PHILOSOPHICAL PROBLEMS OF QUANTIC PHYSICS
IN MEASURING PROCESSES AND INSTRUMENTATIONS

 

The different fields in which the measurement techniques can be included partial also in the sphere of the automation systems. However, at the large majority of the applications the man is that which receipt the information which results after the measurement. However much they endeavoured, the researchers did not succeed in the achievement of the so complex automatic devices so that one can say that its own thinking, sentiments or judgement. What means in fact to think? What means the mind? If the mind exists, how much it is connected with its material support which it is associated with? Should exist thinking independent of such structures? If we analyse the situations we observe that the notion of artificial inteligence is improper assigned to the electronic systems so named (systems which work after a perfectible program but which did not understand what its make). We did not know if it submit to the phisycs’ laws and after all what are the phisycs’ laws something else than an emanation of the human mind based of course on logics and mathematics (but also on experiment)? Certainly how long will not exist exact answers at these questions, as well in the metrology field will be problems which will be unsolvable or partial solvable.
Although the metrology is constitiuted as an independent science, with explicit laws for the specialists which practise it, the scientists and the philosophers whis interest in this field are very preoccupied by the imposible things. There are opinions which affirm that the science is possible in general because there are imposible things. The measurement action has mostly the equilibrium (compatibility) on the base. There are equilibriums described mathematically by special solutions of the equations, whose stability did not be decided. For this decision imposibility has an impact over some problems of real interest on metrology, the equilibriums must imply the playing of a very great number of interactions.
What special we must to know about nature to appreciate correct an achieved metrological action and how we must achieve it to find the information we interest it with satisfactory accuracy? If our conscious perceptions are not something else that the result of some algorithms succeeding, as more adepts of artificial inteligence believe, then should not of great importance which are the nature laws. The experimentalist’s mind influents the experiment or the measurement result? The quantic physics affirms that the measurement modify the measured medium and influents it with an intensity probabilistic computed, therefore the measurement result is different by what should be if the measurement should not be achieved. Moreover, the incertitude principle from quantics forbids us to determine with accuracy both the position and the impulse, therefore, as much as precise we should be on measurements only a half of information can be obtained in this case. It still has sence to go in search of new and more accurate devices and methods?The result of one measurement is the found value or the value created by our mind?
