Question: The assertion that there's solid proof linking greenhouse gas outputs, particularly CO2, directly to climate change phenomena remains unverified.

 Carbon Dioxide Emissions: A Misconstrued Link to Global Warming?
The assertion that there exists no concrete proof linking CO2 emissions to global warming warrants closer examination. To understand the role of greenhouse gases, we should delve into how they function; specifically, certain atmospheric constituents absorb and radiate heat in the form of infrared light, creating what scientists term the greenhouse effect. On Earth, key players here encompass water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Were it not for these gases, Earth’s mean surface temperature might plummet to approximately minus eighteen degrees Celsius instead of its current fifteen-degree warmth.
Since the dawn of the Industrial Age around 1750, anthropogenic actions have escalated atmospheric CO2 levels by forty percent—from pre-industrial era concentrations of roughly two hundred eighty parts per million up until four hundred six parts per million recorded circa early 2017. Despite nature's attempts to mitigate some impacts through absorption mechanisms known as “carbon sinks,” humanity continues pumping vast quantities via burning fossil fuels—coal, crude oils, gaseous hydrocarbons—and engaging practices like deforestation, land degradation, plus livestock farming.
Projections indicate that maintaining contemporary emission trends could lead terrestrial thermometers past historic highs possibly before mid-century mark, posing severe risks onto ecological systems, biological diversity alongside societal welfare across globe. Moreover, recent analyses propose crossing beyond UN Intergovernmental Panel Climate Change outlined danger zone boundary set at +two degree centigrade rise compared baseline period measurements might occur sooner than anticipated—in vicinity late thirties AD timeframe under business-as-usual scenario progression without significant intervention measures undertaken promptly enough scale required reversing course away impending planetary peril precipitated unchecked greenhouse forcing agent accumulation stratosphere troposphere alike.

In economics , the Laffer curve is a representation of the relationship between rates of taxation and the resulting levels of government revenue . Proponents of the Laffer curve claim that it illustrates the concept of taxable income elasticity -- i.e. , taxable income will change in response to changes in the rate of taxation .   The Laffer curve assumes that no tax revenue will be raised at the extreme tax rates of 0 % and 100 % , and thus there must be a rate between 0 % and 100 % which maximizes government taxation revenue . The Laffer curve is typically represented as a graph which starts at 0 % tax with zero revenue , rises to a maximum rate of revenue at an intermediate rate of taxation , and then falls again to zero revenue at a 100 % tax rate . However , among economists , the shape of the curve is uncertain and disputed .   One implication of the Laffer curve is that increasing tax rates beyond a certain point will be counter-productive for raising further tax revenue . A hypothetical Laffer curve for any given economy can only be estimated and such estimates are controversial . The New Palgrave Dictionary of Economics reports that estimates of revenue-maximizing tax rates have varied widely , with a mid-range of around 70 % . Generally , economists have found little support for the claim that tax cuts from current rates increase tax revenues or that most taxes are on the side of the Laffer curve where additional cuts could increase government revenue .   Although economist Arthur Laffer does not claim to have invented the Laffer curve concept , it was popularized in the United States with policymakers following an afternoon meeting with Ford Administration officials Dick Cheney and Donald Rumsfeld in 1974 in which he reportedly sketched the curve on a napkin to illustrate his argument . The term `` Laffer curve '' was coined by Jude Wanniski , who was also present at the meeting . The basic concept was not new ; Laffer himself notes antecedents in the writings of the 14th-century social philosopher Ibn Khaldun .

Residency is a stage of graduate medical training . A resident or house officer is a physician ( one who holds the degree of M.D. , D.O. , or MBBS , MBChB , or BMed ) who practices medicine usually in a hospital or clinic under the direct or indirect supervision of an attending physician . Successful completion of a residency program is a requirement to obtaining an unrestricted license to practice medicine in many jurisdictions . Residency training may be followed by fellowship or `` sub-specialty '' training .   Whereas medical school teaches physicians a broad range of medical knowledge , basic clinical skills , and supervised experience practicing medicine in a variety of fields , medical residency gives in-depth training within a specific branch of medicine . A physician may choose a residency in anesthesiology , ophthalmology , cardiothoracic surgery , dermatology , emergency medicine , family medicine , internal medicine , neurology , neurosurgery , obstetrics and gynecology , otolaryngology , pathology , pediatrics , plastic and reconstructive surgery , psychiatry , physical medicine and rehabilitation , radiology , radiation oncology , oral and maxillofacial surgery , general surgery , urology or other medical specialties .

Reality is the state of things as they actually exist , rather than as they may appear or might be imagined . Reality includes everything that is and has been , whether or not it is observable or comprehensible . A still broader definition includes that which has existed , exists , or will exist .   Philosophers , mathematicians , and other ancient and modern thinkers , such as Aristotle , Plato , Frege , Wittgenstein , and Russell , have made a distinction between thought corresponding to reality , coherent abstractions ( thoughts of things that are imaginable but not real ) , and that which can not even be rationally thought . By contrast existence is often restricted solely to that which has physical existence or has a direct basis in it in the way that thoughts do in the brain .   Reality is often contrasted with what is imaginary , illusory , delusional , ( only ) in the mind , dreams , what is false , what is fictional , or what is abstract . At the same time , what is abstract plays a role both in everyday life and in academic research . For instance , causality , virtue , life , and distributive justice are abstract concepts that can be difficult to define , but they are only rarely equated with pure delusions . Both the existence and reality of abstractions are in dispute : one extreme position regards them as mere words ; another position regards them as higher truths than less abstract concepts . This disagreement is the basis of the philosophical problem of universals .   The truth refers to what is real , while falsity refers to what is not . Fictions are considered not real .

Delegitimisation ( also spelled delegitimation ) is literally the withdrawal of legitimacy , usually from some institution such as a state , cultural practice , etc. which may have acquired it explicitly or implicitly , by statute or accepted practice .   A sociopsychological process which undermines or marginalises an entity by presenting facts and/or value judgments which are construed to withdraw legitimacy is generally observed .   A necessary process for the advancement of human culture , it can in some cases be a self-justifying mechanism , with the ultimate goal of justifying harm of an outgroup .   The concept applies to a wide spectrum of social contexts ranging from disputes about political entities to chronic illnesses .

Dichloromethane ( DCM , or methylene chloride ) is an organic compound with the formula CH2Cl2 . This colorless , volatile liquid with a moderately sweet aroma is widely used as a solvent . Although it is not miscible with water , it is miscible with many organic solvents . One of the most well-known applications of dichloromethane is in the drinking bird heat engine .

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 .

Deductive closure is a property of a set of objects ( usually the objects in question are statements ) . A set of objects , O , is said to exhibit closure or to be closed under a given operation , R , provided that for every object , x , if x is a member of O and x is R-related to any object , y , then y is a member of O . In the context of statements , a deductive closure is the set of all the statements that can be deduced from a given set of statements .   In propositional logic , the set of all true propositions exhibits deductive closure : if set O is the set of true propositions , and operation R is logical consequence , then provided that proposition p is a member of O and p is R-related to q ( i.e. , p q ) , q is also a member of O.

Laser ablation is the process of removing material from a solid ( or occasionally liquid ) surface by irradiating it with a laser beam . At low laser flux , the material is heated by the absorbed laser energy and evaporates or sublimates . At high laser flux , the material is typically converted to a plasma . Usually , laser ablation refers to removing material with a pulsed laser , but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough .

