they say he drowned because he couldn't swim, I thought people that smart usually are pretty co-ordinated.

Rajeev Motwani, a Stanford computer scientist, close advisor to Google (GOOG) founders Sergey Brin and Larry Page, and one of Silicon Valley's most important tech investors and thinkers, was found dead in his swimming pool on Friday. According to the San Jose Mercury News, Motwani threw a party to celebrate the end of the school year on Thursday night; afterwards, he wandered out to his backyard to relax with a cigar. Apparently, Motwani did not know how to swim, and the family's nanny discovered his body the following morning.

While at Stanford, Motwani advised Brin and Page when they began to conduct data-mining research that would eventually create Google. He was the founder of the Mining Data at Stanford Project and a member of the Indus Engineers, an informal collection of South Asian high-tech workers in the Valley. According to Bloggingstocks.com, he was an early investor in PayPal and Google, the author of the book Randomized Algorithms, and a recipient of the Godel Prize for excellence in computer science.
