the Statue of Liberty. Everybody thinks of the Statue of Liberty as the work of the sculptor Frédéric Bartholdi, and it is of course his design. But without ingenious interior engineering to hold it up, the Statue of Liberty is merely a hollow structure of beaten copper barely one-tenth of an inch thick. That’s about the thickness of a chocolate Easter bunny—but an Easter bunny 151 feet high, which must stand up to wind, snow, driving rain, and salt spray; the expansion and contraction of metal in sun and cold; and a thousand other rude, daily physical assaults.
