Berta taps the slate. A new graph overlays the old one. This new curve is flatter and wider. The peak has shifted to the right (higher speed), but it is lower in height. And the long tail on the right—the "fast spore" tail—is now longer and fatter.
Carlos stares at the curve. "The line starts at zero on the vertical axis when speed is zero," he says. "So… none? Every spore is moving at least a little?"
"Exactly," says Mya. "You can’t tame the distribution. You can only give it more energy and watch the tail grow."
