What is matter made of? Scientists have been trying to answer this question for thousands of years. The concept of the atom—the tiniest fragment of a substance that still retains the characteristics of that substance—goes back to the Greek philosopher Leucippus, who lived in about 450 b.c. In the mid-1600s, Robert Boyle provided experimental evidence that atoms did, indeed, exist. And in 1897, British physicist Joseph John Thomson discovered the first subatomic particle: the electron. Yet even the tiny components of the atom—protons, electrons, and neutrons—are not the smallest things in the universe. Subatomic particles are made up of still tinier objects called quarks and leptons. This book tells the story of how scientists unlocked the secrets of the atom and revolutionized the way we look at the world around us.

In the 1880s, science witnessed a major shift: Charles Darwin proposed his theory of evolution. People dug up the first dinosaur fossils. And the field of paleontology—the study of ancient plants and animals—emerged. Othniel Charles Marsh and Edward Drinker Cope became enthralled with these new ideas, discoveries, and developments. Both were determined to become world-famous paleontologists. When they met in 1863, they started off as friends. But within a few years, competition drove the men apart. Each fought bitterly to discover more fossils, name more species, and publish more papers than the other. In their haste to outdo each other, they both produced some shoddy work. The resulting confusion took many years to discover and correct, and their toxic relationship crippled the field of paleontology for decades afterward. However, the competition also produced a wealth of fossils. These laid a firm foundation for the field of paleontology and supported Darwin''s theory of evolution. Marsh''s and Cope''s discoveries generated keen public interest in prehistoric life and rich data for future generations of paleontologists. This book explores the great rivalry between Marsh and Cope, showing how it brought out the best and the worst in them—while bringing humankind a brand-new view of life on Earth.
