Engineering Physics

All the matter and light we can see in the universe makes up a trivial five per cent of everything. The rest is hidden. This could be the biggest puzzle that science has ever faced. Since the 1970s, astronomers have been aware that galaxies have far too little matter in them to account for the way they spin around: they should fly apart, but something concealed holds them together. That ’something' is dark matter - invisible material in five times the quantity of the familiar stuff of stars and planets.

Where did the universe come from? What was there before it? What will the future bring? And finally, why is there something rather than nothing? Krauss’ answers to these and other timeless questions, in a wildly popular lecture on YouTube, has attracted almost a million viewers. One of the few prominent scientists to have actively crossed the chasm between science and popular culture, Krauss reveals that modern science is indeed addressing the question of why there is something rather than nothing—with surprising and fascinating results.

Science is fantastic. It tells us about the infinite reaches of space, the tiniest living organism, the human body, the history of Earth. People have always been doing science because they have always wanted to make sense of the world and harness its power. From ancient Greek philosophers through Einstein and Watson and Crick to the computer-assisted scientists of today, men and women have wondered, examined, experimented, calculated, and sometimes made discoveries so earthshaking that people understood the world-or themselves-in an entirely new way.

Vier Forscher und ein unablässiges Hin und Her der Ideen – vor hundert Jahren entstand eine neue Wissenschaft, die die Grenzen der Vorstellungskraft sprengte: die Quantenphysik. Ihre Protagonisten: Max Planck, Albert Einstein, Niels Bohr und Werner Heisenberg. Sie ergründeten das Innere der Atome und rangen mit einer scheinbar einfachen Frage: Was ist Licht? – zu einer Zeit, in der Elektrizität erstmals die Städte erhellte und Kino und Fotografie ihren Siegeszug antraten. Thomas de Padova lässt die fieberhafte Suche nach Antworten anhand der Begegnungen der Forscher lebendig werden.

In June 1925, 23-year-old Werner Heisenberg, suffering from hay fever, retreated to a small, treeless island in the North Sea called Helgoland. It was there that he came up with one of the most transformative scientific concepts: quantum theory. Almost a century later, quantum physics has given us many startling ideas: ghost waves, distant objects that seem magically connected to each other, cats that are both dead and alive. Today our understanding of the world around us is based on this theory. And yet it is still profoundly mysterious.

There seems to be evidence to suggest that our world and everything in it are only ghostly images: projections from a level of reality so beyond our own that the real reality is literally beyond both space and time. The main architect of this astonishing idea is one of the world’s most eminent thinkers - physicist David Bohm, a protégé of Einstein’s. In this executive summary, Chuck gives a current perspective on some of the areas that define our reality.

Drawing on quantum mechanics, thermodynamics, chaos and complexity theory, materials science and more, The Art of Physics reveals the hidden, surprising, and sometimes beautiful ways in which physics can help us to make sense of an unpredictable world. Ultimately, it shows how by embracing the paradoxes and uncertainty at the core of physics, we can unlock a deeper understanding of ourselves and our universe.

How does the physics we know today - a highly professionalized enterprise, inextricably linked to government and industry - link back to its origins as a liberal art in Ancient Greece? What is the path that leads from the old philosophy of nature and its concern with humankind's place in the universe to modern massive international projects that hunt down fundamental particles and industrial laboratories that manufacture marvels? This audiobook introduces us to Islamic astronomers and mathematicians calculating the size of the Earth while their caliphs conquered much of it and more.

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 recognized 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?

In Three Roads to Quantum Gravity, Lee Smolin provides an accessible overview of the attempts to build a final "theory of everything." He explains in simple terms what scientists are talking about when they say the world is made from exotic entities such as loops, strings, and black holes and tells the fascinating stories behind these discoveries: the rivalries, epiphanies, and intrigues he witnessed firsthand.

Does the universe embody beautiful ideas? Artists as well as scientists throughout human history have pondered this "beautiful question". With Nobel laureate Frank Wilczek as your guide, embark on a voyage of related discoveries, from Plato and Pythagoras up to the present. Wilczek's groundbreaking work in quantum physics was inspired by his intuition to look for a deeper order of beauty in nature.

For the first time in history, the secrets of the living brain are being revealed by a battery of high-tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist.

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

Why does it feel like something to be alive? For one of the boldest thinkers in neuroscience, solving this puzzle has been a lifetime's quest. Now at last, Mark Solms, who discovered the brain mechanism for dreaming, has arrived at his answer. More than just a philosophical argument, the Free Energy theory will profoundly change how you understand your own existence.

The Skeptics' Guide to the Universe is your map through this maze of modern life. Here Dr. Steven Novella and friends will explain the tenets of skeptical thinking and debunk some of the biggest scientific myths, fallacies, and conspiracy theories - from anti-vaccines to homeopathy, UFO sightings to N-rays. You'll learn the difference between science and pseudoscience, essential critical thinking skills, ways to discuss conspiracy theories with that crazy co-worker of yours, and how to combat sloppy reasoning, bad arguments, and superstitious thinking.

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.

If you were to present the feats of modern science to someone from the past, those feats would surely be considered magic. Theoretical physicist Felix Flicker proves that they are indeed magic—just familiar magic. The name for this magic is “condensed matter physics.” Most people haven’t heard of the field, yet more than a third of physicists identify as condensed matter researchers, making it the most active area in the subject—with good reason. Condensed matter is the solids, liquids, and gasses that surround us—and the more exotic matters—which dictate every aspect of our present existence.

During the last 50 years, numerous physicists have tried to unravel the secrets of string theory. Yet why do these scientists work on a theory lacking experimental confirmation? Why String Theory? provides the answer, offering an easily understood and accessible panorama of the who, what, and why of this large aspect of modern theoretical physics.

Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.

Throughout history, arguments for and against the existence of God have been largely confined to philosophy and theology, while science has sat on the sidelines. Despite the fact that science has revolutionized every aspect of human life and greatly clarified our understanding of the world, somehow the notion has arisen that it has nothing to say about the possibility of a supreme being, which much of humanity worships as the source of all reality.
