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?

People are used to seeing "fake physics" in science fiction - concepts like faster-than-light travel, antigravity, and time travel to name a few. The fiction label ought to be a giveaway, but some SF writers - especially those with a background in professional science - are so adept at "technobabble" that it can be difficult to work out what is fake and what is real. To confuse matters further, Isaac Asimov's 1948 piece about the fictitious time-traveling substance thiotimoline was written, not as a short story, but in the form of a spoof research paper.

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.

The story is about a two-dimensional world referred to as Flatland. All existence is limited to length and breadth in Flatland, its inhabitants unable even to imagine a third dimension. The amiable narrator, A Square, provides an overview of this fantastic world---its physics and metaphysics, its history, customs, and religious beliefs. But when a strange visitor mysteriously appears and transports the incredulous Flatlander to Spaceland, a land of three dimensions, his worldview is forever shattered.

Classical physics is about how things move, why they move, and how they work. It's about making sense of motion, gravity, light, heat, sound, electricity, and magnetism, and seeing how these phenomena interweave to create the rich tapestry of everyday experience. It is, in short, the hidden order of the universe.

Albert Einstein and Erwin Schrödinger were friends and comrades-in-arms against what they considered the most preposterous aspects of quantum physics: its indeterminacy. Einstein famously quipped that God does not play dice with the universe, and Schrödinger is equally well known for his thought experiment about the cat in the box who ends up "spread out" in a probabilistic state, neither wholly alive nor wholly dead.

In the 1970s, amid severe cutbacks in physics funding, a small group of underemployed physicists in Berkeley decided to throw off the constraints of academia and explore the wilder side of science. Dubbing themselves the “Fundamental Fysiks Group,” they pursued a freewheeling, speculative approach to physics. Some dabbled with LSD while conducting experiments. They studied quantum theory alongside Eastern mysticism and psychic mind reading, discussing the latest developments while lounging in hot tubs.

In This Explains Everything, John Brockman, founder and publisher of Edge.org, asked experts in numerous fields and disciplines to come up with their favorite explanations for everyday occurrences. Why do we recognize patterns? Is there such a thing as positive stress? Are we genetically programmed to be in conflict with each other? Those are just some of the 150 questions that the world's best scientific minds answer with elegant simplicity.

From Descartes and Newton to Einstein and Bohr, Capra takes us on a journey through the past four centuries of the scientific revolution and leads us to the birth of a new worldview in response to the escalating world crises. He reveals the difficulty in translating abstract ideas to the screen, and how the use of visual metaphor became a powerful tool and symbolized the importance of the ecological dimension.

The Trouble with Physics argues that a limited notion of time is holding physics back. It's time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics. What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilities.

Una guida per tutti attraverso le rivoluzioni scientifiche che hanno sconvolto la fisica nel ventesimo secolo. Con folgorante chiarezza vengono qui spiegate la teoria della relatività generale di Einstein, la meccanica quantistica, i buchi neri, la complessa architettura dell'universo, le particelle elementari, la gravità e la natura del tempo e della mente: una limpida e divertente introduzione a quelle scoperte della fisica contemporanea che smentiscono ogni nostra percezione e intuizione immediata.

Would you like to know how the universe works? Scientists have been asking that question for a long time and have found that many of the answers can be found in the study of particle physics, the field that focuses on those impossibly tiny particles with unbelievably strange names - the hadrons and leptons, baryons and mesons, muons and gluons - so mystifying to the rest of us.

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

Welcome to the Universe is a personal guided tour of the cosmos by three of today's leading astrophysicists. Inspired by the enormously popular introductory astronomy course that Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott taught together at Princeton, this book covers it all - from planets, stars, and galaxies to black holes, wormholes, and time travel.

Astrophysicist Neil deGrasse Tyson has attracted one of the world’s largest online followings with his fascinating, widely accessible insights into science and our universe. Now, Tyson invites us to go behind the scenes of his public fame by unveiling his candid correspondence with people across the globe who have sought him out in search of answers. In this hand-picked collection of 100 letters, Tyson draws upon cosmic perspectives to address a vast array of questions about science, faith, philosophy, life, and of course, Pluto.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

Neil deGrasse Tyson has a talent for guiding readers through the mysteries of outer space with stunning clarity and almost childlike enthusiasm. This collection of his essays from Natural History magazine explores a myriad of cosmic topics. Tyson introduces us to the physics of black holes by explaining what would happen to our bodies if we fell into one; he also examines the needless friction between science and religion, and notes Earth's status as "an insignificantly small speck in the cosmos".

One of the biggest discoveries in physics, the quest for the Higgs boson demonstrates the value of a good theory. In July 2012, a Higgs-like particle was found near the energies scientists predicted. Now, armed with better evidence and better questions, the scientific process continues. In this audiobook, we’ve gathered our best reporting to explain that process - the theories, the search, the discovery, and the ongoing questions.

In this illuminating book, the renowned theoretical physicist Lee Smolin argues that fundamental physics - the search for the laws of nature - is losing its way. Ambitious ideas about extra dimensions, exotic particles, multiple universes, and strings have captured the publics imagination -- and the imagination of experts.

In Reconnecting to the Source he unpacks the science behind spiritual experience, investigating the ways in which we can access realms of experience beyond the everyday. It is in these moments, when our conscious minds are in contact or perhaps even overridden by our unconscious selves, that we can explore the depths of spiritual meaning. In addition to a foreword by Deepak Chopra, the book includes new, never before published contributions from a long list of well-known writers and public figures.
