Excitation

Encyclopedia : E : EX : EXC : Excitation

Excitation is the amount of energy (energy in a general sense, not energy as defined in physics) that something or someone has. In physics there is a specific technical definition for energy level which is why the word excitation has been chosen for the general case. An atom can be excited to an excited state.

In the physical world temperature is indicative of the level of excitation.

At higher levels of excitation processes usually proceed faster.

Brian Wilson of the Beach Boys coined the pluralized version of excitation in his hit song "Good Vibrations." In which he sang, "I'm picking up good vibrations, she's giving me excitations." Brian Wilson uses the term 'excitations' to convey his feelings of sexual arousal.
