My name is Michael Thudén and I'm an inventor (not a real mathematican or biologist) but I think I have stumbled across something that might be of interest. It's a simple symmetrical geometrical binary model that can do arithmetic, (the division and multiplication are clumsy, but I wanted to show that it works), represent Boolean functions (corresponding to subsets in binary-trees), and express some sort of memory. I think you can skip these parts about Boolean functions, arithmetic and memory (or read it later) if you want to save some time. The system also has the ability to be used as a binary coordinate system, meaning that arithmetic, Boolean function and memory can be used in a plane or space context regarding different positions. The system can be expanded into a three dimensional binary-sphere that have some remarkable symmetrical properties (beside those described above) corresponding to biological cells. For example: the binary-sphere can only be divided symmetrically into two binary-spheres starting from an equatorial-plane perpendicular to the two poles. A biological cell alsodivides starting from the equatorial plane perpendicular to its poles (see metaphase plate in mitosis). The two "new" binary-spheres will consist of one half from the "old" binary-sphere and a new constructed half, exactly as in a biological cell where one half of the "new" cell is from the "old" cell and the second half is "new". Further more: the binary-sphere can use the "binary-coordinate" system in assembling divided binary-spheres to each other (can it be used in DLA simulations?). It's easy to make a "genetic" binary code that generates radial, spherical and bilateral symmetries (the binary sphere is by itself bilateral). To make bilateral symmetries it's even possible to use the same code for the left and right side (there's no need to have a separate code for each side). The interior of the binary-sphere also have a compartments that can be binary described (and perhaps be used as a simulated cytoskeleton?). So if you think this sounds interesting go to my site http://members01.chello.se/rocker/telia/bin/eindex.htm and check it out. This is a pure mathematical approach and though it's been a while since I studied math at university the math is stable according to some "real" mathematicians that's been checking it out. I hope that you find the reading interesting, in spite of my poor English. I'm grateful for all constructive criticism, which also include the linguistic part. Michael Thudén .
