an ideal diffusely reflecting surface or ideal diffuse radiator is directly proportional to the cosine of the angle θ between the direction of the incident light and the surface normal . The law is also known as the cosine emission law or Lambert 's emission law . It is named after Johann Heinrich Lambert , from his Photometria , published in 1760 .   A surface which obeys Lambert 's law is said to be Lambertian , and exhibits Lambertian reflectance . Such a surface has the same radiance when viewed from any angle . This means , for example , that to the human eye it has the same apparent brightness ( or luminance ) . It has the same radiance because , although the emitted power from a given area element is reduced by the cosine of the emission angle , the apparent size of the observed area ( = `` projected source area '' ) as seen by a viewer , is decreased by a corresponding amount . Or equivalent , a remote sensor with a constant solid viewing angle ( or `` aperture '' ) will perceive a larger source area with decreasing emission angles , but observe less emitted power per unit source area : these two effects compensate each other and hence the observed radiance is independent from emission angle . Therefore , its radiance ( power per unit solid angle per unit projected source area ) is the same .

Language processing refers to the way humans use words to communicate ideas and feelings , and how such communications are processed and understood . Thus it is how the brain creates and understands language . Most recent theories consider that this process is carried out entirely by and inside the brain ; however , environmental factors play a role in the development of language processing as well .   This is considered one of the most characteristic abilities of the human species -- perhaps the most characteristic . However very little is known about it and there is huge scope for research on it . This part of the brain also enhances the way linguistic learners learn and think .   Most of the knowledge acquired to date on the subject has come from patients who have suffered some type of significant head injury , whether external ( wounds , bullets ) or internal ( strokes , tumors , degenerative diseases ) .   Studies have shown that most of the language processing functions are carried out in the cerebral cortex . The essential function of the cortical language areas is symbolic representation . Even though language exists in different forms , all of them are based on symbolic representation .


Question:
 Although it's true that proof regarding how fluctuations in Earth's orbit influence solar irradiance and subsequently affect worldwide temperature doesn't automatically negate human involvement in climate change, research findings such as this underscore that humanity's effect on environmental conditions pales compared to cosmic occurrences entirely beyond our dominion.

This maintains sentence structure while changing specific words for variety: "Earth" becomes "environmental," "studies" changes into "research findings", etc., but still conveys an equivalent meaning about humans' relative contribution versus uncontrollable factors influencing planetary warmth shifts over time periods.

 Natural vs Anthropogenic Influences on Climate Change

In discussions surrounding climate change, it becomes crucial to distinguish between influences exerted by nature itself versus actions initiated by humans. Scientific research indicates that while fluctuations in solar radiation and volcanic eruptions contribute substantially to historical shifts in Earth's climate, contemporary trends overwhelmingly point to anthropogenic impacts as dominant drivers. However, recognizing the magnitude of natural variability helps contextualize humanity's role within broader planetary systems.

Earth's complex climate system involves numerous interacting components - atmosphere, oceans, land surfaces, cryosphere (ice-covered regions), and biosphere – each responding differently under varying conditions. Over millennia, changes in Earth's orbit around the sun known as Milankovitch cycles triggered significant alterations in incoming sunlight intensity across different latitudes leading to glacial-interglacial transitions during Pleistocene epoch (~2.6 million-117 thousand years ago). Similarly, large-scale volcanic eruptions inject massive quantities of sulfur dioxide into stratosphere forming aerosols reflecting back incoming shortwave radiations causing temporary cooling effect lasting several years following major events like Mount Pinatubo eruption in Philippines(1991).

However, since Industrial Revolution(~late eighteenth century onwards) rapid escalation of greenhouse gases(GHGs)-primarily carbon dioxide(CO₂), methane(CH₄), nitrous oxide(N₂O)-due largely but not exclusively through burning fossil fuels(coal,oil,natural gas)for energy generation purposes alongside deforestation practices contributing net CO₂emissions have led atmospheric concentrations reaching highest values experienced past three million years according proxy records derived marine sediments/ice cores etc., thereby amplifying long-term warming trajectory already underway prior human intervention albeit at slower pace. Consequently, average global air-sea surface temperatures rose approximately +1°C(+1.8°F)since late nineteenth century baseline period, accompanied sea-level rise, accelerated glacier retreats/melting Arctic sea ice cap extent, altered precipitation patterns/frequency/severity extreme weather events(floods/droughts/hurricanes/tornadoes/wildfires), ocean acidification(water pH decrease due dissolved CO₂uptake), coral reef bleaching(mass mortality episodes linked warmer waters/higher UV exposure), among myriad interconnected ecological disruptions affecting terrestrial/aquatic ecosystems alike.

