My own photo of a lighthouse over the curvature of the earth has been given the math teacher treatment.
I’ve been meaning to do a decent analysis of this one for a while, hopefully I’ll get some better photos and video this winter of sugarloaf point lighthouse Australia.

A huge thanks to Keigh see for help with this one.
