Physics

Die Lage scheint klar: Drei Dimensionen hat unsere Welt! Alles, was wir sehen, greifen, fühlen hat eine Breite, eine Höhe und eine Tiefe. Aber stimmt das wirklich? Oder lauert hinter der nächsten Ecke noch eine vierte oder sogar fünfte Dimension, unsichtbar für unsere beschränkte Wahrnehmung? In dieser Ausgabe von "Erzähl mir alles – Physik" schauen wir ganz genau nach in Raum und Zeit.

By most popular accounts, the universe started with a bang some 13.8 billion years ago. But what happened before the Big Bang? And how do we know it happened at all? Here prominent cosmologist Niayesh Afshordi and science communicator Phil Halper offer a tour of the peculiar possibilities...

As a fundamental particle, the electron is central to an understanding of the nature of matter. All of chemistry is dependent on the interaction of electrons on the outside of atoms. But the electron has also become increasingly central to our lives, first through the deployment of electricity...

FOR NON-EXPERTS: Get an accessible introduction to quantum computing as a mathematician explains quantum algorithms, quantum entanglement, and more. Quantum computing is a beautiful fusion of quantum physics and computer science!

In 100 AD, Plutarch wrote what would become the first science fiction about the civilisation on the moon, appended to a rigorous scientific analysis of current knowledge about the moon. Orbital mechanics, optics, atmospheric refraction, lunar geography, planetary and stellar composition...

What astronauts' extraordinary experiences of awe and humility teach us about humanity. What is it like to stand in the shadow of Earth and the Moon and look out at the vastness of the Milky Way? To confront a view so grand it cannot be reproduced in a photo? These are the questions space...

Kaum ein anderer lebender Naturwissenschaftler besitzt die Fähigkeit, mit solcher Geistesklarheit die tiefsten Einsichten der modernen Quantenphysik mit dem uralten spirituellen Menschheitswissen zu verknüpfen wie Hans-Peter Dürr! Es gelingt Dürr scheinbar mühelos, eine Synthese zwischen den meditativen Einsichten der Weisen des Ostens und den aktuellen Erkenntnissen der modernen Naturwissenschaften herzustellen. Dabei verliert er sich niemals in langatmigen akademischen Erläuterungen, sondern hat stets den Menschen und die gesellschaftliche Wirklichkeit des 21. Jahrhunderts im Blick.

Look up at the night sky. Every star, every galaxy, every wisp of nebula appears perfectly, eternally still. The constellations that Hipparchus cataloged over two thousand years ago remain recognizable tonight. The Universe seems frozen. It is not. Behind that apparent stillness rages a cosmos of extraordinary violence: galaxies colliding over hundreds of millions of years, stars being born and dying in thermonuclear cataclysms, space itself expanding and carrying everything apart. The Universe is not frozen. We are merely too brief to see it move.

Universe 25 meets quantum physics. In 1968, behavioral researcher John B. Calhoun built a perfect world for mice. Unlimited food, unlimited water, no predators, no disease. Paradise. The mice thrived at first. They bred, built social groups, and formed a functioning colony. Then everything fell apart. Males became violent without reason. Females abandoned their young. A group Calhoun called the beautiful ones withdrew completely, spending their days grooming themselves in isolation while their world crumbled around them. Reproduction stopped. Social bonds dissolved. Every single mouse died.

Dive into the groundbreaking work of Thomas Louis Navarro as he redefines propulsion with the 4-Phase Motor Generator Device. Drawing from advanced electromagnetic engineering and supersymmetric design, this book introduces a revolutionary concept: using eccentric mass loads and the Higgs Field to move payloads in space—without traditional fuel-based thrust.

Подобные заголовки часто встречаются в прессе. В них не было бы большой беды, если бы из-за порождаемых мифов не формировалось конспирологическое мировоззрение, отрицающее историю космонавтики и достижения науки. Космическую мифологию легко опровергнуть фактами, но чтобы добраться до них, нужны знания и опыт. Книга Антона Первушина, писателя и научного журналиста, поможет сориентироваться в потоках информации и научиться отделять правду от вымысла.

Квантовая механика — самый точный из известных человечеству способов описания мира на той фундаментальной глубине, которая определяет его структуру, но недоступна прямому наблюдению. Только благодаря квантовой природе удается существовать атомам, людям, звездам и почти всему остальному. На заре второго квантового столетия Алексей Семихатов предлагает последовательное изложение современного состояния квантовой механики.

The first book in this series, The End of Dark Cosmology, showed that ninety-five percent of the universe does not need to be missing. One conceptual correction—separating the cosmological constant from the energy of the quantum vacuum—reproduced the successes of dark matter and dark energy without invoking either. The coupling constant was derived from measured nuclear physics. Zero free parameters. No new particles. No new forces. This book takes the same formula and pushes it to its logical extremes.
