I am teaching mathematics. And I want to collect as many evidences as I can to let my students know that mathematics is very important.
Accidentally I got a quote from Napoleon as follows.
Napoleon used to say that (quoted from this site):
there cannot be a great nation without great mathematics.
Did Napoleon say that?
What is the evidence of the correctness of Napoleon's statement about Mathematics above? In other words, was Napoleon right on his statement at that time (not necessarily up to now)?
