Couch no slouch

John Couch Adams was the first to predict the existence of a planet beyond Uranus, (Neptune). He did this purely through the application of mathematics. A French astronomer had the same conclusion and they published at the same time.

He did this at age 24. And he was a Cornishman, born near Launceston. #Waves black flag with white cross on it :P#

Happy anniversary, Neptune & Couch.
