The wave nature
of matter
however We
arrive at the same results
(equations,
calculations)
if we apply wave mechanics
which instead of using the concept of
"random",
accepts that the electron
has a wave nature.
Matter is,
like light,
simultaneously particle and wave.
Observing an object,
say a glass,
we get the firm impression
that
it has absolutely definite limits.
Somewhere the glass
ends
and the air begins.
The border
is absolutely clear.
If we go very close,
using a high magnification,
we expect maybe to find that the surface
is not as smooth as it appears to us, that
some irregularities are present, which
previously were not detected.
In no case, however,
would we expect
that the boundary that separates the
glass from the air to be unclear.
This, however,
is our mistake.
That the boundary where a material body ends is perfectly sharp,
is something we have assumed but haven’t proved.
Well, now it turns
out
that this assumption
was wrong.
In reality the situation
is different.
The boundaries are
unclear,
their kinetic condition
cannot be fully defined.
If it so, and (unfortunately
or thank God?) it is so,
and the basic building blocks of the
Cosmos are by their nature "fuzzy",
then it is clear that the result of each
collision cannot be exactly
predetermined.
which makes
it impossible to draw a line, as we did it in Chapter 6,
back from the current state of
the Cosmos to its beginning.
With each
collision the degree
of uncertainty about
the outcome increases
because to the uncertainty of the first particle is added
the uncertainty
of those it collides with.
The longer
time passes,
so many more collisions take place,
and so much greater is the freedom of the system.
