The essential guide to radiation: the good, the bad, and the utterly fascinating, explained with unprecedented clarity. Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and...

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

From Aristotle to Einstein, An Incomplete Theory takes us on a riveting journey through time, making pit stops at the lives of many exceptional individuals whose insightful work is the foundation of the physical science we know today. Free from equations, this book unlocks the vault of human knowledge with no assumption of scientific background on the part of the listener. It tells and weaves together the stories behind some of history’s greatest thinkers and scientific discoveries.

The National Aeronautics and Space Administration - NASA - was established on July 29, 1958. Ever since that day, NASA has been at the forefront of efforts to explore outer space, resulting in the Apollo missions to the moon, the Skylab space-station, and today's space shuttle. But behind the open face of NASA, there is a much more mysterious world. NASA has been linked to a wealth of high-level cover-ups.

Enrico Fermi is unquestionably among the greats of the world's physicists, the most famous Italian scientist since Galileo. Called "the Pope" by his peers, he was regarded as infallible in his instincts and research. His discoveries changed our world; they led to weapons of mass destruction and conversely to life-saving medical interventions. This unassuming man struggled with issues relevant today, such as the threat of nuclear annihilation and the relationship of science to politics.

In this visionary book, Dr. Tim Gregory challenges prevailing narratives around climate change, arguing that the goal of net zero is not simply to replace fossil fuels with renewables, but to power civilization using sources of energy that do not emit carbon dioxide. He unequivocally shows that only one emissions-free energy source can rise to that challenge: nuclear power.

From the speed of light to moving mountains -- and everything in between -- Zoom explores how the universe and its objects move. If you sit as still as you can in a quiet room, you might be able to convince yourself that nothing is moving. But air currents are still wafting around you. Blood...

Have you ever wondered why onions make us cry? Do you believe bananas contain more calories as they ripen and get sweeter? This sequel to the best-selling What Einstein Told His Cook continues Robert L. Wolke's investigations into the science behind our foods.

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.

Since the 1950s, scientists have attempted to harness nuclear fusion—the process that creates the Sun's energy—to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke.

Science and technology are, without a doubt, two forces that will change the way you live your life in the coming months, years, and decades. And in recent decades, these forces have evolved and developed at a lightning-fast pace. Explore the many possibilities of what your future may look like with these 24 lectures: a scientifically accurate and enlightening survey of today's most advanced research in fields such as engineering, biology, chemistry, and theoretical physics.

Quantum theory is the most revolutionary discovery in physics since Newton. This book gives a lucid, exciting, and accessible account of the surprising and counterintuitive ideas that shape our understanding of the sub-atomic world. It does not disguise the problems of interpretation that still remain unsettled 75 years after the initial discoveries. Uncertainty, probabilistic physics, complementarity, the problematic character of measurement, and decoherence are among the many topics discussed.

Guido Tonelli nous plonge dans une véritable odyssée spatio-temporelle, remarquablement documentée et alimentée par les travaux des grands chercheurs à l’origine des avancées majeures en physique théorique.

In the Shadow of the Moon tells the story of the most exciting and challenging years in spaceflight, with two superpowers engaged in a titanic struggle to land one of their own people on the moon. Drawing on interviews with astronauts, cosmonauts, their families, technicians, and scientists, as well as rarely seen Soviet and American government documents, the authors craft a remarkable story of the golden age of spaceflight as both an intimate human experience and a rollicking global adventure.

A breakout best seller in Italy, now available for American listeners for the first time, Genesis: The Story of How Everything Began is a short, humanistic tour of the origins of the universe, earth, and life - drawing on the latest discoveries in physics to explain the seven most significant moments in the creation of the cosmos.

"Celebrates a bold era when voyaging beyond the Earth was deemed crucial to national security and pride." -The Wall Street Journal Restoring the drama, majesty, and sheer improbability of an American triumph, this is award-winning historian Craig Nelson's definitive and thrilling story of man's...

With wonder, wit, and flair - and in record time and space - geophysicist David Bercovici explains how everything came to be everywhere, from the creation of stars and galaxies to the formation of Earth's atmosphere and oceans to the origin of life and human civilization. Bercovici marries humor and legitimate scientific intrigue, rocketing listeners across nearly 14 billion years and making connections between the essential theories that give us our current understanding of topics as varied as particle physics, plate tectonics, and photosynthesis.

Humans from the earliest civilizations were spellbound by the night sky - craning their necks each night, they used the stars to orient themselves in the large, strange world around them. Stargazing is a pursuit that continues to fascinate us: from Copernicus to Carl Sagan, astronomers throughout history have spent their lives trying to answer the biggest questions in the universe. Now, award-winning astronomer Emily Levesque shares the stories of modern-day stargazers.

Drawing intriguing parallels between the present era of quantum physics and past episodes of scientific confusion, Beyond the Quantum tells the story of how pilot-wave theory was discovered and abandoned, revived and reconstructed, and how today it can pave the way to a new and radical physics beyond the quantum.

An illuminating, millennia-spanning history of the impact mathematics has had on the world, and the fascinating people who have mastered its inherent power, from Babylonian tax officials to the Apollo astronauts to the eccentric professor who invented the infrastructure of the online world...
