You can’t imagine how dirty our kitchen floor gets on a daily basis! The broom and the floor are very close friends. They meet each other once a day, ideally even twice. The result is some degree of cleanness for a couple of minutes or even hours (over night). There is just one peculiar thing that you have to understand. We assume, that the dirt in our kitchen is equally spread over the whole kitchen area (and beyond, of course). When Albert sees one of us brushing the floor, he quickly gets „his“ small broom. That means exactly, that he, after we have gathered the dirt together in one corner, he re-distributes it over the whole floor. The thought behind this must be genius! I am sure he thought that the dirt is not REALLY equally distributed and therefore always attempts to get a perfect Gaussian distribution here!
