NOVA explorers whether it's possible for anyone to become a genius or if such smarts are purely a result of one's DNA. Also: a man who became an extraordinary musician following a head injury; a man who can match any past or future date to its day of the week; a "memory athlete" who remembers strings of hundreds of random numbers. Also: Host David Pogue undergoes a high-resolution brain scan to see how his brain compares to Albert Einstein's.
