Fast Multipole Methods

Help I’m trapped in a final projects factory!

Fortunately this semester I have no final exams, just five freaking final projects. One of them was due last week and already graded, so I’m publishing it on this website here. It’s a Pluto notebook and has some flashy visualizations, but it’s honestly pretty light on substance, although it did get a grade of 100%. I probably wasted too much time playing with trying to find stable 3-body configurations. You can either download the notebook and run it in Pluto.jl, or copy the link and run it on Binder.

Floats Are Weird

Floats are weird. Anyways, here’s a basic calculus exercise:

\[\lim_{x \to 0} \frac{e^x-1}{x} = 1\]

However, I won’t prove that limit here, because this is a post about floats being weird, not a post about calculus. Instead, let’s try to approximate this limit numerically using Python, because what’s the worst that could happen? Let’s write that fraction as a Python function and plug in smaller and smaller $x$.

Asian Bayesian

Recently, I noticed that “Bayesian”, as in Bayesian statistics or Bayesian inference, sounds very close to “Asian”. Pun potential!

“I prefer Bayesian models over Asian models.”