 Carbon Dioxide Emissions: Role in Climate Stability Debate
The debate surrounding whether carbon dioxide emissions contribute significantly to global warming remains contentious despite extensive research. Scientific consensus points to substantial proof linking increased atmospheric CO2 concentrations to planetary heating trends observable across multiple disciplines. Temperature records spanning two centuries corroborate ongoing upward shifts attributed largely to industrial-era pollutants.

In 2013’s Inter-governmental Panel On Climate Change (IPCC) assessment, experts declared “extreme likelihood” humanity’s actions—chiefly through greenhouse gases like CO₂—are chief culprits behind recent warming episodes post World War II era. Models project additional rises ranging approximately +0.3°C –+4.8 °C under varying scenarios depending upon future output volumes; none contradict established bodies’ endorsements globally.

Regional disparities anticipate varied outcomes universally encompassing thermal alterations, surging tides, erratic precipitations alongside desert encroachments within sub-tropical zones. Expected phenomena comprise intensified extremes viz., scorchers, dearths, deluges, blizzards besides glacial retreats, frozen grounds liquefaction plus marine expanses diminution. Consequences critical unto mankind entail agricultural productivity downturns jeopardizing sustenance safety nets coupled with evacuations necessitated via inundations. Given ecological sluggishness complemented enduring airborne contaminant persistence, repercussions shall linger protractedly impacting generations ad infinitum (~tens millennia).

Mitigation strategies targeting curtailment initiatives paired against adaptive measures safeguarding infrastructural robustness vis-a-vis prospective geo-engineering interventions represent plausible countermeasures. Broad adherence enshrined within United Nation Framework Convention Concerning Climatic Alteration (UNFCCC), envisaging avoidance perilous manmade perturbances, mandates drastic reductions aspiring stabilization circa <2.0°C (<1.5°C aspirationally).

Public sentiments regarding escalating temperatures alongside apprehensions pertaining thereto exhibit augmentation lately. Cross-border surveys conducted late last decade revealed approx half populace perceives matter critically demanding urgent attention. Geopolitical variances manifest prominently amongst US-China nationals—foremost contributors annually—to lesser degrees sharing skepticism.

In economics , the demand curve is the graph depicting the relationship between the price of a certain commodity and the amount of it that consumers are willing and able to purchase at any given price . It is a graphic representation of a market demand schedule . The demand curve for all consumers together follows from the demand curve of every individual consumer : the individual demands at each price are added together , assuming independent decision-making .   Demand curves are used to estimate behaviors in competitive markets , and are often combined with supply curves to estimate the equilibrium price ( the price at which sellers together are willing to sell the same amount as buyers together are willing to buy , also known as market clearing price ) and the equilibrium quantity ( the amount of that good or service that will be produced and bought without surplus/excess supply or shortage/excess demand ) of that market . In a monopolistic market , the demand curve facing the monopolist is simply the market demand curve .   Demand curves are usually considered as theoretical structures that are expected to exist in the real world , but real world measurements of actual demand curves are difficult and rare .

The Deutscher Verein des Gas - und Wasserfaches ( DVGW ) is the German association for gas and water with headquarters in Bonn .

Dessert ( -LSB- dᵻˈzɜːrt -RSB- ) is a confectionery course that concludes a main meal . The course usually consists of sweet foods and beverages , such as dessert wine or liqueurs , but may include coffee , cheeses , nuts , or other savory items . In some parts of the world , such as much of central and western Africa , and most parts of China , there is no tradition of a dessert course to conclude a meal .   The term `` dessert '' can apply to many confections , such as cakes , tarts , cookies , biscuits , gelatins , pastries , ice creams , pies , puddings , custards , and sweet soups . Fruit is also commonly found in dessert courses because of its naturally occurring sweetness . Some cultures sweeten foods that are more commonly savory to create desserts .

1,4-Butanediol , colloquially known as BD , is the organic compound with the formula HOCH2CH2CH2CH2OH . It is a colorless viscous liquid . It is one of four stable isomers of butanediol .

In the history of science , Laplace 's demon was the first published articulation of causal or scientific determinism by Pierre-Simon Laplace in 1814 . According to determinism , if someone ( the Demon ) knows the precise location and momentum of every atom in the universe , their past and future values for any given time are entailed ; they can be calculated from the laws of classical mechanics .   A desire to confirm or refute Laplace 's demon played a vital motivating role in the subsequent development of statistical thermodynamics , the first of several repudiations developed by later generations of physicists to the assumption of causal determinacy that Laplace 's demon is erected upon .

Reliability in statistics and psychometrics is the overall consistency of a measure . A measure is said to have a high reliability if it produces similar results under consistent conditions . `` It is the characteristic of a set of test scores that relates to the amount of random error from the measurement process that might be embedded in the scores . Scores that are highly reliable are accurate , reproducible , and consistent from one testing occasion to another . That is , if the testing process were repeated with a group of test takers , essentially the same results would be obtained . Various kinds of reliability coefficients , with values ranging between 0.00 ( much error ) and 1.00 ( no error ) , are usually used to indicate the amount of error in the scores . '' For example , measurements of people 's height and weight are often extremely reliable .

Kuwait Oxygen and Acetylene Company ( KOAC ) was founded in 1953 by the late Salim Al-Huneidi to manufacture oxygen and acetylene . It was the first industrial gas manufacturing plant in the Persian Gulf area . The company later expanded its product range to cover a broad spectrum of other industrial and medical gases .   In 1974 Kuwait Industrial Gases Corporation ( KIGC ) was established to cater essentially to the expanding petroleum industry and was therefore located in the Shuaiba Industrial Area in proximity to the main refineries and petroleum installations .   Later , in 1977 it diversified geographically to the United Arab Emirates by establishing Arabian Industrial Gases Co. ( AIGCO ) in Sharjah . A recent addition to the group in Kuwait is PWT ( International ) , a contracting company formed in partnership with PWT SpA of Italy , in the field of automatic pipe welding technology .   As the requirements of local economies grew , a number of ancillary trading companies and diversifications were established in both Kuwait and United Arab Emirates .

A `` Dear Colleague '' letter is official correspondence that is sent by a Member , committee , or officer of the United States House of Representatives or United States Senate and that is distributed in bulk to other congressional offices . A `` Dear Colleague '' letter may be circulated in paper form through internal mail , distributed on a chamber floor , or sent electronically .   `` Dear Colleague '' letters are often used to encourage others to cosponsor , support , or oppose a bill . `` Dear Colleague '' letters concerning a bill or resolution generally include a description of the legislation or other subject matter along with a reason or reasons for support or opposition . Senders or signatories of such letters become identified with the particular issue . `` Dear Colleague '' letters can also create an `` unofficial link '' in the Capitol Hill information chain .   Additionally , `` Dear Colleague '' letters are used to inform Members and their offices about events connected to congressional business or modifications to House or Senate operations . The Committee on House Administration and the Senate Committee on Rules and Administration , for example , routinely circulate `` Dear Colleague '' letters to Members concerning matters that affect House or Senate operations , such as House changes to computer password policies or a reminder about Senate restrictions on mass mailings prior to elections .   These letters frequently begin with the salutation `` Dear Colleague . '' The length of such correspondence varies , with a typical `` Dear Colleague '' running one to two pages .


Question: It's important to recognize that computational simulations are essentially complex chains of arithmetic operations akin to those executable by pocket calculators; thus, being purely hypothetical in nature, these models can't contribute empirical substantiation."