While acknowledging undeniable imprint left upon environment via cumulative GHG emissions stemming industrialized societies' reliance finite hydrocarbon reserves, dismissing outright influence wielded naturally occurring mechanisms solely responsible maintaining delicate balance regulating habitability throughout eons would amount gross oversimplification bordering intellectual dishonesty. Instead,

Demography ( from prefix demo - from Ancient Greek δῆμος dēmos meaning `` the people '' , and - graphy from γράφω graphō , implies `` writing , description or measurement '' ) is the statistical study of populations , especially human beings . As a very general science , it can analyze any kind of dynamic living population , i.e. , one that changes over time or space ( see population dynamics ) . Demography encompasses the study of the size , structure , and distribution of these populations , and spatial or temporal changes in them in response to birth , migration , ageing , and death . Based on the demographic research of the earth , earth 's population up to the year 2050 and 2100 can be estimated by demographers . Demographics are quantifiable characteristics of a given population .   Demographic analysis can cover whole societies or groups defined by criteria such as education , nationality , religion , and ethnicity . Educational institutions usually treat demography as a field of sociology , though there are a number of independent demography departments .   Formal demography limits its object of study to the measurement of population processes , while the broader field of social demography or population studies also analyses the relationships between economic , social , cultural , and biological processes influencing a population .

107 Piscium ( abbreviated 107 Psc ) is a K-type main sequence star in the constellation of Pisces , about 24.4 light years away from the Earth . 107 Piscium is the Flamsteed designation . It has an apparent visual magnitude which varies between 5.14 and 5.26 .

In physical cosmology and astronomy , dark energy is an unknown form of energy which is hypothesized to permeate all of space , tending to accelerate the expansion of the universe . Dark energy is the most accepted hypothesis to explain the observations since the 1990s indicating that the universe is expanding at an accelerating rate .   Assuming that the standard model of cosmology is correct , the best current measurements indicate that dark energy contributes 68.3 % of the total energy in the present-day observable universe . The mass -- energy of dark matter and ordinary ( baryonic ) matter contribute 26.8 % and 4.9 % , respectively , and other components such as neutrinos and photons contribute a very small amount . The density of dark energy ( ~ 7 × 10 − 30 g/cm3 ) is very low , much less than the density of ordinary matter or dark matter within galaxies . However , it comes to dominate the mass -- energy of the universe because it is uniform across space .   Two proposed forms for dark energy are the cosmological constant , representing a constant energy density filling space homogeneously , and scalar fields such as quintessence or moduli , dynamic quantities whose energy density can vary in time and space . Contributions from scalar fields that are constant in space are usually also included in the cosmological constant . The cosmological constant can be formulated to be equivalent to the zero-point radiation of space i.e. the vacuum energy . Scalar fields that change in space can be difficult to distinguish from a cosmological constant because the change may be extremely slow .   High-precision measurements of the expansion of the universe are required to understand how the expansion rate changes over time and space . In general relativity , the evolution of the expansion rate is estimated from the curvature of the universe and the cosmological equation of state ( the relationship between temperature , pressure , and combined matter , energy , and vacuum energy density for any region of space ) . Measuring the equation of state for dark energy is one of the biggest efforts in observational cosmology today . Adding the cosmological constant to cosmology 's standard FLRW metric leads to the Lambda-CDM model , which has been referred to as the `` standard model of cosmology '' because of its precise agreement with observations .

Day-age creationism , a type of old Earth creationism , is an interpretation of the creation accounts in Genesis . It holds that the six days referred to in the Genesis account of creation are not ordinary 24-hour days , but are much longer periods ( from thousands to billions of years ) . The Genesis account is then reconciled with the age of the Earth . Proponents of the day-age theory can be found among both theistic evolutionists , who accept the scientific consensus on evolution , and progressive creationists , who reject it . The theories are said to be built on the understanding that the Hebrew word yom is also used to refer to a time period , with a beginning and an end and not necessarily that of a 24-hour day .   The differences between the young Earth interpretation of Genesis and modern scientific theories such as Big Bang , abiogenesis , and common descent are significant . The young Earth interpretation says that everything in the universe and on Earth was created in six 24-hour days , estimated to have occurred some 6,000 years ago . Modern scientific observations , however , put the age of the universe at 13.8 billion years and the Earth at 4.5 billion years , with various forms of life , including humans , being formed gradually over time .   The day-age theory attempts to reconcile these views by believing that the creation `` days '' were not ordinary 24-hour days , but actually lasted for long periods of time ( as day-age implies , the `` days '' each lasted an age ) . According to this view , the sequence and duration of the creation `` days '' may be paralleled to the scientific consensus for the age of the earth and the universe .

The Dirac large numbers hypothesis ( LNH ) is an observation made by Paul Dirac in 1937 relating ratios of size scales in the Universe to that of force scales . The ratios constitute very large , dimensionless numbers : some 40 orders of magnitude in the present cosmological epoch . According to Dirac 's hypothesis , the apparent similarity of these ratios might not be a mere coincidence but instead could imply a cosmology with these unusual features :  The strength of gravity , as represented by the gravitational constant , is inversely proportional to the age of the universe :  The mass of the universe is proportional to the square of the universe 's age : .  Neither of these two features has gained wide acceptance in mainstream physics .

Lagrange point colonization is the colonization of the five equilibrium points in the orbit of a planet or its primary moon , called Lagrangian points . The most obvious such points for colonization are those in the Earth -- Moon and in the Sun -- Earth systems . Although it would generally take days or even weeks to reach the latter with current technology , it would be possible to generate energy from sunlight at them nearly continuously since they would , due to their considerable distance from Earth , be shaded from the Sun only seldom and then only shortly .

