Some people have a lot of things they’d like to do, but I only have one and it looks probably naive to most of you.
Here it goes.
If I be rich, I would set up a foundation to promote Science for the average man (AKA popular science). Making scientific knowledge accessible to the average Joe is of capital importance: make Joe understand what what happens around us and what scientists are doing and maybe 10% of Joes would pursue further knowledge, therefore becoming scientists themselves.
I am particularly interested in Mathematics and Physics, although I do not disdain any subject which could be tested by the Scientific Method. That leaves Psychology, Sociology and the so-called “Social Sciences” out (btw, I’m still trying to find what “science” there is in “social sciences”, no pun intended).
