But the whole act of building an engine rests on the work of engineers and physicists who developed the metallurgy and designed the components and production machinery to make the components.
I doubt there is a single physicist designing model engines.
It's obvious you missed my point in the above excerpted quote. You should reread it for better comprehension. Hint: Didn't say physicists were designing model engines.

I know what you were trying to say, and you are wrong, physicists don't design model engines, nor the tools, nor the metallurgy. Not even a lot of engineers are doing that nowadays.
