A man with no home and no job, Paul Erdos was the most prolific mathematician who ever lived. Born in Hungary in 1913, Erdos wrote and co-authored over 1,500 papers and pioneered several fields in theoretical mathematics. At the age of 83 he still spent most of his time on the road, going from math meeting to math meeting, continually working on problems. He died on September 20, 1996 while attending such a meeting in Warsaw, Poland. N is a number:...

Turing can be regarded as one of the greatest scientists of the 20th century. But who was Turing, and what did he achieve during his tragically short life of 41 years? Best known as the genius who broke Germany's most secret codes during the war of 1939-45, Turing was also the father of the modern computer. Today, all who 'click-to-open' are familiar with the impact of Turing's ideas. Here, B. Jack Copeland provides an account of Turing's life and...

From a riveting new voice in suspense fiction, THE ASCENDANT is an action-packed thrillers following a unlikely hero--a number savant named Garrett Reilly--as he races around the globe to avert total war--

The world's first computer programmer and daughter of Lord Byron finally gets credit for her research in this gossipy short biography Over 150 years after her death, a widely-used scientific computer program was named Ada, after Ada Lovelace, the only legitimate daughter of the eighteenth century's version of a rock star, Lord Byron. Why? Because, after computer pioneers such as Alan Turing began to rediscover her, it slowly became apparent that...

Julia Robinson, a pioneer among American women in mathematics, rose to prominence in a field where often she was the only woman. Julia Robinson was the first woman elected to the mathematical section of the National Academy of Sciences, and the first woman to become president of the American Mathematical Society. Her work, and the exciting story of the path that led to the solution of Hilbert's tenth problem in 1970, produced an unusual friendship...

In 1942 a secret U.S. military program was launched to recruit women to the war effort. But unlike the efforts to recruit Rosie the Riveter to the factory, this clandestine search targeted female mathematicians who would become human 'computers' for the U.S. Army. From the bombing of Axis Europe to the assaults on Japanese strongholds, women worked around-the-clock six days a week, creating ballistics tables that proved crucial to Allied success....

Drawing on the manuscript of Mehlberg's own unpublished memoir, supplemented with meticulous research, two historians and Holocaust experts tell the astonishing true story of Dr. Josephine Janina Mehlberg who saved thousands of lives in Nazi-occupied Poland by masquerading as a Polish aristocrat.
