The best example would indeed be the simplest. From there, you can
build up to more complex things. The wording will be vastly different
from what you are accustomed to because you have been using
mathematics during your entire tenure as a scientist. But, the numbers
should jive with equal precision.


The simplest possible example I can think of at the moment is
rectilinear motion. An object is moving in a straight line.

Using mathematics (say calculus for example) you might describe the
position of the object as (x,y,z) where x=0, y=0, and z=t. There are
lots of ways to write parametric equations, or transform things with
linear algebra, bla bla bla. All wonderful stuff and I dont question
it. Consider the interval t = [0, 10] and you have an object that
moves with constant motion for 10 seconds from (0,0,0) to (0,0,10).

But We will write this same parametrization a little differently.

First, the points along each axis, including time, do not exist with
certainty = 1. Lets make it easy and say that each point exists with
certainty 1/2 and just leave the "distribution of certainties"
uniform, I would call that a linear distribution as would most people
I suspect. We want the "expected time" to be 10, as in the example
above. The "expected distance" should also be 10.

So, along each axis, x,y,z, you have 10 units of length which exists
and you compose that with 10 units of nonexistent length. This gives a
total length of 20, but it is 1/2 nonexistent and so the expected
length is 10. You can view it 2 different ways, the nonexistent
portion is either discretely distributed, or could be continuously
distributed, either way it does not matter because they are equivalent
in terms of the end result. These are "conjectured lengths", and
clearly we are no longer doing mathematics.

You also have 20 units of "conjectured time", 10 exist and 10 do not,
giving expected time of 10.

So we want to model something which is "conjectured to be", we cannot
assume existence of our object either, it is conjectured as
well.....and we want that "conjectured object" to move the same way
the other one did in the original example. The origin (0,0,0) may or
may not exist, and the odds are 50:50, and so too each point may exist
with the odds being 50:50 all the way to (0,0,10).

There is a 50:50 chance that time will index forward at each moment,
and when it does we will find that (0,0,t) is is motion along the z
axis, we cannot know exactly where it is at any given moment because
1/2 the points in z = (0,20) do not exist. But t is also going from o
to 20, with 50:50 odds pointswise continuously and so it's really no
different than the standard mathematical parametrization.

Conjectured object has an "expected motion", moving from (0,0,0) to
(0,0,10).


That may need a little polishing and it sounds quite bizarre but it is
approximately what you would need to say to reason this way.

Why not? Where are they if they don't exist? Why do you think it makes any
difference?

[snip a whole lot of math about probabilities of existence etc]

And all the above is mathematics .. you were supposed to show something that
is NOT mathematics.

There are tools other than mathematics for producing quantitatively
predictive results?

What you've just done is still a form of mathematics.
