Well, I’m back. I ended up taking a somewhat longer break than planned. I was just too discouraged to study last Thursday, and yesterday I was still getting settled again after being at camp. Today I watched YouTube videos in an attempt to ease into my project again. One was about the recent discovery of a new formula for approximating $\pi$. (It is not superior to existing formulae, just new.) The other was a fun video about some properties of prime numbers. It should be accessible to most people, and I have embedded it below.
Welcome back!
I admire that you have a self-designed and self-motivated project that you are pursuing.
