If some guest from another world or dimension gave a talk to a roomful of the world’s prominent scientists, and he wrote on the board the Unified Field Theory, pointed out a thing or two that our world hasn’t figured out yet, and then quickly erased it; What are the chances, barring any use of cameras/phones that you or anyone or collectively the whole room would be able to reconstruct the Equation from memory? Or would most scientists at that level “have it” as soon as they saw it?
