wow "Expand your thinking"
sounds like someone's twitter account is getting a reference.
sorry, it's a youtupe account
the governor of Puerto Rico resigned and it really was about 'muh chat logs!'
his.
'point'?
a theoretical construct that doesn't really exist.
any algorithm that looks for a 'point', for example, must settle for a very small region of the measured space.
in order to get past the idea of 'point' being mathematical it's typical, in optics (or electromagnetics) to say 'source'.
there are no points, but there are sources.
