The Goal: A Process of Ongoing Improvement

"Purpose" is a scientific and educational book. Now these two concepts are used so often that their original meaning was lost in the fog of excessive servility and mystery. Like most serious scientists, I think that science has nothing to do with either the secrets of nature or the immutable truths. This is simply a method by which we operate with a certain minimal set of assumptions that can, through direct logical constructions, substantiate the existence of many natural phenomena. The physical law of conservation of energy is by no means true. This is just an assumption, effectively explaining a huge number of natural phenomena. It is impossible to prove the universal applicability of this assumption, no matter how many concrete examples of its validity you give. But this assumption can be refuted by a single fact that it would not be able to explain. But even such a refutation does not deprive the assumption of justice. It testifies to the need for another, more general assumption. This is how the law of conservation of energy was replaced by the more general Einstein postulate of conservation of energy and mass. Einstein's law is not true to the same extent as its predecessor.
