Time is a mystery that does not cease to puzzle us. Philosophers, artists and poets have long explored its meaning while scientists have found that its structure is different from the simple intuition we have of it. From Boltzmann to quantum theory, from Einstein to loop quantum gravity, our understanding of time has been undergoing radical transformations. Time flows at a different speed in different places, the past and the future differ far less than we might think, and the very notion of the present evaporates in the vast universe.

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.

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.

In June 1925, 23-year-old Werner Heisenberg, suffering from hay fever, retreated to a small, treeless island in the North Sea called Helgoland. It was there that he came up with one of the most transformative scientific concepts: quantum theory. Almost a century later, quantum physics has given us many startling ideas: ghost waves, distant objects that seem magically connected to each other, cats that are both dead and alive. Today our understanding of the world around us is based on this theory. And yet it is still profoundly mysterious.

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.

Penguin presents the unabridged, downloadable audiobook edition of Seven Brief Lessons on Physics written and read by Carlo Rovelli. These seven short lessons guide us, with admirable clarity, through the scientific revolution that shook physics in the 20th century and still continues to shake us today.

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.

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. 

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.

Claude Cohen-Tannoudji, prix Nobel de physique 1997, retrace son itinéraire personnel et scientifique et un demi-siècle d'évolution de la physique quantique. Sur ce sujet nul n'est mieux placé que lui, qui en a extrait les applications les plus caractéristiques et les plus étonnantes à la fois: la domestication –; et en particulier le refroidissement –; des atomes à l'aide de la lumière. La genèse de ces résultats révolutionnaires –; dont les applications commencent seulement à poindre aujourd'hui –; constitue un témoignage unique sur le développement de la physique et des techniques du XXè siècle.

Une histoire des notions d'espace et de temps. Des visions du cosmos dans la Grèce ancienne aux théories récentes sur la gravité quantique, Carlo Rovelli explore les métamorphoses de la notion d'espace et de temps. Une approche lumineuse de l'histoire des sciences par le biais de ces " coordonnées fondamentales de notre description du monde ". L'espace et le temps dans la physique contemporaine.

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.

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.

"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.

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".

One of our most beloved scientists, a fearless free spirit, Carlo Rovelli is also a masterful storyteller. In this collection of writings, the logbook of an intelligence always on the move, he follows his curiosity and invites us on a voyage through science, literature, philosophy and politics. Written with his usual clarity and wit, these pieces, most of which were first published in Italian newspapers, range widely across time and space.... 

Let us journey, with beloved physicist Carlo Rovelli, into the heart of a black hole. Let us slip beyond its boundary, the horizon, and tumble - on and on - down this crack in the universe. As we plunge, we'll see geometry fold, we'll feel the equations draw tight around us. Eventually, we'll pass it: the remains of a star, deep and dense and falling further far. And then - the bottom. Where time and space end, and the white hole is born.

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.

“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.”
