A note on how this book is written

The lecture notes collected here are drafted with the assistance of large language models and curated by the instructor. This is a deliberate experiment, and it is also why a portion of your grade rewards written knowledge contributions: if you find an error, an omission, or something that could simply be explained better, submit a correction. Details are in the Syllabus.