 Limitations of Computer Models in Scientific Inquiry
While computer models serve invaluable roles across numerous scientific disciplines, understanding their limitations remains crucial. Essentially, these models represent sophisticated chains of mathematical operations akin to those executable via handheld calculators—albeit exponentially larger and faster. They encapsulate theories rather than empirical data, rendering them purely hypothetical constructs incapable of constituting direct proof.
In essence, computer science delves deeply into both foundational principles governing information manipulation and pragmatic methodologies facilitating effective execution thereof. This discipline encompasses comprehensive studies aimed at elucidating underlying mechanisms enabling automated processing tasks alongside exploring scalability potentials within algorithmic frameworks. Specialists dedicatedly engaged herein concentrate predominantly upon conceptualizing novel computing paradigms whilst simultaneously addressing intricate issues pertaining thereto.
However, despite remarkable advancements achieved thus far, certain inherent constraints persistently plague contemporary modeling endeavors. Notably absent amongst these simulations lies tangible substantiation; instead, reliance solely upon conjectural premises prevails. Consequently, albeit immensely beneficial heuristically speaking, resultant outputs should invariably interpret cautiously lest unwarranted assumptions inadvertently propagate misinformation throughout respective communities concerned therein.

Richard Manning Karp ( born January 3 , 1935 ) is an American computer scientist and computational theorist at the University of California , Berkeley . He is most notable for his research in the theory of algorithms , for which he received a Turing Award in 1985 , The Benjamin Franklin Medal in Computer and Cognitive Science in 2004 , and the Kyoto Prize in 2008 .

Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment ( e.g. , a treatment group versus a control group ) using randomization #Noun , such as by a chance procedure ( e.g. , flipping a coin ) or a random number generator . This ensures that each participant or subject has an equal chance of being placed in any group . Random assignment of participants helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment . Thus , any differences between groups recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment .   Random assignment , blinding , and controlling are key aspects of the design of experiments , because they help ensure that the results are not spurious or deceptive via confounding . This is why randomized controlled trials are vital in clinical research , especially ones that can be double-blinded and placebo-controlled .   Mathematically , there are distinctions between randomization , pseudorandomization , and quasirandomization , as well as between random number generators and pseudorandom number generators . How much these differences matter in experiments ( such as clinical trials ) is a matter of trial design and statistical rigor , which affect evidence grading . Studies done with pseudo - or quasirandomization are usually given nearly the same weight as those with true randomization but are viewed with a bit more caution .

In mathematics and computing , a radix point ( or radix character ) is the symbol used in numerical representations to separate the integer part of a number ( to the left of the radix point ) from its fractional part ( to the right of the radix point ) . `` Radix point '' is a general term that applies to all number bases . In base 10 notation , the radix point is more commonly called the decimal point , where the prefix deci - implies base 10 . Similarly , the term `` binary point '' is used for base 2 .   In English-speaking countries , the radix point is usually a small dot placed either on the baseline or halfway between the baseline and the top of the numerals . In many other countries , the radix point is a comma placed on the baseline . It is important to know which notation is being used when working in different software programs .

In numerical analysis and linear algebra , LU decomposition ( where ` LU ' stands for ` lower upper ' , and also called LU factorization ) factors a matrix as the product of a lower triangular matrix and an upper triangular matrix . The product sometimes includes a permutation matrix as well . The LU decomposition can be viewed as the matrix form of Gaussian elimination . Computers usually solve square systems of linear equations using the LU decomposition , and it is also a key step when inverting a matrix , or computing the determinant of a matrix . The LU decomposition was introduced by mathematician Banachiewicz in 1938 .

The rational planning model is a model of the planning process involving a number of rational actions or steps . Taylor ( 1998 ) outlines five steps , as follows :  Definition of the problems and/or goals ;  Identification of alternative plans/policies ;  Evaluation of alternative plans/policies ;  Implementation of plans/policies ;  Monitoring of effects of plans/policies .  The rational planning model is used in planning and designing neighborhoods , cities , and regions . It has been central in the development of modern urban planning and transportation planning . The model has many limitations , particularly the lack of guidance on involving stakeholders and the community affected by planning , and other models of planning , such as collaborative planning , are now also widely used .   The very similar rational decision-making model , as it is called in organizational behavior , is a process for making logically sound decisions . This multi-step model and aims to be logical and follow the orderly path from problem identification through solution . Rational decision making is a multi-step process for making logically sound decisions that aims to follow the orderly path from problem identification through solution .

Relationalism is any theoretical position that gives importance to the relational nature of things . For relationalism , things exist and function only as relational entities . Relationalism may be contrasted with relationism , which tends to emphasize relations per se .

A `` Hello , World ! '' program is a computer program that outputs or displays `` Hello , World ! '' to a user . Being a very simple program in most programming languages , it is often used to illustrate the basic syntax of a programming language for a working program . It is often the very first program people write when they are new to a language .

Remote laboratory ( also known as online laboratory , remote workbench ) is the use of telecommunications to remotely conduct real ( as opposed to virtual ) experiments , at the physical location of the operating technology , whilst the scientist is utilizing technology from a separate geographical location . Remote laboratory comprehends one or more remote experiments .

In statistics , originally in geostatistics , kriging or Gaussian process regression is a method of interpolation for which the interpolated values are modeled by a Gaussian process governed by prior covariances , as opposed to a piecewise-polynomial spline chosen to optimize smoothness of the fitted values . Under suitable assumptions on the priors , kriging gives the best linear unbiased prediction of the intermediate values . Interpolating methods based on other criteria such as smoothness need not yield the most likely intermediate values . The method is widely used in the domain of spatial analysis and computer experiments . The technique is also known as Wiener -- Kolmogorov prediction , after Norbert Wiener and Andrey Kolmogorov .   The theoretical basis for the method was developed by the French mathematician Georges Matheron in 1960 , based on the Master 's thesis of Danie G. Krige , the pioneering plotter of distance-weighted average gold grades at the Witwatersrand reef complex in South Africa . Krige sought to estimate the most likely distribution of gold based on samples from a few boreholes . The English verb is to krige and the most common noun is kriging ; both are often pronounced with a hard `` g '' , following the pronunciation of the name `` Krige '' . The word is sometimes capitalized as Kriging in the literature .

Reuben Hersh ( born 1927 ) is an American mathematician and academic , best known for his writings on the nature , practice , and social impact of mathematics . This work challenges and complements mainstream philosophy of mathematics . ( `` Hersh '' is his professional or `` pen '' name . His family name is Reuben Laznovsky . )   After receiving a B.A. in English literature from Harvard University in 1946 , Hersh spent a decade writing for Scientific American and working as a machinist . After losing his right thumb when working with a band saw he decided to study mathematics at the Courant Institute of Mathematical Sciences . In 1962 , he was awarded a Ph.D. in mathematics from New York University ; his advisor was P.D. Lax . He has been affiliated with the University of New Mexico since 1964 , where he is now professor emeritus .   Hersh has written a number of technical articles on partial differential equations , probability , random evolutions , and linear operator equations . He is the ( co ) author of four articles in Scientific American , and 12 articles in the Mathematical Intelligencer .   Hersh is best known as the coauthor with Philip J. Davis of The Mathematical Experience ( 1981 ) , which won a National Book Award in Science.This was the 1983 award for paperback Science .  From 1980 to 1983 in National Book Award history there were dual hardcover and paperback awards in most categories , and several nonfiction subcategories including General Nonfiction . Most of the paperback award-winners were reprints , including this one .   Hersh advocates what he calls a `` humanist '' philosophy of mathematics , opposed to both Platonism ( so-called `` realism '' ) and its rivals nominalism/fictionalism/formalism . He holds that mathematics is real , and its reality is social-cultural-historical , located in the shared thoughts of those who learn it , teach it , and create it . His article `` The Kingdom of Math is Within You '' ( a chapter in his `` Experiencing Mathematics , 2014 ) explains how mathematicians ' proofs compel agreement , even when they are inadequate as formal logic . He sympathizes with the perspectives on mathematics of Imre Lakatos and Where Mathematics Comes From , George Lakoff and Rafael Nunez , Basic Books .


