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 ...

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 ...

Euler’s identity is an equality found in mathematics that has been compared to a Shakespearean sonnet and described as "the most beautiful equation." It is a special case of a foundational equation in ...

Mathematics is full of numbers that seem to keep popping up out of nowhere. Take pi, for instance, which appears in pretty much everything. Here's another one: Euler's constant. Also called the ...
