So if the brain is just doing some sort of computation then do you also agree with the statement that any flow of fluid (river etc) is just solving fluid dynamics differential equations?
- red75prime 8y agoFlow of fluid is governed by physical laws, for which Navier–Stokes is an approximation. Brain is governed by physical laws too, of course. But its structure facilitates processes which can be described as information processing. If water fails to solve Navier-Stokes, we change the equations, if a human fails at reasoning, we correct the human.
- ankurdhama 8y agoMy point was that we use mathematics to model physical phenomenon and by definition every model is an approximation of the phenomenon which means that you cannot say that the phenomenon is actually doing what the model says. Instead we say that the model is useful only to answer certain set of questions to certain degree of accuracy.
