I’m very glad you record this podcast.
Aleksandra, Poland

Wed, 04 Jan 2012 05:07:08 +0000http://mathfactor.uark.edu/?p=1367#comment-929I couldn’t figure the connection between 503 and the first four primes, until I accidentally cubed each of them and found that 503 is the sum of all 4 cubes! About the M&Ms – the first swap of 50 M&Ms makes each pile (bag, box, etc) 90% as pure as it was before (red becomes 90% red and blue becomes 90% blue). At this point I assume the M&Ms are uniformly mixed in each pile. The next time, 81% of the original color is kept but 10% of the original color which was taken away the first time is returned so the pile is 82% its original color. This continues with the colors getting more and more evenly mixed until about 20 swaps when each M&M scoop is, on average, half red and half blue. This is exactly the same as the old puzzle about moving a teaspoon back and forth between a barrel of water and a barrel of wine (each barrel of same capacity) and eventually both barrels are half water and half wine as near as you can measure (within a few micrograms). I can’t come up with an equation to measure how fast this occurs, however.
