Gravity is the weakest force in the everyday world, yet it is the strongest force in the universe. It was the first force to be recognised and described, yet it is the least understood. It is a 'force' that keeps your feet on the ground, yet no such force actually exists. Gravity, to steal the words of Winston Churchill, is 'a riddle wrapped in a mystery inside an enigma'. And penetrating that enigma promises to answer the biggest questions in science: what is space? What is time? What is the universe? And where did it all come from?

Throughout history, thinkers from mathematicians to theologians have pondered the mysterious relationship between numbers and the nature of reality. In this fascinating book, Mario Livio tells the tale of a number at the heart of that mystery: phi, or 1.6180339887.... This curious mathematical relationship, widely known as "The Golden Ratio", was discovered by Euclid more than 2,000 years ago. Since then it has shown a propensity to appear in the most astonishing variety of places.

The authoritative story of the headline-making discovery of gravitational waves - by an eminent theoretical astrophysicist and award-winning writer.

Consider these commonly held scientific beliefs: Planetary orbits are fixed ellipses; we only use 10 percent of our brains; nothing travels faster than light; a thrown object’s trajectory is a parabola. They seem correct, but they’re all misconceptions that aren’t entirely accurate. There’s much more to the story than you think. These magnificent 24 lectures are devoted to busting myths, clearing up confusion, and giving you scientific epiphanies that could change how you think about your everyday world.

Our naked eyes see only a thin sliver of reality. We are blind in comparison to the X-rays that peer through skin, the mass spectrometers that detect the dead inside the living or the high-tech surveillance systems that see with artificial intelligence. And we are blind compared to the animals that can see in infrared, or ultraviolet, or in 360-degree vision. These animals live in the same world we do, but they see something quite different when they look around.

This 10-part history of mathematics reveals the personalities behind the calculations: the passions and rivalries of mathematicians struggling to get their ideas heard. Professor Marcus du Sautoy shows how these masters of abstraction find a role in the real world and proves that mathematics is the driving force behind modern science.

The most important things in life are our health and happiness. Yet most of us are neither healthy nor happy. We have been led to believe that if we think ahead and make the right choices, we can manifest our dreams. Yet despite our best efforts, we still have more disease and discontent than ever before. Is it possible that our essential ideas about life are flawed? We are all aware of the impact of sunlight on a plant's growth and development. But few of us realize that a plant actually "sees" where light is emanating from and positions itself to be in optimal alignment with it.

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.

Carl Sagan, writer and scientist, returns from the frontier to tell us about how the world works. In his delightfully down-to-earth style, he explores and explains a mind-boggling future of intelligent robots, extraterrestrial life and its consequences, and other provocative, fascinating quandaries of the future that we want to see today.

The Great Courses has produced thousands of lectures that have introduced millions of lifelong learners to some of the biggest and most fascinating ideas that humans have ever thought. Now, enjoy 36 lectures specially curated from some of our most popular courses and get an interesting learning experience across a wide range of disciplines.

Quantum Psychology holistically approaches challenges and basic conceptions about the way reality reveals itself that we take for granted, re-thinking them from a new prism. It questions the very same foundations of our existence and what "being" truly encompasses. This is a journey to interpret our reality and your role in its unfolding as never imagined before. You might love it or disagree with it, but you will not be left indifferent.

Oxford mathematician and author John Lennox takes a closer look at Hawking's logic regarding what brought the universe into being. In lively, layman's terms, Lennox guides us through the key points in Hawking's arguments - with clear explanations of the latest scientific and philosophical methods and theories - and demonstrates that far from disproving a creator God, they make his existence seem all the more probable.

Why does one smoker die of lung cancer but another live to 100? The answer is 'The Hidden Half' - those random, unknowable variables that mess up our attempts to comprehend the world. We humans are very clever creatures - but we're idiots about how clever we really are. In this entertaining and ingenious book, Blastland reveals how in our quest to make the world more understandable, we lose sight of how unexplainable it often is. The result - from GDP figures to medicine - is that experts know a lot less than they think.

Inspired by Albert Einstein's theory of relativity and Bertrand Russell and David Hilbert's pursuit of the fundamental rules of mathematics, some of the most brilliant minds of the generation came together in post-World War I Vienna to present the latest theories in mathematics, science, and philosophy and to build a strong foundation for scientific investigation. Composed of such luminaries as Kurt Gödel and Rudolf Carnap, and stimulated by the works of Ludwig Wittgenstein and Karl Popper, the Vienna Circle left an indelible mark on science.

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.

In Calculating the Cosmos, Ian Stewart presents an exhilarating guide to the cosmos, from our solar system to the entire universe. He describes the architecture of space and time, dark matter and dark energy, how galaxies form, why stars implode, how everything began, and how it's all going to end. He considers parallel universes, the fine-tuning of the cosmos for life, what forms extraterrestrial life might take, and the likelihood of life on Earth being snuffed out by an asteroid.

Can there be freedom and free will in a deterministic world? Renowned philosopher Daniel Dennett emphatically answers "yes!" Using an array of provocative formulations, Dennett sets out to show how we alone among the animals have evolved minds that give us free will and morality. Weaving a richly detailed narrative, Dennett explains in a series of strikingly original arguments - drawing upon evolutionary biology, cognitive neuroscience, economics, and philosophy - that far from being an enemy of traditional explorations of freedom, morality, and meaning, the evolutionary perspective can be an indispensable ally.

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.

From the ancient Greeks to Buddhism, our ability to check reality and recalibrate has fascinated philosophers for thousands of years. Yet it is only recently that we've developed the technology to create a rigorous science of self-awareness, what we call metacognition. Head of the Metacognition Lab at University College London, Stephen Fleming is the world's leading expert in this new field of neuroscience. In Know Thyself, he explains both the vast potential of metacognition and why it is that we still so often get it wrong.
