child genius

http://en.wikipedia.org/wiki/Child_prodigy

A prodigy is someone who, at an early age, masters one or more skills far beyond his or her level of maturity.^[1] One criterion for classifying prodigies is: a prodigy is a child, typically younger than 18 years old, who is performing at the level of a highly trained adult in a very demanding field of endeavour.^[1][2]
The giftedness of prodigies is determined by the degree of their talent relative to their ages. Examples of particularly extreme prodigies could include Mozart and Jackie Evancho in music,^[3][4] Magnus Carlsen, Sergey Karjakin, and Judit Polgar in chess, Carl Friedrich Gauss, Srinivasa Ramanujan, William James Sidis, Michael Kearney, Gregory R. Smith, and John von Neumann in mathematics, Pablo Picasso in art, and Saul Kripke in philosophy.^[5] There is controversy as to at what age and standard to use in the definition of a prodigy.

I wrote Eye of the Pharaoh at age 15-16 years of age.
It took "10 PhD candidates" to decipher what I wrote (not the story part that ties together my science).
