The budding geniuses, ages 15 and 12 respectively, earned official IQ scores of 162, putting them in the top 1 percent of the population. (The average IQ is 100.)

But they're hardly the first youngsters to beat Einstein in the smarts department — at least on paper.

Here, a few notable kids who recently scored higher than Mr. Relativity:

1. Fabiola Mann
Age tested: 15
IQ score: 162
Fabiola, who was born in Goa, India, but currently lives in the U.K., recently begged her parents to pay the fee and let her take Mensa's IQ test. The 15-year-old "has a purple belt in karate and is now taking tae kwon do in school," says Forbes. She enjoys the classic genius hobby of chess, plays the piano and guitar, and can sing as well. "Yes, she is a human being and not an Indian cyborg."
