There are many alarm bells ringing in my head while looking at his
article, however I haven't seen anyone demonstrating that his axioms are
flawed.
<shrug> To be honest I didn't get past the first few seconds of the thing.
My BS meter pegged and I figured I'd better bail out before some of that
leaked in my brain. Laplace and Fourier are already trying to leave. Then
you have these z transforms instead of s's. What's the world coming to?
It's a zoo I tell ya.

It might be a useless system, but (pure) mathematics doesn't care about
that. Considering all the press this has gotten, if it's an obviously
stupid idea (the system having a big blinking showstopper), we should know
that very soon.
Dividing by zero in computers is bad.
Dividing by zero in mathematics or engineering analysis is defined
(from a behavior standpoint anyway).
It's not defined for the real numbers nor the complex numbers. However,
you can make it defined by doing "tricks" like extending the complex plane
by adding a special number oo (infinity).
The problem of computers not being able to handle that kind of
analysis without "fudging" is a well known shortcoming of computers. Some
of those problems can't be handled well even with a fudge so are
nailed as "undefined". They're only undefined in the digital world!
Is there any kind of mathematical computation/analysis you can do that a
computer never will be able to do?
Cheers,
Jarle
