SUMMARY

Robert Wald's upcoming textbook, "Advanced Classical Electromagnetism," is set to be released in March 2022 and offers a novel perspective on electromagnetism by emphasizing potentials over field strengths. The first chapter, titled "Electromagnetic Theory without Myths," challenges traditional views, arguing that electromagnetic fields can exist independently of charged matter. The book aims to clarify misconceptions in the field, presenting electromagnetism in a way that avoids historical biases. Key topics include gauge theory and the treatment of electrostatics starting from Poisson's equation rather than Coulomb's law.

PREREQUISITES
  • Understanding of classical electromagnetism principles
  • Familiarity with Maxwell's equations
  • Basic knowledge of gauge theories
  • Experience with mathematical physics and differential equations
NEXT STEPS
  • Explore the implications of gauge invariance in electromagnetism
  • Study the differences between potentials and field strengths in electromagnetic theory
  • Investigate the historical context and evolution of electromagnetism teaching methods
  • Read Robert Wald's previous works on self-force and point particles in electromagnetism
USEFUL FOR

Physicists, graduate students in physics, and educators seeking to deepen their understanding of electromagnetism and its foundational concepts.

Cool! What are your first impressions of the text?
It is clearly a physics text, not a mathematical methods book. My one word description is “Clean”. He knows the path he wants to tread and he does not wander from it. It’s short with 225 pages of text, but it is more than just a set of lecture notes. If you do not know the math he uses, you will need supplementary material. That being said, the math doesn’t look scary. I think I will need to refresh my knowledge of Green’s functions. After thumbing through it, I am still looking forward to reading it.

Mine came about an hour ago. It seems very well formatted and logically presented. My first impression is that for me this is a perfect recapitulation. This means that there is not very much new to me (an old dog) yet I am certain I will learn a lot. Just like Christmas morning. If I find any major warts I will bring them up.

It is literally lecture notes though. I was one of his students when he was making the book
