Fermat’s Last Theorem

Simon Singh

In 1963 a schoolboy called Andrew Wiles reading in his school library came across the world’s greatest mathematical problem; Fermat’s Theorem(定理). First put forward by the French mathematician Pierre de Fermat in the seventeenth century, the theorem had baffledand beaten the finest mathematical minds, including a French woman scientist who made a major advance in working out the problem, and who had to dress like a man in order to be able to study at the Ecole Polytechnique. Through unbelievable determination Andrew Wiles finally worked out the problem in 1995. An unusual story of human effort over three centuries, Fermat’s Last Theorem will delight specialists and general readers alike.
