Your body is teeming with tens of trillions of microbes. It's an entire world, a colony full of life. In other words, you contain multitudes. These microscopic companions sculpt our organs, protect us from diseases, guide our behaviour and bombard us with their genes. They also hold the key to understanding all life on earth. In I Contain Multitudes, Ed Yong opens our eyes and invites us to marvel at ourselves and other animals in a new light, less as individuals and more as thriving ecosystems.

At the end of his career, Albert Einstein was pursuing a dream far more ambitious than the theory of relativity. He was trying to find an equation that explained all physical reality - a theory of everything. Experimental physicist and award-winning educator Dr. Don Lincoln takes you on this exciting journey in The Theory of Everything: The Quest to Explain All Reality. Suitable for the intellectually curious at all levels and assuming no background beyond basic high-school math, these 24 half-hour lectures cover recent developments at the forefront of particle physics and cosmology.

In 1965, the great American physicist Richard Feynman famously proclaimed, "I think I can safely say that nobody understands Quantum Mechanics." Is there any wonder why? Particles that pop in and out of existence... Spooky action at a distance that travels faster than light... Infinite universes and branching realities? In this book, we will break through the confusion and reveal to you the most important ideas of Quantum Physics, told through the amazing true story of just 4 bizarre discoveries.

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?

From the creator of the wildly popular xkcd, What If? gives hilarious and informative answers to important questions you probably never thought to ask. Millions visit xkcd.com each week to read Randall Munroe's iconic webcomic. Fans ask him a lot of strange questions. How fast can you hit a speed bump, driving, and live? When (if ever) did the sun go down on the British Empire? When will Facebook contain more profiles of dead people than living?

The essential guide to radiation: the good, the bad, and the utterly fascinating, explained with unprecedented clarity. Earth, born in a nuclear explosion, is a radioactive planet; without radiation, life would not exist. And while radiation can be dangerous, it is also deeply misunderstood and often mistakenly feared. Now Robert Peter Gale, M.D. - the doctor to whom concerned governments turned in the wake of the Chernobyl and Fukushima - in collaboration with medical writer Eric Lax draws on an exceptional depth of knowledge to correct myths and establish facts.

Have you always been fascinated by quantum physics' spellbinding twirls but been held back by its daunting equations? Are you eager to explore the Quantum universe and unravel its mysteries but dread diving into a sea of complex numbers? Master the mystical world of Quantum Physics in just a few hours. Empower yourself with the knowledge of the microscopic universe, minus the mind-boggling math!

Today, across the universe, at the heart of every galaxy, and dotted throughout, mature black holes are creating chaos. And in a quiet part of the universe, the Swift satellite has picked up evidence of a gruesome death caused by one of these dark powers. High-energy X-ray flares shooting out from deep within the Draco constellation are thought to be the dying cries of a white dwarf star being ripped apart by the intense tides of a supermassive black hole—heating it to millions of degrees as it is shredded at the event horizon.

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.

From the best-selling author of Seven Brief Lessons on Physics comes a new audiobook about the mind-bending nature of the universe. What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries.

The possibility of life elsewhere in the cosmos is one of the most profound subjects that human beings can ponder. Astrophysicist Andrew May gives an expert overview of our current state of knowledge, looking at how life started on Earth, the tell-tale ‘signatures’ it produces and how such signatures might be detected elsewhere in the solar system or on the many ‘exoplanets’ now being discovered by the Kepler and TESS missions.

The field of mind-body medicine is plagued by wild claims that mislead patients and instil false hope. But as scientists in a range of fields uncover solid evidence that our minds influence our bodies quite profoundly, there is now great promise, too. Jo Marchant attempts to use scientific research to find out if alternative medicines work; if our thoughts, beliefs and emotions influence our physical health; and if we can train our brains to heal our bodies.

The National Aeronautics and Space Administration - NASA - was established on July 29, 1958. Ever since that day, NASA has been at the forefront of efforts to explore outer space, resulting in the Apollo missions to the moon, the Skylab space-station, and today's space shuttle. But behind the open face of NASA, there is a much more mysterious world. NASA has been linked to a wealth of high-level cover-ups.

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.

Every living being throughout history, across time and geography, has gazed up at the same moon. From the first prehistoric life that crawled onto land guided by the power of the tides, to the division of time into months and seasons for the first humans, the moon has driven the expansion and development of our world. Our Moon tells the dazzling story of how the Moon has shaped life as we know it, fuelled dramatic change across the globe and could be the key to humanity's future.

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.

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.

Have you ever wondered how your early life shaped you? From beginning to say simple words like 'mama' and learning how to walk around unaided, to the first day of school and forming new friendships, everyone has been a child. The roots of our adult selves go right back to our first experiences. How we think, act and interact is influenced by our early years, yet most people don't know the key findings from the juiciest child development studies that can give us insight into our adult selves.

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.

The cells in our bodies consist of molecules, made up of the same carbon, oxygen, and hydrogen atoms found in air and rocks. But molecules, such as water and sugar, are not alive. So how do our cells - assemblies of otherwise "dead" molecules - come to life, and together constitute a living being? In Life’s Ratchet, physicist Peter M. Hoffmann locates the answer to this age-old question at the nanoscale.