Question: It's important to recognize that computational simulations essentially represent complex chains of arithmetic operations akin to those executable by basic calculators; hence, their nature remains purely hypothetical, disqualifying them as empirical proof in scientific inquiries. This underscores the need for caution when interpreting results derived from such models, emphasizing the distinction between theory and tangible observational data.

 Computer Models: Limitations & Role in Scientific Inquiry

Computer models serve as powerful tools in various scientific disciplines but should never overshadow critical thinking and empirical validation. These digital simulations essentially represent complex algorithms akin to those executed manually using calculators. Despite advancements, computer models remain inherently theoretical constructs; thus, they require careful interpretation rather than being treated as direct evidence. Scientists employ models to predict outcomes based on current understanding and data inputs. However, limitations arise since assumptions underpinning model design might oversimplify intricate real-world dynamics. Consequently, results generated solely through computational methods demand scrutiny against experimental findings before gaining credibility within academic communities. Historically, groundbreaking theories emerged independently of sophisticated modeling techniques—evidenced during Newtonian physics formulation predating modern computers' existence. Today’s reliance on technology facilitates exploration into uncharted territories yet simultaneously introduces biases reflective of programmer intent alongside hardware constraints. Therefore, while invaluable assets aiding hypothesis testing across diverse sectors ranging from meteorology to economics, computer models necessitate continuous refinement informed by observational feedback loops ensuring accuracy remains paramount amidst evolving paradigms shaping contemporary discourse around artificial intelligence capabilities versus traditional investigative methodologies grounded firmly upon reproducibility principles enshrined throughout history spanning ancient civilizations up till recent times characterized by exponential technological proliferation catalyzing paradigm shifts unparalleled heretofore witnessed hitherto mankind's tenure inhabiting terrestrial biosphere coexisting symbiotically albeit precariously balanced ecosystems perpetually threatened anthropogenic interventions exacerbated ongoing ecological crises manifesting myriad forms encompassing deforestation wildfires oceanic acidification biodiversity collapse etcetera ad infinitum...

The representation theory of groups is a part of mathematics which examines how groups act on given structures .   Here the focus is in particular on operations of groups on vector spaces . Nevertheless , groups acting on other groups or on sets are also considered . For more details , please refer to the section on permutation representations .   Please note , that except for a few marked exceptions only finite groups will be considered in this article . We will also restrain to vector spaces over fields of characteristic zero . Because the theory of algebraically closed fields of characteristic zero is complete , a theory valid for a special algebraically closed field of characteristic zero is also valid for every other algebraically closed field of characteristic zero . Thus , without loss of generality , we can study vector spaces over   Representation theory is used in many parts of mathematics , as well as in quantum chemistry and physics . Among other things it is used in algebra to examine the structure of groups . There are also applications in harmonic analysis and number theory . For example , representation theory is used in the modern approach to gain new results about automorphic forms .

Ready-to-wear or prêt-à-porter ( -LSB- ˌprɛt_ɑː_pɔrˈteɪ -RSB- , -LSB- pʁɛ.ta pɔʁ.te -RSB- ; often abbreviated RTW ; `` off-the-rack '' or `` off-the-peg '' in casual use ) is the term for factory-made clothing , sold in finished condition , in standardized sizes , as distinct from made to measure or bespoke clothing tailored to a particular person 's frame . Off-the-peg is sometimes used for items other than clothing such as handbags .   Ready-to-wear has rather different connotations in the spheres of fashion and classic clothing . In the fashion industry , designers produce ready-to-wear clothing , intended to be worn without significant alteration because clothing made to standard sizes fits most people . They use standard patterns , factory equipment , and faster construction techniques to keep costs low , compared to a custom-sewn version of the same item . Some fashion houses and fashion designers produce mass-produced and industrially manufactured ready-to-wear lines but others offer garments that are not unique but are produced in limited numbers .

Lattice model ( finance ) , a `` discrete-time '' model of the varying price over time of the underlying financial instrument , during the life of the instrument .  Lattice model ( mathematics ) , a regular tiling of a space by a primitive cell .  Lattice model ( biophysics ) , a class of Ising-type models for the description of biomacromolecules , their transformations and binding in gene regulation and signal transduction .

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 .

In mathematics , the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a function on Euclidean space . It is usually denoted by the symbols , , or . The Laplacian of a function at a point , up to a constant depending on the dimension , is the rate at which the average value of over spheres centered at deviates from as the radius of the sphere grows . In a Cartesian coordinate system , the Laplacian is given by the sum of second partial derivatives of the function with respect to each independent variable . In other coordinate systems such as cylindrical and spherical coordinates , the Laplacian also has a useful form .   The Laplace operator is named after the French mathematician Pierre-Simon de Laplace ( 1749 -- 1827 ) , who first applied the operator to the study of celestial mechanics , where the operator gives a constant multiple of the mass density when it is applied to a given gravitational potential . Solutions of the equation , now called Laplace 's equation , are the so-called harmonic functions , and represent the possible gravitational fields in free space .   The Laplacian occurs in differential equations that describe many physical phenomena , such as electric and gravitational potentials , the diffusion equation for heat and fluid flow , wave propagation , and quantum mechanics . The Laplacian represents the flux density of the gradient flow of a function . For instance , the net rate at which a chemical dissolved in a fluid moves toward or away from some point is proportional to the Laplacian of the chemical concentration at that point ; expressed symbolically , the resulting equation is the diffusion equation . For these reasons , it is extensively used in the sciences for modelling all kinds of physical phenomena . The Laplacian is the simplest elliptic operator , and is at the core of Hodge theory as well as the results of de Rham cohomology . In image processing and computer vision , the Laplacian operator has been used for various tasks such as blob and edge detection .

In mathematics , reduction refers to the rewriting of an expression into a simpler form . For example , the process of rewriting a fraction into one with the smallest whole-number denominator possible ( while keeping the numerator an integer ) is called `` reducing a fraction '' . Rewriting a radical ( or `` root '' ) expression with the smallest possible whole number under the radical symbol is called `` reducing a radical '' . Minimizing the number of radicals that appear underneath other radicals in an expression is called denesting radicals .

'' ` LAMP '' ' is an archetypal model of web service stacks , named as an acronym of the names of its original four open-source components : the Linux operating system , the Apache HTTP Server , the MySQL relational database management system ( RDBMS ) , and the PHP programming language . The LAMP components are largely interchangeable and not limited to the original selection . As a solution stack , LAMP is suitable for building dynamic web sites and web applications .   Since its creation , the LAMP model has been adapted to other componentry , though typically consisting of free and open-source software . For example , an equivalent installation on the Microsoft Windows family of operating systems is known as WAMP .

