The Man Who Knew Infinity

Arithmetic equations in an audiobook? In Humphrey Bower's eloquent reading of this lauded 1991 biography of one of the world's most brilliant and mystifying mathematicians, spoken numbers manage not to confuse. Admittedly, being able to see them would be nice, but mathematically inclined listeners can write down the equations as Bower reads, and non-math listeners wouldn't really learn much from seeing the numbers anyway. They can join everyone else in appreciating the story of Indian genius Srinivasa Ramanujan. Bower reads with interest and command. He paces the math discussions to interest all listeners, and his command of British and Indian intonations adds color to the dialogue and quotations. Introduced with atmospheric music, this is a classy production. A.C.S. Winner of AudioFile Earphones Award (c) AudioFile 2008, Portland, Maine

This moving and astonishing biography tells the improbable story of India-born Srinavasa Ramanujan Iyengar, self-taught mathematical prodigy. In 1913 Ramanujan, a 25-year-old clerk who had flunked out of two colleges, wrote a letter filled with startlingly original theorems to eminent English mathematician G. H. Hardy. Struck by the Indian's genius, Hardy, member of the Cambridge Apostles and an obsessive cricket aficionado, brought Ramanujan to England. Over the next five years, the vegetarian Brahmin who claimed his discoveries were revealed to him by a Hindu goddess turned out influential mathematical propositions. Cut off from his young Indian wife left at home and emotionally neglected by fatherly yet aloof Hardy, Ramanujan returned to India in 1919, depressed, sullen and quarrelsome; he died one year later of tuberculosis. Kanigel ( Apprentice to Genius ) gives nontechnical readers the flavor of how Ramanujan arrived at his mathematical ideas, which are used today in cosmology and computer science.
