Sadly, i haven't read many books
I was big time into literature in higschool, but mostly fiction. the college came, and away went my time.
now, i mostly just read on the web. I have several books inline to read though, some fiction some fact, including some of the ones listed above, especially 1984.
But, one book i would reccomend to anyone is "The Life Era" by Eric Chaisson. Truly remarkable book that changed my life. It's quite math and physics heavy, but a good read even if you don't understand all the equations. Which even with a strong math background, 4 years of college, and 3 years of computer programming, i didn't fully grasp. Just pick it up and read it, believe me.
Also, "A Brief History of Time" by Steven Hawkings is excellent, also in the physics realm.
Here are some good quotes from that book:
Also, "Billions and Billions" by Carl Sagan, a book i always THOUGHT was about astronomy, but is actually not entirely, it is a collection of essays on a variety of subjects, including but not limited to the cold war, and abortion. Those are the only chapters i have read, but i'd love to finish it.
