Can quantum mechanics be understood at all? Why is it accepted as a theory if one can not understand it? Because it is so tremendously successful and there has never been an experiment that would have disproved parts of it. It is the basis of modern technology, with the transistor and the digital technology being just one example. It only does not fit into our understanding world.

An example from the motor vehicle sector. You are certainly familiar with the many applications of a catalyst for the gasoline engine. Platinum 'favors' the oxidation and rhodium the reduction, but no chemist knows why. Are these catalytic materials perhaps very briefly involved in the reaction, or are they left where they are all the time?

At any rate, no surface layer may cover the surface, which would influence the chemical processes. At the end of a long period of time, the minimes which were necessary for production can be recovered quite accurately. Should one omit millions of catalysts, only because one does not understand its mode of action in detail? Of course not.

So we do not necessarily have to decide whether electrons have particle or wave characteristics. What is a wave and why is it not a particle? It is easy to explain with the example of the string of a musical instrument. It is tightly clamped between two points, Can also be the finger of the person playing the instrument. The shorter the clamping length, the higher the tone. It spreads in the space of the room.

If one now sits next door, hears that to a certain extent, also, even if the door between the rooms is closed. So it is not about air that flow through the room. Waves typically transmit energy without particle transport. However, the sound waves outlined here are dependent on matter, electromagnetic waves or light would not.

Another interesting approach: Can measure the length expansion of a railway rail by heating without having to encompass the entire rail network, one can also grasp the continuously expanding universe. And, of course, recalculate when it once had an atomic size, leave the Big Bang now aside.

This is sufficient to assume that certain laws of quantum mechanics are also applicable to our stars. So, as already mentioned, Niels Bohr lets electrons circle around the nucleus of an atomic nucleus like the earth around the sun or the moon around the earth. Advantage in the Electrons: By supplying energy, e.g. In the form of heat change their orbit.

However, the effect is only short-lived and with releasing energy the electrons return to their original path, recognizable by a tiny flash of light with clearly defined beams of typical colors. The frequency reveals the electron, since no other electron has the same energy level in the atomic shell. Do you now know what a quantum leap is?

Thus, by no means an electron passes continuously from one state to another, but changes its energy from now to equal, without any intervening. The problem: We do not know this from our world of experience. There are a 'tiny' and a 'giant' one, which are completely different from our intercourse.

If, however, we are thinking of the two areas, their magnitudes are so far from us that a possible creator probably did not expect that clever minds ever get an idea of them.
