The uncertainty

Before we try to answer the question

whether the outcome of a collision
can be absolutely predetermined,

we should consider whether the state

of each of the colliding particles before
the impact can be exactly defined.

Πλαίσιο κειμένου: From the beginning of 20th century physics was in the midst of revolutionary developments which reordered our understanding of the Cosmos.

At first we found that light can be

simultaneously wave and particle.

Then came the relativity theory

and in the 20s we began to notice
that there is an inherent inaccuracy
regarding the location in space and
the momentum of an electron.

Πλαίσιο κειμένου: It was the principle of uncertainty, 
or indeterminacy

which states that both the position and the motion
of an electron are somewhat uncertain.

We had to develop new Mechanics,

the Quantum Mechanics.

It was a real shock to

our way of thinking.

A shock that we may not have

completely surpassed yet.

What was happening here?

In reality nothing special.

It was what we mentioned about

the blur in a photograph.

As long as we viewed the world

from afar we believed the
picture was quite clear.

As we increased the magnification and came
close at the atomic level, it turned out
that the image by its nature was somewhat "cloudy",
somewhat blurred, somewhat uncertain.

For the difficulty we might still have

in understanding the physical truth which this
principle describes, three facts are to blame:

·              the way in which it was initially
formulated using the term "random",

·              the fact that the calculations of Quantum 
Mechanics were based on probability and finally

·              the thoughts used to make
the principle easier to understand.

One of these said:

We will never be able to know exactly
what are the momentum and the position
of the electron because, while trying to
find it, we will interfere with the electron
and therefore change its state.

Consequently it is useless to ask
about the state of the electron.
We must accept it as random.

But is this really the problem?

Whether we know it or not?

Does not this consideration re-introduced

the age-old mistake of putting ourselves
in the centre of the universe?

Shouldn’t the electron be in a certain state
no matter whether we are concerned about it or not?
Is this not required by the principle of objectivity?
