In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

The second half of the 20th century witnessed a scientific gold rush as physicists raced to chart the inner workings of the atom. The stakes were high, the questions were big, and there were Nobel Prizes and everlasting glory to be won. Many mysteries of the atom came unraveled, but one remained intractable-what Frank Close calls the "Infinity Puzzle."

Not only can we not currently explain the origin of the universe, it is questionable we will ever be able to explain it. The notion that there are universes within particles, or that particles are conscious, is ascientific, as is the hypothesis that our universe is a computer simulation. On the other hand, the idea that the universe itself is conscious is difficult to rule out entirely.

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.

Millions of people visit xkcd.com each week to read Randall Munroe's iconic webcomic. His stick-figure drawings about science, technology, language, and love have a large and passionate following. Fans of xkcd ask Munroe a lot of strange questions. What if you tried to hit a baseball pitched at 90 percent of the speed of light? How fast can you hit a speed bump while driving and live? If there were a robot apocalypse, how long would humanity last?

In The Equations of Life, biologist Charles S. Cockell makes the forceful argument that the laws of physics narrowly constrain how life can evolve, making evolution's outcomes predictable. If we were to find something very much like a lady bug eating something very much like an aphid on a distant planet, we shouldn't be surprised. The forms of life are guided by a limited set of rules, and, as a result, there is a narrow set of solutions to the challenges of existence.

Gravity controls everything from the falling of an apple to the rising of ocean’s tides to the motions of the heavens above. If you’ve ever wondered how this most puzzling force works across our entire universe, you will be delighted by this 24-part course that is accessible to any curious person, regardless of your science education. No other product on the market presents the subject of gravity in as much detail as this course, which will follow the past 400 years of research and experimentation in the field.

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

From the best-selling author of the essential new 2019 book on animal agriculture and climate crisis: We are the Weather. Discover Jonathan Safran Foer's eye-opening and life-changing account of the meat we eat. Eating Animals is the most original and urgent book on the subject of food written this century. It will change the way you think and change the way you eat. For good. Whether you're flirting with veganuary, trying to cut back on animal consumption, or a lifelong meat eater, you need to listen to this book.

What we send out into the universe comes back to us magnified. Although the power of intention - the energy of positive thoughts - is widely accepted as an influential force in transforming lives, the exponential power of group intention has never been explored - until now. In The Power of Eight, Lynne McTaggart, an expert on the science of spirituality, reveals her remarkable findings from 10 years of experiments about how group intention can heal our lives - and change the world for the better.

There are approximately 25,000 "city killer" asteroids in near-Earth orbit—and most are yet to be found. Small enough to evade detection, they are capable of large-scale destruction, and represent our greatest cosmic threat. But in September 2022, against all odds, NASA's Double Asteroid Redirection Test (DART) mission deliberately crashed a spacecraft into a carefully selected city killer, altering the asteroid's orbit. In How to Kill an Asteroid, award-winning science journalist Robin George Andrews reveals the development of the technology that made it possible

Inesperado best seller en Italia, con traducciones a más de veinte idiomas, Siete breves lecciones de física se ha convertido en un éxito bien sencillo de explicar por algo muy difícil de conseguir: con pasión, fluidez y una encomiable voluntad de presentar de un modo diáfano temas complejos, Carlo Rovelli, científico de estirpe humanista, nos propone un breve pero muy completo recorrido por los hitos de la física de los últimos cien años en siete lecciones magistrales.

‘It didn’t matter that they were now three miles beyond their target site, that communications were dropping out and that they were running low on fuel. All that mattered to Neil as he searched for a safe spot to land was that boulders littered the surface below. “Thirty seconds,” called mission control. In truth, the flight controllers were now no more than spectators, just like everybody else. No more needed to be said. It was down to Armstrong

Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves - or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a common sense explanation of what is going on.

In this groundbreaking classic, investigative journalist Lynne McTaggart reveals a radical new paradigm - that the human mind and body are not separate from their environment but a packet of pulsating power constantly interacting with this vast energy sea, and that consciousness may be central in shaping our world. The Field is a highly listenable scientific detective story presenting a stunning picture of an interconnected universe and a new scientific theory that makes sense of supernatural phenomena.

In the summer of 1921, Philo T. Farnsworth was not all that different from any other farmer's son in rural Idaho, until he came up with an idea that would change the world–and thrust him into a titanic struggle with one of the most monolithic monopolies in the world. Farnsworth's story of divine inspiration facing off against corporate avarice is a compelling–though seldom told–saga from the 20th century that is still relevant in the 21st.

'Trinity' was the codename for the test explosion of the atomic bomb in New Mexico on 16 July 1945. This exceptional book - Trinity - tells the story of the bomb's metaphorical father, Rudolf Peierls; his intellectual son, the atomic spy, Klaus Fuchs; and the ghosts of the security services in Britain, the USA and USSR.

Welcome to the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions - in health care, transport, finance, security, what we watch, where we go, even whom we send to prison. So how much should we rely on them? What kind of future do we want? Hannah Fry takes us on a tour of the good, the bad and the downright ugly of the algorithms that surround us.

Time moves forward, not backward---everyone knows you can't unscramble an egg. In the hands of one of today's hottest young physicists, that simple fact of breakfast becomes a doorway to understanding the Big Bang, the universe, and other universes, too. In From Eternity to Here, Sean Carroll argues that the arrow of time, pointing resolutely from the past to the future, owes its existence to conditions before the Big Bang itself---a period of modern cosmology of which Einstein never dreamed.

In 1978, the first group of space shuttle astronauts was introduced to the world - 29 men and six women who would carry NASA through the most tumultuous years of the space shuttle program. Among them was USAF Colonel Mike Mullane, who, in his memoir Riding Rockets, strips the heroic veneer from the astronaut corps and paints them as they are - human.
