(262) It's an important step in uncovering the exact length of a Saturnian day, a conundrum that has perplexed planetary researchers for years.

(263) Reference efficiency of a pair of gear drive without planetary motion is the base to calculate efficiency of the whole planetary gear train.

(264) The principle straightness error of cutting square in work-pieces can be controlled by choosing a suitable pitch diameter of the planetary gear in the machine tools.

(265) Newton helped define the laws of gravity and planetary motion, co-founded the field of calculus, and explained laws of light and color, among many other discoveries.
