Autobiography by this child prodigy and "mental calculator" who for a brief period was a sensation on two continents. "Colburn's abilities developed rapidly and he was soon able to solve such problems as the number of seconds in 2,000 years, the product of 12,225 and 1,223, or the square root of 1,449. When he was seven years old he took six seconds to give the numbers of hours in thirty-eight years, two months, and seven days. Zerah is reported to have been able to solve fairly complex problems. For example, the sixth Fermat number...The question is whether this number, 4,294,967,297, is prime or not. Zerah calculated in his head that it was not and has a divisor of 641. The other divisor is 6,700,417 and can easily be found using a calculator." -Wikipedia. He lost his powers with the onset of adulthood.
