Today I tried to write about the risk of passing the coronavirus when going to visit someone. It looked nice enough and I'm copying an edited version here, using KaTeX instead of the original LaTeX version I wrote. Also, I was experimenting with unicode symbol support, for which I used XeTeX.

I didn't make up the numbers that appear, but I haven't included the references either. It is just a simple note with no big pretension.

A few days ago John Conway died because of complications due to the coronavirus disease.

Many thoughts come to mind related to that.