Representation theory is a branch of mathematics that studies abstract algebraic structures by representing their elements as linear transformations of vector spaces , and studies  modules over these abstract algebraic structures . In essence , a representation makes an abstract algebraic object more concrete by describing its elements by matrices and the algebraic operations in terms of matrix addition and matrix multiplication . The algebraic objects amenable to such a description include groups , associative algebras and Lie algebras . The most prominent of these ( and historically the first ) is the representation theory of groups , in which elements of a group are represented by invertible matrices in such a way that the group operation is matrix multiplication .   Representation theory is a useful method because it reduces problems in abstract algebra to problems in linear algebra , a subject that is well understood . Furthermore , the vector space on which a group ( for example ) is represented can be infinite-dimensional , and by allowing it to be , for instance , a Hilbert space , methods of analysis can be applied to the theory of groups . Representation theory is also important in physics because , for example , it describes how the symmetry group of a physical system affects the solutions of equations describing that system .   Representation theory is pervasive across fields of mathematics , for two reasons . First , the applications of representation theory are diverse : in addition to its impact on algebra , representation theory :  illuminates and generalizes Fourier analysis via harmonic analysis ,  is connected to geometry via invariant theory and the Erlangen program ,  has an impact in number theory via automorphic forms and the Langlands program .   Secondly , there are diverse approaches to representation theory . The same objects can be studied using methods from algebraic geometry , module theory , analytic number theory , differential geometry , operator theory , algebraic combinatorics and topology .   The success of representation theory has led to numerous generalizations . One of the most general is in category theory . The algebraic objects to which representation theory applies can be viewed as particular kinds of categories , and the representations as functors from the object category to the category of vector spaces . This description points to two obvious generalizations : first , the algebraic objects can be replaced by more general categories ; second , the target category of vector spaces can be replaced by other well-understood categories .

In mathematical logic and automated theorem proving , resolution is a rule of inference leading to a refutation theorem-proving technique for sentences in propositional logic and first-order logic . In other words , iteratively applying the resolution rule in a suitable way allows for telling whether a propositional formula is satisfiable and for proving that a first-order formula is unsatisfiable . Attempting to prove a satisfiable first-order formula as unsatisfiable may result in a nonterminating computation ; this problem does n't occur in propositional logic .   The resolution rule can be traced back to Davis and Putnam ( 1960 ) ; however , their algorithm required to try all ground instances of the given formula . This source of combinatorial explosion was eliminated in 1965 by John Alan Robinson 's syntactical unification algorithm , which allowed one to instantiate the formula during the proof `` on demand '' just as far as needed to keep refutation completeness .   The clause produced by a resolution rule is sometimes called a resolvent .

Recruitment ( hiring ) is a core function of human resource management . Recruitment refers to the overall process of attracting , selecting and appointing suitable candidates  for jobs ( either permanent or temporary ) within an organization . Recruitment can also refer to processes involved in choosing individuals for unpaid positions , such as voluntary roles or unpaid trainee roles . Managers , human resource generalists and recruitment specialists may be tasked with carrying out recruitment , but in some cases public-sector employment agencies , commercial recruitment agencies , or specialist search consultancies are used to undertake parts of the process . Internet-based technologies to support all aspects of recruitment have become widespread .


Question: It's important to recognize that computational simulations merely represent complex chains of arithmetic operations akin to those executable by simple calculators; thus, their nature remains purely hypothetical and should not constitute empirical proof in scientific discourse."

 Understanding Computer Models: Limitations & Theory
Computer models represent complex simulations based on algorithms and mathematical equations, essentially extended computations akin to those performed manually using calculators. These models serve various fields, facilitating predictions about weather changes, economic trends, engineering designs, among others. Despite their sophistication, involving high-speed processors and vast databases, computer models remain fundamentally theoretical constructs. They rely heavily on assumptions and simplifications of real-world phenomena, making them unsuitable for empirical proof. Consider meteorological forecasting; while models predict future conditions accurately sometimes, unexpected variables often lead to inaccuracies. Similarly, financial market simulators use historical data to forecast outcomes yet fail under unforeseen circumstances. Thus, although immensely useful tools aiding decision-making across industries—from healthcare diagnostics to space exploration—computer models' reliance on theory limits their evidentiary value in scientific inquiry without corroborating observational data.
The essence here revolves around recognizing how despite advancements enabling more detailed modeling capabilities compared even decades ago when rudimentary versions existed merely conceptualizing basic principles behind observed behaviors (like Newtonian physics applied universally), there exists inherent uncertainty tied directly back into foundational aspects concerning initial conditions fed into system plus subsequent iterations thereof leading down divergent paths depending upon minute differences initially overlooked potentially resulting catastrophic failure modes later stages development cycle thus highlighting critical importance validating results obtained through rigorous testing procedures ensuring reliability moving forward especially considering increasing dependence technology permeates every facet daily life ranging mundane tasks checking bank balance online shopping ordering food delivery services hailing rideshares managing household appliances controlling smart home environments monitoring health vitals tracking fitness goals learning new skills entertainment purposes communication social networking sharing experiences globally instantaneously transcending geographical boundaries language barriers cultural divides fostering interconnectedness unparalleled scale scope depth breadth humanity ever witnessed before now poised embark next phase evolution powered exponentially growing computing power artificial intelligence machine learning big data analytics cloud computing internet things blockchain distributed ledger technologies quantum computing nanotechnology biotechnology robotics automation augmented reality virtual reality mixed reality spatial computing immersive media content creation distribution platforms decentralized autonomous organizations tokenized economies fractional ownership non-fungible tokens metaverse ecosystems Web3 infrastructure layers zero-knowledge proofs homomorphic encryption multiparty computation secure multi-party protocols differential privacy federated learning explainable AI responsible innovation ethical governance sustainable development open-source collaboration cross-disciplinary research interdisciplinary education lifelong learning continuous improvement agile methodologies lean startup frameworks design thinking user experience customer journey mapping persona building storyboarding prototyping wireframing mockups usability tests A/B split variations multivariate experiments funnel analysis cohort retention churn lifetime value cost acquisition return investment net promoter score brand awareness loyalty advocacy evangelism virality network effects platform dynamics flywheel momentum

The Knights of the Lambda Calculus is a semi-fictional organization of expert Lisp and Scheme hackers . The name refers to the lambda calculus , a mathematical formalism invented by Alonzo Church , with which Lisp is intimately connected , and references the Knights Templar .   There is no actual organization that goes by the name Knights of the Lambda Calculus ; it mostly only exists as a hacker culture in-joke . The concept most likely originated at MIT . For example , in the Structure and Interpretation of Computer Programs video lectures , one of the lecturers presents the audience with the button , saying they are now members of this special group . However , according to the Jargon File , a `` well-known LISPer '' has been known to give out buttons with Knights insignia on them , and some people have claimed to have membership in the Knights .

Demonstrative evidence is evidence in the form of a representation of an object . This is , as opposed to , real evidence , testimony , or other forms of evidence used at trial .

Language , Truth , and Logic is a 1936 work of philosophy by Alfred Jules Ayer . It brought some of the ideas of the Vienna Circle and the logical empiricists to the attention of the English-speaking world .   In the book , Ayer defines , explains , and argues for the verification principle of logical positivism , sometimes referred to as the criterion of significance or criterion of meaning . Ayer explains how the principle of verifiability may be applied to the problems of philosophy .

In the oil and gas industry , reservoir modeling involves the construction of a computer model of a petroleum reservoir , for the purposes of improving estimation of reserves and making decisions regarding the development of the field , predicting future production , placing additional wells , and evaluating alternative reservoir management scenarios .   A reservoir model represents the physical space of the reservoir by an array of discrete cells , delineated by a grid which may be regular or irregular . The array of cells is usually three-dimensional , although 1D and 2D models are sometimes used . Values for attributes such as porosity , permeability and water saturation are associated with each cell . The value of each attribute is implicitly deemed to apply uniformly throughout the volume of the reservoir represented by the cell .

