Când a descoperit legea gravitației, Newton a unificat regulile care guvernează cerurile și Pământul; de-atunci, fizicienii au tot așezat noi forțe în teorii tot mai cuprinzătoare. Însă provocarea supremă este realizarea unei sinteze monumentale a teoriei relativității și teoriei cuantice. Ar fi realizarea de căpătâi a științei, o fuziune profundă a tuturor forțelor naturii într-o singură ecuație minunată, care să descifreze cele mai profunde mistere ale științei: Ce s-a întâmplat înainte de Big Bang?

Each year,John Brockman, publisher of Edge.org, challenges some of the world's greatest scientists, artists, and philosophers to answer a provocative question crucial to our time. In 2014 he asked 175 brilliant minds to ponder: What scientific idea needs to be put aside in order to make room for new ideas to advance? The answers are as surprising as they are illuminating.

In 1927, Niels Bohr and Albert Einstein began a debate about the interpretation and meaning of the new quantum theory. This would become one of the most famous debates in the history of science. What (if any) limits should we place on our expectations for what science can tell us about physical reality? As Quantum Drama reveals, science owes a large debt to those who kept the discussions going before definitive experimental inquiries became possible. Although experiment moved the Bohr-Einstein debate to a new level, it has by no means removed or resolved the fundamental question.

An inspiring collection of essays, in which Albert Einstein addresses the topics that fascinated him as a scientist, philosopher, and humanitarian. Divided by subject matter - “Science,” “Convictions and Beliefs,” “Public Affairs,” etc. - these essays consider everything from the need for a “supranational” governing body to control war in the atomic age, to freedom in research and education, to Jewish history and Zionism, to explanations of the physics and scientific thought that brought him world recognition.

Breakthrough takes us on a breathtaking, mind-altering tour of the eureka! moments of modern physics. Charting the spellbinding stories of the scientists who predicted and discovered the existence of unknown planets, black holes, invisible force fields, ripples in the fabric of space-time, unsuspected subatomic particles and even antimatter, Marcus Chown reveals science's greatest mystery: its astonishing predictive power.

Why does your weather app say “there’s a 10 percent chance of rain” instead of “it will be sunny”? In large part, this is due to the insight of award-winning physicist Tim Palmer, who pioneered the introduction of uncertainty into weather and climate prediction. Now, he wants to apply it to how we study everything else.

The Quantum Rules applies the laws of physics to explain everything from relationships and human nature to the effects of globalization. It achieves the impossible task of making quantum physics deeply relevant to all listeners - even those with no interest in science. With a lively and engaging tone, author Kunal Das ponders the underlying truths and patterns in our shared and common life experiences, using insights derived from the fundamental laws of physics.

Einstein’s revolutionary scientific ideas have transformed our world, ushering in the nuclear age. The current pace of scientific and technological progress is simply astounding. So is there any place for faith in such a world? Einstein himself gave careful thought to the deepest questions of life. His towering intellectual status means he is someone worth listening to when we think through the big questions of life.

Winner of the Nobel Prize in Physics and author of the classic The First Three Minutes, Weinberg shares his views on some of the most fundamental and fascinating aspects of physics and the universe. But he does not seclude science behind disciplinary walls or shy away from politics, taking on what he sees as the folly of manned spaceflight, the harms of inequality, and the importance of public goods. His point of view is rationalist, realist, reductionist, and devoutly secularist.

This short, smart book tells you everything you need to know about "nothing". What remains when you take all the matter away? Can empty space - "nothing" - exist? To answer these questions, eminent scientist Frank Close takes us on a lively and accessible journey that ranges from ancient ideas and cultural superstitions to the frontiers of current research, illuminating the story of how scientists have explored the void and the rich discoveries they have made there.

The universe is a vast, mysterious, and incredibly cool place. It’s filled with things so strange and wonderful they can make your head spin. From the tiniest particles buzzing around beneath the surface of reality to the largest structures stretching across billions of light-years, the cosmos is packed with surprises. And the more we learn, the more we realize just how much we don’t know. When you glance up at the night sky, you’re not just looking at stars. You’re peering into the deep past, through millions or even billions of years.

In the summer of 1921, Philo T. Farnsworth was not all that different from any other farmer's son in rural Idaho, until he came up with an idea that would change the world–and thrust him into a titanic struggle with one of the most monolithic monopolies in the world. Farnsworth's story of divine inspiration facing off against corporate avarice is a compelling–though seldom told–saga from the 20th century that is still relevant in the 21st.

How we ultimately gained the American Customary System, the last traditional system in the world, and how Gunter's chain indelibly imprinted its dimensions on the land, on cities, and on our culture from coast to coast is both an exciting human and intellectual drama and one of the great untold stories in American history. Sagely argued and beautifully written, Measuring America offers readers nothing less than the opportunity to see America's history, and our democracy, in a brilliant new light.

For going on two decades, Scientific American’s “Ask the Experts” column has been answering reader questions on all fields of science. We’ve taken your questions from the basic to the esoteric and reached out to top scientists, professors, and researchers to find out why the sky is blue or whether we really only use 10 percent of our brains. Now, we’ve combed through our archives and have compiled some of the most interesting questions (and answers) into a series of books.

Einstein's steadfast refusal to accept certain aspects of quantum theory was rooted in his insistence that physics has to be about reality. Accordingly, he once derided as spooky action at a distance the notion that two elementary particles far removed from each other could nonetheless influence each others propertiesa hypothetical phenomenon his fellow theorist Erwin Schrdinger termed quantum entanglement.

The theoretical physicist shares his thoughts on the nature of space and time in this anthology of selections from Princeton University Press. Along with eminent colleagues, Hawking extends theoretical frontiers by speculating on the big questions of modern cosmology.

Teletransporte, máquinas del tiempo, campos de fuerza y naves intergalácticas: ¿materia de ciencia ficción o tecnologías potencialmente disponibles en el futuro? Inspirado por los mundos fantásticos de H.G. Wells, Star Trek o La guerra de las galaxias, el prestigioso físico teórico y divulgador Michio Kaku lanza una mirada inteligente, seria y a menudo sorprendente a lo que nuestra actual comprensión de las leyes del universo nos permite vislumbrar en el futuro.

Humanity has long looked to the sky and marveled at the world around us. We've wondered why the world is the way it is and whether it has to be that way. And we dream of a time when we have developed a theory of everything—a theory that answers all questions. Einstein's Unfinished Dream explores the cutting-edge research of modern particle physicists that pushes us slowly towards a theory of everything....

What happens when particles lose their individuality and merge into a single quantum being? This is the mystery of the Bose–Einstein condensate — a state of matter predicted by Einstein and Bose a century ago, first realized with ultracold atoms in the 1990s, and later extended to photons, exciton–polaritons, and other exotic systems. In this book, Boris Kriger guides the listener through the history of this extraordinary discovery — from a letter written in Calcutta to Einstein, to the Nobel-winning experiments that cooled atoms to the edge of absolute zero.

Homesteading Space is more than a story of technological and scientific success; it is also an absorbing, sometimes humorous, often inspiring account of the determined, hardworking individuals who shepherded the program through a near-disastrous launch, a heroic rescue, an exhausting study of Comet Kohoutek, and the lab's descent into the Indian Ocean. Featuring the unpublished in-flight diary of astronaut Alan Bean, it is replete with the personal recollections and experiences of the Skylab crew and those who worked with them in training, during the mission, and the return.
