The ability to predict

Our way of describing the natural law,

e.g. with an equation that we write on a piece of paper,
reflects only roughly that which is prescribed by the Natural Law.

The accuracy of the description of
what is actually happening is limited.

This approximate description though is

extremely useful as it provides us
with the ability to make a prediction.

Πλαίσιο κειμένου: It may be that the accuracy of our prediction is limited but nevertheless 
we can still achieve our purpose.

That is the way all applications are made:

We plan, say, the construction of an aircraft and we predict:
This machine will be able to take off with a load of 60 tons
and reach airspeed of 700 km/h.

After the construction, during the test flight, we note usually
that we have erred only slightly. The machine carries 59.7 tons
and it reaches 705 km/h.

Our ability to forecast varies from case to case.

We can predict the motion of a planet in
the solar system with great accuracy;
the movement of a leaf falling from a tree
with less.

Πλαίσιο κειμένου: We know very well the reason why the accuracy of our prediction is limited.
It’s due to the limitations of our knowledge.

The more we study the phenomena,
the greater is the accuracy of our

We correct our expression of the law,

for example by introducing an additional
factor into our equation, and we measure
more accurately the initial conditions which
sometimes affect the result considerably.

Sometimes we may need to change

the whole formulation or even
our perception of the phenomenon

which does not mean that we should give
special significance to this event.
