# It may quack like a duck, but it's only a duck when it hits the plate

```Hi Telmo Menezes

The Schrodinger wave equation (SWE) uses a "quantum wave function" psi(r,t),
which is the
mathematical probability that a quantum particle will be at certain location r
at time t. ```
```
Solution of the Schrodinger equation for the two slit experiment will
give you an interference pattern at the photographic plate even though
the quantum wave function psi is just a mathematical expression.

Psi only converts to a particle when psi arrives at the photographic plate.

So psi is not physical, it is a mathematical solution to the particular SWE.
The only physical part of the experiment is at the end when the wave hits the
photographic
plate.

Hi Roger,

Sure, neither do I.
But if you preform the double slit experience you will see physical wave-like
patters of interference. If it quacks like a duck...
I'm not a materialist and I have no problem with the idea of the physical world
being a dream. But I also believe that all experiences are equally real,
including dreams. Including the literal dreams we have when we sleep. So I
believe in the physical world without being a materialist.

I don't pretend to be a physicist, but I do know that
quantum waves are probability functions. ?here are
the radius and time t in the Schroedinger equation,
so there must be some correpondence to the physical world,
but nothing physical is waving.

So suppose we have a physical box. ?he probability
waves have to conform to the dimensions of the box, but
they are ghost-like waves of probability.

Hi Roger,

How can you have a wave without some notion of spatial/temporal dimensions?

Hi everything-list,

I don't believe that Descartes would accept the MWI.
Here's why:

I think that the ManyWorldsInterpretation of QM is incorrect,
due to the mistaken notion (IMHO) that quantum waves
are physical waves, so that everything is physical and materialistic.

This seems to deny "quantum weirdness" observed
in the two-slit experiment. Seemingly if both the wave
and the photon are physical, there should be nothing weird
happening.

My own view is that the weirdness arises because the
waves and the photons are residents of two completely
different but interpenetrating worlds, where:

1) the photon is a resident of the physical world,
where by physical I mean (along with Descartes)
"extended in space",

2) the quantum wave in nonphysical, being a resident of
the nonphysical world (the world of mind), which has no
extension in space.

Under these conditions, there is no need
to create an additional physical world, since each
can exist as aspects of the the same world,
one moving in spactime and being physical, the other, like
mind, moving simulataneously in the nonphysical world
beyond spacetime.
