Sure, technicians and engineers need good understanding of the 
principles they use.

But engineers do not care that much about what physicists actually do or 
worry about.

Engineers worry about their machines and simply do not care, whether or 
not physics would allow them to work.

If it works, than it's ok. If it doesn't work, engineers try some 
modifications or something else.

But engineers do not care much about WHY the machines actually work. 
(They leave that part to physicsts.)

This very similar in medicine:

there exist one kind of doctors, who are happy, if the patient recovers.

the other type wants to know, how this happened and does not regard as a 
cure, if the underlying principles are unknown.

No, I'm actually an engineer from my education.

Physics is kind of hobby for me.

I had written a few things and the very first was my 'book':

https://docs.google.com/presentation/d/1Ur3_giuk2l439fxUa8QHX4wTDxBEaM6lOlgVUa0cFU4/edit?usp=sharing

I spent a lot of time on that, but it's rather old now and I'm not that 
happy with it's content today.

But at least I have something to present.
