This is an amazing compendium of short sections from other books. It contains pieces by some of the most famous physicists. You are not expected to read it from cover to cover. It is a great book for dipping into and reading a bit here and a bit there. I also like the fact that it contains sections about a more artistic understanding of Science - perhaps a more emotional response. The section of poems contains a couple by Annie Dillard, whose work I love. She is a modern American writer in the Transcedentalist tradition who sees Nature as awe-inspiring.
