As theCOVID-19 situation has unfolded, one thing that has helped me process what’s going on is a look at the basics of how experts are making predictions about the severity of the epidemic. I wrote up a little of my findings. Maybe this writeup will help you process too. You can find the writeup, which is a mix of math and code, on github. https://github.com/Yurlungur/mathematics-of-epidemics Stay safe out there, everyone. We’re all in this together.

Tidbit: Radio Waves Bouncing Off of an F-15
I’m afraid I don’t have time to write very much this week. So instead, I leave you with a little hint of the sort of thing I’m thinking about. The above picture is from a paper I just read. It shows a simulation of radio waves bouncing off of an F-15 fighter jet. The simulation was effected by first building the jet out of many tiny pyramids linked together at the faces (shown on the left). Then, a set of five waves or so was allowed to exist inside each pyramid. When you take all of these waves together,
