Why do computers only work with the numbers 0 and 1? There are machines that process three digits with more efficiency than ...

Understanding Euler’s Number (e) Euler’s number e is a mathematical constant that begins with 2.71828. Just like pi (π), it is non-terminating, which means it goes on and on.

Euler’s constant explains so much about math and physics. We delve into the number e, or Euler’s number, to find out why it’s so special.
