What is a physical theory? — The answer is crucial for anyone who wants to understand quantum mechanics.
This video is the first in a series about quantum mechanics.
In this episode, we discuss the general framework of a physical theory. In particular, we look at the mutual relationships of the physical and mathematical parts of such a theory and we begin to clearly separate the concepts of known and unknown quantities.
Consistency of observations is emphasized as the measure of reality of physical concepts as opposed to the mathematical definitions and rigor applied in the mathematical part of the theory.
I create videos about science (physics) and coding in English and German.
