About the Book
The bridge collapsed on November 7, 1940. The wind was 42 miles per hour, well within design tolerances. The engineers had accounted for static wind load. They had not accounted for aeroelastic flutter.
In Seattle, Margaret Chen runs 500 expense claims through a test before she reads a single receipt. She expects 151 of them to begin with the digit 1. She finds 95.
In a bar booth, Alex draws three doors on a napkin, a car behind one, goats behind the other two, and says, “But that’s obviously wrong.” In a pale green chair under humming fluorescent lights, a patient holds a manila envelope from a test that is 99% accurate. In the Hall of Mammals, a two-gram Etruscan shrew faces a four-thousand-kilogram elephant across the room. Their hearts beat a remarkably similar number of times before they stopped. Seven riffle shuffles. Twenty percent of a closet. A spider’s web strung between fence posts, invisible until the dew.
Each of them stands inside a structure they cannot see. It is already deciding things for them: which search result appears first, which digits a liar reaches for, how many heartbeats a life gets.
Behind his house, a man pictures the lily pads doubling, day by day, across his pond. For twenty-five days it looks manageable.
On day 29, half the pond is still open water.
