The Invisible Century

"Though they met just once, and even then didn't know what to make of each other's work, Albert Einstein and Sigmund Freud had more in common than they might have imagined. Each had explored the foremost problem in his field, and each had found himself confronting the same obstacle: a lack of evidence - or at least evidence as science then knew it. In this narrative, Richard Panek joins them on the parallel journeys of discovery that altered forever not only what or how much we see, but the very nature of seeing itself."--Jacket.
