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.

Since the fall of the Soviet Union, long-suppressed information has emerged on Heisenberg’s role in the Nazi atomic bomb project. In Beyond Uncertainty, Cassidy interprets this and other previously unknown material within the context of his vast research and tackles the vexing questions of a scientist’s personal responsibility and guilt when serving an abhorrent military regime.

Max Tegmark leads us on an astonishing journey through past, present and future, and through the physics, astronomy, and mathematics that are the foundation of his work, most particularly his hypothesis that our physical reality is a mathematical structure and his theory of the ultimate multiverse. In a dazzling combination of both popular and groundbreaking science, he not only helps us grasp his often mind-boggling theories, but he also shares with us some of the often surprising triumphs and disappointments that have shaped his life as a scientist.

Wenn xkcd.com einen neuen Science Cartoon postet, vibriert das Internet. Sein Blog "what if", auf dem der Physiker Randall Munroe jede Woche bizarre Fragen mit exakter Wissenschaft und genialen Strichmännchen beantwortet, ist Kult. Wie lange würde es dauern, bis wir merken würden, dass sich der Erdumfang verändert? Hätten wir genug Energie, um die ganze Weltbevölkerung von der Erde wegzubefördern? Wann (wenn überhaupt) wird Facebook mehr Profile von Toten als von Lebenden enthalten? Wenn man eine zufällige Nummer wählt und "Gesundheit!" sagt, wie hoch ist die Wahrscheinlichkeit, dass der Angerufene tatsächlich gerade geniest hat?

Have you ever wondered what it would be like to find yourself strapped to a giant rocket that's about to go from zero to 17,500 miles per hour? Or to look back on Earth from outer space and see the surprisingly precise line between day and night? Or to stand in front of the Hubble Space Telescope, wondering if the emergency repair you're about to make will inadvertently ruin humankind's chance to unlock the universe's secrets? Mike Massimino has been there, and in Spaceman he puts you inside the suit.

We would like to believe we can know things for certain. We want to be able to figure out who will win an election, if the stock market will crash, or if a suspect definitely committed a crime. But the odds are not in our favor. Life is full of uncertainty - indeed, scientific advances indicate that the universe might be fundamentally inexact - and humans are terrible at guessing. When asked to predict the outcome of a chance event, we are almost always wrong.

When was the last time you read a grand statement, accompanied by a large number and wondered whether it could really be true? Statistics are vital in helping us tell stories - we see them in the papers, on social media and we hear them used in everyday conversation - and yet we doubt them more than ever. But numbers - in the right hands - have the power to change the world for the better. Contrary to popular belief, good statistics are not a trick, although they are a kind of magic.

The Large Hadron Collider is the biggest, and by far the most powerful, machine ever built. A project of CERN, the European Organization for Nuclear Research, its audacious purpose is to re-create, in a 16.5-mile-long circular tunnel under the French-Swiss countryside, the immensely hot and dense conditions that existed some 13.7 billion years ago within the first trillionth of a second after the fiery birth of our Universe. The collider is now crashing protons at record energy levels never created by scientists before, and it will reach even higher levels by 2013.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Good to Go is the first definitive account of this new frontier in sports and exercise science. Christie Ashwanden takes you on a first-person tour through the science of exercise recovery, from ice baths and cryogenic freezing chambers to the science behind Usain Bolt’s love of chicken nuggets and Tom Brady’s recovery pyjamas.Full of eye-opening revelations, Aschwanden takes us on an invigorating journey through the science and potions of sports recovery and debunks the junk to give a clear picture of what we should actually be doing to achieve peak performance.

A journey through life, the universe and everything. From what actually happened in the big bang to the accidental discovery of Post-it notes, science is packed with surprising discoveries. Did you know, for instance, that if you were to get too close to a black hole it would suck you up like a noodle (it's called spaghettification), why your keyboard is laid out in QWERTY (it's not to make it easier to type) or whether the invention of the wheel was less important to civilisation than the bag (think about it)? New Scientist does.

This 10-part history of mathematics reveals the personalities behind the calculations: the passions and rivalries of mathematicians struggling to get their ideas heard. Professor Marcus du Sautoy shows how these masters of abstraction find a role in the real world and proves that mathematics is the driving force behind modern science.

The Physics Book sets out more than 80 key concepts and discoveries that have defined the subject and influenced our technology since the beginning of time. With the focus firmly on unpicking the thought behind each theory - as well as exploring when and how each idea and breakthrough came about - seven themed chapters examine the history and developments in areas such as energy and matter, and electricity and magnetism, as well as quantum, nuclear, and particle physics.

The idea that “thoughts become things” has become a meme in popular culture. It’s held as a firm proposition in metaphysics, and some spiritual teachers ascribe infinite powers to the mind. But are these claims scientifically accurate? What does the scientific evidence tell us about the scope of the human mind to transform thoughts into reality?

Go beyond the headlines and dive into the real science of the Large Hadron Collider. Each episode, your AI particle physicists Bob and Alice break down the latest, most significant papers from the LHC experiments at CERN. From new measurements of the Higgs boson to the ongoing search for physics beyond the Standard Model, this podcast offers a clear, expert review of cutting-edge research's data, methods, and implications. Perfect for physics students, researchers, and anyone who wants to understand the universe at its most fundamental level.

Quantum computing is advancing fast—and when it arrives, today’s encryption may fail. This practical guide by cybersecurity expert Taimur Ijlal helps you understand and prepare for the quantum threat before it hits.

We are a minuscule part of an incredible continuum: a chain of events spanning 13.8 billion years, with an infinite future. But what does that future hold? And will we ever truly understand our cosmic home? The Universe In a Box is Andrew Pontzen's tribute to simulation - the remarkable fusion of technology and science that, over the last century, has allowed us to understand the distant past and far future of the universe.

When leading Princeton physicist Paul Steinhardt began working in the 1980s, scientists thought they knew all the conceivable forms of matter. The Second Kind of Impossible is the story of Steinhardt’s 35-year-long quest to challenge conventional wisdom. It begins with a curious geometric pattern that inspires two theoretical physicists to propose a radically new type of matter - one that raises the possibility of new materials with never-before-seen properties but that violates laws set in stone for centuries.
