George can do it. From: Friam <[email protected]> on behalf of Nicholas Thompson <[email protected]> Date: Sunday, June 15, 2025 at 11:59 AM To: The Friday Morning Applied Complexity Coffee Group <[email protected]> Subject: Re: [FRIAM] Entropy RE-redux
Marcus, Thanks for checking in. I think I can safely say that that is a thing I will probably never do, but you have reminded me that I ought to see if somebody has already done it in NetLogo. I am sorry that my original post was garbled. Here is an ungarbled version: Same setup as before. Cylinder with two plungers and a peggable slider at dead center. Lets fill our compartments with bbs of the same volume. Unpeg the divider. Now let's tap on the two opposite plungers with a series of blows of the same average magnitude but different skew in the distribution of magnitudes: a normal distribution for the left half, and a highly positive skewed distribution on the right. Will the divider move? As I think about it, I begin to wonder what is the best measure of central tendency to use in making a prediction. Am I correct that if it is the arithmatic mean, the barrier does not move, and if it is the root mean square, it does? How on earth would I decide which measure to move; I suppose we could look and see what happens to the bbs.
