Balancing ActWould appreciate any help with this one. #2 20110808 15:24:23
Re: Balancing ActHi fillyfog; In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #3 20110808 15:31:42
Re: Balancing ActHi fillyfog, "Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  Buddha? "Data! Data! Data!" he cried impatiently. "I can't make bricks without clay." #4 20110808 15:47:43
Re: Balancing ActDon't think it matters what kind of weights they are, the numbers just have to be the same on each side so that scale is balanced. Last edited by fillyfog (20110808 15:50:08) #5 20110808 15:49:09

Re: Balancing ActAll weights have to be used. #7 20110808 15:54:42

Re: Balancing ActThis is the solution from the book. #9 20110808 16:12:17
Re: Balancing ActIf that is a solution then I am computing the weights on the second level differently. In mathematics, you don't understand things. You just get used to them.

Re: Balancing ActCould you explain how you got each of the numbers? Last edited by fillyfog (20110808 16:26:35) #11 20110808 16:29:51

Re: Balancing ActJust if you could explain how you got your numbers: 27 + 10 + 16 = 7 + 6 + 4 + 18 + 18 #14 20110808 16:40:39

Re: Balancing ActIsnt' the 4 weight considered to be on the left side of the scale. #20 20110808 16:58:28
Re: Balancing ActThen you can see if you put that four on the left, there answer is not solution. Try it. In mathematics, you don't understand things. You just get used to them.

Re: Balancing ActThanks a ton for explaning the math in the puzzle for me. #22 20110808 17:16:07

Re: Balancing ActGoing back and checking the book's solution with what I now know, I think gAr's solution 9 7 8 4 2 5 6 3 is the one they should have gone with in the book instead of the 9 5 8 4 7 2 6 3. #24 20110808 18:55:56
Re: Balancing ActHi;
When you showed the book solution, I just adjusted my method to how they were figuring the second level. I did not have their answer either. In mathematics, you don't understand things. You just get used to them. I have the result, but I do not yet know how to get it. All physicists, and a good many quite respectable mathematicians are contemptuous about proof. #25 20110808 19:22:34
