Frisbee: [20] The name of this spinning plastic disc had its origin in a catching game played in Bridgeport, Connecticut in the 1950s. The participants were no doubt not the first to notice that an aerodynamically volatile flat disc produces more interesting and challenging results than a spherical object, but it was their particular choice of missiles that had farreaching terminological results: they used pie tins from the local Frisbie bakery. The idea for turning the dish into a marketable plastic product belonged to Fred Morrison, and he registered Frisbee (doubtless more commercially grabby than Frisbie) as a trademark in 1959.

dynamic (adj.)youdaoicibaDictYouDict
1817 as a term in philosophy; 1827 in the sense "pertaining to force producing motion" (the opposite of static), from French dynamique introduced by German mathematician Gottfried Leibnitz (1646-1716) in 1691 from Greek dynamikos "powerful," from dynamis "power," from dynasthai "to be able, to have power, be strong enough," which is of unknown origin. The figurative sense of "active, potent, energetic" is from 1856 (in Emerson). Related: Dynamically.
