How much do you remember about high school and college level math? I’ve designed a few quizzes that you can use to test yourself on your math skills. See how much you remember. And if you’re in high school or college and you’re currently learning these things, then maybe this could serve as an exercise for you.
I have started a series of Youtube videos about rationality based on Steven Pinker’s book Rationality: What It Is, Why It Seems Scarce, Why It Matters (see my review of the book here). The videos explain what rationality is, how to use it correctly, and how it goes wrong.
