Discussion Overview

The discussion centers on the amount of special relativity (SR) knowledge required to effectively understand the textbook "Electricity and Magnetism" by Edward M. Purcell and David J. Morin. Participants explore the prerequisites for studying this material, particularly in the context of an upcoming electrodynamics course.

Discussion Character

  • Homework-related
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant expresses concern about fitting a full SR book into their study schedule, suggesting they have limited time before starting an electrodynamics course.
  • Another participant believes that the introductory chapter on SR in Freedman’s University Physics should suffice for understanding Purcell and Morin.
  • A different participant asserts that Purcell and Morin is suitable for those with a solid background in calculus and introductory electromagnetism, implying readiness for Griffiths without extensive SR knowledge.
  • One participant notes that they are not familiar with "A Student's Guide to Maxwell's Equations," but they successfully navigated Griffiths using a different main text, indicating that prior knowledge can vary in its adequacy.
  • Another participant critiques A.P. French's book on SR as being somewhat outdated, referencing a related thread for context.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the sufficiency of the SR material in Freedman’s University Physics for understanding Purcell and Morin. There are differing opinions on the necessity and adequacy of additional SR study.

Contextual Notes

Some participants express uncertainty about the effectiveness of their current resources and the implications for their upcoming coursework, highlighting the variability in individual preparation and understanding.

Who May Find This Useful

This discussion may be useful for students preparing for advanced studies in electromagnetism and those evaluating their readiness for related coursework in physics.

TL;DR Summary: How much special relativity Is needed for Edward M. Purcell & David J. Morin

It clearly is needed to fully understand this book and I have what seems like a good book that introduces relativity (A.P. French)

But I am not wanting to start it yet and it’s around 300 pages long, I have just finished A Students Guide to Maxwell’s Equations and have also intro E&M under my belt.

The reason for me wanting to carry on studying E&M and not start special relativity yet is because I start an electrodynamics course next October and I want to be over prepared, therefor I set myself a goal;
To read in this order;

Freedman’s University physics mechanics and electromagnetism chapters

A Students Guide to Maxwell’s Equations

Purcell & Morins Electricity and Magnetism

D.J Griffiths electrodynamics

I have read the first two, leaving me a year to read the last 2, which I think is doable as I won’t be doing a tonne of the problems as that’ll come with the course next year.

But as you can see I have little time to fit in a full book about SR, I want to be able to enjoy a good SR book and not be rushing to finish it, but I still have Freedman’s University Physics and it does have an introductory chapter on SR with topics covered;
Invariance of physical laws
Relativity of simultaneity
Relativity of time intervals
Relativity of length
The Lorentz Transformation
The Doppler effect for EM waves
Relativistic momentum
Relativistic work and energy
Newtonian mechanics and relativity

So will the chapter in University Physics be enough to cover the SR needed for the Purcell and Morin book?

Thank you in advance.

I think so.

Purcell and Morin is basically an honors intro EM. You should be qualified to start Griffiths, as long as you have calc 3 under your belt

Although not familiar with a student's guide to Maxwell's Equations. It was supplemental reading for a course I took many years ago. The main text we used was Mardsen: Vector Calculus, and I had no issues working through Griffiths. Ie., reading Griffiths for the physics, and not have to worry about the mathematics, and proceed to the problems.
