The hyperfinite timeline

Take an interval. Cut it into H pieces, where H is hyperfinite. This serves as the index set of a stochastic process, among many other uses. Imagine that for each of the H steps, you flip a coin to get -1 or +1. Then move an infinitesimal distance left or right based on the sign. This is Brownian motion. Each infinitesimal piece of the timeline is profitably thought of as a Planck time.

What it's like to dissect a cadaver


A Prince, a Pauper, Power, Panama

Instrumental convergence is an issue I think about a lot because it’s so natural. Being rich and powerful almost never works against you.

Braindead Way to Derive Taylor Series of Exponential Function

\(e^x\) was first defined by a formula for continuous compound interest:

What is the prime factorization of zero?

Fundamental theorem of arithmetic1: every whole number can be split into a product of prime numbers in a unique way.

  1. Which deserves its name more than any other fundamental theorem, even the fundamental theorem of calculus. 

Use of emphasis in speech

I spent the last hour looking and failing to find the paper that made this specific claim:

"Litany Against Fear" in Present Tense

I love the Litany, but think it could benefit from more present tense. A litany is an entreating. That’s why they’re recited over and over. It tells one how to treat something as they are currently experiencing it.

When it's time to party we will party hard

The best feeling in a party is just sinking into a chair and talking about whatever you feel like with another. The best feeling in a party is doing something you’ve never done before and finding you enjoy it, or glorious wipe out like in that motorbike scene in 10 Things I Hate About You. The best feeling in a party is discovering someone strange in the same ways as you and feeling understood and not broken but just different and being ok with that.
