As Anthony Atkielski (Mxsmanic) is a Pole living in France, I think we
can forgive him some lack of fluency in English, his third language.

I only speak two languages, and Atkielski's command of his third
language is much better than mine of my second.

It is not the 5 minute argument. It is not even the full half hour.
With Anthony Atkielski (Mxsmanic) it can go on for weeks, months or
even years.

He flits between Usenet newsgroups and disrupts one, then when the
mayhem is complete he moves on to another. It may take many months
before the cycle is complete and he starts all over again back at the
first one.

You're wasting your time trying to reason with him. Eventually he
will get bored and move on to the next group. In the fullness of
time, he will be back again, as sure as Spring follows Winter, Winter
follows Fall (Autumn), Fall follows Summer and Summer follows Spring.
And look! There he is again, and his craziness is just the same.

So string vibrations are digital? I think I read something like
that.

No it's not. In the real world, it's discrete, not continuous. You
only think it's continuous because the difference between discrete
levels are so small. An elementary charge is 1.602e-19 coulombs. An
electron volt is the amount of energy gained by that elementary charge
moved across an electric potential difference of one volt.

You can count electrons. You can't get a charge value that's between
discrete counts of electrons, i.e., digital. Sensitive sensors can
count photons. All photons of the same wavelength (i.e., color) will
have the same quantum of energy, which is between about 1.6eV and
3.2eV for visible light.

Even time is discrete, non-continuous. You just don't notice it
because a) the discrete jumps are tiny and b) you're living within the
discrete jumps and not an "outside observer", so your perception is
biased.

The real world is digital. The analog realm is conceptual because the
discrete levels between the digital values are smaller than we can
comprehend using only our organic senses.

Actually, I wouldn't have known that his first language wasn't English.

Mine too. And I obviously wouldn't ask him to let me try to redefine the
meanings of Polish words.

You're right, his command of his third language is impressive. He
earlier claimed to act as a guide for a few of the huge number of
American tourists who visit Paris, so that might be one way he has
improved his fluency. On the other hand, he spends a lot of his time
on English language newsgroups and has done for years.

Oops, sorry. My comments still apply, just to a different person.

A beautifully crafted phrase. Thank you.

Or a Geiger counter. It's a common misconception of large animals like
ourselves that we live in an analog world. It just seems that way of
you're a large animal. Photons aren't analog.
