Combining a wealthy historic narrative along with his personal own trip as a mathematician, Marcus du Sautoy takes a different look at the mathematical brain as he explores deep conjectures approximately symmetry and brings us face-to-face with the oddball mathematicians, either previous and current, who've battled to appreciate symmetry's elusive traits. He explores what's maybe the main intriguing discovery to date—the summit of mathematicians' mastery within the field—the Monster, an immense snowflake that exists in 196,883-dimensional house with extra symmetries than there are atoms within the sunlight.

what's it prefer to clear up an historic mathematical challenge in a flash of concept? what's it prefer to be proven, ten mins later, that you've made a mistake? what's it prefer to see the realm in mathematical phrases, and what can that let us know approximately lifestyles itself? In Symmetry, Marcus du Sautoy investigates those questions and exhibits mathematical beginners what it seems like to grapple with essentially the most complicated principles the human brain can understand.
