Here once again are the most innovative print and electronic infographics—“the full spectrum of the genre—from authoritative to playful” (Scientific American).   ROBERT KRULWICH is the cohost of Radiolab and a science correspondent for NPR. He writes, draws, and cartoons at Curiously Krulwich, where he synthesizes scientific concepts into colorful, one-of-a-kind blog posts.
