Pop quiz: How many scientists can you name? OK, trick question—Einstein’s dead and Mr. Peabody is really a cartoon. That pretty much leaves Carl Sagan as the reigning idea man in American popular culture. Even though he’s subject to the occasional attack of raging pomposity (viz. the hissy fit over Apple naming a prototype computer after him), his ability to make quarks even remotely understandable should not be discounted. Sagan discusses his “overarching vision” about “the wise use of other planets” and his latest book, Pale Blue Dot: A Vision of the Human Future in Space at 8 p.m. at the National Air & Space Museum’s Langley Theater, 6th & Independence Ave. SW. $18.
