The arrogance of people who try to claim that Pi has nothing to do with the business cycle is really amazing. They assume that a business cycle means we have no free will. They are ignorant of the fact that collectively we display mob or herd behavior. That does not negate you individual ability to participate with the herd or understand this is just a herd reaction as in financial panics. Of course we have FREE WILL, but the means we have the capacity to wise-up and move counter-trend to the majority. This does not turn everyone into a mindless drone.
Pi is turning up now in various science fields. It os a incredible important discovery that warrants our attention.
