If you move at high speed, time slows down, space squashes up, and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing - and live forever! As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity.

Time rules our lives, woven into the very fabric of the universe-from the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day. Nothing so pervades our existence and yet is so difficult to explain. But now, in a series of 24 riveting lectures, you can grasp exactly why - as you take a mind-expanding journey through the past, present, and future, guided by a noted author and scientist.

A brilliantly original and richly illuminating exploration of entanglement, the seemingly telepathic communication between two separated particles - one of the fundamental concepts of quantum physics.

In this 12-lecture masterpiece of scientific reporting, you'll learn everything you need to know to fully grasp the significance of this discovery, including the basics of quantum mechanics; the four forces that comprise the Standard Model of particle physics; how these forces are transmitted by fields and particles; and the importance of symmetry in physics.

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?

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.

Read by the author, Harry Cliff. 'As fascinating as its title suggests . . . Cliff recounts with vivid clarity the stories of some of the most striking oddnesses that have lit up the landscape of modern physics.' – Philip Pullman Newly discovered strangenesses could transform our understanding...

What's going on in the sky? Astronomy For Dummies takes you through the solar system, the Milky Way galaxy, and all the way to the outer reaches of the universe. You'll have stars in your eyes as you discover the basics of skywatching, planets, asteroids, black holes, and dark matter. Ponder the deep questions that keep humanity guessing, like, is there anybody out there? Two NASA-award-winning astronomers take you on a tour of outer space that will fascinate you—and, if you're a student, help you through your intro astronomy course.

Over the last 220 years, society has evolved a universal belief that electricity is "safe" for humanity and the planet. Scientist and journalist Arthur Firstenberg disrupts this conviction by telling the story of electricity in a way it has never been told before - from an environmental point of view - by detailing the effects that this fundamental societal building block has had on our health and our planet.

In Cosmos, the late astronomer Carl Sagan cast his gaze over the magnificent mystery of the Universe and made it accessible to millions of people around the world. Now in this stunning sequel, Carl Sagan completes his revolutionary journey through space and time.

初学者納得、玄人脱帽！読めば腑に落ちる。使えば役に立つ。力学の裏にある美しい構造が見えてくる。一歩ずつ丁寧に、基礎から記述した入門書。ラグランジアンもハミルトニアンも「ありがたみ」からきちんとわかる。

There was a time when “universe” meant all there is. Everything. Yet, in recent years discoveries in physics and cosmology have led a number of scientists to conclude that our universe may be one among many. With crystal-clear prose and inspired use of analogy, Brian Greene shows how a range of different “multiverse” proposals emerges from theories developed to explain the most refined observations of both subatomic particles and the dark depths of space.

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?

Classical physics is about how things move, why they move, and how they work. It's about making sense of motion, gravity, light, heat, sound, electricity, and magnetism, and seeing how these phenomena interweave to create the rich tapestry of everyday experience. It is, in short, the hidden order of the universe.

This audio edition is narrated with dazzling enthusiasm by the author, Dr Becky Smethurst. Right now, you are orbiting a black hole. The Earth orbits the Sun, and the Sun orbits the centre of the Milky Way: a supermassive black hole, the strangest and most misunderstood phenomenon in the galaxy...

The millions of people around the world who loved What If? still have questions, and those questions are getting stranger. Thank goodness xkcd creator Randall Munroe is here to help. Planning to ride a fire pole from the Moon back to Earth? The hardest part is sticking the landing. Hoping to cool the atmosphere by opening everyone’s freezer door at the same time? Maybe it’s time for a brief introduction to thermodynamics. Want to know what would happen if you rode a helicopter blade, made a lava lamp out of lava, or jumped on an erupting geyser? Okay, if you insist.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution.

In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell--and what the origin of life some four billion years ago can tell us about the process of technological innovation today.

Already internationally acclaimed for his elegant, lucid writing on the most challenging notions in modern physics, Sean Carroll is emerging as one of the greatest humanist thinkers of his generation as he brings his extraordinary intellect to bear not only on the Higgs boson and extra dimensions but now also on our deepest personal questions. Where are we? Who are we? Are our emotions, our beliefs, and our hopes and dreams ultimately meaningless out there in the void?

It was Richard Feynman's outrageous and scintillating method of teaching that earned him legendary status among students and professors of physics. From 1961 to 1963, Feynman delivered a series of lectures at the California Institute of Technology that revolutionized the teaching of physics. In Six Not-So-Easy Pieces, taken from these famous Lectures on Physics, Feynman delves into one of the most revolutionary discoveries in twentieth-century physics: Einstein's theory of relativity.
