We want to understand well known important mathematical results better, by exploring different interpretations, different generalizations, different proofs, similar results, appropriateness of naming conventions and notation, and of course, historical context.
All who are interested in either learning or teaching are welcome.

I'm always on the lookout for ways of visualizing mathematical results. In this essay I'm going to restrict myself to pictures. Furthermore, I'm going to
For quite a while, I knew of only one proof of the "infinitude of primes", namely Euclid's proof. Over the years, I've come across others, and I've noticed
The Fibonacci essay I mentioned a few days ago is done. There's now roughly twice the content than there was in the original incomplete version. As before,
Properties of Fibonacci numbers are often proved by induction. Although this results in technically correct proofs, I find that proofs by induction usually
... Welcome! ... Yes. ... They're kind of the same: they all involve one followed by some number of zeros. But, the NUMBER of zeros is QUITE different. Here's
