Hello Kari, I was sorry to see that your equanimity was affected by the problem of the balls in sacks. Let's see, here's the problem: << In a far-off land still relatively unspoiled by western influence, a wise monk carrying two sacks approaches his pupil. "In one of these sacks", says the monk, "are 10 white balls. In the other sack are 10 black balls. Never mind where I got them. I will randomly draw a ball from one of the sacks. If it is white, you will be enlightened. If it is black, you will remain forever in the dark." "Before I draw a ball, I will turn my back, during which time you may change the contents of the sacks by moving balls from sack to sack. When you are done, however, there must still be 10 white and 10 black balls total between the two sacks." Is there any way for the pupil to increases his chances of seeing the light? >> As I have already posted, the answer to this riddle is: "yes, there is a way" I know, I am being cute, you probably want to know how he can increase his chances. Well, much like my old astrophysics professor, Dr. Bergerac, expounded, it just so happens that there is not just one way to do this but myriad ways which I have discovered. That you did not manage to stumble onto any of them is a shame, but still, you were the only person (besides myself, a former applied physics candidate), who seems to have been bothered by this seemingly non-literary challenge, which is probably not solvable using post structural or theological methodology, sarcasm or earnesty. A sense of humor would help, so Matt S. gets a tip of the hat. In the great tradition of internet humor, then, let me present the top 5 ways in which the pupil can increase his chance of seeing the light: 5. glue all the black balls to the bottom of the sacks 4. paint all the black balls white (the formerly black balls will still be in the sacks) 3. place all the black balls into one sack, knot it, and place it together with the white balls into the other sack 2. place the white balls into the two sacks, and place the sacks on the ground with the black balls in between them. The black balls will still be "between the two bags". and finally, 1. to "increase his chances of seeing the light" he can turn on a lamp I admit, that some of them are "cheating" a bit, but you get the idea, which is the point of this whole excercise - to get ideas. Have fun, Mattis
