e^(i x pi)= -1

I almost got a hardon the first time I saw that, almost.

For the programmers who might be reading this:

cmath.exp(1.j * cmath.pi) == -1. ;

Let the math arousal continue:

Wow, lots of π fans. e has a simple and elegant definition: The summation of the inverse of n factorial as n runs from 0 to infinity. Or you can call it the limit as n approaches infinity, of (1+1/n)n. Or even the limit as n approaches 0, of (1+n)(1/n). With π, you're either doing crazy continued fractions, or you're calling it the ratio of a circle's circumference to its diameter, and that's boring! Euler talked about e as being a number whose hyperbolic logarithm was 1. Now that's fascinating!

That is called "Euler's Identity," and it an amazingly fascinating theorum, because it makes use of 0,1,i,e and π.

I remember reading something about a school of thought inspired by Buddhism in which mathematician did not use zero but used a blank space or something. It's a bit blurry, perhaps somebody knows what I'm referring to.

My only mathematical constant is "how the hell much do we each have to tip?"

My second favorie is phi. It's astonishing how many places it turns up. Even the structure of DNA.

But number one on my list of favorite constants is the reduced Planck's constant "h bar". It's the metric that defines the base of the scale for the size of literally everything in the universe.

The first part of my username refers to it. The second part refers to the unfortunate boxed feline that belonged to Schrodinger.

I have a cat named Schrodinger.

I just mentioned in a FaceBook comment last night that if I ever get another cat, he will be named Shrodinger.

At first glance, I thought this was a thread about whether I prefer Pie or Ecstasy.

Almost as hot as c = 1/root [mu-0 x E-0]

(Mu-0 being the permeability of free space and E-0 being the permittivity of free space)

"Class- what is the formula used to calculate the area of a circle?"

"ΠrČ"

Then, some kid in the back row said "No, pie are round, cake are square!"

I like pi but I always liked Avogadro's Number, for some reason.

I think I know, now, how you mathematicians may feel when we English nerds do our thing.

Lets not forget Newtons Universal Gravitational Constant, verified by Cavendish and used, about 200 years ago, to 'weigh the Earth'.

Much less awesome, but it was still fun, I remember doing that in a math lab:

I had one of those moments of revelation in science back in high school when I discovered that the formulas for calculating the gravitational force or the electrical force between two objects are virtually identical. Theonly difference being the units and the value of the constant.

The universe is not put together willy-nilly. Everything is interconnected and the structure hidden within can best be described as. . . . elegant.