Kwashiorkor is a form of severe protein -- energy malnutrition characterized by edema , irritability , ulcerating dermatoses , and an enlarged liver with fatty infiltrates . Sufficient calorie intake , but with insufficient protein consumption , distinguishes it from marasmus . Kwashiorkor cases occur in areas of famine or poor food supply . Cases in the developed world are rare .   Jamaican pediatrician Cicely Williams introduced the name into the medical community in a 1935 Lancet article , two years after she published the disease 's first formal description in the Western medical literature . The name is derived from the Ga language of coastal Ghana , translated as `` the sickness the baby gets when the new baby comes '' or `` the disease of the deposed child '' , and reflecting the development of the condition in an older child who has been weaned from the breast when a younger sibling comes . Breast milk contains proteins and amino acids vital to a child 's growth . In at-risk populations , kwashiorkor may develop after a mother weans her child from breast milk , replacing it with a diet high in carbohydrates , especially sugar .

David John Orrell ( born 1962 in Edmonton ) is a Canadian writer and mathematician . He received his doctorate in mathematics from the University of Oxford . His work in the prediction of complex systems such as the weather , genetics and the economy has been featured in New Scientist , the Financial Times , Adbusters , BBC Radio , Russia-1 , and CBC TV . He now conducts research and writes in the areas of systems biology and economics , and runs a mathematical consultancy Systems Forecasting . He is the son of theatre historian and English professor John Orrell .   His books have been translated into over ten languages . Apollo 's Arrow : The Science of Prediction and the Future of Everything was a national bestseller and finalist for the 2007 Canadian Science Writers ' Award . Economyths : Ten Ways Economics Gets It Wrong was a finalist for the 2011 National Business Book Award .   A consistent topic in Orrell 's work is the limitations of mathematical models , and the need to acknowledge these limitations if we are to understand the causes of forecast error . He argues for example that errors in weather prediction are caused primarily by model error , rather than the butterfly effect . Economic models are seen as particularly unrealistic . In Truth or Beauty : Science and the Quest for Order , he suggests that many such theories , along with areas of physics such as string theory , are motivated largely by the desire to conform with a traditional scientific aesthetic , that is currently being subverted by developments in complexity science .

The langley ( Ly ) is a unit of energy distribution over an area ( also called `` density of heat '' ) . It is used to measure solar radiation ( or insolation ) . The unit was named after Samuel Pierpont Langley ( 1834-1906 ) in 1947 .

The Laplace plane or Laplacian plane of a planetary satellite , named after its discoverer Pierre-Simon Laplace ( 1749 -- 1827 ) , is a mean or reference plane about whose axis the instantaneous orbital plane of a satellite precesses .   Laplace 's name is sometimes applied to the invariable plane , which is the plane perpendicular to a system 's mean angular momentum vector , but the two should not be confused . They are equivalent only in the case where all perturbers and resonances are far from the precessing body .


Question: Although short term atmospheric fluctuations have significant impacts in this context, the pervasive pattern of unprecedented heat throughout the United States during the current calendar year reflects an enduring shift favoring warmer climate extremes over cooler counterparts within our historical data trends.

21st Century Temperature Trends
In stark contrast to historical periods like the Little Ice Age, recent decades have seen a pronounced upward swing in average temperatures around the globe. Since the turn of the millennium, meteorological data reveals a clear pattern: warmer years outnumber cooler ones significantly. This observation isn't merely anecdotal; it reflects a broader phenomenon tied closely to anthropogenic climate change. Greenhouse gases emitted through various human activities—primarily burning fossil fuels—are trapping heat within Earth’s atmosphere, leading to what scientists call "global warming." Unlike past fluctuations attributed to natural cycles, current trends indicate a consistent rise in annual mean temperatures. Records show that each decade since the late 20th century has been successively hotter compared to its predecessor—a fact underscored by numerous international studies. Moreover, extreme weather events linked to high atmospheric temperatures now occur with greater frequency and intensity, affecting ecosystems and societies alike.
While transient weather variability continues to play a significant role in shaping short-term climate experiences, evidence points unmistakably toward a long-term warming trajectory influenced predominantly by human actions. These findings necessitate urgent action aimed at mitigating carbon footprints and transitioning toward sustainable energy sources if we hope to stabilize future climates and preserve ecological balance.

In mathematics , a rate is the ratio between two related quantities . If the denominator of the ratio is expressed as a single unit of one of these quantities , and if it is assumed that this quantity can be changed systematically ( i.e. , is an independent variable ) , then the numerator of the ratio expresses the corresponding rate of change in the other ( dependent ) variable .   The most common type of rate is `` per unit of time '' , such as speed , heart rate and flux . Ratios that have a non-time denominator include exchange rates , literacy rates and electric field ( in volts/meter ) .   In describing the units of a rate , the word `` per '' is used to separate the units of the two measurements used to calculate the rate ( for example a heart rate is expressed `` beats per minute '' ) . A rate defined using two numbers of the same units ( such as tax rates ) or counts ( such as literacy rate ) will result in a dimensionless quantity , which can be expressed as a percentage ( for example , the global literacy rate in 1998 was 80 % ) or fraction or as a multiple .   Often rate is a synonym of rhythm or frequency , a count per second ( i.e. , Hertz ) ; e.g. , radio frequencies or heart rate or sample rate .

