The Best of Popular Science?

Stront asks: "No doubt like many on Slashdot, I am an avid reader of popular science, and am constantly on the search for good examples of the genre. Now, The Elegant Universe is probably the best on Superstrings; the excellent Genome received a very favourable review on Slashdot; and probably the most anticipated book on Quantum physics is the soon to be released The New Quantum Universe, the follow up to the highly rated The Quantum Universe. Now of the thousands of Popular Science books available, what does Slashdot recommend for the other innumerable sciences such as of relativity, molecular biology, consciousness, astronomy etc?"
