I am overdue in recognizing Sidney Harris (not a relative) in "Hal's Picks". His cartoons are always very funny, and he surely must do more of them about subjects in science than anyone. You have surely seen his work in American Scientist, Playboy, or the New Yorker. I have had his "What's So Funny About Science?" and "Einstein Atomized" on my shelf for many years, and "Einstein Simplified" is a newer (although not very new) favorite. Topics are spread over biology, physics, mathematics, computer science, chemistry, and even a few on medicine, but there are not quite as many chemistry cartoons as physics or biology. I can't believe that we are less easy to make fun of.
