**Note:** GR Marathon #8 will be happening at 14:0

Howdy! This page will be dedicated for the "General Relativity Marathon", a magical secret seminar that will happen every **Saturday** in **RIII Seminar Room** at a time that is usually announced here.

**You can find the lecture notes prepared for this seminar here (click). They will be updated regularly.**

The topic of this seminar is **The theory of general relativity**. I'll be updating this page with relevant material: mainly the lectures notes I'll be writing for this seminar, as well as presentation slides when needed, some resources/links/books and whatever I found to be of aid in my understanding of the theory. Let's see how this goes!

...

- What is a Tensor? , What is a Manifold? , What is General Relativity? series by XylyXylyX: Excellent, very highly recommended. The first two series introduces the mathematics with GR in mind. They're pretty long (130+ hours in total, or 60+ hours if you watch at 2x), but very comprehensive. They tend more towards the mathematical side. The last of them "What is General Relativity" is still ongoing to this date.
- General Relativity by Alexander Maloney: A graduate course on general relativity. I enjoyed these a lot.
- General Relativity by Leonard Suskind: Only 10 lectures. Very popular. I find them OK.
