This is a nice suggestion. My category theory class suggested "nadir" when I asked "what is the dual of the apex of a cone?" But then I should have dualized the dual notion. #CTiChttps://twitter.com/BarbaraFantechi/status/958741921022689280 …
'apex'/'imulex' for the co(cone) internally, and 'zenith'/'nadir' for the collective properties of many co(cones). then azimuth and declination acquire category-theoretic meanings, @johncarlosbaez

poles/equator: geometrical spheres apex/imulex for a category theoretic co(cone) zenith/nadir/azimuth: for category theoretic spaces containing lots of co(cones).
