This statement was inspired by the observation that so many aspects of the physical world seem to be describable and predictable by mathematical equations to incredible precision especially as quantum phenomena. But quantum phenomena have no...

They seem to be completely describable by only numbers and their behavior precisely defined by equations. In this sense, the quantum world is made of math. So does that mean cats are made of math too? If you believe the mathematical universe hypothesis, then yes.
