The colloquialism "quantum leap" has uses beyond conversation. It describes atomic orbital transitions as electrons "leap" from energy level to another and in the process they either absorb or energy in the form of photons. "Quantum leap" is also used as a figure of speech, a short hand metaphor in language. The idiom may connote a change in something's character, a greater change in energy or excitement or even a "leap of faith" or "jump to conclusions". In my chemistry class, the notes had contained this phase when describing the phenomenon and because the notes somethings took on a conversational tone, I could not confidently differentiate between the two cases. Perhaps this is proof that science is becoming more mainstream, maybe I'm lunatic but believe that understanding many things enriches our involvement with study, that nothing is truly separate. In this way it may be important to know this trivial details.
