Carlo Rovelli

Non lo so se l’idea che i buchi neri finiscano la loro lunga vita trasformandosi in buchi bianchi sia giusta. È il fenomeno che ho studiato in questi ultimi anni. Coinvolge la natura quantistica del tempo e dello spazio, la coesistenza di prospettive diverse, e la ragione della differenza fra passato e futuro. Esplorare questa idea è un’avventura ancora in corso. Ve la racconto come in un bollettino dal fronte. Cosa sono esattamente i buchi neri, che pullulano nell’universo. Cosa sono i buchi bianchi, i loro elusivi fratelli minori. E le domande che mi inseguono da sempre: come facciamo a capire quello che non abbiamo mai visto? Perché vogliamo sempre andare a vedere un po’ più in là...? —Carlo Rovelli

Dans ce court essai, Carlo Rovelli s'interroge sur la notion d'espace et de temps et discute des tentatives de réponses apportées par les théories anciennes et actuelles : relativité générale, mécanique quantique, gravité quantique, cordes et autres boucles...En livrant ses réflexions de physicien qu'il lie intimement à son parcours personnel, ses déboires et ses succès, Carlo Rovelli témoigne de ce que sont la science et la mission du chercheur.

The Number One bestselling author of The Order of Time is back with a stunning book about the enigma of quantum physics In June 1925, twenty-three-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. Countless experiments have led to practical applications that shape our daily lives. Today our understanding of the world around us is based on this theory. And yet it is still profoundly mysterious. In this enchanting book, Carlo Rovelli, one of our most celebrated scientists, tells the extraordinary story of quantum physics and reveals its deep meaning: a world made of substances is replaced by a world made of relations, each particle responding to another in a never ending game of mirrors. Shifting our perspective once again, Rovelli takes us on a riveting journey through the universe so we can better understand our place in it.

A startling new look at quantum theory, from the bestselling author of Seven Brief Lessons on Physics and The Order of Time. 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 twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.

Este libro aborda uno de los mayores misterios de la física cuántica: ¿de qué está compuesta, en definitiva, la realidad?, ¿cuál es la estructura profunda de las cosas?, ¿cómo se conjuga la gramática de la naturaleza? A medida que nuestros instrumentos de observación se perfeccionan, surgen nuevas estructuras cuyo comportamiento desafía las leyes de la lógica. Rovelli logra aclarar los entresijos de la teoría de la relatividad general y los últimos descubrimientos en torno a los agujeros negros, mientras nos contagia su entusiasmo por la belleza del cosmos y por las sorpresas que puede depararnos nuestro viaje a la última frontera del conocimiento físico.

Carlo Rovelli, uzmanlığı kuantum çekimi olan bir fizikçi ve öğretim üyesidir. Bir yandan da bilim tarihi ve felsefesi alanında çalışmakta ve dersler vermektedir. Rovelli'nin geliştirdiği "termik zaman" hipotezine göre zaman, temel teori düzeyinde var olan bir şey değildir; zaman yalnızca termodinamik bir bağlamda ortaya çıkar ve akış hâlinde olduğu da bir yanılsamadır. Rovelli bu kitabında, ülkemiz toprakları üstündeki Milet'te 2.600 yıl önce yaşayan Anaksimandros'un düşüncelerini inceliyor. Bunu yaparken kadim bilgenin yaşadığı dönemi tasvir etmekle yetinmiyor, Anaksimandros'u düşünce tarihinin önceki ve sonraki dönemleriyle de ilişkilendiriyor. Böylece okuru, Bâbil, İskenderiye, Çin gibi uygarlıkların kültürleri ve düşünce geleneklerinden Batlamyus'a, Galilei'ye, Newton'a, Heisenberg'e ve Einstein'a uzanan tadına doyulmaz bir bilim tarihi gezintisine çıkarıyor. Açık ve anlaşılır üslubuyla, sadece bilim tarihi ile felsefesini değil, astronomiyi, kozmolojiyi, antropolojiyi, arkeolojiyi, dilbilimi, din felsefesini, kısacası doğa ve kültür üzerine sistematik ve eleştirel düşünmeyi çok sevdiren bir kitap... "Bilimin gücü, içerdiği kesinliklerden kaynaklanmaz; aksine, cehaletimizin büyüklüğü hususunda giderek artan bir şuurdan kaynaklanır. Bizi, bildiğimizi sandığımız şeylerden hiç durmadan şüphelenmeye ve böylece devamlı öğrenmeye iten de bu şuurdur. Bilgisel araştırma, kesinliklerden beslenmez: Kesinliklerin radikal biçimde mevcut olmamasından beslenir. Akıcı ve de sürekli gelişim hâlindeki bilimsel düşünce, büyük bir güce ve mahirane bir sihre sahiptir: Dünyanın düzenini altüst etmeye ve dünyayı yeniden düşünmeye muktedirdir.

https://goodbooksummary.com/reality-is-not-what-it-seems-by-carlo-rovelli-book-summary/ ************* Physics has been around for a long time. The scholars of Greece were the first people to utilize reason. Scientific methods using accurate and repeatable experimentation were formulated during the Middle Ages. This made Newton develop a theory about the world in which both time and space were absolute.

From the best-selling author of Seven Brief Lessons on Physics comes a new book about the mind-bending nature of the universe What are time and space made of? Where does matter come from? And what exactly is reality? Scientist Carlo Rovelli has spent his whole life exploring these questions and pushing the boundaries of what we know. Here he explains how our image of the world has changed throughout centuries. Fom Aristotle to Albert Einstein, Michael Faraday to the Higgs boson, he takes us on a wondrous journey to show us that beyond our ever-changing idea of reality is a whole new world that has yet to be discovered.

