From one of our foremost thinkers and public intellectuals, a radical new view of the nature of time and the cosmos.
What is time?
This deceptively simple question is the single most important problem facing science as we probe more deeply into the fundamentals of the universe. All of the mysteries physicists and cosmologists face—from the Big Bang to the future of the universe, from the puzzles of quantum physics to the unification of forces and particles—come down to the nature of time.
The fact that time is real may seem obvious. You experience it passing every day when you watch clocks tick, bread toast, and children grow. But most physicists, from Newton to Einstein to today’s quantum theorists, have seen things differently. The scientific case for time being an illusion is formidable. That is why the consequences of adopting the view that time is real are revolutionary.
Lee Smolin, author of the controversial bestseller The Trouble with Physics, argues that a limited notion of time is holding physics back. It’s time for a major revolution in scientific thought. The reality of time could be the key to the next big breakthrough in theoretical physics.
What if the laws of physics themselves were not timeless? What if they could evolve? Time Reborn offers a radical new approach to cosmology that embraces the reality of time and opens up a whole new universe of possibilities. There are few ideas that, like our notion of time, shape our thinking about literally everything, with huge implications for physics and beyond—from climate change to the economic crisis. Smolin explains in lively and lucid prose how the true nature of time impacts our world.
The Age of Wonder

A riveting history of the men and women whose discoveries and inventions at the end of the eighteenth century gave birth to the Romantic Age of Science.
When young Joseph Banks stepped onto a Tahitian beach in 1769, he hoped to discover Paradise. Inspired by the scientific ferment sweeping through Britain, the botanist had sailed with Captain Cook on his first "Endeavour "voyage in search of new worlds. Other voyages of discovery--astronomical, chemical, poetical, philosophical--swiftly follow in Richard Holmes's original evocation of what truly emerges as an Age of Wonder.
Brilliantly conceived as a relay of scientific stories, "The Age of Wonder" investigates the earliest ideas of deep time and space, and the explorers of "dynamic science," of an infinite, mysterious Nature waiting to be discovered. Three lives dominate the book: William Herschel and his sister Caroline, whose dedication to the study of the stars forever changed the public conception of the solar system, the Milky Way, and the meaning of the universe; and Humphry Davy, who, with only a grammar school education stunned the scientific community with his near-suicidal gas experiments that led to the invention of the miners' lamp and established British chemistry as the leading professional science in Europe. This age of exploration extended to great writers and poets as well as scientists, all creators relishing in moments of high exhilaration, boundary-pushing and discovery.
Holmes's extraordinary evocation of this age of wonder shows how great ideas and experiments--both successes and failures--were born of singular and often lonely dedication, and how religious faith and scientific truth collide. He has written a book breathtaking in its originality, its storytelling energy, and its intellectual significance.

In 1931 the mathematical logician Kurt Godel published a revolutionary paper that challenged certain basic assumptions underpinning mathematics and logic. A colleague of physicist Albert Einstein, his theorem proved that mathematics was partly based on propositions not provable within the mathematical system. The importance of Godel's Proof rests upon its radical implications and has echoed throughout many fields, from maths to science to philosophy, computer design, artificial intelligence, even religion and psychology. While others such as Douglas Hofstadter and Roger Penrose have published bestsellers based on Godel’s theorem, this is the first book to present a readable explanation to both scholars and non-specialists alike. A gripping combination of science and accessibility, Godel’s Proof by Nagel and Newman is for both mathematicians and the idly curious, offering those with a taste for logic and philosophy the chance to satisfy their intellectual curiosity.
