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.

This audiobook narrated by Juliet Stevenson shares the story of a world-renowned physicist who seeks gravity’s true nature and finds wisdom in embracing its force in her life.

Un aperçu lumineux et accessible de la recherche en physique quantique aujourd'hui. Le monde quantique Depuis le début du XXe siècle la physique quantique nous a révélé le monde étrange de l'infiniment petit. Dans celui-ci les certitudes de notre monde de tous les jours se brouillent. Les particules de matière ou de lumière n'y obéissent pas aux lois qui nous sont familières. A cette échelle microscopique, elles existent à la fois sous forme d'ondes et de particules, se manifestent simultanément dans des états différents, semblent être partout à la fois. Une nouvelle logique de la matière.

One of Scientific American’s Best Books of 2024 One of the world’s leading astrobiologists takes us on an awe-inspiring journey across the cosmos to investigate some of humanity’s most profound questions: Are we alone in the universe? And how did life on Earth begin? We are in a golden age...

“Now” is a simple yet elusive concept. You are reading the word “now” right now. But what does that mean? What makes the ephemeral moment “now” so special? Its enigmatic character has bedeviled philosophers, priests, and modern-day physicists from Augustine to Einstein and beyond...

More than 50 years ago, John Coltrane drew the 12 musical notes in a circle and connected them with straight lines, forming a five-pointed star. Inspired by Einstein, Coltrane had put physics and geometry at the core of his music. Physicist and jazz musician Stephon Alexander returns the favor, using jazz to answer physics' most vexing questions about the past and future of the universe.

Science is such a vast arena of knowledge that people looking for a better grasp of its secrets often wonder where to begin. The answer: with the essentials. Now, finally satisfy your desire for scientific inquiry in a way that makes this enormous field accessible, understandable, and undeniably captivating.

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike.

The basic principles that Bergson articulates, especially his way of thinking about reality as a dynamic process and his view of human beings as creative and evolving, should be helpful to anyone who seeks to go beyond simply dealing with the practical demands of daily life and consider the nature of things. Of special importance is Bergson’s claim that it is both possible and necessary to know from the inside rather than confining our attention to external perspectives and points of view. Intuition is able to get beyond what is relative and place us inside reality.

Weißt du, wie viel Sternlein stehen? Mehr als man sich vorstellen kann - und alle erzählen sie eine Geschichte über das Universum. Dank Gamma Draconis wissen wir, dass die Erde sich um ihre Achse dreht, und 61 Cygni hat uns verraten, wie große der Kosmos ist. Die Sterne nehmen uns mit auf die Suche nach außerirdischem Leben, erklären, wie schwarze Löcher funktionieren und warum die Dinosaurier ausgestorben sind. Und sie zeigen, wie wir durch den Weltraum reisen und andere Planeten besiedeln könnten.

Astronomers have recently discovered thousands of planets that orbit stars throughout the Milky Way. Much of what has captured the imagination of planetary scientists and the public is the unexpected strangeness of these distant worlds. The quest to find other worlds brims with possibility, and Donald Goldsmith presents the science of exoplanets and the search for extraterrestrial life in a way that even Earthlings with little to no background in astronomy or astrophysics can understand and enjoy.

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

In 1919, British scientists led extraordinary expeditions to Brazil and Africa to test Albert Einstein's revolutionary new theory of general relativity in what became the century's most celebrated scientific experiment. The result ushered in a new era and made Einstein a global celebrity by confirming his dramatic prediction that the path of light rays would be bent by gravity. Today, Einstein's theory is scientific fact. Yet the effort to "weigh light" by measuring the gravitational deflection of starlight during the May 29, 1919, solar eclipse has been clouded by myth and skepticism.

How math helps us solve the universe's deepest mysteriesOne of the great insights of science is that the universe has an underlying order. The supreme goal of physicists is to understand this order through laws that describe the behavior of the most basic particles and the forces between them...

A short and entertaining introduction to thermodynamics that uses real-world examples to explain accessibly an important but subtle scientific theory.

What is matter? Matter is the stuff from which we and all the things in the world are made. Everything around us - from desks, to books, to our own bodies - are made of atoms, which are small enough that a million of them can fit across the breadth of a human hair. Inside every atom is a tiny nucleus and orbiting the nucleus is a cloud of electrons. The nucleus is made out of protons and neutrons, and by zooming in further, you would find that inside each there are even smaller particles: quarks.

Bringing together the best and most interesting science stories appearing in Quanta Magazine over the past five years, Alice and Bob Meet the Wall of Fire reports on some of the greatest scientific minds as they test the limits of human knowledge. It communicates science by taking it seriously, wrestling with difficult concepts, and clearly explaining them in a way that speaks to our innate curiosity about our world and ourselves.

Les secrets de la matière et les premiers instants de l'univers. L'accélérateur de particules du CERN, le L.H.C., ('Large Hadron Collider'), est la machine la plus grande, la plus chère, la plus puissante jamais construite par l'homme. Son but est d'accélérer deux faisceaux de protons, (des constituants des noyaux atomiques), en sens inverse, et de les porter à une collision frontale. Les physiciens veulent étudier les produits de cette gigantesque collision. Pourquoi? On peut y répondre de deux façons.

What is electricity? Not just in theory, but really. What is it? Where did it come from? Who figured it out? How does it move, store, think, and shape the entire world? This isn’t a textbook. It’s the real story of how humans stumbled into one of the most powerful forces in nature and slowly, painfully, turned it into the thing that runs civilization.

Whether your interest lies in alternative cosmology, spiritual philosophy, or the intersection of science and metaphysics, this volume bridges those worlds. Walter Russell’s unified model demonstrates how mind and matter are inseparable aspects of one creative intelligence—revealing fresh insights for modern listeners.
