How Humanlike Was 'Ardi'? Nov 20, 2009
The summary in one of the Science papers, led by Owen Lovejoy of Kent State University in Ohio, argues that by Ardi's time, "the gluteal muscles had been repositioned so that Ar. ramidus could walk upright without shifting its center of mass from side to side" (unlike today's lumbering great apes), but a different interpretation of the ilium could change all of that. Despite the numerous images and descriptions put forth by the researchers, others are reluctant to take the reconstructions... (Scientific American)

A generation later Isaac Newton refined Kepler's law to say that the moon follows an elliptical orbit about the center of mass of the combined earth-moon system. Newton was aware that the sun and planets' gravity must also affect the moon, but lacked the theoretical tools to address this so-called "three-body problem.". (Burley South Idaho Press, ID)

Gay said that the hit should be applied at the runner's center of mass just below the rib cage in the center of the chest to direct all the force into stopping his forward motion. Missing that spot by too much, Gay said, "Causes the ball carrier to rotate around his center of mass, and he might not go down. The announcer would say, 'He bounced off him.' ".
