Re: Scaled or Granular Dates

>> January 2004 Scientific American? It is mind blowing. It might
also be wrong. The preamble reads 'We perceive space and time to be continuous, but if the amazing theory of loop quantum gravity is correct, they actually come in discrete pieces'. ... but maybe the sweeping statement about continuity of time is overstated. <<

That is on the stack for the month. I am swamped right now; one of the many problems with being a grown up is that you have to provide Christmas instead of enjoy it. Actually, Wolfram is into a fuly discrete model of the universe-as-finite-automata that is interesting.

and Temporal Reasoning" by C Bettini, S Jajodia, S X Wang, published by Springer, 2000, ISBN 3-540-66997-3 (in Engish, despite the ISBN prefix suggesting German). I've not read it all yet - on the to do list - but it might be of some relevance, too. <<

Sounds good; I'll take a look. Do you have the Morgan-Kaufmann book by Rick Snodgrass? Lots of code, but you can go back to his work at University of Arizona for the theoretical stuff. Received on Thu Jan 08 2004 - 17:28:57 CST
