SUMMARY

The discussion centers on a potential misprint in equation (2) on page 277 of Landau and Lifshitz's "The Classical Theory of Fields," specifically regarding the term Dα. Users compare different editions of the book, noting discrepancies between the Third Revised English Edition (1971) and the Fourth Revised English Edition (1975). The Fourth Edition does not contain equation (2) as referenced, leading to confusion. Participants emphasize the importance of providing accurate references and suggest posting scans or LaTeX representations of the equations for clarity.

PREREQUISITES
  • Familiarity with Landau and Lifshitz's "The Classical Theory of Fields"
  • Understanding of tensor notation and equations in theoretical physics
  • Knowledge of LaTeX for formatting equations
  • Awareness of copyright considerations in academic discussions
NEXT STEPS
  • Review the Fourth Revised English Edition (1975) of "The Classical Theory of Fields" for accurate equations
  • Learn how to format equations in LaTeX for clearer communication in forums
  • Research copyright laws regarding fair use in academic contexts
  • Explore the differences between various editions of Landau and Lifshitz's works
USEFUL FOR

The discussion is beneficial for physics students, educators, and researchers who are studying theoretical physics and require clarity on specific equations in Landau and Lifshitz's texts.

I go on reading the Landau & Lifshitz Vol 2.
I guess that Dα in the equation (2) on p. 277 is a misprint.

Error?: Dα = Eα/√h + gβ Hαβ ⋅⋅⋅ (2)
Correct: ???

Would you correct a misprint ?

Eq. (2) on page 277 of my copy of Landau and Lifshitz Vol. 2 The Classical Theory of Fields, Third Revised English Edition 1971 looks nothing like that. Can you post a scan of the equation from your copy?

I'm reading the book whose version is Fourth Revised English Edition 1980.
 
Instead of the page, you could give the name of the chapter ans section.

I think this is the fourth edition:
Thanks for the link to the 4th edition of The Classical Theory of Fields (first published in 1975, not 1980). The only equations on pg. 277 in that edition are numbered (95.9) & (95.10). There is no eq. (2).
@shin1980 please post your equation of concern here in proper LaTeX or else post a scan of that equation from the book.

In the 4th edition (1975), the relevant page is 257, not 277.

I believe I was able to derive the equation for ##D_{\alpha}## in (2) by following the suggestions in the problem. I don't see any misprint or error here.

I get it.
chapter: CHAPTER 10 PARTICLE IN A GRAVITATIONAL FIELD
section: $90. The equations of electrodynamics in the presence of a gravitational field

All right, but I can't post a scan of that equation from the book for a copyright.
In addition, I can't display the LaTeX code for that equation displayed in the forum by right-clicking under Windows on a computer (The cause of the failure is unknown).

So please excuse me for displaying a non-LaTeX code for that equation.

chapter: CHAPTER 10 PARTICLE IN A GRAVITATIONAL FIELD
section: $90. The equations of electrodynamics in the presence of a gravitational field

PROBLEM
Eα = F0α, Bαβ = Fαβ,
Dα = -√g00F0α, Hαβ = √g00Fαβ (1)

Solution:
F0α = g0lgαmFlm, Fαβ = gαlgβmFlm,

Dα = Eα/√h + gβHαβ,
Bαβ = Hαβ/√h + gβEα - gαEβ. (2)

Bα = -1/2√γeαβγBβγ,
Hα = -1/2⋅√γ eαβγHβγ (3)

D = E/√h + H×g, B = H/√h + g×E. (4)

Physics Forums is hosted in the USA, where copyright law allows limited "fair use" of protected materials for, among other reasons, teaching, scholarship and research. Posting a scan here of the equation and surrounding text from the book almost certainly is allowed by fair use.

Thank you for your advise. I post a scan of that equation from the book.
