If there's an ultimate fixed law of physics - of the whole universe, then everything is already determined by the law. If the law is the only and true, then how and where's the evolution - the mistakes and accidental incidents in nature coming from?

If the ultimate physics law is describable in math language, then it's a program, an equation, a calculus, anything math has fixed output, even a random set is calculated in predictable way with explainable results. Predictability is timeless. Math is timeless. Math is the perfect model.

Yet nature is full of imperfectness and surprises. This capability of generating genuine organic randomness and mistakes must be imbedded in the fundamental level of existence - no matter it's particle or other fundamental form. --What if there's no such a thing as fundamental? What if this deductionism mind model just another math thinking? What if one travel out of earth getting shot into space and in the deep universe after passing solar system and galaxies, what he reached as the large scale univer structure is a microscopic cell?

If the true law is change itself, then what's the pattern of change? By saying pattern, it's again an attempt looking for something fixed and predictable. If the result is nothing fixed, then could the law still be describable? In another language instead of math - the fixed timeless one, as the natural history is time-bound? If taking math language as nature language, a language could describe a scent, the mechanism of smell, yet it cannot decribe the very sensation when one smelling the scent. What if the 'fundamental law' is like the sense of a scent? Talking about scent, cyanide and almond has the same smell. In fact, we smell different smell is not because different matters has different substances, but smell is just the molecule(quantum level) vibrate in different frequencies, what we call as scent is just different form of vibrations like sound and music, it has nothing to do with what kind of attoms they are...
