In How the Laser Happened, Nobel laureate Charles Townes provides a highly personal look at some of the leading events in 20th-century physics. This lively memoir, packed with firsthand accounts and historical anecdotes, is an invaluable resource for anyone interested in the history of science and an inspiring example for students considering scientific careers.

Sixty-six million years ago an asteroid as large as Mt. Everest hit what is now the Yucatan Peninsula at a speed ten times faster than the fastest rifle bullet. Debris from the impact blew into space, re-entered the atmosphere as a swarm of shooting stars that burned the global forests and grasslands, leaving behind a thin global layer containing rock from the asteroid and from Mexico, and smoke from the fires. This layer marks one of the greatest extinctions in Earth history including not just dinosaurs, but also fish, plankton, ammonites, and plants making up about 75% of the known species.

Atomic weaponry is widely understood as a story of American scientific achievement—but scientists working in Britain played a vital role in its development. Including Nobel Prize winners and Jewish refugees from Nazi Germany, these scientists have long since been forgotten. But without their expertise, Robert Oppenheimer's research at Los Alamos would never have succeeded. Gareth Williams unearths the true story of the top-secret British atomic program, codenamed "Tube Alloys," established in 1940.

Are the physical laws of our universe finely tuned, such that life can exist? What does this imply about how our universe formed? Questions like these are examined in Nature's Balancing Act, presented for a wide audience.

The Superluminal Universe reveals, for the first time in English, the incredible insights of French quantum physicist Professor Regis Dutheil. Thanks to the development of particle accelerators, physicists are now able to propel particles (tachyons) at a speed close to that of light (300,000 km per second). At these extreme speeds, the laws that govern our universe no longer apply. Professor Dutheil's work has shown that the theory of relativity is not incompatible with that of tachyons, provided that we allow for the possibility of a double reality.

When Neil Armstrong first set foot in the lunar dust, the Earth held its breath. That one small step forever changed our view of what was possible, sparking a dramatic expansion of humankind's cosmic awareness. When we gain a new perspective, a transformation begins, profoundly altering the understanding of the world our human experience had previously granted us.

David J. Helfand reconstructs the history of the universe—back to its first microsecond 13.8 billion years ago—with the help of atoms. He shows how, by using detectors and reactors, microscopes and telescopes, we can decode the tales these infinitesimal particles tell.

Earth stands at a tipping point. As we fail to curtail emissions fast enough, our planet stares down a cascade of imminent, catastrophic, and irreversible disaster triggered by climate change. Yet a potent technology already exists to buy us more time: solar geoengineering. Through methods such as atmospheric aerosols, human-generated cirrus clouds, and solar sails, we humans can—at least in the short term—slow the Earth's warming. Should we?
