Illustration of the Movements of the Wok and Rice during Four Phases of a 0.322-second Cycle (image) American Physical Society Share Print E-Mail Caption Illustration of the movements of the wok and rice during four phases of a 0.322-second cycle: (a) The chef tilts the front end of the wok up while moving it backward to catch the falling rice. (b) The wok is at its farthest point from the chef (with zero translational velocity); most of the rice has landed. (c) The wok is pulled toward the chef as the front end is tilted down. (d) The back end of the wok is abruptly lowered leaving most of the rice airborne. Credit Ko and Hu Usage Restrictions Reporters may use this image only with appropriate credit.
