Book Meme

Here are the rules:

1. Grab the nearest book.
2. Open the book to page 123.
3. Find the fifth sentence.
4. Post the text of the next 3 sentences on your blog along with these instructions.
5. Don’t you dare dig for that “cool” or “intellectual” book in your closet! I know you were thinking about it! Just pick up whatever is closest.

Here’s mine:

The transformation of components of the second rank η^μν transform by

η’^αβ = Λ^α_ν Λ^β_μ η^μν

by comparison with Eq. (4.26), η’^αβ = η^αβ. Thus η^αβ has the same components in all frames, as we have assumed.

From Radiative Processes in Astrophysics by George B. Rybicki and Alan P. Lightman. No lie — that’s the book I have out on my desk at work. Maybe I’ll try at home tonight, and see what’s lying around there.
