Our April meeting was a Members Evening, with two members giving us talks about things that interested them. Hugh Alford gave us a talk about the Renaissance philosopher Giordano Bruno, who was convicted by the Roman Inquisition of heresy and burned at the stake in February 1600, at least partly because of his beliefs about the infinite nature of the universe. Mike McRoberts gave us a talk about his Earthshine 1 high-altitude balloon project, which included video of the Orion 1 balloon launched last month.
