This is the first part of a two part series on Kepler's work. It's a wonderful work of pedagogy striking the pretty difficult balance between mathematical detail and pop science story telling.
The videos go into a surprising amount of detail; the second part has a lot of the key details of Kepler's New Astronomy -- something I haven't even found in standard textbook treatments (including the first part of the great Celestial Mechanics monograph by Shlomo Sternberg).
In the fact, this person's channel is truly a gem and very underrated. I find a lot of his videos match or even surpass other such channels like 3b1b or vertasium.
