**"O'Shea tells the attention-grabbing tale of this mathematical secret and its resolution by means of the eccentric Mr. Perelman."― Wall highway magazine **

**In 1904, Henri Poincaré, a tremendous between mathematicians who reworked the fledging quarter of topology right into a strong box necessary to all arithmetic and physics, posed the Poincaré conjecture, a tantalizing puzzle that speaks to the prospective form of the universe. For greater than a century, the conjecture resisted makes an attempt to turn out or disprove it. As Donal O'Shea unearths in his stylish narrative, Poincaré's conjecture opens a door to the background of geometry, from the Pythagoreans of historical Greece to the prestigious geniuses of the nineteenth-century German academy and, eventually, to a desirable array of personalities―Poincaré and Bernhard Riemann, William Thurston and Richard Hamilton, and the eccentric genius who appears to be like to have solved it, Grigory Perelman. the answer turns out absolute to open up new corners of the mathematical universe.**
