For the past several years, Leonard Susskind’s lectures and books have been one of the most important parts of my own physics self-study.
Like many people, I kept running into the same problem: the material was incredibly valuable, but it was scattered. Some notes existed only in old forum posts. Some PDF links had disappeared. Some supplemental courses were available as videos, but not as organized notes. Even when the material was still online, it was often difficult to browse as a coherent archive.
So I started keeping a repository for it:
This is not an official Stanford archive. It is a maintained study archive that brings together Leonard Susskind lecture notes, transcript collections, subtitle files, generated companion notes, and published PDFs in one place.
Table of Contents
What is in the repository
The repository currently includes:
- published PDF notes for several core and supplemental courses
- subtitle files for the lecture archive
- timestamped Markdown transcripts
- transcript-derived LaTeX notes and compiled course PDFs
- related companion material connected to The Theoretical Minimum
Some of the published PDF note sets now available there include:
- Advanced Quantum Mechanics
- Topics in String Theory
- Demystifying the Higgs Boson
- Particle Physics 1: Basic Concepts
- Particle Physics 2: Standard Model
- Particle Physics 3: Supersymmetry and Grand Unification
- Quantum Entanglement, Part 1

Why I kept working on it
This is not a random archive project for me.
Susskind’s lectures helped shape how I learned physics. I have been following his material for about six years, and it influenced not only my reading but also how I think about learning difficult subjects: start from physical meaning, build intuition carefully, and then return to the formalism with better questions.
At one point, that influence became concrete enough that I even published a paper partly inspired by ideas and habits of thought that grew out of reading his books.
That is why I kept maintaining the repository even when it was under-maintained for long stretches. The value of the material never really went away.
A new phase: AI-assisted curation
More recently, I started using my own Video2Book tooling and AI-agent workflows to help curate the archive more systematically.
That means:
- downloading and organizing lecture archives more cleanly
- transcribing lectures into subtitles and searchable Markdown
- generating structured companion notes course by course
- compiling those notes into readable PDFs
The goal is not to replace careful reading or real physics study. The goal is to make the archive more durable, searchable, and easier to build on.
If you are curious about the tooling side, that companion project is here:
Who this may help
This archive may be useful if you are:
- learning from The Theoretical Minimum
- looking for Leonard Susskind supplemental-course notes
- trying to study from video lectures more seriously
- building your own long-form lecture archive
- interested in AI-assisted knowledge curation for technical education
A small invitation
If you know of missing PDFs, cleaner scans, better sources, or corrections, I would be glad to improve the archive.
And if you care about physics education, long-form lecture preservation, or turning great lecture series into durable study material, I think there is still a lot more to build here.
The repository again:
I wanted to share it simply because it may save other people the same searching, link-chasing, and fragmented note-gathering that I had to do myself.