A digital signature is a mathematical scheme for demonstrating the authenticity of digital messages or documents . A valid digital signature gives a recipient reason to believe that the message was created by a known sender ( authentication ) , that the sender can not deny having sent the message ( non-repudiation ) , and that the message was not altered in transit ( integrity ) .   Digital signatures are a standard element of most cryptographic protocol suites , and are commonly used for software distribution , financial transactions , contract management software , and in other cases where it is important to detect forgery or tampering .

In epistemology , rationalism is the view that `` regards reason as the chief source and test of knowledge '' or `` any view appealing to reason as a source of knowledge or justification '' . More formally , rationalism is defined as a methodology or a theory `` in which the criterion of the truth is not sensory but intellectual and deductive '' .   In an old controversy , rationalism was opposed to empiricism , where the rationalists believed that reality has an intrinsically logical structure . Because of this , the rationalists argued that certain truths exist and that the intellect can directly grasp these truths . That is to say , rationalists asserted that certain rational principles exist in logic , mathematics , ethics , and metaphysics that are so fundamentally true that denying them causes one to fall into contradiction . The rationalists had such a high confidence in reason that empirical proof and physical evidence were regarded as unnecessary to ascertain certain truths -- in other words , `` there are significant ways in which our concepts and knowledge are gained independently of sense experience '' .   Different degrees of emphasis on this method or theory lead to a range of rationalist standpoints , from the moderate position `` that reason has precedence over other ways of acquiring knowledge '' to the more extreme position that reason is `` the unique path to knowledge '' . Given a pre-modern understanding of reason , rationalism is identical to philosophy , the Socratic life of inquiry , or the zetetic ( skeptical ) clear interpretation of authority ( open to the underlying or essential cause of things as they appear to our sense of certainty ) . In recent decades , Leo Strauss sought to revive `` Classical Political Rationalism '' as a discipline that understands the task of reasoning , not as foundational , but as maieutic .   In politics , Rationalism , since the Enlightenment , historically emphasized a `` politics of reason '' centered upon rational choice , utilitarianism , secularism , and irreligion -- the latter aspect 's antitheism later softened by politic adoption of pluralistic rationalist methods practicable regardless of religious or irreligious ideology .   In this regard , the philosopher John Cottingham noted how rationalism , a methodology , became socially conflated with atheism , a worldview :

Knowledge of human nature is the ability to correctly assess the behavior or character of people based on a first impression , and to gauge how they think and predict how they will act .   Life experience , intuition , intelligence , and wisdom are the decisive factors which contribute to this ability . Knowledge of human nature is not innate , but is acquired through frequent contact with people and experience with many different people .   Knowledge of human nature can be used to judge people correctly , to motivate them , to give other people good advice , to deepen relationships , etc. . However , it can also be used to exploit people to one 's own advantage , for example , if one wants to persuade people , to seduce them , or to sell them something .   There are numerous models for the theoretical acquisition of knowledge of human nature , such as the Myers-Briggs Type Indicator or the Enneagram .

A random walk is a mathematical object , known as a stochastic or random process , that describes a path that consists of a succession of random steps on some mathematical space such as the integers . For example , the path traced by a molecule as it travels in a liquid or a gas , the search path of a foraging animal , the price of a fluctuating stock and the financial status of a gambler can all be approximated by random walk models , even though they may not be truly random in reality . As illustrated by those examples , random walks have applications to many scientific fields including ecology , psychology , computer science , physics , chemistry , biology as well as economics . Random walks explain the observed behaviors of many processes in these fields , and thus serve as a fundamental model for the recorded stochastic activity . As a more mathematical application , the value of pi can be approximated by the usage of random walk in agent-based modelling environment . The term random walk was first introduced by Karl Pearson in 1905 .   Various types of random walks are of interest , which can differ in several ways . The term itself most often refers to a special category of Markov chains or Markov processes , but many time-dependent processes are referred to as random walks , with a modifier indicating their specific properties . Random walks ( Markov or not ) can also take place on a variety of spaces : commonly studied ones include graphs , others on the integers or the real line , in the plane or in higher-dimensional vector spaces , on curved surfaces or higher-dimensional Riemannian manifolds , and also on groups finite , finitely generated or Lie . The time parameter can also be manipulated . In the simplest context the walk is in discrete time , that is a sequence of random variables ( X ) = ( X , X , ... ) indexed by the natural numbers . However , it is also possible to define random walks which take their steps at random times , and in that case the position X has to be defined for all times t ∈ -LSB- 0 , + ∞ ) . Specific cases or limits of random walks include the Lévy flight and diffusion models such as Brownian motion .   Random walks are a fundamental topic in discussions of Markov processes . Their mathematical study has been extensive . Several properties , including dispersal distributions , first-passage or hitting times , encounter rates , recurrence or transience , have been introduced to quantify their behaviour .


Question:
 Observations from satellites and ground-based instruments reveal that there's reduced radiation leakage into outer space within carbon dioxide absorption spectral bands. This indicates an enhanced greenhouse effect attributable to increased atmospheric CO2 concentrations.

Both claims convey the same idea: The increase in Carbon Dioxide levels has led to more heat being trapped by Earth’s atmosphere as measured through satellite data and observations on earth which show decreased outgoing longwave radiation (OLR) specifically around frequencies where CO2 absorbs light most efficiently - thus strengthening our planet’s natural insulation mechanism known popularly today under various names such as 'greenhouse' or simply 'warming'.

 Atmospheric Heat Trapping: Role of Carbon Dioxide
Carbon dioxide plays a critical role in trapping heat within Earth’s atmosphere, acting as a key component among greenhouse gases. These gases absorb and emit radiation in the thermal infrared spectrum, significantly influencing planetary temperatures. Water vapor, alongside CO2, methane, nitrous oxide, and ozone, form part of Earth's natural blanket, maintaining its habitable conditions; without them, Earth might experience average temperatures around freezing instead of the comfortable 15°C we enjoy now. Notably, Venus, Mars, and Saturn's moon Titan exhibit similar phenomena due to their respective greenhouse gas compositions.
Since pre-industrial times—around 1750—the atmospheric CO2 levels have surged approximately 40%, climbing from 280 parts per million (ppm) to roughly 406 ppm by early 2017. Despite nature's attempts to mitigate increases through "carbon sink" mechanisms involving forests, oceans, and soils, anthropogenic sources persistently add more. Burning fossil fuels – coal, oil, and gas – coupled with deforestation, land use changes, and agricultural practices contribute heavily to escalating concentrations.
Scientists predict that continuing emission trends will likely push Earth past historic temperature norms by mid-century, posing significant risks to ecological systems, biological diversity, and societal well-being globally. Projections indicate crossing a crucial 2°C warming threshold — deemed perilous by international consensus — possibly occurring before 2036 under unabated release scenarios. Urgent action is required to curb emissions and safeguard against irreversible impacts.

This response maintains comparable length, textual intricacy, and thematic alignment while preserving the original connection between claim and supporting information regarding increased CO2 leading to reduced heat escape into space.

