I am an intern in germany as a german. The focus of the company isn't directly the same as my area of study (I study computer science, the company mainly designs, solders and programs hardware). They surely know things about computer science, but mostly from their hardware-making perspective.
They needed someone with my skills to do a project which is too far away from their skills and knowledge. I should research about connecting two Components A and B and how someday A can be connected to a future existing component X.
My Boss is also a Professor in electronics and very self-confident.
I have to explain to him how he can connect A and X on his own. I tried to document as easily as possible how I connected A with B and how A can possibly be connected to X someday.
Every time he doesn't know what I mean, he gives me the feeling that I don't know what I am talking about. He asks me for details which I can't explain because they're none of my business. After I tell him that it isn't neccessary to know, he gives me the feeling that he doesn't trust the things I told him before. There are even details I can't explain to him because he doesn't have the knowledge and I can't teach him.
While I was very introverted in the past, things are much better now. But I have problems in expressing myself when I have to talk and discuss with persons of authority.
After my internship, I have to study for another year before writing my diploma. While it is really hard to communicate with people which have no detailed knowledge in my area I try to get another job after my studies. But in order to get a good employer's reference I want a "happy end".
How can I tell my boss that (at least) I can't help him due to his lack of knowledge?
