I'm a guy who knows lots about stuff and things.


Reminder to self: the spectrometer article is pretty punk. It needs a good picture and description of a typical two-mirror grating spectrometer. Also an article on échelle spectrometers would be good. They're mentioned several times in the Wikipedia, but never described.

Another reminder: etymology of star names seems like it could use improvement.
