The mission of Science Hack Day is to get excited and make things with science! A Hack Day is an event that brings together designers, developers, scientists, citizen scientists, web geeks, young people, the public, basically anyone with good ideas in the same physical space for a brief but intense period of collaboration, hacking, and building ‘cool stuff’. Hack Days were originally created by Yahoo! in 2005 and soon after became a worldwide trend. By collaborating on focused tasks during this short period, small groups of hackers are capable of producing remarkable results. Some Hack Days have a specific focus. There have already been very successful Music Hack Days and Government Hack Days. It’s time for a Hack Day focused on science!
