It seems that mathematicians of Ancient Greeks switched from number theory to geometry after the experiences of Pythagoras.
By the way, what topics can I write about on the platform ProofOFBrain.io?
POB appears to be letting people write on any topic. There was a group of people who wanted to police POB. One of these POB-watchers downvoted a whale who was engaged in tag spam and the POB-watchers found themselves on the losing end of a down vote war.
I like writing posts on different tribes. If the post is about philosophy, i put it on POB. If it is about science or math, I put it on STEM. If it is about finance, I put it on LEO. If it is about economics, it goes on CENT. If I create an original drawing, i put it on CreativeCoin.
Political stuff should go on tribes like LASSECASH, POLITICS (which gives out the PAY coin), MEME (assuming the post as a meme-style picture) or INFOWARS.
