The publication of Darwin’s The Origin of Species in 1859marked a dramatic turning point in scientific thought. The volumehad taken Darwin more than twenty years to publish, in part becausehe envisioned the storm of controversy it was certain to unleash.Indeed, selling out its first edition on its first day, The Originof Species revolutionized science, philosophy, and theology. Darwin’s reasoned, documented arguments carefully advance histheory of natural selection and his assertion that species were notcreated all at once by a divine hand but started with a few simpleforms that mutated and adapted over time. Whether commenting on hisown poor health, discussing his experiments to test instinct inbees, or relating a conversation about a South American burrowingrodent, Darwin’s monumental achievement is surprisingly personaland delightfully readable. Its profound ideas remain controversialeven today, making it the most influential book in the naturalsciences ever written—an important work n

It's hard to talk about The Origin of Species without making statements that seem overwrought and fulsome. But it's true: this is indeed one of the most important and influential books ever written, and it is one of the very few groundbreaking works of science that is truly readable. To a certain extent it suffers from the Hamlet problem--it's full of clichés! Or what are now clichés, but which Darwin was the first to pen. Natural selection, variation, the struggle for existence, survival of the fittest: it's all in here. Darwin's friend and "bulldog" T.H. Huxley said upon reading the Origin, "How extremely stupid of me not to have thought of that." Alfred Russel Wallace had thought of the same theory of evolution Darwin did, but it was Darwin who gathered the mass of supporting evidence--on domestic animals and plants, on variability, on sexual selection, on dispersal--that swept most scientists before it. It's hardly necessary to mention that the book is still controversial: Darwin's remark in

Dr. Carl Sagan takes us on a great reading adventure, offeringhis vivid and startling insight into the brain of man and beast,the origin of human intelligence, the function of our most hauntinglegends--and their amazing links to recent discoveries. "A history of the human brain from the big bang, fifteen billionyears ago, to the day before yesterday...It's a delight." THE NEW YORK TIMES

A good case can be made for Isaac Newton being the finest mindhumanity has yet produced. His theory of gravity offered hiscontemporaries their first glimpse of how the universe actuallyworks, and his mathematics enabled later generations to walk on themoon. Today, we know that gravity keeps our feet on the ground, buthow many of us know how Newton's greatest discovery really works?In Newton Gravity, Paul Strathern encapsulates several ofNewton's more mind-expanding discoveries, explaining in livelyprose their cultural context as well as Newton's early obsessionwith science (bordering on dementia) that made his revolutionaryvision possible. Just a few of the big ideas covered hereare: Newton's discovery of calculus at age twenty-three Why gravity, one of the greatest human insights of all time, wasin fact a hunch and how it actually works Why it took Newton twenty years after his discovery to reveal tothe world the secret of gravity and planetary motion Ideal for the intelligen

We may know that Einstein was the epitome of genius, but howmany of us know what his theory really means, and what itsrealistic implications are? Einstein and Relativity presents adistillation of Einstein's life and work within their historicaland scientific contexts; and offers a truly accessible explanationof the concept that shaped the twentieth century. Just a few of thebig ideas covered here are Einstein's discovery that light is botha particle and a wave; how Einstein proved the existence ofmolecules; why there is no such thing as real time; and howEinstein's brilliance led to his worst nightmare - the atombomb.

Carl Sagan, writer and scientist, returns from the frontier totell us about how the world works. In his delightfullydown-to-earth style, he explores and explains a mind-bogglingfuture of intelligent robots, extraterrestrial life and itsconsquences, and other provocative, fascinating quandries of thefuture that we want to see today.
