"A captivating journey to the outer frontiers of human knowledge by the popular presenter of Netflix's The Story of Math. Ever since the dawn of civilization we have been driven by a desire to know--to understand the physical world and the laws of nature. But are there limits to human knowledge? This tantalizing question has inspired scientists and functioned as a spur to innovation. Now, Marcus du Sautoy invites us to join him on a journey to the outer reaches of human understanding as there are still lots of deep mysteries waiting to be solved. Are some things beyond the predictive powers of science? Or are those challenges simply the next big discovery waiting to happen? Du Sautoy takes us into the minds of science's greatest innovators and reveals the fraught circumstances of their discoveries. He reminds us that major breakthroughs were often ridiculed at the time of their discovery. And he carries us on a whirlwind tour of seven Edges of knowledge--chaos theory, matter, quantum physics, the universe, time, consciousness and infinity--grounding a deeply personal exploration in simple concepts like the roll of dice, the notes of a cello, or how a clock measures time"-- Provided by publisher.
