This short book is an elementary course on entropy, leading up to a calculation of the entropy of hydrogen gas at standard temperature and pressure. Topics covered include information, Shannon entropy and Gibbs entropy, the principle of maximum entropy, the Boltzmann distribution, temperature and coolness, the relation between entropy, expected energy and temperature, the equipartition theorem, th

I've been burned too many times by embracing open source products like this.We've been fed promises like these before. They will inevitably get acquired. Years of documentation, issues, and pull requests will be deleted with little-to-no notice. An exclusively commercial replacement will materialize from the new company that is inexplicably missing the features you relied on in the first place. Fo

This essay could probably benefit from some engagement with the literature on “interpretability” in LLMs, including the empirical results about how knowledge (like addition) is represented inside the neural network. To be blunt, I’m not sure being smart and reasoning from first principles after asking the LLM a lot of questions and cherry picking what it gets wrong gets to any novel insights at th
