The Clockwork Universe is the story of a band of men who lived in a world of dirt and disease but pictured a universe that ran like a perfect machine. A meld of history and science, this book is a group portrait of some of the greatest minds who ever lived as they wrestled with natures most sweeping mysteries. The answers they uncovered still hold the key to how we understand the world.

In SPQR, world-renowned classicist Mary Beard narrates the unprecedented rise of a civilization that even 2,000 years later still shapes many of our most fundamental assumptions about power, citizenship, responsibility, political violence, empire, luxury, and beauty.

Predating written language and marching on through human history, the desire for ever-better timekeeping has spurred technological innovation and sparked theories that radically reshaped our understanding of the universe and our place in it.

In Your Brain Is a Time Machine, brain researcher and best-selling author Dean Buonomano draws on evolutionary biology, physics, and philosophy to present his influential theory of how we tell and perceive time. The human brain, he argues, is a complex system that not only tells time but creates it; it constructs our sense of chronological flow and enables "mental time travel" - simulations of future and past events.

The story of poison is the story of power. For centuries, royal families have feared the gut-roiling, vomit-inducing agony of a little something added to their food or wine by an enemy. To avoid poison, they depended on tasters, unicorn horns, and antidotes tested on condemned prisoners. Servants licked the royal family's spoons, tried on their underpants, and tested their chamber pots. Ironically, royals terrified of poison were unknowingly poisoning themselves daily with their cosmetics, medications, and filthy living conditions.
