Drawing on troves of declassified files, including records released by the government for the first time through the author's efforts, Restricted Data traces the complex evolution of the US nuclear secrecy regime from the first whisper of the atomic bomb through the mounting tensions of the Cold War and into the early 21st century. A compelling history of powerful ideas at war, it tells a story that feels distinctly American: rich, sprawling, and built on the conflict between high-minded idealism and ugly, fearful power.

The Chernobyl Disaster, which occurred in late April 1986, was the worst nuclear accident in history. It not only caused widespread radioactive contamination, but even more importantly, it claimed many lives and caused panic worldwide about the safety of nuclear power. In short, it changed the face of nuclear energy globally.

Physics informs our understanding of how the world works - but more than that, key breakthroughs in physics have transformed everyday life. We journey back to 10 separate days in history to understand how particular breakthroughs were achieved, meet the individuals responsible and see how each breakthrough has influenced our lives.

Ours is the age of global warming. Rising sea levels, extreme weather, forest fires. Climate scientist Peter Stott reveals the bitter fight to get international recognition for what, among scientists, has been known for decades: human activity causes climate change. Across continents and against the efforts of sceptical governments, prominent climate change deniers and shadowy lobbyists, Hot Air is the urgent story of how the science was developed, how it has been repeatedly sabotaged and why humanity hasn't a second to spare in the fight to halt climate change.

Pourquoi y a-t-il des atomes, des planètes et des humains plutôt que rien ? Comment pouvons-nous aimer, créer, croire, agir, penser... alors que notre cerveau est le fruit des lois déterministes de la physique ? La conscience est-elle apparue par la seule grâce du hasard ? Et si les étoiles sont appelées à terme à se consumer, les galaxies à se disperser et les trous noirs à s'évaporer comme l'a prédit Stephen Hawking, quel sens donner à notre existence ?

Centuries ago, the principle of Ockham’s razor changed our world by showing simpler answers to be preferable and more often true. In Life Is Simple, scientist Johnjoe McFadden traces centuries of discoveries, taking us from a geocentric cosmos to quantum mechanics and DNA, arguing that simplicity has revealed profound answers to the greatest mysteries. This is no coincidence. From the laws that keep a ball in motion to those that govern evolution, simplicity, he claims, has shaped the universe itself.

¿Qué es la física cuántica? ¿Conoces los misterios más grandes del Universo? La física cuántica es, de todas las teorías científicas, la que quizás más verificaciones y contrastaciones ha recibido al mismo tiempo, y a la vez la más determinante para la vida que llevamos en el siglo XXI. El término “cuántica” proviene de “quantum”, que es la unidad más pequeña que conforma la luz. La física cuántica nos enseña que más allá de todo lo que es material y palpable hay energía.

Physicist and popular science author Simon Singh explores the numbers and concepts that lie at the heart of some of the trickiest problems in mathematics, revealing their history, significance and unique qualities. Beginning with zero - which, amazingly, wasn't invented until 400 BC and then took thousands of years to catch on - he goes on to serve up a slice of pi, uncover the hidden beauty of the Golden Ratio, reveal the reality behind the imaginary number and explain why some infinities are bigger than others.

Le temps s'écoule-t-il toujours à la même vitesse ? D'où vient la gravité ?Comment notre Univers est-il né ? Est-il infini ? À quoi ressemble un trou noir ?Autant de questions vertigineuses qui ont occupé les esprits les plus brillants, de Galilée à Einstein en passant par Newton. Ce livre audio vise à les décrypter et à raconter la théorie de la relativité de manière ludique, en s'appuyant sur des explications et illustrations accessibles à tous.

One of the world’s most prominent physicists and fearless free spirit, Carlo Rovelli is also a masterful storyteller. His bestselling books have introduced millions of readers and listeners to the wonders of modern physics and his singular perspective on the cosmos. This new collection of essays reveals a curious intellect always on the move. Rovelli invites us on an accessible and enlightening voyage through science, literature, philosophy, and politics.

A Brief Welcome to the Universe offers a breathtaking tour of the cosmos, from planets, stars, and galaxies to black holes and time loops. Best-selling authors and acclaimed astrophysicists Neil deGrasse Tyson, Michael A. Strauss, and J. Richard Gott take listeners on an unforgettable journey of exploration to reveal how our universe actually works. Propelling you from our home solar system to the outermost frontiers of space, this book builds your cosmic insight and perspective through a marvelously entertaining narrative.

En 1916, Einstein predijo la existencia de ondas gravitacionales, su máxima prioridad después de proponer su teoría del espacio-tiempo curvo. Un siglo después, estamos grabando los primeros sonidos del espacio, evidencia de la existencia de las ondas causadas por la colisión de dos agujeros negros. Es la banda sonora que acompaña a la película muda de la astronomía. Janna Levin relata la ambición experimental que comenzó como un divertido experimento mental y se convirtió en objeto de obsesión para los arquitectos originales de la idea: Rai Weiss, Kip Thorne y Ron Drever.

Histories of science in the 20th century have focused on relativity and quantum mechanics. But, quietly in the background, there has been a third area of exploration that has equally important implications for our understanding of the universe. It is unknown to the general public, despite the fact that many Nobel prize winners, senior academics and major research centres around the world have been devoted to it - it is the study of plasma.

After a long and productive life, you lay upon your deathbed. As you take your last breath, the last remnant of your intelligence and thought passes from your brain into the surrounding ambience of the room…and beyond. This author will explain how death is just the beginning of a new, grand existence for this former spark of life. Quantum physics and science define this new reality…not religion.

La ciencia ficción nos permite visitar lugares que sólo podemos soñar ver: otros mundos, estrellas lejanas, galaxias enteramente nuevas. No todos los relatos se ocupan de la ciencia real que hay detrás de los viajes espaciales y otras empresas futuristas, pero la ficción puede ofrecer una perspectiva asombrosa de hasta dónde podrían llegar nuestras capacidades y de lo que soñamos con hacer.

Whether you believe it or not, the quantum world is real! Quantum physics discovers the behavior of energy and matter at the nuclear, atomic, molecular, and even smaller levels. This book will make such a complicated subject simple to comprehend. It avoids the complicated math and jumps right into all the implications, thought experiments, paradoxes, and concepts that make quantum physics so intriguing to people out there.

Are we on the brink of discovering the first ever evidence that aliens exist? Join astronomer Professor Alan Duffy on his search to answer this question, as he speaks to a new generation of alien hunters embarking on the greatest hunt for extraterrestrials that’s ever been undertaken.

The author, Chris McMullen, PhD, has over 20 years of experience teaching math skills to physics students. He prepared this workbook of the Improve Your Math Fluency series to share his passion for word problems. This book includes 200 word problems with answers.

In The Quantum Universe, Brian Cox and Jeff Forshaw approach the world of quantum mechanics in the same way they did in Why Does E=mc2? and make fundamental scientific principles accessible - and fascinating - to everyone.The subatomic realm has a reputation for weirdness, spawning any number of profound misunderstandings, journeys into Eastern mysticism, and woolly pronouncements on the interconnectedness of all things. Cox and Forshaw's contention? There is no need for quantum mechanics to be viewed this way.
