masse (iou) and time dilation (sh)


masse (iou)



masse adjective & noun. L19.
[French, pa. pple of masser play a masse stroke, from masse MACE noun1.]
Billiards etc. (Designating) a stroke made with the cue more or less vertical, so as to impart extra swerve to the cue-ball.

time dilation (sh)




In the theory of special relativity, the "slowing down" of a clock as perceived by an observer in relative motion with respect to that clock.

Time dilation becomes noticeable only at speeds approaching that of light and has been accurately confirmed by the apparent increased lifetime of unstable subatomic particles traveling at nearly the speed of light and by the precise timing of atomic clocks carried on airplanes.
