In 1911, a relatively unknown physicist named Albert Einstein published his preliminary theory of gravity. But it hadn't been tested. To do that, he needed a photograph of starlight as it passed the sun during a total solar eclipse. So began a nearly decade-long quest by seven determined astronomers from observatories in four countries, who traveled the world during five eclipses to capture the elusive sight. Over the years, they faced thunderstorms, the ravages of a world war, lost equipment, and local superstitions.

What would it have been like to be an eyewitness to the Big Bang? In 2014, astronomers wielding BICEP2, the most powerful cosmology telescope ever made, revealed that they'd glimpsed the spark that ignited the Big Bang. Millions around the world tuned in to the announcement broadcast live from Harvard University, immediately igniting rumors of an imminent Nobel Prize. But had these cosmologists truly read the cosmic prologue or, swept up in Nobel dreams, had they been deceived by a galactic mirage?

Instead of “what if the South won the Civil War?” cosmologists ask, “what if the constants that make up the fundamental building blocks of physics were different?” Physicists argue that any slight change to the laws of physics would mean a disruption in the evolution of the universe - and our existence. With the many factors that had to align for us to exist, it can seem like the laws of physics might seem finely tuned to make our existence possible. Instead of a supernatural or divine explanation, this book explores the possibility is that our universe isn’t the only one.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

For more than 50 years, the world's top scientists searched for the "missing" planet Vulcan, whose existence was mandated by Isaac Newton's theories of gravity. Countless hours were spent on the hunt for the elusive orb, and some of the era's most skilled astronomers even claimed to have found it. There was just one problem: It was never there.

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.

Long before space travel was possible, the idea of life beyond Earth transfixed humans. In this fascinating book, astronomer Jon Willis explores the science of astrobiology and the possibility of locating other life in our own galaxy. Describing the most recent discoveries by space exploration missions, including the Kepler space telescope, the Mars Curiosity rover, and the New Horizons probe, Willis asks listeners to imagine - and choose among-five scenarios for finding life.

Perhaps the biggest question Stephen Hawking tried to answer in his extraordinary life was how the universe could have created conditions so perfectly hospitable to life. In order to solve this mystery, Hawking studied the big bang origin of the universe, but his early work ran into a crisis when the math predicted many big bangs producing a multiverse—countless different universes, most of which would be far too bizarre to ​harbor life.

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…

The galaxy, the multiverse, and the history of astronomy are explored in this engaging compilation of cosmological "tales" by multiple award-winning science writer Marcia Bartusiak. In 32 concise and engrossing essays, the author provides a deeper understanding of the nature of the universe and those who strive to uncover its mysteries. Bartusiak shares the back stories for many momentous astronomical discoveries, including the contributions of such pioneers as Beatrice Tinsley and her groundbreaking research in galactic evolution.

"The Universal One" by Walter Russell is an ambitious and comprehensive work that endeavors to blend the realms of science, philosophy, and spirituality into a singular, cohesive theory of the universe.

Einstein’s Shadow follows a team of elite scientists on a historic mission to take the first picture of a black hole, putting Einstein’s theory of relativity to its ultimate test and helping to answer our deepest questions about space, time, the origins of the universe, and the nature of reality.

One of the greatest physicists of the twentieth century, Richard Feynman possessed an unquenchable thirst for adventure and an unparalleled ability to tell the stories of his life. "What Do You Care What Other People Think?" is Feynman's last literary legacy, prepared with his friend and fellow drummer, Ralph Leighton.

As a child, Sarafina El-Badry Nance spent nearly every evening with her father gazing up at the flickering stars and pondering what secrets the night sky held. The daughter of an American father and Egyptian mother who both pushed her toward academic excellence, Sarafina dreamed of becoming an astronomer and untangling the mysteries of the stars overhead. But it wasn’t long before she was told, both explicitly and implicitly, that girls just weren’t cut out for math and science.

In The Universe in a Box, cosmologist Andrew Pontzen explains how physicists model the universe’s most exotic phenomena, from black holes and colliding galaxies to dark matter and quantum entanglement, enabling them to study the evolution of virtual worlds and to shed new light on our reality.

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.

Every NASCAR fan—at one time or another—asks the same question: Why isn't my favorite driver winning? This is your chance to discover how much more there is to NASCAR than "Go fast, turn left, and don't crash." In this fast-paced investigation into the adrenaline-pumping world of NASCAR, a physicist with a passion uncovers what happens when the rubber hits the road and 800-horsepower vehicles compete at 190 miles per hour only inches from one another.

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

In Powers of the Universe, cosmologist Brian Swimme identifies 11 powers that are present everywhere and throughout time in the universe. By examining these powers, Dr. Swimme reveals the characteristics of the universe that exist in the subatomic particles, the elements, the galaxies, stars, supernovas, planets, continents, oceans, life, and humans.

All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.
