"It doesn't take an Einstein to understand modern physics," says Professor Wolfson at the outset of these 24 lectures on what may be the most important subjects in the universe: relativity and quantum physics. Both have reputations for complexity. But the basic ideas behind them are, in fact, simple and comprehensible by anyone. These dynamic and illuminating lectures begin with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. After that, you'll follow along as Professor Wolfson outlines the logic that led to Einstein's profound theory of special relativity and the simple yet far-reaching insight on which it rests. With that insight in mind, you'll move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time.From there, you'll embark on a dazzling exploration of how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so profound and so at odds with our experience that it nearly defies language.By bringing relativity and quantum mechanics into the same picture, you'll chart the development of fascinating hypotheses about the origin, development, and possible futures of the entire universe, as well as the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. But the goal throughout these lectures remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson.

In a field known for startling ideas, the Many-Worlds Interpretation (MWI) of quantum mechanics may take the prize. It holds that parallel to our own world are a large number of other universes, almost identical to ours but with small variations. Copies of each of us inhabit a myriad of these worlds. But they are not us exactly; they share our past history, but they are different people who have unique futures. Although these realms are invisible and can’t communicate with each other, prominent physicists are convinced they must exist.

A little over a century ago, a young Albert Einstein presented his general theory of relativity to the world and utterly transformed our understanding of the universe. His theory changed the way we think about space and time, revealed how our universe has been expanding from a hot, dense state called the big bang and predicted black holes. Where the Universe Came From is a 13.8 billiion-year journey through the cosmos.

Our understanding of nature's deepest reality has changed radically, but almost without our noticing, over the past 25 years. Transcending the clash of older ideas about matter and space, acclaimed physicist Frank Wilczek explains a remarkable new discovery: matter is built from almost weightless units, and pure energy is the ultimate source of mass. He calls it "The Lightness of Being." Space is no mere container, empty and passive. It is a dynamic Grid, modern ether, and its spontaneous activity creates and destroys particles.

There may never be another era of science like the first half of the twentieth century, when many of the most important physicists ever to live—Marie Curie, Max Planck, Wolfgang Pauli, Niels Bohr, Werner Heisenberg, Ernst Schrödinger, Albert Einstein, and others—came together to uncover the quantum world: a concept so outrageous and shocking, so contrary to traditional physics, that its own founders rebelled against it until the equations held up and fundamentally changed our understanding of reality. Tobias Hürter takes us back to this uniquely momentous and harrowing time.

The story of the men and women who drove the Voyager spacecraft mission, told by a scientist who was there from the beginning. The Voyager spacecraft are our farthest-flung emissaries--11.3 billion miles away from the crew who built and still operate them decades after their launch.

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.

Blood carries life, yet the sight of it makes people faint. It is a life-saver, and can transmit deadly infections. It is medicine, and a commodity dearer than oil. Each of us has nine to 12 pints of it, yet many don’t know their own blood type. For all its ubiqutousness, menstruation is perhaps the single most demonized biological event. In Nine Pints, Rose George takes us from ancient practices of bloodletting to a cutting-edge trauma ward.

Why can your foot move halfway to the brake pedal before you're consciously aware of danger? Why do you notice when your name is mentioned in a conversation that you didn't think you were listening to? Why are people whose name begins with J more likely to marry other people whose name begins with J? Why is it so difficult to keep a secret? Renowned neuroscientist David Eagleman navigates the depths of the subconscious brain to illuminate these surprising mysteries.

This once-in-a-lifetime, 12-session recording captures one of the most unconventional and brilliant writers of this century in conversation, and makes available to Wilson's legion of fans a refreshing insider's view of this enigmatic (and often misunderstood) author. Join Wilson as he discusses such topics as futurist psychology, the paranormal, God, conspiracies real and imagined, James Joyce, guerrilla ontology, plus rare personal reflections on his extraordinary life.

Scientists now understand the history of our universe better than the history of our own planet, but they continue to uncover startling new riddles - the hole in the universe being just one. In this electrifying book, award-winning physicist Paul Davies walks us through the puzzles and paradoxes that have preoccupied cosmologists from ancient Greece to the present day.

Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues that a limited notion of time is holding physics back. It's time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics.

What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilities.

After a few billion years of bearing witness to life on Earth, of watching one hundred billion humans go about their day-to-day lives, of feeling unbelievably lonely, and of hearing its own story told by others, The Milky Way would like a chance to speak for itself. All one hundred billion stars and fifty undecillion tons of gas of it. It all began some thirteen billion years ago, when clouds of gas scattered through the universe's primordial plasma just could not keep their metaphorical hands off each other.

In The Quantum World, leading physicists and New Scientist take you on a journey through quantum theory, its mind-bending properties and the technologies transforming our world. Forget everything you thought you knew about reality. The world is a seriously bizarre place. Things can exist in two places at once and travel backwards and forwards in time. Waves and particles are one and the same, and objects change their behaviour according to whether they are being watched.

In Parallel Worlds, world-renowned physicist and best-selling author Michio Kaku - an author who "has a knack for bringing the most ethereal ideas down to earth" (Wall Street Journal) - takes listeners on a fascinating tour of cosmology, M-theory, and its implications for the fate of the universe.

This audiobook narrated by Juliet Stevenson shares the story of a world-renowned physicist who seeks gravity’s true nature and finds wisdom in embracing its force in her life.

For millennia, people have asked questions about the nature of matter. In the 20th century, this curiosity led to an unprecedented outburst of scientific discovery that changed the course of history. In The Matter of Everything, accelerator physicist Suzie Sheehy introduces us to the people who, through a combination of genius, persistence and luck, staged these groundbreaking experiments.

Adored by children and adults alike, tyrannosaurus is the most famous dinosaur in the world, one that pops up again and again in pop culture, often battling other beasts such as King Kong, triceratops, or velociraptors in Jurassic Park. But despite the hype, tyrannosaurus and the other tyrannosaurs are fascinating animals in their own right and are among the best-studied of all dinosaurs.

At the dawn of the 20th century, humanity was facing global disaster. Mass starvation, long predicted for the fast-growing population, was about to become a reality. A call went out to the worlds scientists to find a solution. This is the story of the two enormously gifted, fatally flawed men who found it: the brilliant, self-important Fritz Haber and the reclusive, alcoholic Carl Bosch. Together they discovered a way to make bread out of air, built city-sized factories, controlled world markets, and saved millions of lives.

Flash crashes. Speed dating. Instant messaging. From the devices we carry to the lives we lead, everything is getting faster, faster. But where did this great acceleration come from? And where will it lead? In this vitally important new audiobook, Robert Colvile explains how the cult of disruption in Silicon Valley, the ceaseless advance of technology and our own fundamental appetite for novelty and convenience have combined to speed up every aspect of daily life.
