المادَّة هي المكوِّن الأساسي للكون. ونحن نعرف الذرَّة جيداً وأنها جُسيم شديد الصِّغر لدرجة أن شعرة الإنسان الرفيعة قد تتَّسع لمليون ذرَّة. إلا أن المادَّة بحرٌ أوسع من هذا بكثير، وفَـهْـم طبيعتها عملية دؤوبة لا تنتهي. يستكشف «جيف كوتريل» خبايا جميع أشكال المادَّة، بدايةً من أشكالها المألوفة مثل المواد الصلبة والسائلة والغازيَّـة، وحتى البلازما والأشكال غير المألوفة، مثل المادَّة الكميَّـة والمادَّة المضادَّة. يستعرض كوتريل كذلك نشأة المادَّة في الانفجار العظيم، فيتحدَّث عن تكوين الذرَّة والطاقة والكتلة والأشكال الغامضة للمـادَّة المظلمة والطاقة المظلمة، فيتضح لنا أننا ما زلنا لا نعلم الكثير عن المادَّة التي يتكوَّن منها عالمنا.

Welcome to the aerospace informer! a global club where we discover the wonders of aerospace and how planes and rockets work!

From the best-selling author of Seven Brief Lessons on Physics comes a new audiobook about the mind-bending nature of the universe. What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries.

Discover how to tap into your extraordinary human capacity for connection and healing using astonishing new findings about the miraculous power of group intention in this new book by the author of the international bestsellers The Intention Experiment and The Field. In The Power of Eight, Lynne...

The Pleasure of Finding Things Out is a magnificent treasury of the best short works of Richard P. Feynman, from interviews and speeches to lectures and printed articles. A sweeping, wide-ranging collection, it presents an intimate and fascinating view of a life in science - a life like no other. From his ruminations on science in our culture to his Nobel Prize acceptance speech, this book will delight anyone interested in the world of ideas.

Experimental physicist at CERN and acclaimed science presenter Harry Cliff offers an eye-opening account of the inexplicable phenomena that science has only recently glimpsed, and that could transform our understanding of the fundamental nature of reality. Something strange is going on in the...

"Science does not need mysticism and mysticism does not need science, but man needs both." —Fritjof Capra, Ph.D. Their paths to the truth could not be more different—but the amazing thing is that, in their own ways, the mystics and the scientists are discovering the same truths about our...

Gene Kranz was present at the creation of America's manned space program and was a key player in it for three decades. As a flight director in NASA's Mission Control, Kranz witnessed firsthand the making of history. He participated in the space program from the early days of the Mercury program to the last Apollo mission, and beyond. He endured the disastrous first years when rockets blew up and the United States seemed to fall further behind the Soviet Union in the space race.

L'essentiel à connaître sur la physique quantique ! Beaucoup d'entre nous ignorent à quoi la physique quantique renvoie précisément : d'où vient le terme " quantique " ? Quand cette science a-t‑elle vu le jour ? Pourquoi doit-on la distinguer de la physique classique ? En 50 notions, Blandine Pluchet vous emmène à travers un fascinant voyage au coeur de l'infiniment petit. Grâce aux découvertes de physiciens du xxe siècle tels que Planck, Einstein ou encore Bohr, quanta, photons, électrons et autres composants de la matière n'auront bientôt plus de secrets pour vous !

In Neil deGrasse Tyson’s delightful journey through the cosmos, his fictional character Merlin responds to popular questions asked by adults and children alike. Merlin, a timeless visitor from Planet Omniscia in the Andromeda Galaxy, has observed firsthand many of the major scientific events of Earth’s history.

Albert Einstein described Relativity as a "popular explosion" of his famous theory. Written in 1916, it introduced the lay audience to the remarkable perspective which had overturned theoretical physics. Einstein's genius was to express this perspective in understandable terms.

In Waves in an Impossible Sea, physicist Matt Strassler tells a startling tale of elementary particles, human experience, and empty space. He begins with a simple mystery of motion. When we drive at highway speeds with the windows down, the wind beats against our faces. Yet our planet hurtles through the cosmos at 150 miles per second, and we feel nothing of it. How can our voyage be so tranquil when, as Einstein discovered, matter warps space, and space deflects matter? The answer, Strassler reveals, is that empty space is a sea, albeit a paradoxically strange one.

The Man Who Mastered Gravity is an intimate profile of Thomas Townsend Brown, a little-known scientist whose unorthodox ideas about electricity and gravity have made him the subject of decades of speculation and intrigue. Brown developed his novel concepts while serving in the U.S. Navy through the 1930s. In the first months of World War II he was abruptly discharged–despite his expertise in radio, radar, and mine sweeping.

The grid is an accident of history and of culture, in no way intrinsic to how we produce, deliver and consume electrical power. Yet this is the system the United States ended up with, a jerry-built structure now so rickety and near collapse that a strong wind or a hot day can bring it to a grinding halt. The grid is now under threat from a new source: renewable and variable energy, which puts stress on its logics as much as its components.

Award-winning science journalist and author Lynne McTaggart invites listeners to take part in the world's largest mind-over-matter experiment in The Intention Experiment. By thinking positively about life and consciousness, people can, in fact, change their lives.

"The Universal One" by Walter Russell is an ambitious and comprehensive work that endeavors to blend the realms of science, philosophy, and spirituality into a singular, cohesive theory of the universe.

Light of the Stars is science at the grandest of scales, and it tells a radically new story about what we are: one world in a universe awash in planets. Building on his widely discussed scientific papers and New York Times op-eds, astrophysicist Adam Frank shows that not only is it likely that alien civilizations have existed many times before, but also that many of them have driven their own worlds into dangerous eras of change.

"This is science writing as wonder and as inspiration." —The Wall Street Journal Wall Street Journal From one of the most influential scientists of our time, a dazzling exploration of the hidden laws that govern the life cycle of everything from plants and animals to the cities we live in...

In a universe filled by chaos and disorder, one physicist makes the radical argument that the growth of order drives the passage of time - and shapes the destiny of the universe.

Fans of xkcd ask Munroe a lot of strange questions: What if you tried to hit a baseball pitched at ninety percent the speed of light? How fast can you hit a speed bump while driving and live? If there was a robot apocalypse, how long would humanity last? What if everyone only had one soulmate? What would happen if the moon went away? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations, and consults with nuclear reactor operators.
