The term innovation derives from the Latin innovatio, the noun of action from innovare. The word first came into modern use in 1540 and stems from the Latin innovatus, pp. of innovare "to renew or change," from in- "into" + novus "new".

MEAN is definitely a mean molecule. It stands for monoethanolamine nitrate, which is an explosive used as a sensitiser in 'slurry explosives' (mixtures of ammonium nitrate, sodium nitrate, a gelling agent and water). Slurry explosives are sometimes used in mining and quarrying, but nowadays they are on various governments' watch-lists as potential terrorist weapons due to their ease of manufacture. I believe it's also used in small quantities as a fertiliser, and doesn't cost too much - so it's a favourite with mean gardeners.
