One hundred years ago, Albert Einstein changed the world with four papers that led directly to the development of atomic weapons, space travel, satellite technology and a profound understanding of the universe.

But, wracked with guilt over the real - world applications of his science – specifically, how the use of atomic weapons clashed with his religious beliefs – Einstein spent the last half of his life desperately trying to disprove the implications of so much of his work.

Learn how the greatest scientist of the 20th century would spend his final years enduring appalling professional humiliation. While most of the world hailed him as a genius, he slowly became a marginal figure within the scientific community – revered, but ignored. And it was all because he could not accept the fact that his life's work stood at odds with his personal beliefs.
