Der Weg

At the beginning of this consideration a question should be asked that refers to the critical comments of the introduction. It is known that the emission of an electromagnetic wave of a Hertz’ oscillator can be described very well and illustratively. However, this idea will fail immediately if you try to develop a clear descriptive model of the emission of a light quantum from an atom. This is one of the peculiarities of quantum theory. On the other hand we cannot see any significant difference if we compare the products of the two emission mechanisms (i.e., the electromagnetic waves) and therefore have every right to ask: Why in one of two methods to create a physical object the mechanism should be clear while not in the other one? This question is only a means to approach the field of quantum theory from another perspective (rather than the common one). We will therefore follow such a path allowing us to develop a causal image of nature and begin with the equations that describe the emission mechanism of an atom.
It is to be assumed that the handling of our subject does not imply the desire to explain each character or symbol precisely since such explanations generally disturb one’s train of thoughts. Instead, we will only try to use those characters which can be found in any textbook of physics, and, if necessary, introduce clearly understood characters.
Now we will have a look at the following equations:
