      Well, (shedule for next test at the bottom of page) Congratulations once again to PJ for his quick soultion of the last problem. I'd love to see his workings for the problem, but the result was the only response required. So I guess well all be in the dark as to how he solved a problem that has been bafflling math chaps for milleniums. So it can now be written in stone as a testament to humanities achievments "PJ did Pi at CP". Also so if you know some one good with number, Math. It might pay to inform them of these activitie din the SoapbOx. :-) I'm in a slight quandry as to which will be the next problem. My specs for the problems are that they should be 1.)solvable by people who are prepared to apply themesels; 2.) that the answers will not be found useing the Big G or mathworld.com; 3.) When the answer or solution is shown, participants will think (why did'nt i thing of that as its darn obvious. (repember if the problem looks difficult you have been suckered) Anyhow still remaing without a CP solution is eggs ---- eee If anyone wants a paticular challenge of want to offer one please let me know, or just post it ! Next Ramathdom questuin will be 1n 100 to 124 hrs fro this posting. Regardz Colin J Davies

            How about logic problems that use elegant maths instead of problems of the form "Let's try every different permutation and mathematical combination of these letters and numers till we find something that might be right" Let me throw one out (this is an oldie so is probably know by some here) Take a look at the diagram here. It shows a flat area of land surrounded by a moat which is surrounded by flat land at the same level as the inside piece of land. The moat is 1 unit wide and filled with crocodiles. 2 parts: 1. Given 2 boards 0.9 of a unit long, how can you create a bridge to cross the moat. No ties, no tools, no nothing. Just two boards. 2. Is it possible to create a bridge using boards 0.5 units long? If so, how many boards are needed? Assume: o The boards are only wide enough to walk along. o They are sufficiently strong to hold whatever weight is needed o They are non-slip boards o They are a light brown colour o The crocs are hungry cheers, Chris Maunder

              Gosh, didn't know you felt that way. :-) Any problems I present I try to make both original and obvious when solved. My prefernce with problems is those that when you see the solution you feel so silly for not thinking out of the circle square. :-) :-) Are the moat and land area perfect square shapes ? Because in the image they appear a bit distorted. Regardz Colin J Davies

                1. The moat is .5 units wide. .... (Outside - Flat area) / 2 so 2 .9 unit boards can be used easily with one on each side. 2. considering in the real number plane that boards of .5 units would not be engineering style sound. A .5 unit board could be placed diagonal on any corner of the outside and another used to connect across to the morner of the flat area. So 4 boards could be used. Or you could just walk around the outside. Regardz Colin J Davies

The bridge idea won't work because you couldn't get 1 unit of distance out of it (the sum of 2 sides is always greater than the third side; 0.5 + 0.5 = 1 so we know that the distance spanned will always be less than 1 unit. AH! If you have two wooden boards end to end, and hold them in the water; they should swell a little, thus making them slightly larger than 1 unit when end to end; the pressure resulting from fitting them in between the moat walls might hold the boards.

                          How deep is the moat? Put one end of a board into the water a little over half way, with the other end on land. Walk down the non-slip board with the other board in hand and place one end on the board you are standing on and the other end on the opposite bank. For .5 unit boards, use 3 like this: \-/. The middle board would rest on the other 2, just out of the crocs' reach.

                                How deep is the moat? Put one end of a board into the water a little over half way, with the other end on land. Walk down the non-slip board with the other board in hand and place one end on the board you are standing on and the other end on the opposite bank. For .5 unit boards, use 3 like this: \-/. The middle board would rest on the other 2, just out of the crocs' reach.

                                What's holding the board down? You step along the board and it will tip over into the moat. As for using 3 boards, how do you get the 3rd board on the other side of the moat, and how do you ensure it's secured so it doesn't flip over when you put weight on it? cheers, Chris Maunder

                                  put the boards like this:

                                  --\-----+
                                  \ |

                                  -+ \|
                                  +

                                          couldn't work 'cause hypotenuse (sp?) is biggest side, minimum board length with this setup would be sqrt(2)/2? [edit] that's wrong minimum board length, can't be bothered to work the proper one out :-D got packing to do... [/edit] -- Andrew.
