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.

Euler’s number is a mathematical constant with many applications in science and finance, usually denoted by the lowercase letter e.

At first glance, the multisets of positive integers that add to n, known as integer partitions, and Euler’s number e do not have much in common. However, if you take the reciprocal product of the ...
