Description

Littlewood defines a miracle as an exceptional event of special significance occurring at a frequency of one in a million. He assumes that during the hours in which a human is awake and alert, a human will experience one event per second, which may be either exceptional or unexceptional (for instance, seeing the computer screen, the keyboard, the mouse, this article, etc.). Additionally, Littlewood supposes that a human is alert for about eight hours per day.

As a result a human will in 35 days have experienced under these suppositions about one million events. Accepting this definition of a miracle, one can be expected to observe one miraculous occurrence within the passing of every 35 consecutive days – and therefore, according to this reasoning, seemingly miraculous events are actually commonplace.
