Summer of Math Exposition #2 was finally announced. Deadline is August 15, 2022, which fits in quite well with my summer plans -- it's all in between the Florida trip and the other Florida trip.
I could do the next logical step from Exponential beats All. This one was supposed to be a quick explainer for my real video idea, why a rocket doesn't need a heat shield.
Or, I could do a visualization of the Kalman filter. There are of course lots of interesting visualizations to do, but the one I am interested in is showing off the Kalman gain, as the gain matrix which is a linear unbiased estimator, and demonstrating that picking other values for the gain will necessarily produce larger covariance.
Eventually I plan on doing both, but I am leaning towards the "why doesn't a rocket need a heat shield" video. It's more physics and less math, but "math" is given an especially wide breadth in Some2.