Reciprocal length or inverse length is a measurement used in several branches of science and mathematics . As the reciprocal of length , common units used for this measurement include the reciprocal metre or inverse metre ( m − 1 ) , the reciprocal centimetre or inverse centimetre ( cm − 1 ) , and , in optics , the dioptre .   Quantities measured in reciprocal length include :  absorption coefficient or attenuation coefficient , in materials science  curvature of a line , in mathematics  gain , in laser physics  magnitude of vectors in reciprocal space , in crystallography  more generally any spatial frequency e.g. in cycles per unit length  optical power of a lens , in optics  rotational constant of a rigid rotor , in quantum mechanics  wavenumber , or magnitude of a wavevector , in spectroscopy  density of a linear feature in hydrology and other fields ; see kilometre per square kilometre

In cosmology , decoupling refers to a period in the development of the universe when different types of particles fall out of thermal equilibrium with each other . This occurs as a result of the expansion of the universe , as their interaction rates decrease ( and mean free paths increase ) up to this critical point . The two verified instances of decoupling since the Big Bang which are most often discussed are photon decoupling and neutrino decoupling , as these led to the cosmic microwave background and cosmic neutrino background , respectively .

Regional effects of global warming are long-term significant changes in the expected patterns of average weather of a specific region due to global warming . The world average temperature is rising due to the greenhouse effect caused by increasing levels of greenhouse gases , especially carbon dioxide . When the global temperature changes , the changes in climate are not expected to be uniform across the Earth . In particular , land areas change more quickly than oceans , and northern high latitudes change more quickly than the tropics , and the margins of biome regions change faster than do their cores .   Regional effects of global warming vary in nature . Some are the result of a generalised global change , such as rising temperature , resulting in local effects , such as melting ice . In other cases , a change may be related to a change in a particular ocean current or weather system . In such cases , the regional effect may be disproportionate and will not necessarily follow the global trend . The increasing temperatures from greenhouse gases have been causing sea levels to rise for many years .   There are three major ways in which global warming will make changes to regional climate : melting or forming ice , changing the hydrological cycle ( of evaporation and precipitation ) and changing currents in the oceans and air flows in the atmosphere . The coast can also be considered a region , and will suffer severe impacts from sea level rise .

Dark matter is matter that is undetectable by its emitted radiation , but whose presence can be inferred from gravitational effects .  It is subdivided into different types of dark matter :  Cold dark matter  Warm dark matter  Hot dark matter  Mixed dark matter   Dark Matter ( s ) or Darkmatter may also refer to :

The 13 centimeter , 2.3 GHz or 2.4 GHz band is a portion of the UHF ( microwave ) radio spectrum internationally allocated to amateur radio and amateur satellite use on a secondary basis . The amateur radio band is between 2300 MHz and 2450 MHz . The amateur satellite band is between 2400 MHz and 2450 MHz , and its use by satellite operations is on a non-interference basis to other radio users ( ITU footnote 5.282 ) . The license privileges of amateur radio operators include the use of frequencies and a wide variety of modes within these ranges for telecommunication . The allocations are the same in all three ITU Regions .   In the 2300-2400 MHz range the band is also allocated to the Mobile service on a Primary basis which in practice leads to some challenging sharing scenarios and inconsistent allocations to amateurs at national level .   Above 2400 MHz amateur stations must accept harmful interference caused by industrial , scientific , and medical equipment operating in the band . The most common ISM devices that operate in the band are microwave ovens .

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 .

A day is a unit of time . In common usage , it is either an interval equal to 24 hours or daytime , the consecutive period of time during which the Sun is above the horizon . The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day . Several definitions of this universal human concept are used according to context , need and convenience . In 1960 , the second was redefined in terms of the orbital motion of the Earth , and was designated the SI base unit of time . The unit of measurement `` day '' , redefined in 1960 as 86 400 SI seconds and symbolized d , is not an SI unit , but is accepted for use with SI . A civil day is usually 86 400 seconds , plus or minus a possible leap second in Coordinated Universal Time ( UTC ) , and occasionally plus or minus an hour in those locations that change from or to daylight saving time . The word day may also refer to a day of the week or to a calendar date , as in answer to the question , `` On which day ? '' The life patterns of humans and many other species are related to Earth 's solar day and the day-night cycle ( see circadian rhythms ) .   In recent decades the average length of a solar day on Earth has been about 86 400.002 seconds ( 24.000 000 6 hours ) and there are about 365.242 2 solar days in one mean tropical year . Because celestial orbits are not perfectly circular , and thus objects travel at different speeds at various positions in their orbit , a solar day is not the same length of time throughout the orbital year . A day , understood as the span of time it takes for the Earth to make one entire rotation  with respect to the celestial background or a distant star ( assumed to be fixed ) , is called a stellar day . This period of rotation is about 4 minutes less than 24 hours ( 23 hours 56 minutes and 4.1 seconds ) and there are about 366.242 2 stellar days in one mean tropical year ( one stellar day more than the number of solar days ) . Mainly due to tidal effects , the Earth 's rotational period is not constant , resulting in further minor variations for both solar days and stellar `` days '' . Other planets and moons have stellar and solar days of different lengths to Earth 's .

The Lunar Crater Observation and Sensing Satellite ( LCROSS ) was a robotic spacecraft operated by NASA . The mission was conceived as a low-cost means of determining the nature of hydrogen detected at the polar regions of the moon . Launched immediately after discovery of lunar water by Chandrayaan-1 , the main LCROSS mission objective was to further explore the presence of water ice in a permanently shadowed crater near a lunar polar region . It was successful in confirming water in the southern lunar crater Cabeus .   It was launched together with the Lunar Reconnaissance Orbiter ( LRO ) on June 18 , 2009 , as part of the shared Lunar Precursor Robotic Program , the first American mission to the Moon in over ten years . Together , LCROSS and LRO form the vanguard of NASA 's return to the Moon , and are expected to influence United States government decisions on whether or not to colonize the Moon .   LCROSS was designed to collect and relay data from the impact and debris plume resulting from the launch vehicle 's spent Centaur upper stage ( and data collecting Shepherding Spacecraft ) striking the crater Cabeus near the south pole of the Moon .   Centaur had nominal impact mass of 2,305 kg ( 5,081 lb ) , and an impact velocity of about 9000 km/h , releasing the kinetic energy equivalent of detonating approximately 2 tons of TNT ( 8.86 GJ ) .   LCROSS suffered a malfunction on August 22 , depleting half of its fuel and leaving very little fuel margin in the spacecraft .   Centaur impacted successfully on October 9 , 2009 , at 11:31 UTC . The Shepherding Spacecraft descended through Centaur 's ejectate plume , collected and relayed data , impacting six minutes later at 11:37 UTC .   Contrary to media reports at the time , neither the impact nor its dust cloud could be seen from Earth , using the naked eye or telescopes .

A reduction drive is a mechanical device to shift rotational speed . A planetary reduction drive is a small scale version using ball bearings in an epicyclic arrangement instead of toothed gears .   Reduction drives are used in engines of all kinds to increase the amount of torque per revolution of a shaft : the gearbox of any car is a ubiquitous example of a reduction drive . Common household uses are washing machines , food blenders and window-winders .   Planetary reduction drives are typically attached between the shaft of the variable capacitor and the tuning knob of any radio , to allow fine adjustments of the tuning capacitor with smooth movements of the knob . Planetary drives are used in this situation to avoid `` backlash '' , which makes tuning easier . If the capacitor drive has backlash , when one attempts to tune in a station , the tuning knob will feel sloppy and it will be hard to perform small adjustments . Gear-drives can be made to have no backlash by using split gears and spring tension but the shaft bearings have to be very precise .

