Engineering Physics

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

For centuries, electricity was seen as little more than a curious property of certain substances that sparked when rubbed. Then, in the 1790s, Alessandro Volta began the scientific investigation that ignited an explosion of knowledge and invention. The force that once seemed inconsequential was revealed to be responsible for everything from the structure of the atom to the functioning of our brains. In harnessing its power, we have created a world of wonders—complete with roller coasters and radar, computer networks and psychopharmaceuticals.

Did NASA really spend millions creating a pen that would write in space? Is chocolate poisonous to dogs? Does stress cause gray hair? These questions are a sample of the urban lore investigated in this audiobook, Fact or Fiction: Science Tackles 58 Popular Myths. Drawing from Scientific American’s “Fact or Fiction” and “Strange But True” columns, we’ve selected 58 of the most surprising, fascinating, useful, and just plain wacky topics confronted by our writers over the years.

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.

Un homme qui a profondément changé notre vision du monde S'il est quelqu'un que l'on peut qualifier de génie, c'est certainement Einstein. Il a façonné la physique du XXème siècle. Non seulement ses découvertes ont permis l'avènement de notre univers technologique (électronique, laser, énergie nucléaire, etc.), mais surtout, il a profondément modifié notre conception du monde. Il y a un avant Einstein et un après Einstein qui se prolonge aujourd'hui puisque ses théories n'ont pas, pour l'essentiel, été démenties. Inventeur des deux grandes théories du XXe : relativité et théorie quantique.

The Physics of Life argues that the evolution phenomenon is much broader and older than the evolutionary designs that constitute the biosphere, empowering listeners with a new view of the globe and the future, revealing that the urge to have better ideas has the same physical effect as the urge to have better laws and better government. This is evolution explained loudly but also elegantly, forging a path that flows sustainability.

In 1695, Isaac Newton already renowned as the greatest mind of his agemade a surprising career change. He left quiet Cambridge, where he had lived for 30 years and made his earth-shattering discoveries, and moved to London to take up the post of Warden of His Majestys Mint. Newton was preceded to the city by a genius of another kind, the budding criminal William Chaloner.

A physicist speeds across space, time, and everything in between showing that our elegant universe from the Higgs boson to antimatter to the most massive group of galaxies is shaped by hidden symmetries that have driven all our recent discoveries about the universe and all the ones to come. Why is the sky dark at night? Is it possible to build a shrink-ray gun? If there is antimatter, can there be antipeople? Why are past, present, and future our only options? Are time and space like a butterfly's wings? No one but Dave Goldberg, the coolest nerd physicist on the planet, could give a hyper-drive tour of the universe like this one.

Neuroscientists have painstakingly built up an understanding of the structure of the brain. Could this help physicists understand the levels of self-organization they observe in other systems? These same physicists, meanwhile, are trying to explain how particles organize themselves into the objects around us. Could their discoveries help explain how neurons produce our conscious experience? Exploring these questions and more, George Musser tackles the extraordinary interconnections between quantum mechanics, cosmology, human consciousness, and artificial intelligence.

Computer technology has improved exponentially over the last 50 years. But the headroom for bigger and better electronic solutions is running out. Our best hope is to engage the power of quantum physics. “Quantum algorithms” had already been written long before hardware was built. These would enable, for example, a quantum computer to exponentially speed up an information search or crack the mathematical trick behind internet security.

Lighthearted, quirky, and upbeat, this book explores the portrayal of science and technology on both the big and little screen - and how Hollywood is actually doing a better job of getting it right than ever before. Grounded in the real-word, and often cutting-edge, science and technology that inspires fictional science, the authors survey Hollywood depictions of topics such as quantum mechanics, parallel universes, and alien worlds.

As we navigate through life we instinctively model time as having a flowing present that divides a fixed past from open future. This model develops in childhood and is deeply saturated within our language, thought, and behavior, affecting our conceptions of the universe, freedom, and the self. Yet as central as it is to our lives, physics seems to have no room for this flowing present. What Makes Time Special? demonstrates this claim in detail and then turns to two novel positive tasks.

Escucha ahora la biografía definitiva de Albert Einstein, uno de los iconos del siglo XX y su mayor genio.

De la théorie de la relativité formulée par Albert Einstein, en passant par les recoins et les mécanismes de notre cerveau pour faire fonctionner notre mémoire jusqu’à la découverte des secrets de l'anatomie humaine… la science n’aura plus aucun mystère pour vous. En partenariat avec « L’Éléphant, la revue de culture générale ». Comment est-on parvenu à reconstituer la chronologie de l'histoire de la Terre ? Comment explique t-on le hasard ? Et si modifier de l’ADN était aussi facile qu'un simple copier-coller dans un traitement de texte ?

From Schrodinger's cat to Heisenberg's uncertainty principle, this book untangles the weirdness of the quantum world. Quantum mechanics underpins modern science and provides us with a blueprint for reality itself. And yet it has been said that if you're not shocked by it, you don't understand it. But is quantum physics really so unknowable? Is reality really so strange? And just how can cats be half alive and half dead at the same time?

Following the discovery of the Higgs boson, Frank Close has produced this major revision to his classic and compelling introduction to the fundamental particles that make up the universe. Frank Close takes us on a journey into the atom to examine known particles such as quarks, electrons, and the ghostly neutrino, and explains the key role and significance of the Higgs boson. Along the way he provides fascinating insights into how discoveries in particle physics have actually been made, and discusses how our picture of the world has been radically revised in the light of these developments.

Since the 1950s, scientists have attempted to harness nuclear fusion—the process that creates the Sun's energy—to generate near-limitless amounts of electricity. But the fact that we still have no fusion power plants is testament to the complexities of the challenge. Now, the deepening climate crisis means that researchers around the world are in a race to create a mini-Sun here on Earth. The glittering prize is an energy source that emits no greenhouse gases and could solve energy equity and supply issues at a stroke.

Many people are fed up with the way traditional religion alienates them. Too easily it perpetuates conflict, vilifies science, and undermines reason. Nancy Abrams - a philosopher of science, lawyer, and lifelong atheist - is among these people, but she has also found freedom in imagining a higher power. Here, Abrams explores a radically new way of thinking about God. She shows why an omniscient, omnipotent God that created the universe and plans what happens is incompatible with science - but that this doesn’t preclude a God that can comfort and empower us.

In 1965, the great American physicist Richard Feynman famously proclaimed, "I think I can safely say that nobody understands Quantum Mechanics." Is there any wonder why? Particles that pop in and out of existence... Spooky action at a distance that travels faster than light... Infinite universes and branching realities? In this book, we will break through the confusion and reveal to you the most important ideas of Quantum Physics, told through the amazing true story of just 4 bizarre discoveries.

What is the nature of the material world? How does it work? What is the universe and how was it formed? What is life? Where do we come from and how did we evolve? How and why do we think? What does it mean to be human? How do we know? There are many different versions of our creation story. This book tells the version according to modern science. It is a unique account, starting at the Big Bang and travelling right up to the emergence of humans as conscious intelligent beings, 13.8 billion years later.