«Ci sono frontiere, dove stiamo imparando, e brucia il nostro desiderio di sapere. Sono nelle profondità più minute del tessuto dello spazio, nelle origini del cosmo, nella natura del tempo, nel fato dei buchi neri, e nel funzionamento del nostro stesso pensiero. Qui, sul bordo di quello che sappiamo, a contatto con l'oceano di quanto non sappiamo, brillano il mistero del mondo, la bellezza del mondo, e ci lasciano senza fiato». Tale è il presupposto di queste «brevi lezioni», che ci guidano, con ammirevole trasparenza, attraverso alcune tappe inevitabili della rivoluzione che ha scosso la fisica nel secolo XX e la scuote tuttora: a partire dalla teoria della relatività generale di Einstein e della meccanica quantistica fino alle questioni aperte sulla architettura del cosmo, sulle particelle elementari, sulla gravità quantistica, sulla natura del tempo e della mente.

All the beauty of modern physics in fewer than a hundred pages. This is a book about the joy of discovery. A playful, entertaining, and mind-bending introduction to modern physics, it's already a major bestseller in Italy and the United Kingdom. Carlo Rovelli offers surprising—and surprisingly easy to grasp—explanations of 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. 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. “Here, on the edge of what we know, in contact with the ocean of the unknown, shines the mystery and the beauty of the world,” Rovelli writes. “And it’s breathtaking.”

Czas jest naprawdę zagadkowy. A Carlo Rovelli jak nikt inny potrafi rozświetlać naukowe zagadki w sposób, który nam wszystkim otwiera oczy na zupełnie nowe światy – światy skryte w gąszczu tajemnych wzorów fizyki teoretycznej. Obraz czasu przed Newtonem. Obraz czasu po Einsteinie. Czas cieplny. Gdzie się podziała teraźniejszość? Czy czas rzeczywiście spowalnia się i przyspiesza? Dlaczego wszechświat miał dawniej mniejszą entropię? Czy istnieją kwanty czasu? Z czasem jest jak z płatkiem śniegu na dłoni – stopniowo, gdy mu się przyglądasz, roztapia się pomiędzy palcami i znika. Tradycyjnie myślimy o czasie jako o czymś podstawowym, linearnym, co płynie jednostajnie i niezależnie od wszystkiego innego. Przeszłość jest ustalona, przyszłość pełna możliwości… Wszystko to okazało się nieprawdziwe. To, co nazywamy „czasem”, jest złożonym zbiorem struktur. Poddając czas coraz dokładniejszej i głębszej analizie, kawałek po kawałku, odarliśmy go z kolejnych warstw. Właśnie o tym jest ta książka. Ale nie tylko. W bezczasowym świecie musi przecież istnieć coś, co prowadzi do wykształcenia się takiego czasu, do jakiego przywykliśmy – z jego porządkiem, przeszłością różną od przyszłości i gładkim płynięciem. Nasz czas musi się jakoś wokół nas wyłaniać, przynajmniej dla nas i w naszej skali.

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 different speeds 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. With his extraordinary charm and sense of wonder, bringing together science, philosophy and art, Carlo Rovelli unravels this mystery, inviting us to imagine a world where time is in us and we are not in time.

In this collection of writings, the logbook of an intelligence always on the move, Carlo Rovelli follows his curiosity and invites us on a voyage through science, history, philosophy and politics. Written with his usual clarity and wit, these pieces range widely across time and space: from Newton's alchemy to Einstein's mistakes, from Nabokov's butterflies to Dante's cosmology, from travels in Africa to the consciousness of an octopus, from mind-altering psychedelic substances to the meaning of atheism. Charming, pithy and elegant, this book is the perfect gateway to the universe of one of the most influential scientists of our age.

A delightful intellectual feast from the bestselling author of Seven Brief Lessons on Physics and The Order of Time 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 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. Written with his usual clarity and wit, this journey ranges widely across time and space: from Newton's alchemy to Einstein's mistakes, from Nabokov's epidopterology to Dante's cosmology, from mind-altering psychedelic substances to the meaning of atheism, from the future of physics to the power of uncertainty. Charming, pithy and elegant, this book is the perfect gateway to the universe of one of the most influential minds of our age.

Was ist Zeit? Wir messen sie immer nur im Vergleich mit etwas anderem, einem Stern oder einem Pendel, und selbst dann gehen die Uhren nicht immer gleich, wie Einstein zeigte. Brauchen wir sie also, um die Grundlagen unseres Universums zu erklären? Nein, sagt Carlo Rovelli und skizziert ein neues Modell davon, was die Welt im Innersten zusammenhält. Zugleich ist dies das bislang persönlichste Buch des weltbekannten Physikers, der uns erzählt, wie ein Grundlagenforscher zu seinen Ideen kommt und warum revolutionäres Denken immer ein Abenteuer mit ungewissem Ausgang ist.

A mesmerizing trip to the strange world of white holes from the bestselling author of Seven Brief Lessons on Physics and The Order of Time 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. He traces the ongoing adventure of his own cutting-edge research, investigating whether all black holes could eventually turn into white holes, equally compact objects in which the arrow of time is reversed. Rovelli writes just as compellingly about the work of a scientist as he does the marvels of the universe. He shares the fear, uncertainty, and frequent disappointment of exploring hypotheses and unknown worlds, and the delight of chasing new ideas to unexpected conclusions. Guiding us beyond the horizon, he invites us to experience the fever and the disquiet of science—and the strange and startling life of a white hole.
