Cutting-edge astrophysics that builds on Einstein's theories to find the unseen matter that fills the Universe.Dark energy. Dark matter. These strange and invisible substances don't just sound mysterious: their unexpected appearance in the cosmic census is upending long-held notions about the nature of the Universe. Astronomers have long known that the Universe is expanding, but everything they could see indicated that gravity should be slowing this spread. Instead, it appears that...

From one of our most acclaimed and original colonial historians, a groundbreaking book tracing the critical "long year" of 1774 and the revolutionary change that took place from the Boston Tea Party and the First Continental Congress to the Battles of Lexington and Concord.A WALL STREET JOURNAL BEST BOOK OF THE YEARIn this masterly work of history, the culmination of more than four decades of research and thought, Mary Beth Norton ...

From the best-selling author of The Seven Daughters of Eve, an eye-opening work no dog lover or ancestry aficionado should be without.How did wolves evolve into dogs? When did this happen, and what role did humans play? Oxford geneticist Bryan Sykes used the full array of modern technology to explore the canine genetic journey when our ancestors first learned to hunt together with wolves. In the process, he discovered that only a handful of genes have crea...

From the big bang to black holes, this fast-paced illustrated tour of time and space for the astro-curious unlocks the science of the stars to reveal fascinating theories, surprising discoveries, and ongoing mysteries in modern astronomy and astrophysics.Before the big bang, time, space, and matter didn't exist. In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theo...

A theoretical astrophysicist explores the ideas that transformed our knowledge of the universe over the past century.The cosmos, once understood as a stagnant place, filled with the ordinary, is now a universe that is expanding at an accelerating pace, propelled by dark energy and structured by dark matter. Priyamvada Natarajan, our guide to these ideas, is someone at the forefront of the research—an astrophysicist who literally creates maps of in...

The award-winning science writer "packs a lot of learning into a deceptively light and enjoyable read" exploring the contentious history of the black hole ( New Scientist).For more than half a century, physicists and astronomers engaged in heated dispute over the possibility of black holes in the universe. The strange notion of a space-time abyss from which not even light escapes seemed to confound all logic. Now Marcia Bartusiak, author of Einstein's U...

In 2000, Martin Bojowald, then a twenty-seven-year-old post-doc at Pennsylvania State University, used a relatively new theory called loop quantum gravity—a cunning combination of Einstein’s theory of gravity with quantum mechanics—to create a simple model of the universe. Loop quantum cosmology was born, and with it, a theory that managed to do something even Einstein’s general theory of relativity had failed to do—illuminate the very birth of the universe.Ever since, loop quantum...

On July 4, 2012, physicists at the Large Hadron Collider in Geneva madehistory when they discovered an entirely new type of subatomic particle that many scientists believe is the Higgs boson. For forty years, physicists searched for this capstone to the Standard Model of particle physics—the theory that describes both the most elementary components that are known in matter and the forces through which they interact. This particle points to the Higgs field, which provides the key to underst...

“A great read… Goldberg is an excellent guide.”—Mario Livio, bestselling author of The Golden RatioPhysicist Dave Goldberg speeds across space, time and everything in between showing that our elegant universe—from the Higgs boson to antimatter to the most massive group of galaxies—is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come.Why is the sky dark at night? If there is anti-matt...

Winner of the prestigious 2013 Royal Society Winton Prize for Science Books“A modern voyage of discovery.” —Frank Wilczek, Nobel Laureate, author of The Lightness of BeingThe Higgs boson is one of our era’s most fascinating scientific frontiers and the key to understanding why mass exists. The most recent book on the subject, The God Particle, was a bestseller. Now, Caltech physicist Sean Carroll documents the doorway that...

From the most celebrated heir to Darwin comes a groundbreaking book on evolution, the summa work of Edward O. Wilson's legendary career.Where did we come from? What are we? Where are we going? In a generational work of clarity and passion, one of our greatest living scientists directly addresses these three fundamental questions of religion, philosophy, and science while “overturning the famous theory that evolution naturally encourages creatures to put family first” (Discover

"It would be hard to imagine a better guide to this difficult subject." -- Scientific AmericanIn Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanie...
