A power modulo N

I describe how integer powers behave in modular arithmetic exploring congruence, repetition and related theorems.

Rope a ball

I find a really simple and secure way to attach a rope around a ball.


I figure an algorithm for calculating simplex coordinates


What is a permutation? How do I loop through permutations? How many generators are required for the symmetric group?

Energy matters

I layout some admirable equations for physics of relativity.

Borel distribution

Calculus tests how much work my imagined busy worker will do before his next break.

Deriving the Borel distribution

Poisson queue explodes under benchmark development. Benchmark tests were too realistic to accept on its face. Deriving probabilities takes time from my mental queue!

Coprime stars

Making stars explode — I recursively find order to the list of all rational numbers.
