Humanity's first reusable spacecraft and the most complex machine ever built, NASA's space shuttle debuted with great promise and as a dependable source of wonder and national pride. But with the Challenger catastrophe in 1986, the whole space shuttle program came into question, as did NASA itself, so long an institution that was seemingly above reproach. Wheels Stop tells the stirring story of how, after the Challenger disaster, the space shuttle not only recovered but went on to perform its greatest missions.

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think. These magnificent 24 lectures are devoted to busting myths, clearing up confusion, and giving you scientific epiphanies that could change how you think about your everyday world.

Les Johnson takes you on a thrilling tour of the physics and technologies that may enable us to reach the stars. He discusses the latest exoplanet discoveries, promising interstellar missions on the not-so-distant horizon, and exciting new developments in space propulsion, power, robotics, communications, and more. But interstellar travel will not be easy, and it is not for the faint of heart. Johnson describes the harsh and forbidding expanse of space that awaits us, and he addresses the daunting challenges that we need to overcome in order to realize tomorrow's possibilities.

As end-of-the-world scenarios go, an apocalyptic collision with an asteroid or comet is the new kid on the block, gaining respectability only in the last decade of the 20th century with the realisation that the dinosaurs had been wiped out by just such an impact. Now the science community is making up for lost time, with worldwide efforts to track the thousands of potentially hazardous near-Earth objects and plans for high-tech hardware that could deflect an incoming object from a collision course - a procedure depicted in several Hollywood movies.

Fight Like a Physicist provides an in-depth, sometimes whimsical look into the physics behind martial arts for sport and self-defense. Whether you are an experienced martial artist or a curious enthusiast, this book can give you an "unfair advantage" by unraveling the complex science of effective fighting techniques and examining the core principles that make them work.

One of the biggest questions Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. But his famous theory on the Big Bang ran into a crisis when the equations predicted a multiverse - countless different universes, most of which were too bizarre to support life. Holed away in the physics department at Cambridge, Stephen Hawking and his collaborator Thomas Hertog worked for twenty years on a new theory of the cosmos.

In The Allure of the Multiverse, physicist Paul Halpern tells the epic story of how science became besotted with the multiverse, and the controversies that ensued. The questions that brought scientists to this point are big and deep: Is reality such that anything can happen, must happen? How does quantum mechanics "choose" the outcomes of its apparently random processes? And why is the universe habitable? Each question quickly leads to the multiverse.

Throughout history, thinkers from mathematicians to theologians have pondered the mysterious relationship between numbers and the nature of reality. In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887.... This curious mathematical relationship, widely known as "The Golden Ratio", was discovered by Euclid more than 2,000 years ago. Since then it has shown a propensity to appear in the most astonishing variety of places.

Physics informs our understanding of how the world works - but more than that, key breakthroughs in physics have transformed everyday life. We journey back to 10 separate days in history to understand how particular breakthroughs were achieved, meet the individuals responsible and see how each breakthrough has influenced our lives.

When neuroscientist Susan Barry was 50 years old, she took an unforgettable trip to Manhattan. As she emerged from the dim light of the subway into the sunshine, she saw a view of the city that she had witnessed many times in the past but now saw in an astonishingly new way. Skyscrapers on street corners appeared to loom out toward her like the bows of giant ships. Tree branches projected upward and outward, enclosing and commanding palpable volumes of space.

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.

Why does your weather app say “there’s a 10 percent chance of rain” instead of “it will be sunny”? In large part, this is due to the insight of award-winning physicist Tim Palmer, who pioneered the introduction of uncertainty into weather and climate prediction. Now, he wants to apply it to how we study everything else.

You never knew that theoretical physics could be so simple! In this exciting and significant audiobook, Andrew Thomas reveals how all unifications in physics have been based on incredibly simple ideas.

Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public goods. His point of view is rationalist, realist, reductionist, and devoutly secularist.

Stripping away the known and seeing reality for what it is, rather than for what our thoughts represent it to be, provides the theme for this compelling conversation. The late theoretical physicist David Bohm addresses the nature of thought and thinking, and how our conditioned minds become subordinate to the way we think.

Free Creations of the Human Mind: The Worlds of Albert Einstein presents a concise and nuanced account of Einstein's life and work embedded in his intellectual and social contexts. His life is interconnected with so many of the important political and intellectual movements of his era—Zionism, pacifism, Nazism, nuclear weapons, philosophy, civil rights, McCarthyism, the League of Nations, and substantial discoveries in epochal theories of special relativity and quantum theory.

As a subject, it has perplexed and fascinated generations of scientists, historians and more, and continues to spark the most intriguing questions being asked in science today. Can time be stopped? Is time travel possible? Does time even exist? In these 10 bite-sized essays, Colin Stuart delves into these big questions and uncovers the most awe-inspiring and revealing things we should all know about time.

One of the great mysteries of science is that its fundamental laws are written in the language of mathematics. Graham Farmelo's thrilling new book shows how modern maths has helped physicists to rethink gravity, space, and time. The Universe Speaks in Numbers takes us on an adventure from the Enlightenment to the present with a vibrant cast of characters, illuminating the most exciting and controversial developments in contemporary thought.

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.
