Economist milton freidman: We can never prove sth; we can only confirm its existence.
But in mathematics, it seems that after the statement is proved, it is 100% true.
Statement1: If i wake up at 10a.m, i will get an A in that day's exam.
Is this statement true? I dunno. Can i prove this? This statement will be refuted on the day i get up at 10a.m but get a B in that day's exam.
Statement2: If n is an even integer, 5n is also an even integer. Sure we can prove this. Is it 100% true? It seems yes as it is derived from the axiom of real no. system. Will someone refute this statement by finding a counterexample?
So:
Maths:Proof
Physics,Economics:Confirmation
