Of course, there is the complications of different wearing on different coins affecting their balence, air currents, if the coin and hands were dry, wet, oily, etc.
Chuckling, interesting but when you think about it, not surprising that identical flipping motions would tend to produce the same results in a lab experiment. With identical initial forces, the flight and rotation should be classical physics, or almost.
But outside the lab, all the other stuff that get thrown in.
And don't forget the possibility (ok, slight) of parapsychic (telekenisis for obvious one) influences. ![]()
Looks like a great weekend in the future in eastern NC, hope is the same your way. And coincides with my long weekend (every fourth week) of shift rotation. I don't do much outside, but still like nice weather.

One of the classic physical examples of an unbiased random physical process is the coin toss. Tossing a coin is perceived as such an unbiased process that we even use it for 'important' things like deciding the beginning of sports games. We even say that something unpredictable is a 'toss up'
It turns out that coin flipping may be random, but it is not unbiased. The side of the coin that starts out on top is slightly more likely to finish on top. Hear about it at NPR : All Things Considered for Tuesday, February 24, 2004 (scroll down to The Not So Random Coin Toss (the audio link is not active yet, but should be later this evening). There is some text information at NPR : The Not So Random Coin Toss and there should be an audio link there later on.
