As freelance journalist (and brother of novelist Jonathan Safran Foer) Joshua Foer proves in "Moonwalking with Einstein," memorization can be anything but boring. Foer examines ancient memory techniques and consults experts across the country in an attempt to explore the human capacity for memory. "Moonwalking with Einstein" is full of vibrant characters, like a savant who claims to have memorized over 9,000 books. Foer's research even earns him a spot in the US Memory Championships.
