Michael Kearney won $1 million on AOL's scavenger hunt game "Gold Rush". Now besides winning the bounty, Michael is quite an interesting guy:
"Gold Rush" wasn't an academic competition, but intelligence certainly didn't hurt Kearney. The child prodigy graduated from high school at the age of 6, college at age 10, earned a Masters degree in chemistry at age 14, and a Masters in computer science at 18. He's currently working on his doctorate in chemistry.
