The Art of the Infinite takes infinity, in its countless guises, as a touchstone for understanding mathematical thinking. Robert and Ellen Kaplan guide us through the “Republic of Numbers,” where we meet both its upstanding citizens and its more shadowy dwellers; and transport us across the plane of geometry into the unlikely realm where parallel lines meet.

Our species, it appears, is hardwired to get things wrong in myriad different ways. Why did recipients of a loan offer accept a higher rate of interest when a pretty woman's face was printed on the flyer? Why did one poll on immigration find the most despised aliens were ones from a group that did not exist? What made four of the Air Force's best pilots fly their planes, in formation, straight into the ground?

Who hasn't feared the math Minotaur in its labyrinth of abstractions? Now, in Out of the Labyrinth, Robert and Ellen Kaplan - the founders of The Math Circle, the popular learning program begun at Harvard in 1994 - reveal the secrets behind their highly successful approach, leading listeners out of the labyrinth and into the joyous embrace of mathematics.

A squared plus b squared equals c squared. It sounds simple, doesn’t it? Yet this familiar expression opens a gateway into the riotous garden of mathematics, and sends us on a journey of exploration in the company of two inspired guides, Robert and Ellen Kaplan. With wit, verve, and clarity, they trace the life of the Pythagorean theorem, from ancient Babylon to the present, visiting along the way Leonardo da Vinci, Albert Einstein, President James Garfield, and the Freemasons - not to mention the elusive Pythagoras himself.
