This isn’t really a book but rather lecture notes. That’s what students see as the lectures are being written on a tablet. Usually, what’s said is just as important as what’s written, so it’s not surprising that it may be hard to read if you go too fast. I saw him do this a couple of years ago and it inspired me to try it myself. My handwriting isn’t nearly as good as his so I have to transcribe the lectures into TeX.
