What do I need before starting to learn electrodynamics?

Click For Summary

Discussion Overview

The discussion revolves around the prerequisites and resources for learning electrodynamics, particularly from the perspective of a high school sophomore preparing for Physics Olympiads. Participants share their experiences and suggest materials that could aid in understanding the subject.

Discussion Character

  • Exploratory
  • Technical explanation
  • Homework-related

Main Points Raised

  • One participant expresses a desire to learn electrodynamics and inquires about necessary prerequisites, indicating familiarity with calculus up to a level equivalent to standard Calculus 2.
  • Another participant suggests that vector calculus is essential for studying electrodynamics, questioning whether Calculus 2 includes this topic.
  • A participant mentions that the book 'Div, Grad, Curl, and All That' introduces vector calculus in the context of electrostatics, which could be beneficial for those unfamiliar with the subject.
  • There are recommendations for resources, including Kreyszig's book and 'Div, Grad, Curl, and All That', with a note on the availability of these materials in India.
  • One participant acknowledges their lack of knowledge in vector calculus and expresses intent to start learning it soon, seeking additional resource suggestions.

Areas of Agreement / Disagreement

Participants generally agree on the importance of vector calculus for studying electrodynamics, but there is no consensus on the specific prerequisites or the best resources, as different suggestions are offered.

Contextual Notes

Some participants express uncertainty about their current understanding of vector calculus and its relevance to electrodynamics, indicating a potential gap in knowledge that may affect their learning process.

Who May Find This Useful

High school students interested in physics, particularly those preparing for competitions like Physics Olympiads, as well as educators seeking resource recommendations for teaching electrodynamics.

I am a high school sophomore and I want to take part in Physics Olympiads which is exactly why I want to learn electrodynamics. I have ordered 'An Introduction to Electrodynamics' by D.J. Griffiths. I am halfway through MIT OCW mechanics course and I know Calculus equivalent to standard Calculus 2 courses. I am wondering if there are any prerequisites to learn Electrodynamics (at least in Physics). I also have Irodov Electrodynamics and I am not finding the book very hard to comprehend but it does not contain problems. I am truly enjoying this wonderful Physics journey.
Please tell me if I have to learn anything else before taking on the subject and also suggest good online resources. Thanks in advance :)

Not sure what Calculus 2 is. Is that Vector Calculus? You need vector calculus to study electrodynamics.
 
'Div, grad, curl, and all that' introduces vector calculus informally in the context of electrostatics which could be useful if you don't know vector calculus yet.

^ That's a great book. I got it for my son and he really liked it as he was taking his multivariable calculus class. I wish I had that book when I was going through my freshman year! :smile:

Unfortunately no, I haven't learned enough vector calc yet. Will start soon. Can you please name some nice resources? Thank you.

Sure. Kreyszig is a decent start. It will do fo what you are trying to do. You can pick one up for less than Rs. 500. Eswar.com has it.

Also, get Div, Grad, Curl and All that..

Not sure if it is available in India - perhaps you could check the library of a local college.
