Euler’s Identity explained and the hope of order within chaos.

By: Cory Doctorow from London, UK, not my own body as I would have preferred. We were offered a test grade replacement if we got a physics tattoo my sophomore year of college. Verdict from my physics prof was that this is a math tattoo and therefore, not eligible.

Euler’s Equation gives me hope.

When I first saw it, it was written on a white board of my Calculus II class by a man I knew had written a lot of love letters in his life. He stepped back from the board after making quite the dramatically understated gesture, he pointed at it with his Expo marker and said,

“My God, that’s a sexy equation right there! Just really, pure elegance. “

I was hooked.

Euler’s equation connects the five most basic fundamental constants in the mathematical world in such a simple way that it just astounds and delights.

1 and 0 everyone knows. These are basic integers that refer to the presence of nothing or the presence of something. Everything about our counting and computing is based on 1s and 0s.

pi seems to have its own sex appeal all on its own. The ratio of any circle’s circumference to its diameter (3.1415….), this number is both constant and infinite and even has its own day, which I celebrate with as many round delicious food items as possible with other nerds. It’s infinite-ness makes it irrational. It’s simplicity makes it irresistible.

e is another irrational character, with a much less tantalizing source. Called…
