According to the laws of physics, order has a cost, in terms of the creation of some form of disorder somewhere else, as the entropy states. The paper considers examples taken from everyday’s life, and their empirical solutions. There exist exact methods for creating and maintaining order, found at the origin of artificial intelligence by Simon, referred to as linked lists. Unlike what is generally supposed erraticity is not a pure randomness problem, but rather must take into account actual bifurcations, possibly not reversible. Since we are interested also on the cultural side of mosaic, it is correct to start from persons whose life has been important, but erratic, with relevant turns in their activity, or in their long time fortune. The examples we give, should suggest the reader to look for other examples according to his own inspiration. An exercise, that is only sketched in the paper, is to look for the turning points that we can find in the history of landscape or in the history of towns. When does erraticity arise, how long does it remain undefined and subject to randomness, when becomes irreversible?
