 The town of Cheltenham—famous for its jazz, music, and literature festivals— added science to its portfolio with the creation of the Cheltenham Science Festival in 2002.As science organizations and funding bodies put ever more emphasis on outreach to foster public understanding both of the results and the wider relevance of science, recent years have seen the creation of a number of new science festivals.An umbrella organization for European science festivals and other science communication events, the European Science Events Association (EUSEA), was formed in 2001 and now has approximately 100 member organizations from 36 different countries.
