Essay Abstract

In support of the assertion that reality is digital and not analog, this essay presents a discrete spacetime model that reproduces all of the phenomenology of the stamdard models of particle physics and cosmology and points to physics beyond the standard models.

Author Bio

Dick Dolan is a retired electrical engineer and the former editor of the Hewlett-Packard Journal.

Dear Richard,

there seems to be a habit for earlier essay submitters to welcome more recent contributors; I have just read the first page and a half of your essay and I am so pleased by some of the things you write, and by the style, that I want to be the first to say hi!

I'll come back with questions and comments later. Good luck!

Dear Sir,

Kindly forgive our asking some elementary questions. But these are essential for our understanding or rather due to lack of it. Describing what space-time is, you have given some postulates. How do you derive them? Can they be derived from fundamental principles? If not, and if we follow your route of examining whether a particular analog or digital model explains what we observe, does not the argument become circular reasoning – you prove something based on a postulate and validate the postulate citing the same theory? This is all the more important because you have defined points, quantum numbers, void, etc. in a way that is different from the conventional method. Without addressing the above issue raised by us, the rest of the essay becomes unintelligible. Kindly clarify.

Regards,

basudeba.

basudeba,

The "fundamental principles" of physics are not static. They evolve as we learn more about our universe. When we realize that we don't know something we wish to know, we need to expand those fundamental principles. We can't do this by basing new theories on the same old principles. We need creative new assumptions, axioms, or postulates. These needn't be based on anything. They are the bases. The theories based on them should make predictions, and if the predictions are correct, the new postulates need to be taken seriously. If they survive test after test over time, they become fundamental principles and we have expanded our knowledge of the universe. That's what I'm aiming for here. I don't think my reasoning is circular, and while my points are unconventional, the model based on them makes known-correct predictions as well as new, testable predictions.

I am very excited to have found this site. I was just given a fascinating read... "Theory of Concepts" by Richard P Dolan, Oct 25 1965. I would say Richard Dolan was a little ahead of the curve. My wife found this collection of writings going through some of my father in laws papers. I don't think it was ever published as I have it, but a really great read so far. Richard, Gordy was a great man, I miss him.

Richard

A fascinating essay with a fresh view. I was particularly taken with your discrete points and self reproduction. I do the same, with some paralells, but with an astounding result.

I hope you have chance to read and score it, but you'l need good conceptual skills. http://fqxi.org/community/forum/topic/803

Best of Luck.

Peter
