I hope I'm not misusing or abusing our network, but I'm hoping some one of you may be able to help me on a project. Before I start here's something more in the math-fun spirit. I'm offering two hundred bucks ($200) for a solution of the following Nim varient. There are 4 piles, ordinary Nim rules, the only difference being that the game ends when three of the four piles are empty. To get down to business, I've received a small grant from the Sloan Foundation to look into the possibility of creating an on line Museum of Mathematics. Yes, I know there are lots of very nice mathematical sites, some belonging to members of this group, that already exist, (and I'm eager to learn about more of them) but this project is a little different. Primarily, my exhibits must be highly interactive like this link from the San Francisco Exploratorium (which unfortunately has nothing to do with mathematics). http://www.exploratorium.edu/exhibits/mix_n_match/ In fact I what I'm trying to make is a sort of on line mathematical Exploratorium, which will give you an idea of the intended audience. (I thought of calling it The Mathematics DiscoverySite.) The present modest aim of the project is to create two or three high quality, that is to say, "cool" prototype exhibits. The theory is that if these are sufficiently impressive then other members of the math community who are currently creating things on their own web sites will want to think up and contribute exhibits, and in this way the Museum would continue to expand and evolve over time. Last year with the help of two bright undergraduates we started on this prototype project. Due to limitations of time and resources we didn't get very far. In fact the main lesson from the links below is that they show what not to do. Nevertheless I think the ideas were good. The first exhibit is pure math, illustrating the Glur-Hadwiger Theorem which says that any two polygons of the same area are "equidecomposable" and moreover the corresponding pieces in the two dissections are congruent either by translation or central reflection. This allows for lots of clicking and dragging, animation etc. as you can imagine. http://mathmuseum.math.berkeley.edu/triangle/triangle_square.html The second applied math link is intended to give the visitors some idea of what sorting theory is about. http://tacnode.com/dev/sorting/beta/Sorting.html My first goal is to create really good applets for these two exhibits (which probably involves starting over). So please, if any of you know of some good programmers who might want to get involved in this enterprise could you put me in touch with them.? Thanks, David
