Genetically engineering virus-immune bees
This is a post I wrote outside my comfort zone, mainly because I was having serious writer’s block about writing things inside my comfort zone. I think everything I wrote is correct, but who am I to judge? Because there’s literally nothing else interesting or important going on in the world right now, I thought …

Self-organized criticality: the potential and problems of a theory of everything
Note: this essay is outside of my comfort zone, so there might be a few mistakes. I relied a lot on this paper and Wikipedia to help me think about it. Mistakes are my own. The 1987 paper “Self-organized criticality: An explanation of the 1/f noise”, by Bak, Tang, and Wiesenfeld has 8612 citations. That …

How to fix how people learn calculus: make calculus exciting again
Most people who take a calculus course never really learn calculus. They have only a hazy grasp of how the pieces fit together. Sure, they might be able to tell you that the derivative of x^2 is 2x, but ask them why and you’ll get a blank look. They learned to mask their confusion with …

Why most intro philosophy courses feel useless and how to fix them
Introduction to philosophy tends to be a useless class. At its best, it tends to feel like a drier version of the stuff you argue about with your friends while high. At its worst, it feels like listening to high people argue while you’re sober. Neither one makes you feel like you’ve accomplished that much …

Lessons in business from the golden age of advertising
I previously wrote a post on lessons in marketing from the golden age of advertising in early 20th century America, which I think went pretty well. Unfortunately (but fortunately), there are more great stories from the admen than can be fit in such a restrictive format. So, here’s my attempt at relaying them. For this …

Using the techniques of the Mad Men to market a SaaS
I love reading about advertising in the early 20th century. It’s one of my favorite subjects, and it’s way too often neglected by the Internet at large. Part of it is just a fascination with the ambition of those early admen. It was truly fitting for that age of great works. While bridges and skyscrapers …

Using spaced repetition flashcards to learn pretty much anything
Flashcards are an incredibly useful learning tool. In fact, they can be used to learn pretty much anything. That’s why it’s a pity that so few people use flashcards to their full potential. Flashcards can be used to learn pretty much anything, because, in short, remembering is essential to learning. Once something is taught to …

How to make a tutoring log
When you’re tutoring, it’s important to keep track of what exactly you’ve taught your students, when you taught them, and their progress. If you don’t keep track of this, then each session you’ll come in not knowing what to cover next. Your students will be unhappy with your lack of preparation, and you’ll be frantically …
