PI is not something that can be delivered? If you're trying to understand why constants have the value they do then you'd need to know more about physics and not mix up math and physics. Math is used to help understand the physical world, but math transcends physics. The universe need not even exist for math to still be whole and complete. Admittedly we probably wouldn't be in much of a position to appreciate it without a universe around to show how clever it all is. What you're alluding to is the anthropic principal.

You misunderstood me a bit. I gave PI as an example of constant that _can be_ delivered and it is well-understood why it has a certain value. I agree this wasn't a good example, PI is indeed mathematical constant, although it appears in physical equations.
