Growing up poor in Madras, India, Srinivasa Ramanujan Iyengar earns admittance to Cambridge University during WWI, where he becomes a pioneer in mathematical theories with the guidance of his professor, G.H. Hardy.

A gripping story of mathematics, computers, cryptography, and homosexual persecution. Hodges tells how Turing's revolutionary idea of 1936-- the concept of a universal machine-- laid the foundation for the modern computer. Turing brought the idea to practical realization in 1945 with his electronic design. This work was directly related to Turing's leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was...

"Ada Lovelace turned her powerful imagination into a vision of the future, predicting the impact of computers on human life. Lovelace had a unique education and embraced mathematics. She became one of the biggest believers in engineer Charles Babbage's ideas for calculation machines. This graphic biography shows how Lovelace helped spread awareness of what an early computer could do and how she became one of the first computer programmers. It also...

"Regarded as the most influential scientist of all time, Isaac Newton made amazing strides in both physics and mathematics. From formulating the laws of motion and universal gravitation to building the first reflecting telescope, Newton was the scientific revolutionist of his time. This title includes primary sources, sidebars, prompts and activities, charts and graphs, and much more." -- From publisher's website.

One of the greatest thinkers of all time, Isaac Newton gave the world an accurate understanding of forces and motion throughout the universe. He went to college but learned much about science on his own, by observing, experimenting, and thinking carefully. Newton's laws of motion explain, in a few sentences, how and why things move, or don't move, when forces act on them. He also studied and described gravity and the makeup of light, and he created...

"Even by 1800s standards, Ada Byron Lovelace had an unusual upbringing. Her narcissistic mother worked hard at cultivating her own role as martyred ex-wife of bad-boy poet Lord Byron and had Ada tutored at home by some of the brightest minds. Ada developed a hunger for mental puzzles, mathematical conundrums, and scientific discovery that kept pace with the breathtaking advances of the industrial and social revolutions taking place in Europe. At seventeen,...

In this book discover the life of Alan Turing, the genius code cracker and father of theoretical computer science and artificial intelligence. Alan grew up in England, where his best friends were numbers and a little boy called Christopher. When his young friend died, Alan retreated to the world of numbers and codes, where he discovered how to crack the code of the Nazi Enigma machine.

Alan Turing is 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.
