“Gentlemen, that is surely true, it is absolutely paradoxical; we cannot understand it, and we don’t know what it means. But we have proved it, and therefore we know it must be the truth.” —Benjamin ...

This video explores one of Leonhard Euler’s most elegant ideas, showing how factorials can be used to connect π, square roots, and one-half in a surprising and beautiful way. Through clear ...

What is it that makes Euler's identity, e]iPi + 1 = 0, so special? In Euler's Pioneering Equation Robin Wilson shows how this simple, elegant, and profound formula links together perhaps the five most ...

Glen Whitney, founder of the Museum of Math in New York, chose another geometrical theorem, this one having to do with the Euler line, named after 18th-century Swiss mathematician and physicist ...

Have you ever been curious about why the number e is so popular in math? Euler’s number, which is an infinitely long decimal, close to 2.71828, pops up naturally in a surprisingly broad range of ...

The Swiss mathematician Leonhard Euler (1707–83) was all but blind when he moved to St Petersburg in 1766 for a second stint as the star of the Russian Imperial Academy of Sciences. He had lost vision ...
