Thanks. Same as the poster. But some “horrible” memory did meet me as I did math stat. Within 1/2 hour the lecturer tried to do a proof of central limit theory using an assumption that one can draw sphere to fill up a 3D space. Reading this does frighten me to a great extent at the same time appreciate what humanity have reached for doing such apparent “useless” things. Public goods are hard as it might look useless but unlike private goods it can be consumed and reuse many times. And some may find use of matrix in AI, number theory and geometry in encryption ... all because it is a public good that can be shared.
The trick whoonearth waste their life to create the first and develop later such “useless” things.
