Sitting in the Oakleys’ comfortable living room, with its solid Mission furniture and mementos of their world travels, Dr. Oakley said she believes that just about anyone can train himself to learn. “Students may look at math, for example, and say, ‘I can’t figure this out — it must mean I’m really stupid!’ They don’t know how their brain works.”

Her own feelings of inadequacy give her empathy for students who feel hopeless. “I know the hiccups and the troubles people have when they’re trying to learn something.” After all, she was her own lab rat. “I rewired my brain,” she said, “and it wasn’t easy.”

As a youngster, she was not a diligent student. “I flunked my way through elementary, middle school and high school math and science,” she said. She joined the Army out of high school to help pay for college and received extensive training in Russian at the Defense Language Institute. Once out, she realized she would have a better career path with a technical degree (specifically, electrical engineering), and set out to tackle math and science, training herself to grind through technical subjects with many of the techniques of practice and repetition that she had used to let Russian vocabulary and declension soak in.

Along the way, she met Philip Oakley — in, of all places, Antarctica. It was 1983, and she was working as a radio operator at the Amundsen-Scott South Pole Station. (She has also worked as a translator on a Russian trawler. She’s been around.) Mr. Oakley managed the garage at the station, keeping machinery working under some of the planet’s most punishing conditions.

She had noticed him largely because, unlike so many men at the lonely pole, he hadn’t made any moves on her. “You can be ugly as a toad out there and you are the most popular girl,” she said. She found him “comfortably confident.” After he left a party without even saying hello, she told a friend she’d like to get to know him better. The next day, he was waiting for her at breakfast with a big smile on his face. Three weeks later, on New Year’s Eve, he walked her over to the true South Pole and proposed at the stroke of midnight. A few weeks after that, they were “off the ice” in New Zealand and got married.

Dr. Oakley recounts her journey in both of her best-selling books: “A Mind for Numbers: How to Excel at Math and Science (Even if You Flunked Algebra)” and, out this past spring, “Mindshift: Break Through Obstacles to Learning and Discover Your Hidden Potential.” The new book is about learning new skills, with a focus on career switchers. And yes, she has a MOOC for that, too.
