Eternal requirements or: fundamental principles So the question arises: if everything is in a constant state of flux, how can we measure the direction and speed of change? How can we tell temporary spikes from structural breaks? How can we assess the change and determine what actions we should take?

The mathematician Archimedes said: “Give me but a firm spot on which to stand and I shall move the earth.” Of course, this statement refers primarily to the functioning of levers. After all, Archimedes was also an engineer. However, the sentence is also open to metaphorical interpretation: We need a firm spot for measuring and controlling the movement of something else.
