The problem isn't that true mathematical relationships don't exist it's that false ones do too, and the only way anybody has ever been able to separate true statements from false statements is by using matter that obeys the laws of physics. And that is my explanation for why INTEL makes microprocessors out of silicon and not out of definitions and theorems; Bruno, you have no coherent explanation for that fact.
