No. The first is a theory. It's still being tested. Evidence does exist, and can be verified by empirical analysis. And still, if new evidence is presented that contradicts that theory, then the theory can be revised or discarded as appropriate... unlike a superstition, which simply IS.
The second is a mathematical system, which works consistently according to the postulates and constructs governing mathematics. Additionally, evidence supports that sums can be added to express total quantity. If I have two apples and two oranges, and I put them into a basket, I can SEE four fruit in the basket. Other people can verify the quantity. Same thing when adding vectors in physics - additive properties of quantities are consistent within abstract mathematics AND the physical world.
The idea that other minds exist is substantiated by the fact that other people exist, and they do not always behave as I expect them to behave. Things happen beyond the ability of my mind to predict or imagine, and therefore must have an external source. The realm of philosophy is sticky, but nobody claims that their philosophical postulates are the absolute definition of the universe. If they do, they're generally considered to be mad... unless they're religious. Then they get a green flag. Philosophy does have an element of superstition, but good philosophy is based on observable phenomena that can be verified.
