Chronicle of Higher Education: This year’s TED conference winds down today in Long Beach, California. Short for Technology, Entertainment, Design, TED features short talks by eloquent, engaging experts from diverse fields, including the physical sciences. As the Chronicle‘s Jeffrey Young explains, TED is unlike the kind of conferences that academics usually attend. Talks are just 18 minutes long, lack question-and-answer sessions at the end, and are professionally videoed and posted on the Web. Among the speakers at this year’s event is Aaron O’Connell, who is part of the team that succeeded in nudging a tiny cantilever in and out of its quantum ground state.