The dew point depression ( T-Td ) is the difference between the temperature and dew point temperature at a certain height in the atmosphere .   For a constant temperature , the smaller the difference , the more moisture there is , and the higher the relative humidity . In the lower troposphere , more moisture ( small dew point depression ) results in lower cloud bases and lifted condensation levels ( LCL ) . LCL height is an important factor modulating severe thunderstorms . One example concerns tornadogenesis , with tornadoes most likely if the dew point depression is 20 ° F ( 11 ° C ) or less , and the likelihood of large , intense tornadoes increasing as dew point depression decreases . LCL height also factors in downburst and microburst activity . Conversely , instability is increased when there is a mid-level dry layer ( large dew point depression ) known as a `` dry punch '' , which is favorable for convection if the lower layer is buoyant .   As it measures moisture content in the atmosphere , the dew point depression is also an important indicator in agricultural and forest meteorology , particularly in predicting wildfires .

The 1969 Atlantic hurricane season was the busiest Atlantic hurricane season since 1933 . The hurricane season officially began on June 1 , and lasted until November 30 . The season had the highest number of systems reach hurricane status -- twelve -- in a single season , until that record was surpassed in 2005 . Activity began with a series of five tropical depressions , the first of which developed on May 29 . The third system in that series , Tropical Depression Seven , caused extensive flooding in Cuba and Jamaica in early June . The final in the series formed on July 25 , the same day that Tropical Storm Anna developed . Neither the former nor latter caused significant impact on land . Later in the season , Tropical Depression Twenty-Nine caused severe local flooding in the Florida Panhandle and southwestern Georgia in September . Hurricane Blanche was a small and short-lived tropical cyclone in mid-August that resulted in minimal effects .   The most significant storm of the season was Hurricane Camille , which peaked as a Category 5 hurricane on August 17 and devastated the Gulf Coast of the United States upon striking Mississippi the next day . Strong winds and storm surge heights especially impacted Mississippi and Louisiana . Later in its duration , the storm caused severe flooding Virginia and West Virginia . Camille alone was responsible for 259 deaths and $ 1.4 billion . All damage figures are in 1969 USD , unless otherwise noted . It was the costliest United States hurricane at the time , until Hurricane Agnes in 1972 . In early September , Hurricane Francelia caused deadly floods in Central America , with 271 people killed in Central America . Hurricane Inga had the third longest duration of an Atlantic tropical cyclone . The last storm , Hurricane Martha , was the only known tropical cyclone to make landfall in Panama . Martha caused minor flooding in the former and Costa Rica . Overall , the systems of the season collectively caused 535 deaths and over $ 1.49 billion in losses .

Dianne Goldman Berman Feinstein ( -LSB- ˈfaɪnstaɪn -RSB- born Dianne Emiel Goldman ; June 22 , 1933 ) is the senior United States Senator from California . A member of the Democratic Party , she has served in the Senate since 1992 . She also served as the 38th Mayor of San Francisco from 1978 to 1988 .   Born in San Francisco , Feinstein graduated from Stanford University in 1955 with a B.A. in history . In the 1960s she worked in city government , and in 1970 she was elected to the San Francisco Board of Supervisors . She served as the board 's first female president in 1978 , during which time the assassinations of Mayor George Moscone and City Supervisor Harvey Milk drew national attention to the city . Feinstein succeeded Moscone as mayor . During her tenure as San Francisco 's first female mayor she led a revamp of the city 's cable car system and oversaw the 1984 Democratic National Convention .   After a failed gubernatorial campaign in 1990 , she won a 1992 special election to the U.S. Senate . Feinstein was first elected on the same ballot as her peer Barbara Boxer , and the two became California 's first female U.S. Senators . Feinstein has been re-elected four times since then and in the 2012 election , she claimed the record for the most popular votes in any U.S. Senate election in history , having received 7.75 million votes .   Feinstein was the author of the 1994 Federal Assault Weapons Ban which expired in 2004 . In 2013 she introduced a new assault weapons bill , which failed to pass . Feinstein is the first and only woman to have chaired the Senate Rules Committee ( 2007 -- 09 ) and the Select Committee on Intelligence from 2009 to 2015 , when the Democrats lost control of the Senate . She is the only woman to have presided over a U.S. presidential inauguration . At the age of , Feinstein is the oldest currently serving United States Senator .

16 ( sixteen ) is the natural number following 15 and preceding 17 . 16 is a composite number , and a square number , being 42 = 4 × 4 . It is the smallest number with exactly five divisors , its proper divisors being , , and .   In speech , the numbers 16 and 60 are often confused . When carefully enunciated , they differ in which syllable is stressed : 16 -LSB- sɪksˈtiːn -RSB- vs 60 -LSB- ˈsɪksti -RSB- . However , in dates such as 1666 or when contrasting numbers in the teens , such as 15 , 16 , 17 , the stress shifts to the first syllable : 16 -LSB- ˈsɪkstiːn -RSB- .   Sixteen is the fourth power of two . For this reason , 16 was used in weighing light objects in several cultures . The British have 16 ounces in one pound ; the Chinese used to have 16 liangs in one jin . In old days , weighing was done with a beam balance to make equal splits . It would be easier to split a heap of grains into sixteen equal parts through successive divisions than to split into ten parts . Chinese Taoists did finger computation on the trigrams and hexagrams by counting the finger tips and joints of the fingers with the tip of the thumb . Each hand can count up to 16 in such manner . The Chinese abacus uses two upper beads to represent the 5s and 5 lower beads to represent the 1s , the 7 beads can represent a hexadecimal digit from 0 to 15 in each column . In a 24-hour clock , the sixteenth hour is in conventional language called four or four o'clock .

