"SUMMER CAMP FOR SCIENTISTS John Coates, a former Wall Street trader who is investigating the role that testosterone and other hormones play in financial risk-taking, is going to Science Foo Camp in July. It is an invitation-only, three-day event organized by Google, Nature Publishing Group and O'Reilly Media that is gaining a reputation as the Davos of the scientific research world. Dr. Coates, a Canadian who is a senior research fellow at the University of Cambridge, started wondering if hormones were related to trading decisions during the dot.com bubble in the late 1990s. His friend John Mighton, an award-winning Toronto playwright and mathematician who started charity JUMP Math to help children learn math, is also going. Foo camp brings together 200 guests, including Nobel laureates and original thinkers from a wide variety of fields, for an unorthodox conference at the Googleplex in Mountain View, Calif. Dr. Mighton says he is looking forward to meeting big names in artificial intelligence and quantum information, and is thinking about how to describe himself to his fellow campers. In past years, there have been reports that guests can use only three words when they introduce themselves to the group. The rule is enforced with a gong."
