Perspicacious - mentally clear-eyed: mentally acute or penetratingly discerning. What a great word.
I've already been labeled Kepler the Acute, Kepler of the Long Reach, and Kepler the Moderately Handsome, which, funnily enough, gave birth to my most recent epithet: Kepler the Frequently Described.
At some point I'd like to add Kepler the Perspicacious. Unfortunately, in order for someone to label me perspicacious, people at large would need to know that word... Oh well.
