Pure mathematics cannot be turned to warlike purposes

Evidence

Real mathematics has no effects on war. No one has yet discovered any warlike purpose to be served by the theory of numbers or relativity, and it seems very unlikely that anyone will do so for many years. — G. H. Hardy, A Mathematician’s Apology, 277
