&gt; You can believe or not in some physical reality to math (I happen to)<p>I&#x27;m not so sure. Is there any evidence that the value of any physical quantity is an irrational number?<p>Math was originally inspired by physical reality, but I&#x27;m not sure it&#x27;s so closely related that the concept of the Axiom of Choice being &quot;true&quot; even means anything.
