A second Galilean revolution?

In the history of sciences, some apparently independent questions often have received the same answer. For example, the questions “What does make apples fall off trees?”, “What does make planets revolve around the Sun?”, “What does make matter hold together in a star?” all have received the same answer: “gravity”. When this happens, we can say that the concepts used in this answer structure a field of knowledge. For example, the concept of gravity structures mechanics. Throughout history, many questions could receive a satisfactory answer only after a structuring concept has been discovered, often in the attempt at solving another problem. For example, the discovery of the concept of electron has permitted to give a satisfactory answer to the question “What is electric current?”, but it has been discovered attempting at answering the question “What are cathode rays?”. It seems that nowadays the concept of algorithm permits to give satisfactory answers to many questions that had so far received only unsatisfactory ones.
