But we do that all the time. Whenever something new comes along, either new terms are invented or old terms are adapted/reinvented. Just some examples: -ping, which came from the operation of sonar and now is also a ICMP command for testing connectivity -boot, which now means "start the device" but comes from "bootstrap program" which in turn comes from the phrase "pull one up by one's bootstraps" -switching, which went from railroad to telephony to networking -aircraft, wow, do we even want to go here, with port/starboard, rudder, pilot, hull, cockpit, turret, etc. all being borrowed from nautical terminology, and some of those, like turret, were in turn borrowed and redefined from earlier times. So the idea that "impulse" could have a broader--or even completely different-- connotation than the classic Newtonian one is, to me anyway, entirely reasonable.
