Che cos'è il tempo? Questa domanda solo apparentemente semplice è il problema di per sé più importante che la scienza fronteggia nella sua esplorazione dei fondamenti dell'universo. Tutti i misteri affrontati dai fisici e dai cosmologi - dal Big Bang al futuro dell'universo, dagli enigmi della fisica quantistica all'unificazione delle forze e delle particelle - si riducono essenzialmente al problema della natura del tempo. La realtà del tempo ...

One of our foremost thinkers and public intellectuals offers a radical new view of the nature of time, and explores its implications for everything from physics and cosmology to economics and climate change.What is time? It's the sort of question we rarely ask because it seems so obvious. And yet, to a physicist, time is simply a human construct and an illusion: if you could somehow get outside the universe and observe it from there, you would...

With clarity, passion, and authority, renowned theoretical physicist Smolin charts the rise and fall of string theory and takes a fascinating look at what will replace it.

Presents an account of the state of modern physics: of how we got from Einstein and Relativity through quantum mechanics to the strange and bizarre predictions of string theory, full of unseen dimensions and multiple universes.
