Known as much for hosting lectures and talks as being a first-class music bar and hipster hangout, the original westside Happy Dog has become a place where you can find out about both local and national issues. Now that the Happy Dog at Euclid Tavern has open, eastsiders can expect the same kind of programming. Tonight, for instance, NASA’s Calvin Robinson will give a lecture dubbed Rapid Scientific Analysis through Visualization. We don’t know exactly what that means but it sure sounds intriguing. The talk begins at 7:30 and admission is free. (Niesel)
