Felling a Tree

I started cutting down a tree in my back yard in May of 2020. In May of 2023, I am still working on it. I got a big chunk of it done recently. It was kind of nerve wracking because I didn’t want to crush my fence, house or garage or power lines. It took some precision limb removal, but I’m now down to the main trunk. I’ll need a bigger saw.
Here is a drawing I made at the start of the project:

New Math Proof

Two high school students discovered a new proof for the Pythagorean Theorem. That is pretty exciting stuff.

One thing that caught my eye was the statement in this IFLScience story that their work had not yet been published, only presented at a conference and covered by a television news station. To my mind, the news story has “published” the proof. The idea is documented in the presentation slides and in the news story. We know the originators of where it came from and no other person who later writes it up in a paper should be able to steal credit for themselves.
