In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

High above the windswept plains of Kazakhstan, three astronauts on board a Russian Soyuz capsule begin their reentry. A strange shimmer in the atmosphere, a blinding flash of light, and the capsule vanishes in a blink as though it never existed. Daniel Rice is a government science investigator. Marie Kendrick is a NASA operations analyst. Together, they must track down the cause of the most bizarre event in the history of human spaceflight. They draw on scientific strengths as they plunge into the strange world of quantum physics.

Today we are blessed with two extraordinarily successful theories of physics. The first is Albert Einstein's general theory of relativity, which describes the large-scale behavior of matter in a curved spacetime. The second is quantum mechanics. This theory describes the properties and behavior of matter and radiation at their smallest scales.

Everyone knows that Chitzas are masters of spatial compression, routinely exploring distant places across the Milky Way in their wedge-shaped scout ships. But rumors abound of even greater accomplishments. Some say these intrepid explorers have reached beyond the galaxy. When a distress signal is received from deep space, making sense of the emergency becomes a personal matter for Daniel Rice. His wife is onboard that ship.

In Quantum Physics: What Everyone Needs to Know, quantum physicist Michael G. Raymer distills the basic principles of such an abstract field, and addresses the many ways quantum physics is a key factor in today's science and beyond. The book tackles questions as broad as the meaning of quantum entanglement and as specific and timely as why governments worldwide are spending billions of dollars developing quantum technology research. Raymer's list of topics is diverse, and showcases the sheer range of questions and ideas in which quantum physics is involved.

In The Quantum Universe, Brian Cox and Jeff Forshaw approach the world of quantum mechanics in the same way they did in Why Does E=mc2? and make fundamental scientific principles accessible - and fascinating - to everyone.The subatomic realm has a reputation for weirdness, spawning any number of profound misunderstandings, journeys into Eastern mysticism, and woolly pronouncements on the interconnectedness of all things. Cox and Forshaw's contention? There is no need for quantum mechanics to be viewed this way.

Why is gravity the only force that refuses to play by the rules? In this deep dive, we explore the history and current status of the search for a "Theory of Everything"—the holy grail of physics that aims to unify Einstein’s General Relativity with Quantum Mechanics. This series takes you to the frontlines of the battle between the two biggest contenders: String Theory and Loop Quantum Gravity. We explain why the "Graviton" is the most elusive particle in the universe, why gravity is so shockingly weak, and whether we might be wrong about the fundamental nature of reality.

Strange and probabilistic, physics at the smallest scales is driving innovation and research into the nature of reality. In this audiobook, we examine the latest mind-bending studies in quantum mechanics, including theoretical mysteries such as entanglement, real-world applications, innovations in communications and computing, and more.

Three months on a private island. Two men. One million dollars. All I have to do is tame Nash Wilde. It’s been two years since my sister and her boyfriend were killed in a plane crash. The last person I expected to show up on my doorstep was his father, Alistair Wilde. Yet, he came with an offer I’d be an idiot to pass up: be his son’s girlfriend for three months, live with the two of them in a remote house, and the one million dollars is mine.

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?

The discovery of the quantum - the idea, born in the early 1900s in a remote corner of physics, that energy comes in finite packets instead of infinitely divisible quantities - planted a rich set of metaphors in the popular imagination. Quantum imagery and language now bombard us like an endless stream of photons. Phrases such as multiverse, quantum leap, alternate universe, the uncertainty principle, and Schrödinger's cat get reinvented continually in cartoons and movies, coffee mugs and T-shirts, and fiction and philosophy.

Utterly beautiful. Profoundly disconcerting. Quantum theory is quite simply the most successful account of the physical universe ever devised. Its concepts underpin much of the 21st-century technology that we now take for granted. But at the same time it has completely undermined our ability to make sense of the world at its most fundamental level.

The story of the unlikely friendship between the two physicists who fundamentally recast the notion of time and history In 1939, Richard Feynman, a brilliant graduate of MIT, arrived in John Wheeler's Princeton office to report for duty as his teaching assistant. A lifelong friendship and...

On the eve of a top secret space mission, Captain Calli Chase detects a tripped alarm in the tunnels deep below a NASA research center. A NASA pilot, quantum physicist, and cybercrime investigator, Calli knows that a looming blizzard and government shutdown could provide the perfect cover for sabotage, with deadly consequences. As it turns out, the danger is worse than she thought. A spatter of dried blood, a missing security badge, a suspicious suicide—a series of disturbing clues point to Calli’s twin sister, Carme, who’s been MIA for days.

This text revolves around a new and unusual view on the most fundamental puzzle of physics. It focuses on the key aspect that makes the role of the time dimension fundamentally different: causality. The implicit and intuitive way by which causality is usually taken for granted is just made explicit and less self-evident, shedding a new light on the gravity-quantum conflict. The case is made that gravity is a necessary condition for a causal universe.
