From the New York Times best-selling author of Seven Brief Lessons on Physics, The Order of Time, and Helgoland, a closer look at the mind-bending nature of the Universe. What are the elementary ingredients of the world? Do time and space exist? And what exactly is reality? Theoretical physicist Carlo Rovelli has spent his life exploring these questions. He tells us how our understanding of reality has changed over the centuries and how physicists think about the structure of the Universe today.

Over two millennia ago, the prescient insights of Anaximander paved the way for cosmology, physics, geography, meteorology, and biology, setting in motion a new way of seeing the world. His legacy includes the revolutionary ideas that the Earth floats in a void, that animals evolved, that the world can be understood in natural rather than supernatural terms, and that universal laws govern all phenomena. In this elegant work, the renowned theoretical physicist Carlo Rovelli brings to light the importance of Anaximander’s overlooked influence on modern science

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. We slip beyond its horizon and tumble down this crack in the universe. As we plunge, we see geometry fold. Time and space pull and stretch. And finally, at the black hole’s core, space and time dissolve, and a white hole is born. Rovelli has dedicated his career to uniting the time-warping ideas of general relativity and the perplexing uncertainties of quantum mechanics. In White Holes, he reveals the mind of a scientist at work.

One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the 23-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution.

Dans ses "Sept brèves leçons de physique", Carlo Rovelli confiait : qu'une question avait guidé sa vie de chercheur : la nature du temps. Se hissant sur les épaules d'Isaac Newton, d'Albert Einstein, de Stephen Hawking et de bien d'autres, il nous livre enfin ses découvertes dans ce livre majeur. Le temps est au cœur d'un étrange mystère. Tel un flocon de neige qui fond lorsqu'on s'en saisit, il s'est progressivement délité sous les assauts de la science : on sait dorénavant que le temps s'écoule plus lentement en plaine qu'en altitude.

One of the world’s most prominent physicists and fearless free spirit, Carlo Rovelli is also a masterful storyteller. His bestselling books have introduced millions of readers and listeners to the wonders of modern physics and his singular perspective on the cosmos. This new collection of essays reveals a curious intellect always on the move. Rovelli invites us on an accessible and enlightening voyage through science, literature, philosophy, and politics.

In lyric, accessible prose, Carlo Rovelli invites us to consider questions about the nature of time that continue to puzzle physicists and philosophers alike. For most listeners, this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it appears. We think of it as uniform and universal, moving steadily from past to future, measured by clocks. Rovelli tears down these assumptions one by one, revealing a strange universe where, at the most fundamental level, time disappears.

This playful, entertaining, and mind-bending introduction to modern physics briskly explains Einstein's general relativity, quantum mechanics, elementary particles, gravity, black holes, the complex architecture of the Universe, and the role humans play in this weird and wonderful world. Carlo Rovelli, a renowned theoretical physicist, is a delightfully poetic and philosophical scientific guide. He takes us to the frontiers of our knowledge: To the most minute reaches of the fabric of space, back to the origins of the cosmos, and into the workings of our minds.

Esprit libre, scientifique de renom, curieux de philosophie et d'humanités, Carlo Rovelli est aussi un formidable conteur. Sa curiosité l'amène à s'interroger sur le monde qui nous entoure, sur la nature du temps qui passe, et jusqu'aux grandes questions philosophiques aux réponses incertaines. Il rassemble ses réflexions dans ces Écrits vagabonds.

Mistero per profani e scienziati, la natura del tempo è l'oggetto di questo libro sorprendente. Un racconto delle diverse strade intraprese nel corso dei secoli per comprendere ciò di cui tutti facciamo esperienza in ogni istante. Un viaggio illuminante a partire da Anassimandro, passando per Newton e Einstein, fino ad arrivare alle più recenti teorie sulla gravità a loop e ad affacciarsi sul "grande oceano notturno e stellato di quello che ancora non sappiamo".

Una guida per tutti attraverso le rivoluzioni scientifiche che hanno sconvolto la fisica nel ventesimo secolo. Con folgorante chiarezza vengono qui spiegate la teoria della relatività generale di Einstein, la meccanica quantistica, i buchi neri, la complessa architettura dell'universo, le particelle elementari, la gravità e la natura del tempo e della mente: una limpida e divertente introduzione a quelle scoperte della fisica contemporanea che smentiscono ogni nostra percezione e intuizione immediata.

“Da qualche anno la mia ricerca si è concentrata sui buchi bianchi, elusivi fratelli minori dei buchi neri. Questo è il mio libro sui buchi bianchi. Provo a raccontare come sono fatti i buchi neri, che vediamo nel cielo a centinaia. Cosa accade sul bordo di queste strane stelle, l’orizzonte, dove il tempo appare rallentare fino a fermarsi e lo spazio sembra strapparsi. Poi giù, dentro, nelle regioni più interne, fin dove tempo e spazio si sciolgono. Fin dove è come rimbalzare indietro nel tempo. Fin dove nascono i buchi bianchi.”

"Von Natur aus wollen wir immer mehr wissen und immer weiter lernen. Unser Wissen über die Welt wächst. Uns treibt der Drang nach Erkenntnis und lernend stoßen wir an Grenzen. In den tiefsten Tiefen des Raumgewebes, im Ursprung des Kosmos, im Wesen der Zeit, im Schicksal der Schwarzen Löcher und im Funktionieren unseres eigenen Denkens. Hier, an den Grenzen unseres Wissens, wo sich das Meer unseres Nichtwissens vor uns auftut, leuchten das Geheimnis der Welt, die Schönheit der Welt, und es verschlägt uns den Atem.", schreibt Carlo Rovelli.

Vorwärts in die Vergangenheit. Weiße Löcher sind das Gegenteil von Schwarzen Löchern – sie sind vermutlich ihre Abkömmlinge. Die einen ziehen alle Materie unwiderstehlich in sich hinein, die anderen geben ihre Information wieder frei. Sie sind ein weiteres großes Rätsel der Kosmologie, und noch gibt es keinen Beweis ihrer Existenz. Einsteins Gleichungen lassen sie aber vermuten, und mit Carlo Rovellis Quantentheorie sind Weiße Löcher theoretisch darstellbar.

Inesperado best seller en Italia, con traducciones a más de veinte idiomas, Siete breves lecciones de física se ha convertido en un éxito bien sencillo de explicar por algo muy difícil de conseguir: con pasión, fluidez y una encomiable voluntad de presentar de un modo diáfano temas complejos, Carlo Rovelli, científico de estirpe humanista, nos propone un breve pero muy completo recorrido por los hitos de la física de los últimos cien años en siete lecciones magistrales.
