Acquisition of Information is Achieved by the Measurement Process in Classical and Quantum Physics

TL;DR

This paper explores the nature of measurement in classical and quantum physics through an information science perspective, revealing measurement relativity as a fundamental property consistent with quantum mechanics and relativity theory.

Contribution

It introduces a formal framework for understanding measurement as an acquisition of information, highlighting measurement relativity as a core principle in physics.

Findings

Measurement is fundamentally about acquiring information.

Relativity is a basic property of measurement.

Measurement relativity aligns with quantum and Einstein's theories.

Abstract

No consensus seems to exist as to what constitutes a measurement which is still considered somewhat mysterious in many respects in quantum mechanics. At successive stages mathematical theory of measure, metrology and measurement theory tried to systematize this field but significant questions remain open about the nature of measurement, about the characterization of the observer, about the reliability of measurement processes etc. The present paper attempts to talk about these questions through the information science. We start from the idea, rather common and intuitive, that the measurement process basically acquires information. Next we expand this idea through four formal definitions and infer some corollaries regarding the measurement process from those definitions. Relativity emerges as the basic property of measurement from the present logical framework and this rather surprising result collides with the feeling of physicists who take measurement as a myth. In the closing this paper shows how the measurement relativity wholly consists with some effects calculated in QM and in Einstein's theory.
