Physics

America’s favorite astrophysicist has written the most entertaining and universally appealing book of his stellar career: a practical guide for dealing with Alien visitors, an exploration of how it might happen, and a cultural history of our fascination with extraterrestrials. “Ever since...

A boundary-breaking astrophysicist reimagines the universe—and our place within it—in this audacious journey through the Nine Realms of the cosmos. The universe gave rise to everything: stars and cells, minds and memories, purpose and pain. But it doesn’t care about us. It follows its own...

A young queer millennial physicist unveils some of the most mind-bending physics concepts in the universe—and uses them to illuminate their own fascinating life story “I see physics everywhere,” Karmela Padavic-Callaghan writes. “It offers itself to me when I try to make sense of all the...

Der Materialismus stößt an seine erklärenden Grenzen. Geht man davon aus, dass es nur Materie, Energie und die Wechselwirkungen dazwischen gibt, bleiben Fragen unbeantwortet - zum Beispiel: Warum gibt es überhaupt Leben? Warum sind die Naturkonstanten so genau eingestellt...

This book challenges the centuries-old pursuit of a final theory in physics by revealing why reality resists scale-independent description. Drawing on developments in effective field theory, renormalization, and the philosophy of science, it argues that physical laws are not universal absolutes but layered tools adapted to context. With clarity and precision, it explores the limits of unification, the power of pragmatic models, and the intellectual maturity required to live with structural incompleteness.

We have long treated uncertainty as a flaw to be eliminated—a gap in knowledge, a defect in reality itself. But what if uncertainty is not optional—what if it is imperative? In this radical and rigorously argued book, Boris Kriger proposes The Law of Imperative Uncertainty: Any system capable of sustained complexity must permit exceptions to its laws in the form of persistent uncertainty and probabilistic deviation. A perfectly deterministic universe—closed, exceptionless, rigid—cannot endure.

For half a century, cosmology has relied on two invisible ingredients to explain the universe: dark matter, a substance that has never been detected despite decades of experimental search, and dark energy, a repulsive force whose physical nature remains entirely unknown. Together, they are said to constitute ninety-five percent of the cosmos. The remaining five percent—ordinary atoms, light, everything we have ever touched or measured—is treated as a minor addendum to a universe made mostly of darkness. This textbook presents a different cosmology. It is not speculative.

The universe is vast, silent, and filled with mysteries that continue to challenge everything we think we know. Strange Mysteries Of The Universe takes you on a fascinating journey through the most intriguing and unexplained phenomena of the cosmos —from the invisible matter holding galaxies together to the powerful gravity of black holes that bend space and time itself. This audiobook explores deep cosmic questions: What lies beyond the observable universe? Are parallel universes real? How do neutron stars survive in extreme conditions? And what does the future of the universe look like?

Menschen fliegen ins Weltall – das scheint uns inzwischen normal. In dieser Ausgabe von „Erzähl mir alles: Physik" beleuchten wir die Raumfahrt von Vergangenheit bis Zukunft, und von der kosmischen Nachbarschaft bis in die Ferne. Touristische Flüge an die Grenze des Weltalls, Langzeit-Aufenthalte auf Raumstationen, neue Flüge zum Mond oder Ende sogar eine Reise zu den Sternen: Egal, wohin es gehen soll, ohne Physik geht nichts!

Warum fühlt sich im Sommer eine Metallplatte viel heißer an als eine Holzplatte – auch wenn beide dieselbe Temperatur haben? Warum nehmen Fledermäuse Töne wahr, wo für uns alles still ist? Und ist das Rot, das ich sehe, dasselbe Rot, wie du es siehst? In unserem Kopf...