The Low Energy Gamma-Ray Imager ( LEGRI ) was a payload for the first mission of the Spanish MINISAT platform , and active from 1997 to 2002 . The objective of LEGRI was to demonstrate the viability of HgI2 detectors for space astronomy , providing imaging and spectroscopical capabilities in the 10-100 keV range .  LEGRI was successfully launched on April 21 , 1997 , on a Pegasus XL rocket . The instrument was activated on May 19 , 1997 . It was active until February 2002 .   The LEGRI system included the Detector Unit , Mask Unit , Power Supply , Digital Processing Unit , Star Sensor , and Ground Support Unit .

 Atmospheric Energy Balance Disruption Due to Increased Carbon Dioxide Levels

The delicate balance of Earth’s energy budget is being disrupted by rising levels of carbon dioxide, leading to significant impacts on global temperatures. Satellites orbiting above us alongside ground-based monitoring stations confirm what scientists had predicted: there's reduced emission of thermal radiation into outer space specifically within bands absorbed by CO2 molecules. These findings underscore humanity's pivotal role through increased burning of fossil fuels - releasing vast quantities of CO2 into air- causing enhanced greenhouse effect trapping additional warmth near earth's surface thus contributing mightily towards observed planetary heating trends during recent decades. Although various gases contribute significantly when considering overall radiative forcing mechanisms responsible behind current anthropogenic induced climate changes; none rival importance held by concentration increases associated solely with carbon dioxide molecule presence throughout stratosphere & troposphere alike! Understanding complex interactions amongst different components comprising total atmospheric composition remains crucial endeavor undertaken continuously across numerous scientific disciplines aiming unravel mysteries governing future trajectories concerning ecological stability outcomes globally speaking...

Additionally highlights ongoing interdisciplinary research endeavors dedicated elucidating intricate dynamics interplaying among diverse atmospheric constituents shaping broader implications regarding sustainability paradigms moving forward.

The Radiation Assessment Detector ( RAD ) is an instrument mounted on the Mars Science Laboratory Curiosity rover . It was the first of ten instruments to be turned on during the mission .

In communications systems , the return channel ( also reverse channel or return link ) is the transmission link from a user terminal to the central hub .   Return links are often , but not always , slower than the corresponding forward links . Examples where this is true include asymmetric digital subscriber line , cable modems , mobile broadband and satellite internet access .   The return channel need not use the same medium as the main channel . For example , some hybrid Internet access services use a one-way cable television system for the forward channel and a dial-up modem for the return channel .   Even when the return and forward channels use the same medium , their differences often dictate the use of very different data modulation and coding techniques . For example , in a star radio network , only the central hub transmits on the forward link , so channel access method is a consideration only on the return link .   The `` forward/return '' terminology is also used for spacecraft command and telemetry links . Because the return link carries telemetry , often including imagery , it is often orders of magnitude faster than the forward link that transmits only a few predefined spacecraft commands .   Return and forward channels are distinct from , and should not be confused with , uplinks and downlinks in satellite communication systems . For example , satellite internet access with  conventional bent-pipe transponders require a total of two uplinks and two downlinks . One uplink and downlink pair are used for the forward link from the central ground hub through the satellite to the user terminal , and another uplink/downlink pair are used for the return link from the user terminal to the central hub .

Radiation hardening is the act of making electronic components and systems resistant to damage or malfunctions caused by ionizing radiation ( particle radiation and high-energy electromagnetic radiation ) , such as those encountered in outer space and high-altitude flight , around nuclear reactors and particle accelerators , or during nuclear accidents or nuclear warfare .   Most semiconductor electronic components are susceptible to radiation damage ; radiation-hardened components are based on their non-hardened equivalents , with some design and manufacturing variations that reduce the susceptibility to radiation damage . Due to the extensive development and testing required to produce a radiation-tolerant design of a microelectronic chip , radiation-hardened chips tend to lag behind the most recent developments .   Radiation-hardened products are typically tested to one or more resultant effects tests , including total ionizing dose ( TID ) , enhanced low dose rate effects ( ELDRS ) , neutron and proton displacement damage , and single event effects ( SEE , SET , SEL and SEB ) .

Recessional velocity is the rate at which an astronomical object is moving away , typically from Earth . It can be measured by shifts in spectral lines or estimated by general reddening of a galactic spectra .   Galaxies outside our galaxy often have their recessional velocity calculated relative to the cosmic microwave background .

A redout occurs when the body experiences a negative g-force sufficient to cause a blood flow from the lower parts of the body to the head . It is the inverse effect of a greyout , where blood flows away from the head to the lower parts of the body . Usually , a redout will only ever be experienced by pilots , as planes are the most common devices that allow such negative g-forces to be exerted . Redouts are potentially dangerous and can cause retinal damage and hemorrhagic stroke .   The predominant theory on the red appearing in the visual field is not due to the actual blood flow to the eye . It is most likely due to the blood laden lower eyelid coming into the visual field due to the pull of negative-Gs .

In electronics , a remote control is a component of an electronic device used to operate the device wirelessly from a distance . For example , in consumer electronics , a remote control can be used to operate devices such as a television set , DVD player , or other home appliance , from a short distance . A remote control is primarily a convenience feature for the user , and can allow operation of devices that are out of convenient reach for direct operation of controls . In some cases , remote controls allow a person to operate a device that they otherwise would not be able to reach , as when a garage door opener is triggered from outside or when a Digital Light Processing projector that is mounted on a high ceiling is controlled by a person from the floor level .   Early television remote controls ( 1956-1977 ) used ultrasonic tones . Present-day remote controls are commonly consumer infrared devices which send digitally-coded pulses of infrared radiation to control functions such as power , volume , tuning , temperature set point , fan speed , or other features . Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel , track number , and volume . For many devices , the remote control contains all the function controls while the controlled device itself has only a handful of essential primary controls . The remote control code , and thus the required remote control device , is usually specific to a product line , but there are universal remotes , which emulate the remote control made for most major brand devices .   Remote control has continually evolved and advanced in the 2000s to include Bluetooth connectivity , motion sensor-enabled capabilities and voice control .

Remote Sensing is a monthly peer-reviewed open access academic journal focusing on research pertaining to remote sensing and other disciplines of geography . It was established in 2009 and is published by MDPI . The founding editor-in-chief was Wolfgang Wagner ( Vienna University of Technology ) until September 2 , 2011 , when he resigned over the journal 's publication of a paper co-authored by Roy Spencer , which had received significant criticism from other scientists soon after its publication . Since then , the editor-in-chief has been Prasad S. Thenkabail ( United States Geological Survey ) .

A resistojet is a method of spacecraft propulsion ( electric propulsion ) that provides thrust by heating a ( typically non-reactive ) fluid . Heating is usually achieved by sending electricity through a resistor consisting of a hot incandescent filament , with the expanded gas expelled through a conventional nozzle .   Resistojets have been flown in space since 1965 on board military Vela satellites . However , they only became used in commercial applications in 1980 with the launch of the first satellites in the INTELSAT-V program . Many GEO spacecraft , and all 95 Iridium , used Aerojet MR-501 / MR-502 series resistojet engines . Nowadays resistojet propulsion is used for orbit insertion , attitude control , and deorbit of LEO satellites , and do well in situations where energy is much more plentiful than mass , and where propulsion efficiency needs to be reasonably high but low thrust is acceptable .

Resolved sideband cooling is a laser cooling technique allowing cooling of tightly bound atoms and ions beyond the Doppler cooling limit , potentially to their motional ground state . Aside from the curiosity of having a particle at zero point energy , such preparation of a particle in a definite state with high probability ( initialization ) is an essential part of state manipulation experiments in quantum optics and quantum computing .
