What happened before the Big Bang? Why does time flow only forward? Do we live as part of a multiverse? Could the universe vanish in an instant? These questions and more are at the forefront of physics, cosmology, and quantum theory, and they keep some of the best minds of modern physicists awake at night. The Great Unanswered Questions of Physics gives you the chance to probe these mysteries of the universe.

In the years following her role as the lead author of the international best seller, Limits to Growth - the first book to show the consequences of unchecked growth on a finite planet - Donella Meadows remained a pioneer of environmental and social analysis until her untimely death in 2001. Thinking in Systems is a concise and crucial book offering insight for problem-solving on scales ranging from the personal to the global. Edited by the Sustainability Institute's Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world....

Die moderne Physik hat die Medizin umgekrempelt. Ärztinnen und Ärzte können heute ganz selbstverständlich in den lebendigen Menschen schauen – ohne den kleinsten Schnitt in die Haut. Verletzungen und Erkrankungen lassen sich damit so präzise erkennen wie nie zuvor. Und sogar Heilen kann die Physik! Wo eine Operation nicht ausreicht, können verschiedene Arten von Strahlung etwa Tumore bekämpfen.

In this 24-lesson course aimed at non-scientists, noted particle physicist Dr. Don Lincoln of Fermi National Accelerator Laboratory covers more than a century of progress in physics, describing exactly how scientists reach the conclusions they do. He starts with the atom, which was long hypothesized but wasn’t definitively proven until a paper by Albert Einstein in 1905. That was just the beginning, as researchers probed ever deeper into the atom’s complex structure, leading to the weird findings of quantum mechanics.

What is the nature of space and time? How do we fit within the universe? How does the universe fit within us? There's no better guide through these mind-expanding questions than acclaimed astrophysicist and best-selling author Neil deGrasse Tyson. But today, few of us have time to contemplate the cosmos. So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities: bouncing and cyclic universes, time loops, creations from nothing, multiverses, black hole births, string theories, and holograms. Along the way, they offer both a call for new physics and a riveting story of scientific debate.

Cosmos is one of the bestselling science books of all time. In clear-eyed prose, Sagan reveals a jewel-like blue world inhabited by a life form that is just beginning to discover its own identity and to venture into the vast ocean of space.

Reality is not what it seems. Not fixed. Not silent. Not separate from the one who observes it. Quantum experiments reveal seams in the world… places where information appears without traveling… where outcomes wait for attention… where time behaves like something far more flexible than a river. These seams form a doorway. A narrow line where darkness gives way to light… where the familiar dissolves into the possible… where a question becomes the beginning of understanding. This book does not claim answers. It offers a key. If you have ever sensed something beneath the surface… Step closer.

What is Now? This immediate moment, what we're experiencing right now . . . it bathes us like air, or gravity. Yet when we try to grasp this quality, to scrutinize it or bring it into focus, it vanishes, slipping through our fingers like a dream. And worse, according to the most trusted models of physics, Now doesn't even exist. If all this is so, then what, exactly, are we experiencing? How do we carve out time, sensation, self, and meaning from a blank, Now-less canvas?

Histories of science in the 20th century have focused on relativity and quantum mechanics. But, quietly in the background, there has been a third area of exploration that has equally important implications for our understanding of the universe. It is unknown to the general public, despite the fact that many Nobel prize winners, senior academics and major research centres around the world have been devoted to it - it is the study of plasma.

Chemistry and Our Universe: How It All Works is your in-depth introduction to this vital field, taught through 60 engaging half-hour lectures that are suitable for any background or none at all. Covering a year’s worth of introductory general chemistry at the college level, plus intriguing topics that are rarely discussed in the classroom, this amazingly comprehensive course requires nothing more advanced than high-school math. Your guide is Professor Ron B. Davis, Jr., a research chemist and award-winning teacher at Georgetown University.

Over the last 220 years, society has evolved a universal belief that electricity is "safe" for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before - from an environmental point of view - by detailing the effects that this fundamental societal building block has had on our health and our planet.

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.

"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.

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.

America’s favorite astrophysicist has written the most entertaining and universally appealing book of his stellar career: a practical guide for dealing with Alien visitors, an exploration of how it might happen, and a cultural history of our fascination with extraterrestrials. “Ever since...
