I want to learn special and general relativity

Click For Summary

Discussion Overview

The discussion centers on the best approaches to learning special and general relativity, particularly for individuals with limited prior knowledge in physics and mathematics. Participants share resources, personal experiences, and advice regarding the complexity of the subjects and the necessary prerequisites for a deeper understanding.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant expresses curiosity about the thoroughness of a Coursera course on relativity, noting it seems easy so far.
  • Another participant suggests supplementing the course with the first chapter of Morin's book, although they find some questions challenging.
  • Concerns are raised about the difficulty of Morin's book, with one participant indicating they are struggling with the material.
  • Some participants emphasize the need for a solid foundation in prerequisite math and physics to grasp the complexities of special and general relativity.
  • There is a discussion about the interconnectedness of physics topics, with one participant arguing that a broad knowledge base is necessary to understand relativity deeply.
  • Another participant mentions that general relativity is significantly harder conceptually and mathematically than special relativity.
  • One participant challenges the idea that one can learn a narrow aspect of physics without a comprehensive understanding of the broader subject.
  • There is a suggestion that learning the mathematics corresponding to relativity is essential for a complete understanding.

Areas of Agreement / Disagreement

Participants generally agree that a strong foundation in mathematics and physics is necessary to understand special and general relativity. However, there are differing opinions on the accessibility of the learning materials and the feasibility of mastering the subjects without extensive prior knowledge.

Contextual Notes

Some participants note the limitations of their current knowledge and the challenges posed by advanced texts, indicating that the discussion may not fully address the prerequisites needed for a comprehensive understanding of relativity.

Who May Find This Useful

This discussion may be useful for individuals interested in learning special and general relativity, particularly those with limited backgrounds in physics and mathematics seeking guidance on resources and study approaches.

Summary:: I want to learn special and general relativity

I am curious what is the best way to learn special and general relativity.

https://www.coursera.org/learn/einstein-relativity/home/info I started this course but it seems relativity easy so far. Only on week 2. Being easy is not bad I just curious it is thorough?

I don't know much about physics and only have precalculus education at the math level.
Any advice?

i think my end goal for relativity is to learn the math behind the hypothetical warp drive
Any advice?

The first chapter of Morin's book is online here. Might be a good supplement to coursera:

If you like Morin's style, you could purchase his book. You should definitely have at least one serious textbook.

So far I don't like Morin's book some of the questions are soul crushers.

Soul crushers? You mean self-esteem reducers?

I just mean very difficult and I am sinking too much time and not enough results for the time. I just made up a saying probably shouldn't.

It's bound to be hard. It's a serious undergraduate level subject.
 
After Morin's book what kind understanding will I have of special and general relativity? I think I will complete the coursea course first though.

You may have a complete understanding of SR. General Relativity is a different beast. It's much harder conceptually and especially mathematically.
 
Okay thanks for the advice.

I have taught both SR and GR to students in their fourth-fifth years of university. To master that level of course, which is what you will need in order to get a grasp of the math behind the Alcubierre warp deive, you will need the prerequisite math and physics courses. You therefore should not expect to get a hold of it without going through the requisites first.

That being said, you can get some idea about how things work from courses that are more of an orienting nature. However, it will not really be getting an understanding at a deeper level for the subject.

Don't know Morin's book. A pretty good undergraduate book is Hartle's Gravity, but I don't think precalculus alone will cut it.

If those problems are too difficult, you aren't ready for GR yet,.

There is this myth that one can learn just one narrow bit of physics, while ignoring the rest, and one can become good at it. Let me repeat, it is a MYTH!

I will tell you why that is exactly using SR/GR subject matter that you wish to learn. Let's focus just on SR. One of the most important aspect of SR is the covariant form of Maxwell equations. Now, already you will be in a conundrum, because I am guessing that (i) you don't know the physics of Maxwell equations and (ii) you do not have the mathematics to be able to understand and use Maxwell equations.

You may not encounter this issue when all you're doing is starting out in elementary SR that we teach students in a General Physics course. But your goal is rather ambitious, and it requires quite a bit of knowledge to achieve that. This means that you have to learn all there is to know about SR (and GR), and that has to included E&M and such, with all the corresponding mathematics.

There is a reason why every student in physics has to have a broad knowledge of Classical Mechanics, Quantum Mechanics, E&M, Thermodynamics/Statistical Mechanics, etc. Physics is often interconnected! My students found out about this the hard way where the subject matter than they are dealing with in the 2nd Semester of a General Physics course requires a lot of stuff they learned from the 1st Semester!

SR is not just basic mechanics of motion. It can't be just that. After all, Einstein delved into it because of the 19th century problem with the non-covariant aspect of Maxwell equations! So the historical impetus was already based on a topic from "another" subject area.

Physicists who specialized in SR/GR first became physicists. They learned physics, not just SR/GR. Only later, after they have a solid base of basic physics knowledge do they specialize in such field.

There are no shortcuts!

have they also specialized in the corresponding mathematics? if not, would you recommend that?
