Will future brain imaging allow scientists to read your mind? What does "nothing" really mean, and what is time? Does free will exist? Has intelligence evolved in parallel amongst many species, or is it unique to humans? These are just a few of the topics that will be tackled over the next four days at the second annual World Science Festival. The festival brings together an impressive list of participants: E.O. Wilson, Oliver Sacks, Alan Alda, Glenn Close, Yo-Yo Ma, and Dean Kamen, to name a few. The crème de la crème of the scientific community (including a number of Nobel Laureates), performing and visual artists, innovators in business, and policy-makers will engage in a public discussion about science and encourage scientific discovery and education.
