This audiobook contains a broad overview of time travel in science fiction, along with a detailed examination of the philosophical implications of time travel. The emphasis of this book is now on the philosophical and on science fiction, rather than on physics, as in the author’s earlier books on the subject. In that spirit there are, for example, no tech notes filled with algebra, integrals, and differential equations, as there are in the first and second editions of Time Machines.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Philosophy of Physics is concerned with the deepest theories of modern physics - notably quantum theory, our theories of space, time and symmetry, and thermal physics - and their strange, even bizarre conceptual implications. A deeper understanding of these theories helps both physics, through pointing the way to new theories and new applications, and philosophy, through seeing how our worldview has to change in the light of what we learn from 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.

From atomic structures to theories about magnetic forces, scientific progress has given us a good grasp on the properties of many different materials. However, science cannot tell us how to measure the temperature of steel just by looking at it, or how to sculpt stone into all kinds of shapes, or what it feels like to blow up a balloon of glass. Handmade is the story of materials through making and doing. Author and material scientist Anna Ploszajski journeys into the domain of makers and craftspeople to comprehend how the most popular materials really work.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution.

Are you puzzled by pulsars? Baffled by black holes? Bewildered by the big bang? If so, here are succinct, crystal-clear answers to more than 100 of the most significant questions about the essential nature of the universe - questions that have fired the imagination since the beginning of history. Over the course of this fantastic voyage, the origins, the discoveries, and the stunning achievements of astronomy will unfold before your eyes

We are unprepared for the greatest discovery of modern science. Scientists are confident that there is alien life across the universe yet we have not moved beyond our perception of 'aliens' as Hollywood stereotypes. The time has come to abandon our fixation on alien monsters and place our expectations on solid scientific footing. Using his own expert understanding of life on earth and Darwin's theory of evolution - which applies throughout the universe - Cambridge zoologist Dr Arik Kershenbaum explains what alien life must be like.

These 24 lectures present a wide-ranging intellectual exploration of this iconic scientist, genius, and champion of social justice. More than just a biography of Einstein's life, Albert Einstein provides you with an inside look at how this brilliant thinker arrived at his various revolutionary breakthroughs.

Einstein's steadfast refusal to accept certain aspects of quantum theory was rooted in his insistence that physics has to be about reality. Accordingly, he once derided as spooky action at a distance the notion that two elementary particles far removed from each other could nonetheless influence each others propertiesa hypothetical phenomenon his fellow theorist Erwin Schrdinger termed quantum entanglement.

At once elegant and riveting, Sync tells the story of the dawn of a new science. Steven Strogatz, a leading mathematician in the fields of chaos and complexity theory, explains how enormous systems can synchronize themselves, from the electrons in a superconductor to the pacemaker cells in our hearts. He shows that although these phenomena might seem unrelated on the surface, at a deeper level there is a connection, forged by the unifying power of mathematics.

Human history has seen many surprising and profound turning points. The ways that humans learned to use raw materials to create activity and resources set the stage for the most compelling and life-altering phase of the modern era, the Industrial Revolution. Born during this time on different continents but connected by similar interests, two men indelibly marked their generation and those that followed with their genius and foresight. This audiobook covers the war of currents and the individual lives of Tesla and Edison.

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.

As Carl Sagan did for astronomy and Brian Green did for cosmology, Walter Lewin takes listeners on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. "I introduce people to their own world," writes Lewin, "the world they live in and are familiar with but don't approach like a physicist - yet."

We all make mistakes. Nobody’s perfect. Not even some of the greatest geniuses in history, as Mario Livio tells us in this marvelous story of scientific error and breakthrough. Charles Darwin, William Thomson (Lord Kelvin), Linus Pauling, Fred Hoyle, and Albert Einstein were all brilliant scientists. Each made groundbreaking contributions to his field - but each also stumbled badly. These five scientists expanded our knowledge of life on Earth, the evolution of the Earth itself, and the evolution of the universe, despite and because of their errors. As Mario Livio luminously explains, the scientific process advances through error.

Best-selling author, superstar physicist, and cofounder of the World Science Festival Brian Greene (The Elegant Universe, The Fabric of the Cosmos) and an ensemble cast led by award-winning actor Paul Rudd (Ant-Man) perform this dramatic story tracing Albert Einstein's discovery of the general theory of relativity.

New York Times best-selling author Deepak Chopra joins forces with leading physicist Menas Kafatos to explore some of the most important and baffling questions about our place in the world.

Most of us are clueless when it comes to the physics that makes our modern world so convenient. What's the simple science behind motion sensors, touch screens, and toasters? How do we glide through tolls using an E-ZPass or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted.

Would you like to know how the universe works? Scientists have been asking that question for a long time and have found that many of the answers can be found in the study of particle physics, the field that focuses on those impossibly tiny particles with unbelievably strange names - the hadrons and leptons, baryons and mesons, muons and gluons - so mystifying to the rest of us.

Mystics and sages have long maintained that there exists an interconnecting cosmic field at the roots of reality that conserves and conveys information, a field known as the Akashic record. Recent discoveries in vacuum physics show that this Akashic field is real and has its equivalent in science's zero-point field that underlies space itself. This field consists of a subtle sea of fluctuating energies from which all things arise: atoms and galaxies, stars and planets, living beings, and even consciousness.
