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.

Are the physical laws of our universe finely tuned, such that life can exist? What does this imply about how our universe formed? Questions like these are examined in Nature's Balancing Act, presented for a wide audience.

Erika Hamden, a renowned astrophysicist and educator, brings her passion for space to life in this engaging book. With years of experience studying the cosmos, Hamden specializes in making complex topics fun and easy to understand.

Whether your interest lies in alternative cosmology, spiritual philosophy, or the intersection of science and metaphysics, this volume bridges those worlds.

Né en 1944 à Casablanca, Serge Haroche a fait ses études à l'Ecole Normale Supérieure (ENS). Il a été chercheur au CNRS, Maître de Conférences à l'Ecole Polytechnique, Professeur à l'Université Paris VI et membre de l'Insitut de France. Il a enseigné pendant plusieurs années à l'Université de Yale, aux Etats-Unis et visité, comme chercheur ou professeur invité, plusieurs universités étrangères dont Stanford, Harvard, MIT et l'Université fédérale de Rio de Janeiro. Il a dirigé pendant cinq ans le département de Physique de l'ENS.Serge Haroche est un spécialiste de la ...

Why is gravity the only force that refuses to play by the rules? In this deep dive, we explore the history and current status of the search for a "Theory of Everything"—the holy grail of physics that aims to unify Einstein’s General Relativity with Quantum Mechanics. This series takes you to the frontlines of the battle between the two biggest contenders: String Theory and Loop Quantum Gravity. We explain why the "Graviton" is the most elusive particle in the universe, why gravity is so shockingly weak, and whether we might be wrong about the fundamental nature of reality.

Bevor Sie sich jedoch in dieses magische und faszinierende Abenteuer stürzen, möchte ich Ihnen erklären, warum dieses Buch Ihr Leben fast automatisch und auf eine Art und Weise verändern wird, die all Ihre Bedürfnisse erfüllt, ohne dass Sie es überhaupt bemerken.

In this audiobook, Dr Kruszelnicki takes us on another exploration of the dazzling world of science. Does cranberry juice cure urinary tract infections? Is the hookah really a safer way to smoke? Will the Large Hadron Collider destroy the Earth and the Universe?

Black holes are some of the most fascinating phenomena in the natural universe. In this beautiful pocket volume, Odenwald explores the science behind black holes in simple and accessible language. He explains what black holes are, how they come into existence, and how they affect the universe around us. Taking into consideration subjects such as gravity, quantum mechanics, the holographic principle and thermodynamics along the way, The Essential Book of Black Holes provides the perfect starting point for anyone interested in the subject.

Finding the right tools and strategies to effectively teach physics is challenging! Should I lecture? How should I do labs? What if their math skills are weak? What if they bombed the last test? How do I know they’re even learning??Luckily, there are researchers out there studying best practices for teaching and learning physics. As I learn these things myself and practice them in my own dual enrollment physics classroom, I want to share these evidence-based insights with you.Not only that, but over 50% of physics teachers in the US did not major in physics! If that’s you, I want to help ...

Wir reisen zu den entlegensten Orten des Alls: zur ISS, zum Mars, zu Kometen, Schwarzen Löchern und Sternenstaub. Mit Originalaufnahmen von Astronaut:innen erleben wir Raumfahrt, Forschung und Philosophie zwischen Erde und Unendlichkeit.

Brought to you by Penguin. In this exhilarating and sometimes mind-bending book, renowned scientist and author Paul Davies tells the gripping story of how, beginning with an iconic mathematical equation in the 1920s, a radical new theory of nature – quantum mechanics – burst upon the modern...

How do you introduce something so groundbreaking and new, yet also so ancient that it deals with the very first moments of Creation? Most people know about the 22 letters of the Hebrew Alphabet, and many have studied a bit of quantum theory. However, one thing has been missing that has to do with the divine language of Eden and the reset back to Eden and beyond.

This book invites you on a journey through the most misunderstood concept in all of science — the vacuum. From the earliest philosophers terrified of emptiness to the modern physicists who discovered that “nothing” is a swirling ocean of energy and possibility, this is the story of how the void became the foundation of everything. We begin with the ancient debates about ether and the first laboratory vacuums of the Renaissance, then move through Einstein’s curved spacetime, quantum field theory’s restless vacuum, and the mysterious Higgs field that gives matter its mass.

At the center of our Milky Way lies one of the most extraordinary and enigmatic objects in the Universe — Sagittarius A *, a supermassive black hole four million times more massive than the Sun. Invisible to the human eye yet governing the motion of stars and gas across tens of thousands of light-years, it is both a gravitational anchor and a cosmic mystery. In A Hungry Giant in the Heart of Our Galaxy, science writer and philosopher Boris Kriger takes readers on a journey through three decades of discovery at the frontiers of astrophysics.

Gravity is at once familiar and mysterious. It's the reason for the numbers on your bathroom scale, the intricate dance of the stars and planets, and the evolution and eventual fate of the universe. In Crush, James Riordon takes listeners on a tour of gravity from its vanishing insignificance on the microscopic scale to its crushing extreme inside black holes.

Physics helps us understand how the world works. Philosophy asks why it matters. Inertia dives into their intersection, exploring the mechanics of reality and burning questions at the forefront of current academia. Each episode tackles one central question - but sprawls out into topics dating back centuries of persistent societal ideologies, all to better understand the tangled web of phenomena that makes up our universe. Whether you’re a science person, humanities person, or both - these mind-bending ideas and controversial theories will keep you thinking long after you finish these ...
