Mathematics is Turing-complete, so proper formula with right magic constants can separate dogs from cats (see neural networks for example: they are pure mathematics). However, I had belief in Theory of Relativity for my whole life until I saw three effects: double slit experiment at macro level [0], magnetic foam at the edge of Solar system [1], and Sagnak in _linear_ motion [2]. Sorry, but I lost my belief and I want explanation, not a magic formula.
