I stay up way too late watching YouTubes via its streaming app on my cable TV service. It is addictive. There is always something else to watch. It is hard to stop.
And then when I finally shut the TV off last night, I got out a pad and pen and tried to estimate the square root of two by trial and error. I picked a number X, squared it, and if X^2 < 2, it was a lower bound, else it was an upper bound. Once I bounded it, I tried numbers inside these bounds, and repeated. I homed in on the true value. I did it out to 4 decimal points then went to bed.
