Even though itβs possible to design an oral thermometer that measures body temperature to a hundredth of a degree, thereβs no reason to do so. In fact, 98.6 is overkill. 98 is enough information.
More digits donβt 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 weβre measuring interest in a new Broadway show.
Just because we can add more digits doesnβt mean that itβs significant. We can intentionally ask for less.
