The Way We Work
336 pages; HMCo
At last, smooth-running infrastructure! David Macaulay's The Way We Work, written with Richard Walker, brilliantly explains how it all hangs together—flesh, bones, muscles, nerves, not to mention some pretty snazzy organs, in that well-oiled machine we call the human body. If you're not amused by a drawing of a chorus line of connective tissue, you probably need to have your eyes examined.
