Ramanujan's Easiest Formula
A while ago I decided to figure out how to prove one of Ramanujan’s formulas. I feel this is the sort of thing every mathematician should try at least once. I picked the easiest one I could f…

What Gödel Discovered
In 1931, a 25-year-old Kurt Gödel wrote a proof that turned mathematics upside down. The implication was so astounding, and his proof so elegant that it was...kind of funny. I wanted to share his discovery with you. Fair warning though, I’m not a mathematician; I’m a programmer. This means my understanding is…

Empathy and perspective taking: How social skills are built
Being able to feel empathy and to take in the other person's perspective – these are two abilities through which we understand what is going on in the other person's mind. Although both terms are in constant circulation, it is still unclear what exactly they describe and constitute. Scientists at the Max Planck…

SLS vs. Starship
NASA just announced the lunar landers for the Artemis program. To everyone’s surprise, SpaceX’s massive Starship is one of three landers NASA chose alongside Blue Origin and Dynetics. Understandably, this is bringing up a lot of questions. Some of which we will answer in my next video/article: “Should NASA just cancel…

TeXmacs 1.99.14 released. Take a look at this research paper exported to HTML
Assuming a widely-believed hypothesis concerning the least prime in an arithmetic progression, we show that two -bit integers can be multiplied in time on a Turing machine with a finite number of tapes; we also show that polynomials of degree less than over a finite field with elements can be multiplied in time …

Study helps explain why motivation to learn declines with age
MIT neuroscientists have identified a brain circuit critical for learning to make decisions that require evaluating the cost or reward of an action. They showed this circuit is negatively affected by aging and in Huntington’s disease.
