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.

From one of the world’s leading data scientists, a landmark tour ofthe new science of idea flow, offering revolutionary insights into the mysteries of collective intelligence and social influence.

Werner Heisenberg's "uncertainty principle" challenged centuries of scientific understanding, placed him in direct opposition to Albert Einstein, and put Niels Bohr in the middle of one of the most heated debates in scientific history. Heisenberg's theorem stated that there were physical limits to what we could know about sub-atomic particles; this "uncertainty" would have shocking implications.

One of the great insights of science is that the universe has an underlying order. The supreme goal of physicists is to understand this order through laws that describe the behavior of the most basic particles and the forces between them. For centuries, we have searched for these laws by studying the results of experiments. Since the 1970s, however, experiments at the world's most powerful atom-smashers have offered few new clues. So some of the world's leading physicists have looked to a different source of insight: modern mathematics.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

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.

Stephen Hawking’s worldwide best seller A Brief History of Time remains a landmark volume in scientific writing. But for those who have asked for a more accessible formulation of its key concepts - the nature of space and time, the role of God in creation, and the history and future of the universe - A Briefer History of Time is Professor Hawking’s response.

When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s 35-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter - one that raises the possibility of new materials with never-before-seen properties but that violates laws set in stone for centuries.

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.

As smartphones, supercomputers, supercolliders, and AI propel us into an ever more unfamiliar future, How to Speak Science takes us on a rollicking historical tour of the greatest discoveries and ideas that make today's cutting-edge technologies possible. Wanting everyone to be able to "speak" science, YouTube science guru Bruce Benamran explains - as accessibly and wittily as in his acclaimed videos - the fundamental ideas of the physical world: matter, life, the solar system, light, electromagnetism, thermodynamics, special and general relativity, and much more.

James Gleick's story begins at the turn of the 20th century, with the young H. G. Wells writing and rewriting the fantastic tale that became his first book, an international sensation: The Time Machine. A host of forces were converging to transmute the human understanding of time, some philosophical and some technological - the electric telegraph, the steam railroad, the discovery of buried civilizations, and the perfection of clocks.

For more than 50 years, the world's top scientists searched for the "missing" planet Vulcan, whose existence was mandated by Isaac Newton's theories of gravity. Countless hours were spent on the hunt for the elusive orb, and some of the era's most skilled astronomers even claimed to have found it. There was just one problem: It was never there.

In this 1972 treatise, Isaac Asimov takes the listener on an historic journey through the development of man's understanding of electricity, chemistry, and - ultimately - nuclear energy. Asimov's incomparable ability to simplify the complex is apparent as he guides you through the milestones of scientific thought that connected ideas about electricity and magnetism to the nature of matter, and led to the advances in discovery through the first half of the 20th century that resulted in the harnessing of previously unknown energy directly from the heart of the atom.

Every one of us contains a billion times more atoms than all the grains of sand in the earth’s deserts. If you weigh 150 pounds, you’ve got enough carbon to make 25 pounds of charcoal, enough salt to fill a saltshaker, enough chlorine to disinfect several backyard swimming pools, and enough iron to forge a 3-inch nail. But how did these elements combine to make us human?

Big History, the field that studies the entire known past of our universe to give context to human existence, has so far been the domain of historians. Geologist Walter Alvarez - best known for his Impact Theory explaining dinosaur extinction - makes a compelling case for a new, science-first approach to Big History.

They say you can't teach an old dog new tricks. But what about relativity? Physics professor Chad Orzel and his inquisitive canine companion, Emmy, tackle the concepts of general relativity in this irresistible introduction to Einstein's physics. Through armchair- and sometimes passenger-seat-conversations with Emmy about the relative speeds of dog and cat motion or the logistics of squirrel-chasing, Orzel translates complex Einsteinian ideas into examples simple enough for a dog to understand.

Prepare to learn everything we still don’t know about our strange and mysterious Universe. Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore - there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the Universe: The enormous holes in our knowledge of the cosmos. Armed with entertaining and lucid explanations of science, they give us the best answers currently available.

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.
