I don’t normally get involved with these things.  But I figured, “what the heck”.  So, first the instructions:

• Grab the nearest book
• Open it to page 56
• Find the 5th sentence
• Post the text of that sentence in your blog with these instructions.

And now for the results:

“They were working on a suggestion, made by George Gamow (once a student of Alexander Friedmann), that the early universe should have been very hot and dense, glowing white hot.”

And that is page 56, the 5th full sentence of the page, from “The Illustrated A BRIEF HISTORY OF TIME”, by Stephen Hawking.
