Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More ...

Research shows smart study beats long study for math formulas. Retrieval practice and spaced repetition are key. Quizzing helps more than re-reading. Spacing out reviews improves retention. Mixing ...

Mathematical formulas written over a hundred years ago could find an echo in the most current theories about black holes and turbulence. This observation links the work of the Indian Srinivasa ...
