An example of how the powers of the direction of the scientific academy generate difficulties, is the example of Newton against Leibniz. In that Newton was the dominant management system, and that the management was humiliated, and insignificance for those who are not dominant. In fact, Leibniz can only be reconstituted after Newton's death, when the dominant force loses its strength. In any case, Leibniz was remade, and calculus was finally demonstrated as an important tool for science.
