Making sense of the irrational

This computer claims that the square root of 2 is exactly 1.414213562373095048802. If I tell it to multiply that number by itself, I get 2.000000000000000000000.

I went for a long walk today. God, I'm tired.

There are red-eared sliders in Jamaica Pond, young ones. That means there is likely a breeding population there. The red-eared slider is a turtle native to the Mississippi Valley; supposedly it can't breed this far north, but methinks otherwise. The turtles in the pond, and others I've seen in the Muddy River and the Charles, are likely the descendents of escaped pets.