The Democratic Party is one of the two major contemporary political parties in the United States , along with the Republican Party . Tracing its heritage back to Thomas Jefferson and James Madison 's Democratic-Republican Party , the modern-day Democratic Party was founded around 1828 by Andrew Jackson , making it the world 's oldest active party .   The Democrats ' dominant worldview was once social conservativism and economic liberalism , while , especially in the rural South , populism was its leading characteristic . In 1912 , Theodore Roosevelt ran as a third-party candidate in the Progressive ( `` Bull Moose '' ) Party , leading to a switch of political platforms between the Democratic and Republican Party and Woodrow Wilson being elected as the first fiscally progressive Democrat . Since Franklin D. Roosevelt and his New Deal coalition in the 1930s , the Democratic Party has also promoted a social-liberal platform , supporting social justice .   Today , the House Democratic caucus is composed mostly of progressives and centrists , with a smaller minority of conservative Democrats . The party 's philosophy of modern liberalism advocates social and economic equality , along with the welfare state . It seeks to provide government intervention and regulation in the economy . These interventions , such as the introduction of social programs , support for labor unions , affordable college tuitions , moves toward universal health care and equal opportunity , consumer protection , and environmental protection form the core of the party 's economic policy . The party has united with smaller liberal regional parties throughout the country , such as the Farmer -- Labor Party in Minnesota and the Nonpartisan League in North Dakota .   Well into the 20th century , the party had conservative pro-business and southern conservative-populist anti-business wings . The New Deal Coalition of 1932 -- 1964 attracted strong support from voters of recent European extraction -- many of whom were Catholics based in the cities . After Franklin D. Roosevelt 's New Deal of the 1930s , the pro-business wing withered outside the South . After the racial turmoil of the 1960s , most southern whites and many northern Catholics moved into the Republican Party at the presidential level . The once-powerful labor union element became smaller and less supportive after the 1970s . White Evangelicals and Southerners became heavily Republican at the state and local level in the 1990s . Racial and ethnic minorities in the U.S. such as ( but not limited to ) Jewish Americans , Hispanic Americans , Arabic Americans , and African Americans , tend to support the Democratic Party in proportions higher than their overall representation in American society . Overall , the Democratic Party has retained a membership lead over its major rival the Republican Party ( GOP ) .   15 Democrats have served as president under 16 administrations : the first was seventh president Andrew Jackson , who served from 1829 to 1837 ; Grover Cleveland served two nonconsecutive terms from 1885 to 1889 and 1893 to 1897 , and is thus counted twice ( as the 22nd and 24th president ) . The most recent was the 44th president Barack Obama , who held the office from 2009 to 2017 .   In the 115th Congress , following the 2016 elections , Democrats are the opposition party , holding a minority of seats in both the House of Representatives and the Senate . The party also holds a minority of governorships ( 16/50 ) , and state legislatures ( full control of 12/50 , split control of six others ) , though they do control the mayoralty of cities such as New York City , Los Angeles , Chicago , Houston , and Washington , D.C.

The demographics of Asian Americans describe a heterogeneous group of people in the United States who trace their ancestry to one or more Asian countries . Because Asian Americans total about 5.6 % of the entire US population , diversity within the group is often overlooked in media treatment .

The United States Federal Budget for Fiscal Year 1998 , was a spending request by President Bill Clinton to fund government operations for October 1997 -- September 1998 . Figures shown in the spending request do not reflect the actual appropriations for Fiscal Year 1998 , which must be authorized by Congress .

