Understanding Einstein's General Relativity: A Simplified Approach

Click For Summary

Discussion Overview

The discussion revolves around understanding Einstein's General Theory of Relativity (GR), with participants seeking explanations, resources, and recommendations for studying the theory. The scope includes conceptual clarifications and suggestions for appropriate literature based on varying levels of mathematical and physical background.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant asks for a clear explanation of General Relativity, expressing uncertainty about the topic.
  • Another participant summarizes GR as a theory of gravitation, describing it as the curvature of space-time geometry caused by matter.
  • Several participants recommend specific books for understanding GR, including "The Meaning of Relativity" by Albert Einstein and "Spacetime Physics" by Taylor and Wheeler.
  • A participant expresses a desire to understand GR well enough to perform calculations in a simplified two-dimensional context, indicating their background in single variable calculus and Euclidean geometry.
  • Some participants note that GR may not be particularly interesting in a 1+1 dimensional framework but still acknowledge the participant's goal of exploring the theory without extensive mathematics.

Areas of Agreement / Disagreement

Participants generally agree on the importance of foundational knowledge in special relativity (SR) before tackling GR, but there are differing opinions on the suitability of studying GR in reduced dimensions. The discussion remains unresolved regarding the best approach for learning GR based on individual backgrounds.

Contextual Notes

Limitations include varying levels of mathematical understanding among participants and the potential complexity of GR that may not be fully addressed in simplified contexts.

Hello,

This question has been bothering me and I haven't been able to get a correct and certain answer. So if somebody could please help me that would be great!
Here is my question:

What is the General Theory Of Relativity??



So if sombody could please explain this to me it would be extremely, greatly appreciated!

If you want to learn about GR, please tell us about your background in math and physics so that we can point you at a book that is at the right level for you.
 
I will summarize General Relativity in simple words. Basically, it's a theory of gravitation --at the macroscopic level.
IN GR, gravitation is due to the curvature which matter creates in the field of space-time geometry. The field of space-time geometry is the gravitational field.
The best book for understand SR and GR is: Albert Einstein, The meanng of Relativity. After that you can read and understand any thing on GR and SR.
Good luck.
 
Thank you so much for these replies it really helped me! I will definitely read the book "Albert Einstein, Then Meaning of Relativity".

Thanks.
 
To Allojubrious -
Einstein's "The Meaning of Relativity" should help you in knowing how an Einstein thinks.

I would like a book recommendation, please!

I have a good understanding of rudimentary single variable calculus and Euclidean geometry in Cartesian coordinates. My goal is to understand GR well enough to do some actual calculations with it and to produce an example of it with only two dimensions: a single spatial dimension and the temporal one...

Thank you!

GR actually isn't very interesting in 1+1 dimensions. But anyway, I understand what you mean: you want to do some GR without diving into massive mathematics. If you don't already have a firm knowledge of SR, I'd suggest reading Spacetime Physics by Taylor and Wheeler first. Then you might want to try Exploring Black Holes by Taylor and Wheeler or Gravity by Hartle.

I'm sorry, I forgot to mention that I do have a firm understanding of SR, so I will look into your latter recommendations. Thank you...
