Top 10 Best Science Festivals in the World — From Edinburgh to Tokyo

Edinburgh's International Science Festival opened in 1989 as the world's first of its kind and still anchors this list, alongside Brian Greene's World Science Festival in New York and Starmus, the astronomy-focused gathering where Stephen Hawking once shared a stage with Queen guitarist Brian May. The mix ranges from Pint of Science, which puts researchers in pubs across more than 25 countries, to Trinity College Dublin's Science Gallery, whose art-meets-science exhibitions have spread to satellite spaces in London, Melbourne, Bengaluru and Detroit. Together these events turn laboratories and lecture halls into public spectacle, from outback stargazing in Australia to robotics showcases in Tokyo.
