Known as the Manhattan Project, this super-secretive wartime project had the stoic visage of Oppenheimer overseeing the greatest experiment ever conducted by humankind.

Fighting - including miserable trench warfare - broke out in practically every corner of Europe and spread around the world to Africa, Asia, and the Middle East.

Jane Austen wrote that in her novels she painted the world on a “little bit (two inches wide) of ivory,� working “with so fine a brush.� Her well-known books, such as Pride and Prejudice and Emma, display the power of this approach; her observations about human nature have proven so accurate and entertaining that her books continue to be beloved 200 years after they were written.

Alan Turing had a radical and ingenious mind. He is considered one of the fathers of artificial intelligence, and his theories on this matter range from purely mechanical to almost spiritual. During World War II, his decryption of the Nazis’ Enigma codes proved vital for the Allied victory over the Axis powers.

It was Tesla's theories, patents, and experiments that would pave the way for the digital, wireless world we are so familiar with today. Tesla didn't enjoy the high honors bestowed on so many of his contemporaries, yet he enjoyed the power of knowing that it was his inventions that were powering the world, literally.

He established that all species of life have descended over time from common ancestors and, in a joint publication with Alfred Russel Wallace, introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding.

Eminent scholar Guy de la Bedoyere, author of Praetorian, asserts that the women behind the scenes - including Livia, Octavia, and the elder and younger Agrippina - were the true backbone of the dynasty.
