hi safp7

welcome to the forum.Why can't you post links?

Hi safp7;

I have heard of that, but know little about it.

Links can not be posted any longer inside posts until you are a member.

Here is the link:

Welcome to the forum.

Hi safp7;

When I said I did not know much about it that was incorrect. I just did not recognize that video. I have even had that discussion on this forum. I think basically his approach of discretizing math is correct. If you read the work of Doron Zeilberger you will see that has been vigorously suggested already. Unfortunately it is has also been vigorously rejected. I do not want say how long I have been fighting with math types to get them to understand or even try computational math.

The ramifications of discretization are huge. Essentially most of continuous math and the ancient greek concept of proof is to be discarded, in favor of a mathematics that more easily lends itself to computation. They will not change in your lifetime.

I also recommend David Deutsch's book because it has stunning ideas. We call what we do, "Experimental Mathematics."

Hi safp7;

My memory for these things is not good.

This is Doron's opinions, they are good reading and inside them are some of his viewpoints. He also makes rather popular videos on youtube. His page is a good source of his heretical views.

His best mathematical work is A = B.

I think David's book is called the :The Fabric of Reality."

About the last, I can never find anything I blather about.

Hi;

If you were able to understand him with his thick accent, then you are ahead of me.

I'm talking about rigorous definitions, not just discussions regarding discretization of continuous mathematics.
Are you familiar with other discrete or semi-discrete versions of concepts in Calculus?

The only part of it that I can understand is what I learned through numerical analysis. Discretizing happens all the time there! DE's are approximated by very small straight lines, curves are fit by using splines, areas are done by stuffing trapezoids inside them, sums replace integrals and differences replace derivatives.

I am afraid that there is no collected body of knowledge on this. You will have to search till your keyboard melts. Just make sure you write down where you find things else you will be in the same spot as me.