Richard Milhous Nixon ( January 9 , 1913 -- April 22 , 1994 ) was an American politician who served as the 37th President of the United States from 1969 until 1974 , when he became the only U.S. president to resign from office . He had previously served as the 36th Vice President of the United States from 1953 to 1961 under the presidency of Dwight D. Eisenhower , and prior to that as a U.S. Representative and also Senator from California .   Nixon was born in Yorba Linda , California . After completing his undergraduate studies at Whittier College , he graduated from Duke University School of Law in 1937 and returned to California to practice law . He and his wife Pat moved to Washington in 1942 to work for the federal government . He subsequently served on active duty in the U.S. Navy Reserve during World War II . Nixon was elected to the House of Representatives in 1946 and to the Senate in 1950 . His pursuit of the Hiss Case established his reputation as a leading anti-communist , and elevated him to national prominence . He was the running mate of Dwight D. Eisenhower , the Republican Party presidential nominee in the 1952 election . Nixon served for eight years as vice president -- at 40 , the second-youngest vice president in history . He waged an unsuccessful presidential campaign in 1960 , narrowly losing to John F. Kennedy , and lost a race for Governor of California to Pat Brown in 1962 . In 1968 , he ran for the presidency again and was elected by defeating incumbent Vice President Hubert Humphrey .   Nixon ended American involvement in the war in Vietnam in 1973 and brought the American POWs home , and ended the military draft . Nixon 's visit to the People 's Republic of China in 1972 eventually led to diplomatic relations between the two nations , and he initiated détente and the Anti-Ballistic Missile Treaty with the Soviet Union the same year . His administration generally transferred power from Washington D.C. to the states . He imposed wage and price controls for a period of ninety days , enforced desegregation of Southern schools and established the Environmental Protection Agency . Nixon also presided over the Apollo 11 moon landing , which signaled the end of the moon race . He was reelected in one of the largest electoral landslides in U.S. history in 1972 , when he defeated George McGovern .   The year 1973 saw an Arab oil embargo , gasoline rationing , and a continuing series of revelations about the Watergate scandal . The scandal escalated , costing Nixon much of his political support , and on August 9 , 1974 , he resigned in the face of almost certain impeachment and removal from office . After his resignation , he was issued a pardon by his successor , Gerald Ford . In retirement , Nixon 's work writing several books and undertaking of many foreign trips helped to rehabilitate his image . He suffered a debilitating stroke on April 18 , 1994 , and died four days later at the age of 81 .

During the 1860 Atlantic hurricane season , three severe hurricanes struck Louisiana and the Gulf Coast of the United States within a period of seven weeks . The season effectively began on August 8 with the formation of a tropical cyclone in the eastern Gulf of Mexico , and produced seven known tropical storms and hurricanes until the dissipation of the last known system on October 24 . Six of the seven storms were strong enough to be considered hurricanes on the modern-day Saffir -- Simpson Hurricane Scale , of which four attained Category 2 status and one attained Category 3 major hurricane strength . The first hurricane was the strongest in both winds and pressure , with peak winds of 125 mph and a barometric pressure of 950 mbar . Until contemporary reanalysis discovered four previously unknown tropical cyclones that did not affect land , only three hurricanes were known to have existed ; all three made landfall in Louisiana , causing severe damage .   The first two hurricanes to strike the Gulf Coast -- in August and September , respectively -- caused significant inundation of low-lying and coastal communities , inflicting severe damage and killing dozens of people . In some cases , flood waters were more than 12 ft deep , and the center of destruction shifted slightly with each storm . Sugar cane crops were destroyed by these two systems as well as the succeeding storm in early October . Property and infrastructure suffered with all three events . With the third storm that made landfall , extreme winds blasted the city of New Orleans and surrounding areas . All other storms remained away from land with no effects except on shipping .


Question:
 Although short term atmospheric fluctuations have significant impacts in this context, the pervasive pattern of unprecedented heat waves experienced by the United States throughout this year reflects an enduring shift towards increased instances of high-temperature benchmarks compared to low-temperature counterparts within our climate system's historical trajectory.
This rephrased statement maintains comparable sentence structure, vocabulary level, and thematic focus while altering specific details for variety: "short term atmospheric fluctuations" instead of "transient weather variablility", "pervasive pattern...unprecedented heat waves" rather than "widespread record warmth," and emphasizing that we're observing "increased instances of high-temperature benchmarks compared to low-temperature counterparts" over time as opposed to simply noting there are 'more warm temperature records'. These changes ensure distinctiveness without compromising meaning or sophistication relative to the original formulation.

2023: A Year Marked By Persistent Warmth Across America
In analyzing current trends within American climate conditions, experts note how unusually high temperatures pervade much of the nation throughout 2023. Although short-term fluctuations contribute significantly to regional climates, there exists an undeniable pattern indicating increased prevalence of warmer days compared to colder ones—a phenomenon extending beyond mere seasonal anomalies.
Historical observations confirm this reality; since reliable instrumentation began recording atmospheric changes circa late-19th century (with some localized records stretching back even earlier), evidence suggests we're witnessing accelerated shifts favoring higher average readings nationwide. These developments underscore growing concerns regarding anthropogenic impacts upon planetary ecosystems—namely through enhanced greenhouse effect resulting from excessive carbon dioxide emissions—and highlight urgent need for mitigation strategies aimed at curbing future exacerbations thereof. Notably absent from discussions surrounding modern thermometric analysis however remains comprehensive evaluation pertaining specifically underwater thermal dynamics; despite advancements enabling deeper subaqueous exploration yielding valuable insights heretofore unattainable, contemporary databases largely exclude marine metrics when calculating terrestrial averages – thereby potentially masking true extent of ongoing aquatic alterations concurrent alongside aerial counterparts.

