If mathematics are physical in the sense that our neurons process any mental formulation and logic, then that means that math is not merely abstract, but also materially manifest. Could a certain chain of mental processes affect the world through EM waves? The logic and thought processes that occur when mentally solving an equation is repeatable and must be somewhat uniform from mind to mind to a higher degree than the understanding of sentences.

Anyway, my question is, would we possibly be able to alter the physical world in a tangible and noticeable way by following a set pattern of neural activities?
TL:DR: Can we do magic with our brains?
