The thickness of the lines on the ruler

I think it’s always worth remembering that precision is not the same as accuracy.

For example, if I tell you it’s 413.793 degrees here in Portland, I am being very precise — but not accurate. If I tell you it’s dang hot here, I may be very accurate — though not precise.

We can be accurate without overworrying about precision. We can’t be precise, however, while shitcanning accuracy.

Because that would be an unreasonably hot day.
