When living with other human beings, it can become very difficult
to make sure everyone takes care of their respective dishes. In
fact, while everyone may agree on a strategy and plan, the
agreement are generally forgotten or ignored within a few weeks. At
college, I live in a flat with three other geeks. We have all
agreed not to let dishes go unwashed for more than 24 hours. With a
few minor exceptions, this keeps our kitchen fairly tidy. In fact,
it may even be that the messier bits of our kitchen are caused by
the food-preparation processes and their byproducts. Still, having
visited the kitchens of others, we are constantly reminded of how
nice it is to have a clean space. In fact, our success was pointed
out by our friend Fred who came over last week to play some
StarCraft. As some of us
went to grab our dishes to eat some of the veggie stir fry we had
just prepared, Fred pointed out the reason for our continued
cleanliness: One man, one bowl. The inner workings of the system
are profound yet elementary. Every person, being a poor college
student, has a severley-limited selection of dishes. Therefore, we
may assume they will most likely default to using the most
versatile dish, which is none other than the common
bowl), the most often.
As such, there is one bowl per person. While this may seem
insignificant at first, consider the implications. First, everyone
is responsible for one piece of dish ware which makes keeping one’s
implements clean a much more manageable task. Second, because
people need to eat multiple times a day, the dish must be used
multiple times a day. In order to use the dish again, it must be
washed. This heuristic is still dependent on personal initiative.
The time, T, a dish spends in a non-clean state can be defined by
the summation
where n is the number of meals per day, m is the duration of
the meal, b is the time between the end of the meal and the
beginning of the cleaning phase while c is time between the
beginning and the beginning of the next meal. This means that if a
person puts off washing the bowl until it is needed for the next
meal, then the bowl will spend most of it’s time in a non-clean
state. However, even with everyone leaving bowls unwashed until
required next, the largest amount of dishes waiting to be washed
never exceeds the number of people eating in a 24-hour period.
Shockingly simple, yet startlingly effective.
