Reference that explains general relativity

Click For Summary

Discussion Overview

The discussion revolves around finding references that explain Einstein's formulation of gravity, particularly focusing on the metric, Christoffel symbols, Riemann curvature tensor, and the vierbein and spin connection formalism. Participants seek resources that are accessible yet informative for understanding these concepts in general relativity.

Discussion Character

  • Homework-related
  • Technical explanation

Main Points Raised

  • One participant requests suggestions for simple references to explain Einstein's formulation of gravity, including specific mathematical components.
  • Another participant recommends the first chapter of "Introduction to 3+1 Numerical Relativity" by Miguel Alcubierre as a concise summary, noting that while the book focuses on numerical implementations, the introduction is particularly useful.
  • Sean Carroll's talks are mentioned as potentially helpful resources for understanding the topic.
  • A participant expresses satisfaction with Alcubierre's book for understanding the metric formulation of gravity and inquires about similar resources for learning about vierbeins.
  • Additional resources suggested include lectures by Alex Maloney and Susskind's General Relativity lectures available on YouTube, with a note that Alcubierre's book becomes advanced after the first chapter.
  • Links to other resources related to general relativity are shared, indicating a variety of materials available for further exploration.

Areas of Agreement / Disagreement

Participants generally agree on the usefulness of the recommended resources, but there is no consensus on a singular best reference for the vierbein concept, as inquiries for additional recommendations remain open.

Contextual Notes

Some participants note that while certain resources are helpful, they may require prior knowledge of the material to fully benefit from them. There is also an acknowledgment that the complexity of some texts increases significantly beyond introductory chapters.

Hi guys,

I need to write few paragraphs to explain Einstein's formulation of gravity in terms of the metric, christofell symbols, and Reimann curvature tensor. I also want to write about the veirbein and spin connection formalism of gravity.
Can anyone suggest good, yet simple references that i might use for this purpose? thank you!

One of the best concise summaries of GR that I've ever seen is the first chapter of the book "Introduction to 3+1 Numerical Relativity", by Miguel Alcubierre. The book itself is not what you are after becasue it is about numerical implementations, but the introduction is excellent as a summary. The nice thing is that some pages of the first chapter are available to read at Amazon. So you can quickly scan this to see if it's what you want. In my view, the price of the book is worth the first chapter alone.

Thank you stevenb, i had a look at the Alcubierre's book. it is exactly what i want to understand the formulation of gravity in terms of the metric. Do u know of any book that would introduce the concept of veirbeins in an analogous manner?
 
Daverz i had a look at the notes written by Caroll, but i don't know why i do not have access to the videos. Thanks anyways:)

Caroll's book is also good and more complete than his notes. There is also the Alex Maloney lectures at

http://www.physics.mcgill.ca/~maloney/514/

There are many other good books and Dr. Maloney recommends some in his lectures.

And, youtube has the Susskind GR lectures. You can find it easiliy if you do a search on youtube "Susskind General Relativity Lecture".

Note that the Alcubierre's book is very advanced after chapter 1, and the first chapter summary is only good as a concise reference once you understand the material. However, I wish I had that summary when I was learning the basics because it provides a good roadmap while learning and a great refresher course if you want to go back and relearn after not using it for a few years. I also wish I had those Susskind lectures because he has a gift for making the subject easy, which it actually is (at least conceptually) if taught correctly and studied diligently.
