I have now looked at Heim Theory, but it does not look enough serious to me. Every theory that compute the masses of the elementary particles from nothing, must be wrong. Because in different possible universa the masses of the elementary particles are different. Besides, the Heim Theory could not explain the quarks. But from the Heim Theory article I followed a link to "Difference operator" ( http://en.wikipedia.org/wiki/Difference_operator ), and that article was much more interesting, because there you could find the extended Leibniz rule. And from that article I found a link to "Umbral calculus" ( http://en.wikipedia.org/wiki/Umbral_calculus ), that look like exactly what I am looking for. The Umbral calculus seems to be a good candidate for a tool for handling discrete space-time! -- Torgny Tholerus --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
