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.

Whether pondering black holes or predicting discoveries at CERN, physicists believe the best theories are beautiful, natural, and elegant, and this standard separates popular theories from disposable ones. This is why, Sabine Hossenfelder argues, we have not seen a major breakthrough in the foundations of physics for more than four decades. The belief in beauty has become so dogmatic that it now conflicts with scientific objectivity: Observation has been unable to confirm mindboggling theories, like supersymmetry or grand unification, invented by physicists based on aesthetic criteria.

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.

Are you fascinated by the cosmos and eager to explore the quantum realm without complex equations? Curious about wave-particle duality or how quantum theories impact everyday life, from computing to futuristic tech? Quantum Physics Simplified breaks down mind-bending concepts into engaging, easy-to-follow explanations, making the quantum world accessible to anyone with a curious mind.

By 100 years ago, it seemed clear that the speed of light was the fastest possible speed. Causality was safe. And then quantum mechanics happened, introducing spooky connections that seemed to circumvent the law of cause and effect. From Aristotle's Physics to quantum teleportation, learn about the scientific pursuit of instantaneous connections in this insightful examination of our world.

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.

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?

Every physicist agrees quantum mechanics is among humanity's finest scientific achievements. But ask what it means, and the result will be a brawl. For a century, most physicists have followed Niels Bohr's solipsistic and poorly reasoned Copenhagen interpretation. Indeed, questioning it has long meant professional ruin, yet some daring physicists, such as John Bell, David Bohm, and Hugh Everett, persisted in seeking the true meaning of quantum mechanics. What Is Real? is the gripping story of this battle of ideas and the courageous scientists who dared to stand up for truth.

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.
