About the Book

Maria steps into the elevator on the fourteenth floor, coffee in hand, and presses L. The car begins to drop. The surface of the coffee stays mirror-flat, and by everything she learned in high school it should be climbing the walls of the cup.

On I-280 the fog is so thick my headlights barely reach twenty feet. I follow the white line toward the Highway 92 interchange, turning the wheel about two degrees per second while the road tightens beneath me, and the cup on my dashboard doesn’t budge. My grandfather drove the old highways. “Coffee would go flying,” he’d say, miming the lurch against the passenger window.

In a crowded restaurant, one pressure wave hits your eardrum. Glasses, chairs, music, a dozen conversations, all folded into it. You pick out your mother’s voice in milliseconds. Stare at a red square for sixty seconds, then look at white paper, and you will see a green that exists nowhere in the light. A single rod cell in your retina has a twenty-two percent chance of answering one photon.

Euler worked part of it out in 1744. Fourier, in 1807, was thinking about heat. Weber was lifting a 30-gram weight and a 31. None of them were thinking about Maria.

She reaches the lobby. The coffee is still perfect in its cup.
