It sounds like there is enough material among us all to perhaps pull it together in a single book. If anyone would like to work on pulling something like that together...
BTW, Is the four-color theorem still one that has only been proven "by computer" or is there now an elegant mathematical proof too? --dawn On 5/11/07, Anthony W. Youngman <[EMAIL PROTECTED]> wrote:

I ought to rewrite my stuff about MV. What I'll try and do is write a "Why MV" article. I've found a nice little Einstein quote - "As far as the laws of mathematics refer to reality, they are not certain; and as far as they are certain, they do not refer to reality." And there's always Knuth - "Beware of bugs, I have only proved this program correct, not tested it". You know my complaint about Relational is maths not science ... :-) I need to word that in simple words that a novice can understand, and then we might break the relational death-grip :-) I've got a new analogy to replace Newton :-) You know that map problem? How many colours it takes to guarantee no two adjacent regions share a colour? Well, it's easy to prove that seven colours are both necessary and sufficient ... Hang on!!! EASY? And SEVEN? Well, it is. Provided you choose a convenient reality to do it in. Just don't choose a two-dimensional reality to do it in. Bit like database analysis, really. It's easy, if you don't choose a two-dimensional reality to do it in :-) Cheers, Wol -- Anthony W. Youngman <[EMAIL PROTECTED]> 'Yings, yow graley yin!
