'To measure' means, that a process is conducted, by which we refer to 
shape, size and behaviour of a system (in the macroscopic realm).

But nature does not support this kind of measurements, since natural 
systems are based on infinite variations of similar principles.

Example:  we grow a plant, say a tree.

With endless variations all trees look different, but somehow similar, 
even if they would stem from the same seed.

This is so because macroscopic shape is a function of a multitude of 
tiny entities, which have themselves no idea of macroscopic shape.

This is similar to clouds: clouds are composed from air and 
water-droplets. But the drops have no intention to create a specific 
shape of the cloud.

So all clouds look different.

This would not say, that drops are different and behave in different 
manners. Only size and shape could have variations, what makes 
macroscopic forms unpredictable.

So natural systems behave from inside to outside. And the larger forms 
are an overlay of smaller forms. And this goes up and down very far.

What we call 'macroscopic shape' is actually a certain level of a larger 
picture, which corresponds to the level we as humans beings have in 
respect to our own environment.

This may be our own preferred realm of measurements and where we would 
like to predict things. But nature has other plans, rather than to 
provide us with information about the future.
