Milk production on a dairy farm has slowed down…

Management needs to figure out what’s going wrong, so they hire three consultants. A psychologist, an engineer, and a physicist. The psychologist spends a few days wandering the fields before returning to the farmer and saying “The cows are stressed tf out. Give them a window for natural light and more room to move, and they’ll make you more milk”. The engineer studies the dairy equipment for a few days and writes up a report. There are major sources of inefficiency that are bottlenecking capacity. Replace some of the tubing, and production will increase by 15-30%. The physicist spends months and months on the problem before finally publishing his perfect solution. Unfortunately, it only applies to spherical cows in a vacuum.
