Damien has provided and yet significantly undersold the commentary by Steven Weinberg on the structure of the universe and the relationship between Science & Religion.
This commentary, by a Nobel prize winner, should be required reading in (perhaps) Junior High School, by everyone. It seems it would be much more relevant to read a commentary about the nature of the universe and Sci-Rel perspectives than life in the Midwest ~150 years ago (Tom Sawyer/Huck Finn).
[Not that I'm dumping on Mark Twain mind you, but the question of "relevancy" is worth consideration.]
As a personal commentary, I was in school when Glashow & Weinberg were working out the electroweak theories that they (&Salam) won the Nobel price for in '79. While I don't recall Weinberg teaching any of my classes, I'm fairly sure that Glashow taught several. These men (IMO) are "gods". They take the universe apart and explain it to those who would otherwise be incapable of understanding it. When the speak we should listen.
