HTML:One of TIME??s Ten Best Nonfiction Books of the Decade
"Meet the new Stephen Hawking . . . The Order of Time is a dazzling book." ??The Sunday Times
From the bestselling author of Seven Brief Lessons on Physics, Reality Is Not What It Seems, and Helgoland, comes a concise, elegant exploration of time. Why do we remember the past and not the future? What does it mean for time to "flow"? Do we exist in time or does time exist in us? 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 readers this is unfamiliar terrain. We all experience time, but the more scientists learn about it, the more mysterious it remains. 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. He explains how the theory of quantum gravity attempts to understand and give meaning to the resulting extreme landscape of this timeless world. Weaving together ideas from philosophy, science and literature, he suggests that our perception of the flow of time depends on our perspective, better understood starting from the structure of our brain and emotions than from the physical universe. Already a bestseller in Italy, and written with the poetic vitality that made Seven Brief Lessons on Physics so appealing, The Order of Time offers a profoundly intelligent, culturally rich, novel appreciation of the mysteries of… (més)
Amazing theories about something we really don't know much about. Rovelli first deconstructs our current suppositions about time, and there are so many. Then he explores a world without time as we know it. Then he reconstructs a concept of time that we can live with. Truly mind blowing, and there is only one formula in the whole shebang. I listened to it (read by Benedict Cumberbach) and then bought a hardback copy for further readings. ( )
Time is a human experience, it does not exist independently in the physical description of the world. This is a difficult but beautiful book, I read parts of it two or three times. Rovelli destroys the naive concept of time as a physical variable, by reference to the special and general theories of relativity, that show the duration of events vary depending on where the events occur in a gravitational field. His reconstruction of what time is for us starts with entropy, and he argues that the apparent flow of time is due to the low entropy of the primordial universe. He then locates time in our memory of our experiences, the story of our lives. The chapters open with verses from Horace's Odes, and Rovelli quotes from Hindu myths, discusses Husserl and Heidegger, recommends Proust as an expert in the science of memory. The penultimate chapter has a summary of the arguments of the rest of the book, and the last chapter is a reflection on the fear of death. p 142 "It is memory that solders together the processes, scattered across time, of which we are made. In this sense we exist in time. It is for this reason that I am the same person today that I was yesterday" ( )
Aja suhtelisuse osas informatiivne ja huvitav, aga kohati, eriti just lõpu poole, läheb teema raamidest välja ja liiga heietavaks. Ei tea millest tingitult, kas halvast tõlkest või keerulisest eneseväljendusest, nii mõnedki mõttekäigud raskesti mõistatavad. ( )

I stop and do nothing. Nothing happens. I am thinking about nothing. I listen to the passing of time.
This is time, familiar and intimate. We are taken by it. The rush of seconds, hours, years that hurls us toward life then drags us toward nothingness. . . . We inhabit time as fish live in water. Our being is being in time. Its solemn music nurtures us, opens the world to us, troubles us, frightens and lulls us. The universe unfolds into the future, dragged by time, and exists according to the order of time.

«Ogni giorno muoiono innumerevoli persone, eppure quelli che rimangono vivono come se fossero immortali» [Mahabharata III, 297]. Io non vorrei vivere come se fossi immortale. La morte non mi fa paura. Ho paura della sofferenza. Della vecchiaia, anche se ora meno, vedendo la vecchiaia serena e bella di mio padre. Ho paura della debolezza, della mancanza di amore. Ma la morte non mi fa paura. Non mi faceva paura da ragazzo, ma allora pensavo fosse solo perché mi sembrava lontana. Ma ora, a sessant'anni, la paura non è arrivata. Amo la vita, ma la vita è anche fatica, sofferenza, dolore. Penso alla morte come a un meritato riposo. Sorella del sonno, la chiama Bach nella meravigliosa cantata BWV 56. Una sorella gentile che verrà presto a chiudere i miei occhi e accarezzarmi la testa.
E il canto, come aveva osservato Agostino, è la consapevolezza del tempo. È il tempo. È l'inno dei Veda che è esso stesso lo sbocciare del tempo. Nel Benedictus della “Missa Solemnis” di Beethoven il canto del violino è pura bellezza, pura disperazione, pura felicità. Vi restiamo sospesi trattenendo il fiato, sentendo misteriosamente che è questa la sorgente del senso. È questa la sorgente del tempo.

In the Benedictus of Beethoven’s Missa Solemnis, the song of the violin is pure beauty, pure desperation, pure joy. We are suspended, holding our breath, feeling mysteriously that this must be the source of meaning. That this is the source of time.
Then the song fades and ceases. "The silver thread is broken, the golden bowl is shattered, the amphora at the fountain breaks, the bucket falls into the well, the earth returns to dust." And it is fine like this. We can close our eyes, rest. This all seems fair and beautiful to me. This is time.
