In this absorbing and frequently contentious book, Roger Penrose puts forward his view that there are some facets of human thinking that can never be emulated by a machine. The book's central concern is what philosophers call the "mind-body problem". Penrose examines what physics and mathematics can tell us about how the mind works, what they can't, and what we need to know to understand the physical processes of consciousness.

El prestigioso físico teórico Michio Kaku expone en Supremacía cuántica todas las promesas y los escollos que pueden surgir a partir del uso del ordenador cuántico, del que se espera que permita desvelar algunos de los mayores misterios de nuestro universo y resolver muchos de nuestros principales problemas.

Cuando Newton formuló la ley de la gravedad, unificó las reglas que rigen los cielos y la Tierra. Hoy el mayor desafío de la física es encontrar una síntesis de las dos grandes teorías, basadas en principios matemáticos diferentes: la de la relatividad y la cuántica. Combinarlas sería el mayor logro de la ciencia, una profunda fusión de todas las fuerzas de la naturaleza en una hermosa y magnífica ecuación que nos permitiría comprender los misterios más profundos del universo.

Atomic weaponry is widely understood as a story of American scientific achievement—but scientists working in Britain played a vital role in its development. Including Nobel Prize winners and Jewish refugees from Nazi Germany, these scientists have long since been forgotten. But without their expertise, Robert Oppenheimer's research at Los Alamos would never have succeeded. Gareth Williams unearths the true story of the top-secret British atomic program, codenamed "Tube Alloys," established in 1940.

Speed limits. Internet speeds. The speed of Earth. There are so many aspects of human life that are ruled by speed, even if we don’t realize it everyday. In this best of Seeker collection, you’ll learn how we decide speed limits, how fast a thought travels, how much acceleration the human body can take, and the simple discovery that let us fly faster than the speed of sound.

There are thousands of planes above your head right now, but how do we keep track of all of them at the same time? Take yourself to virtual flight school and learn all about how planes fly, how we breathe on airplanes, and the technology behind hypersonic travel and how we’re able to fly faster than the speed of sound. You’ll also explore the world of aviation, from the Wright Brothers’ first flight to the future of airplanes in this bite-sized collection from Seeker, available for the first time in audio.

Black holes are some of the most mystifying and mysterious parts of our galaxy. How big can a black hole get? Do black holes ever die? What does it sound like when black holes smash into each other? Learn the answers to all of these questions and more in this fascinating look into the phenomena scientists are learning more about every day.

The hunt for the Higgs particle has involved the biggest, most expensive experiment ever. So exactly what is this particle? Why does it matter so much? What does it tell us about the universe? Was finding it really worth all the effort? The short answer is yes. The Higgs field is proposed as the way in which particles gain mass - a fundamental property of matter. It's the strongest indicator yet that the Standard Model of physics really does reflect the basic building blocks of our universe. Little wonder the hunt and discovery of this new particle produced such intense media interest.

Best-selling author, superstar physicist, and cofounder of the World Science Festival Brian Greene (The Elegant Universe, The Fabric of the Cosmos) and an ensemble cast led by award-winning actor Paul Rudd (Ant-Man) perform this dramatic story tracing Albert Einstein's discovery of the general theory of relativity.

" 18 avril 2018 : Shojiro Takejama appuie sur le bouton rouge qui déclenche son expérience. Boum ! Dans l'explosion qui s'ensuit et qui manque de détruire le laboratoire, le chercheur parvient à produire le champ magnétique le plus intense au monde : 1 000 fois celui qui règne dans un tunnel d'IRM.

Is the world around us real—or is it a construct, a mirage generated by a powerful and incomprehensibly advanced intelligence? This question, once confined to the pages of science fiction novels and speculative late-night discussions, has in recent years migrated into the heart of contemporary philosophical and scientific inquiry. The idea that our universe might be an elaborate simulation, running on an immense computational substrate, is no longer dismissed as a fringe hypothesis. Instead, it is now taken seriously by physicists, cosmologists, computer scientists, and philosophers alike.

A New York Times bestseller! The historic race that reawakened the promise of manned spaceflight A Finalist for the PEN/E. O. Wilson Literary Science Writing Award Alone in a Spartan black cockpit, test pilot Mike Melvill rocketed toward space. He had eighty seconds to exceed the speed of...

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 ?

For fans of The Astronaut Wives Club, The Mercury 13 reveals the little-known true story of the remarkable women who trained for NASA space flight. In 1961, just as NASA launched its first man into space, a group of women underwent secret testing in the hopes of becoming America’s first female astronauts. They passed the same battery of tests at the legendary Lovelace Foundation as did the Mercury 7 astronauts, but they were summarily dismissed by the boys’ club at NASA and on Capitol Hill.

Beyond dares to imagine a fantastic future for humans in space - and then reminds us that we're already there. Human exploration has been an unceasing engine of technological progress, from the first homo sapiens to leave our African cradle to a future in which mankind promises to settle another world. Beyond tells the epic story of humanity leaving home - and how humans will soon thrive in the vast universe beyond the Earth.
