Agent Smith, This looks so neat! I'm impressed with this new rocket engine, but I'm almost as likely to understand how it works as I am to be able to understand string theory. It all goes to show that there are more things in the universe than are dreamed of in my philosophy. - meanwhile I'm stuck trying to figure out how to get skewing to work right in more than 1 dimension, looking at the code for an old set of fractal fractal programs(the hardest part was getting the "FAT" files onto the "NTFS" computer ) and O.T.: Dr. Kaku or his webmaster or (?) sent me the update for his site at www.mkaku.org and I was looking at the formulas Dr. K. uses to explain his 'string' theory. I'm not able to completely understand the calculus he uses as simple as it seems, but I have derived a new way of saying 'the black hole of emotional need'. I can now use the phrase 'the p-brane of emotive necessity'. (Of course I wouldn't use a term like that but it's nice to know I can.) It's an interesting site if you're into that sort of thing. I'll have to try something along the line of your lattice. Thanks for sharing! - TJ
