Theorems and Lemmas and Proofs, Oh My!

I was recently asked by a non-mathematician about the difference between the terms Theorem, Lemma, etc. My first reaction was I probably have a blog post on that...

Why I have some sympathy for the Simulation Theory (We are all characters in a video game.)

There are some people who believe that we are all characters in a video game written by Abisola (this is sometimes called The Simulation Hypothesis). I first dismissed...

Finding and answer to a math question: 1983 vs 2023.

In 1983, as a grad student, I knew that HALT \( \le_T \) KOLG but didn't know how to prove it. I asked around and A MONTH later through a series of connectionshere...

Can you put n pennies on an n x n chessboard so that all of the distances are distinct/how to look that up?

 In Jan 2023 I went to the Joint Math Meeting of the AMS and the MAA and took notes on things to look up later. In one of the talks they discussed a problem and...

There are an infinite number of proofs that there are an infinite number of primes

In the last few years there have been four papers that prove the primes are infinite using some number theory and some Ramsey Theory. The papers are:Van der Waerden...
