What e Sounds Like

My EP featuring all four of my math based songs "What Math Sounds Like" drops today. Listen here: https://open.spotify.com/album/0MjBok...

This is the final installment of my mathemusical series.

The number e is a mathematical constant, approximately equal to 2.71828, which appears in many different settings throughout mathematics. It was discovered by the Swiss mathematician Jacob Bernoulli while studying compound interest, where e arises as the limit of (1 + 1/n)n as n approaches infinity.

The number e is of eminent importance in mathematics, alongside 0, 1, π and i. All five of these numbers play important and recurring roles across mathematics, and are the five constants appearing in one formulation of Euler's identity. Like the constant π, e is irrational: it is not a ratio of integers. Also like π, e is transcendental: it is not a root of any non-zero polynomial with rational coefficients. The numerical value of e truncated to 50 decimal places is
