Resonance

Resonance was a phenomenon that occurred when the matching vibrations of another object increased the amplitude of an object's oscillations.

In 2367, USS Enterprise-D's ship's computer quizzed Geordi LaForge, challenging him to "List the resonances of the subquantum states associated with transitional relativity… in alphabetical order." LaForge answered four out of five in the twenty seconds given to him – "asymmetrical, inverted, phased, stable" – but failed to state the last answer in time – "universal". (TNG: "The Mind's Eye")