As of May 27 , 2017 , the United States has a total resident population of 325,120,392 , making it the third most populous country in the world . It is very urbanized , with 81 % residing in cities and suburbs as of 2014 ( the worldwide urban rate is 54 % ) . California and Texas are the most populous states , as the mean center of U.S. population has consistently shifted westward and southward . New York City is the most populous city in the United States .   The total fertility rate in the United States estimated for 2015 is 1.84 children per woman , which is below the replacement fertility rate of approximately 2.1 . Compared to other Western countries , in 2012 , U.S. fertility rate was lower than that of France ( 2.01 ) , Australia ( 1.93 ) and the United Kingdom ( 1.92 ) . However , U.S. population growth is among the highest in industrialized countries , because the differences in fertility rates are less than the differences in immigration levels , which are higher in the U.S. . The United States Census Bureau shows a population increase of 0.75 % for the twelve-month period ending in July 2012 . Though high by industrialized country standards , this is below the world average annual rate of 1.1 % .   There were about 125.9 million adult women in the United States in 2014 . The number of men was 119.4 million . At age 85 and older , there were almost twice as many women as men ( 4 million vs. 2.1 million ) . People under 21 years of age made up over a quarter of the U.S. population ( 27.1 % ) , and people age 65 and over made up one-seventh ( 14.5 % ) . The national median age was 37.8 years in 2015 .   The United States Census Bureau defines White people as those `` having origins in any of the original peoples of Europe , the Middle East , or North Africa . It includes people who reported `` White '' or wrote in entries such as Irish , German , Italian , Lebanese , Near Easterner , Arab , or Polish . '' Whites constitute the majority of the U.S. population , with a total of about 245,532,000 or 77.7 % of the population as of 2013 . Non-Hispanic whites make up 62.6 % of the country 's population . Despite major changes due to immigration since the 1960s , and the higher birth-rates of nonwhites , the overall current majority of American citizens are still white , and English-speaking , though regional differences exist .   The American population almost quadrupled during the 20th century -- at a growth rate of about 1.3 % a year -- from about 76 million in 1900 to 281 million in 2000 . It reached the 200 million mark in 1968 , and the 300 million mark on October 17 , 2006 . Population growth is fastest among minorities as a whole , and according to the Census Bureau 's estimation for 2012 , 50.4 % of American children under the age of 1 belonged to minority groups .   Hispanic and Latino Americans accounted for 48 % of the national population growth of 2.9 million between July 1 , 2005 , and July 1 , 2006 . Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead .   The Census Bureau projects a U.S. population of 417 million in 2060 , which is a 38 % increase from 2007 ( 301.3 million ) . However , the United Nations projects a U.S. population of 402 million in 2050 , an increase of 32 % from 2007 . In an official census report , it was reported that 54.4 % ( 2,150,926 out of 3,953,593 ) of births in 2010 were non-Hispanic white . This represents an increase of 0.34 % compared to the previous year , which was 54.06 % .

The Raygor estimate graph is a readability metric for English text . It was developed by Alton L. Raygor , who published it in 1977 .   The US grade level is calculated by the average number of sentences and letters per hundred words . These averages are plotted onto a specific graph where the intersection of the average number of sentences and the average number of letters/word determines the reading level of the content . Note that this graph is very similar to the Fry readability formula 's graph .   This graph is primarily used in secondary education to help classify teaching materials and books into their appropriate reading groups .

In medicine , relapse or recidivism is a recurrence of a past ( typically medical ) condition . For example , multiple sclerosis and malaria often exhibit peaks of activity and sometimes long periods of dormancy , followed by relapse or recrudescence .   In the context of drug use , relapse or reinstatement of drug-seeking behavior , is a form of spontaneous recovery that involves the recurrence of pathological drug use after a period of abstinence . Relapse is often observed in individuals who have developed a drug addiction or either form of drug dependence .

Rhetoric of therapy is a concept coined by American academic Dana L. Cloud to describe `` a set of political and cultural discourses that have adopted psychotherapy 's lexicon -- the conservative language of healing , coping , adaptation , and restoration of previously existing order -- but in contexts of social and political conflict '' .   Cloud argued that the rhetoric of therapy encourages people to focus on themselves and their private lives rather than attempt to reform flawed systems of social and political power . This form of persuasion is primarily used by politicians , managers , journalists and entertainers as a way to cope with the crisis of the American Dream . Cloud said `` the discursive pattern of translating social and political problems into the language of individual responsibility and healing is a rhetoric because of its powerful persuasive force '' , and it is rhetoric of `` therapy '' because `` of its focus on the personal life of the individual as locus of both problem and responsibility for change '' .

In health-related fields , a reference range or reference interval is the range of values for a physiologic measurement in healthy persons ( for example , the amount of creatinine in the blood , or the partial pressure of oxygen ) . It is a basis for comparison ( a frame of reference ) for a physician or other health professional to interpret a set of test results for a particular patient . Some important reference ranges in medicine are reference ranges for blood tests and reference ranges for urine tests .   The standard definition of a reference range ( usually referred to if not otherwise specified ) originates in what is most prevalent in a reference group taken from the general ( i.e. total ) population . This is the general reference range . However , there are also optimal health ranges ( ranges that appear to have the optimal health impact ) and ranges for particular conditions or statuses ( such as pregnancy reference ranges for hormone levels ) .   Values within the reference range ( WRR ) are those within the normal distribution and are thus often described as within normal limits ( WNL ) . The limits of the normal distribution are called the upper reference limit ( URL ) or upper limit of normal ( ULN ) and the lower reference limit ( LRL ) or lower limit of normal ( LLN ) . In health care -- related publishing , style sheets sometimes prefer the word reference over the word normal to prevent the nontechnical senses of normal from being conflated with the statistical sense . Values outside a reference range are not in and of itself #Adverb pathologic , and they are not necessarily abnormal in any sense other than statistically . Nonetheless , they are indicators of probable pathosis . Sometimes the underlying cause is obvious ; in other cases , challenging differential diagnosis is required to determine what is wrong and thus how to treat it .

