Even though itās possible to design an oral thermometer that measures body temperature to a hundredth of a degree, thereās no reason to do so. In fact, 98.6 is overkill. 98 is enough information.
More digits donāt give us more information, they simply distract or confuse us.
The same is true for time. Knowing what happened in a one-second snapshot interval is useful for judging a horse race, but hardly interesting if weāre measuring interest in a new Broadway show.
Just because we can add more digits doesnāt mean that itās significant. We can intentionally ask for less.
