INFORMATION PHYSICS COURSE

​

I have taught this course repeatedly since 2005. Here you will find the course as taught in the Fall 2020 semester (UAlbany course listing Phy 425/525). It is geared towards physics graduate and advanced undergraduate students.

​

The course consists of 27 lectures and is roughly divided into two parts. Lectures 1-12 and 16-20 concentrate on inference (probability, entropy, and information) and should be accessible to people comfortable with advanced calculus. The second part (Lectures 13-15 and 21-27) concentrate on the foundations of statistical mechanics and quantum mechanics. These lectures assume a knowledge of statistical and quantum mechanics at the advanced undergraduate level.

​

The course syllabus includes the links to the videos and lecture notes. Course syllabus

 

The material in this course is presented in the (still unfinished) book "Entropic Physics: Probability, Entropy, and the Foundations of Physics.”
