Sorry to be a party pooper, but I find the story of Jason Padgett (the guy who ‘banged his head and become a math genius’) completely unconvincing. From the video that you cite, here is the ‘evidence’ that he is ‘math genius’:
He tells us, with no context, ‘the inner boundary of pi is f(x)=x sin(pi/x)’. Ok!
He makes ‘math inspired’ drawings (some of which admittedly are pretty cool but they’re not exactly original) and sells them on his website
He claims that a physicist (who is not named or interviewed) saw him drawing in the mall, and, on the basis of this, suggested that he study physics.
He went to ‘school’ and studied math and physics. He says started with basic algebra and calculus and apparently ‘aced all the classes’, but doesn’t tell us what level he reached. Graduate? Post-graduate?
He was ‘doing integrals with triangles instead of integrals with rectangles’
He tells us ‘every shape in the universe is a fractal’
Some fMRI scans were done on his brain which found ‘he had conscious access to parts of the brain we don’t normally have access to’.

good to know thanks for flagging!
