      英文詞源


      ballistics (n.)
      1753, "art of throwing; science of projectiles," with -ics + Latin ballista "ancient military machine for hurling stones," from Greek ballistes, from ballein "to throw, to throw so as to hit," also in a looser sense, "to put, place, lay;" from PIE root *gwele- (1) "to throw, reach," in extended senses "to pierce" (cognates: Sanskrit apa-gurya "swinging," balbaliti "whirls, twirls;" Greek bole "a throw, beam, ray," belemnon "dart, javelin," belone "needle"). Here, too, probably belongs Greek ballizein "to dance," literally "to throw one's body," ancient Greek dancing being highly athletic.
