The new Wordless Diagrams (Bloomsbury Publishing, $15, www.amazon.com) has all the marvel of 19th-century stop-action photos and the charm of Edward Gorey’s detailed drawings. Have you ever wanted to know the right way to do a reverse inward pike from the high diving board, administer CPR, or build a sand castle? Graphic designer Nigel Holmes illustrates these actions and more in his whimsical picture book for adults. You’ll never think of catching a spider in the same way again.