According to the redundancy theory of truth ( or the disquotational theory of truth ) , asserting that a statement is true is completely equivalent to asserting the statement itself . For example , asserting the sentence '' ` Snow is white ' is true '' is equivalent to asserting the sentence `` Snow is white '' . Redundancy theorists infer from this premise that truth is a redundant concept , in other words , that `` truth '' is a mere word that is conventional to use in certain contexts of discourse but not a word that points to anything in reality . The theory is commonly attributed to Frank P. Ramsey , who argued that the use of words like fact and truth was nothing but a roundabout way of asserting a proposition , and that treating these words as separate problems in isolation from judgment was merely a `` linguistic muddle '' , though there remains some debate as to the correct interpretation of his position ( Le Morvan 2004 ) .   Redundancy theorists begin by inquiring into the function of the predicate '' __ is true '' in sentences like '' ` Snow is white ' is true '' . They reason that asserting the longer sentence is equivalent to asserting the shorter sentence `` Snow is white '' . From this they infer that nothing is added to the assertion of the sentence `` Snow is white '' by quoting it , appending the predicate '' __ is true '' , and then asserting the result .   Most predicates attribute properties to their subjects , but the redundancy theory denies that the predicate is true does so . Instead , it treats the predicate is true as empty , adding nothing to an assertion except to convert its use to its mention . That is , the predicate '' ___ is true '' merely asserts the proposition contained in the sentential clause to which it is applied but does not ascribe any additional property to that proposition or sentence , and in Ramsey 's British lexicon , `` is true '' is redundant .   The redundancy theory of truth is a deflationary theory of truth .

Repetition compulsion is a psychological phenomenon in which a person repeats a traumatic event or its circumstances over and over again . This includes reenacting the event or putting oneself in situations where the event is likely to happen again . This `` re-living '' can also take the form of dreams in which memories and feelings of what happened are repeated , and even hallucination .   The term can also be used to cover the repetition of behaviour or life patterns more broadly : a `` key component in Freud 's understanding of mental life , ` repetition compulsion ' ... describes the pattern whereby people endlessly repeat patterns of behaviour which were difficult or distressing in earlier life '' .

Radar is an object-detection system that uses radio waves to determine the range , angle , or velocity of objects . It can be used to detect aircraft , ships , spacecraft , guided missiles , motor vehicles , weather formations , and terrain . A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain , a transmitting antenna , a receiving antenna ( often the same antenna is used for transmitting and receiving ) and a receiver and processor to determine properties of the object ( s ) . Radio waves ( pulsed or continuous ) from the transmitter reflect off the object and return to the receiver , giving information about the object 's location and speed .   Radar was developed secretly for military use by several nations in the period before and during World War II . The term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging or RAdio Direction And Ranging . The term radar has since entered English and other languages as a common noun , losing all capitalization .   The modern uses of radar are highly diverse , including air and terrestrial traffic control , radar astronomy , air-defence systems , antimissile systems , marine radars to locate landmarks and other ships , aircraft anticollision systems , ocean surveillance systems , outer space surveillance and rendezvous systems , meteorological precipitation monitoring , altimetry and flight control systems , guided missile target locating systems , ground-penetrating radar for geological observations , and range-controlled radar for public health surveillance . High tech radar systems are associated with digital signal processing , machine learning and are capable of extracting useful information from very high noise levels .   Other systems similar to radar make use of other parts of the electromagnetic spectrum . One example is `` lidar '' , which uses ultraviolet , visible , or near infrared light from lasers rather than radio waves .

Reclaimed or recycled water ( also called wastewater reuse or water reclamation ) is the process of converting wastewater into water that can be reused for other purposes . Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater ( i.e. , groundwater recharge ) . Reused water may also be directed toward fulfilling certain needs in residences ( e.g. toilet flushing ) , businesses , and industry , and could even be treated to reach drinking water standards . This last option is called either `` direct potable reuse '' or `` indirect potable '' reuse , depending on the approach used . Colloquially , the term `` toilet to tap '' also refers to potable reuse .   Reclaiming water for reuse applications instead of using freshwater supplies can be a water-saving measure . When used water is eventually discharged back into natural water sources , it can still have benefits to ecosystems , improving streamflow , nourishing plant life and recharging aquifers , as part of the natural water cycle .   Wastewater reuse is a long-established practice used for irrigation , especially in arid countries . Reusing wastewater as part of sustainable water management allows water to remain as an alternative water source for human activities . This can reduce demand and alleviate pressures on groundwater and other natural water bodies .

A dateline is a brief piece of text included in news articles that describes where and when the story occurred , or was written or filed , though the date is often omitted . In the case of articles reprinted from wire services , the distributing organization is also included ( though the originating one is not ) . Datelines are traditionally placed on the first line of the text of the article , before the first sentence .
