Since it's correct in this case, then why it's not in the other !? - Since "The piano has become popular" is correct why we say for example: How a piano works instead of How the piano works ?? considering that: How pianos work. makes sense for me.

I am not sure I understand your question completely but I will try to answer it for you. "a piano" could refer to any piano. When you use "the piano" you are referring to a particular piano. Did that answer your question?

In my view all 3?ways are correct, however your sentences have other errors. How do pianos work? How does a piano work? (those 2 are most likely to be used) How does the piano work ? (least likely to be used) Scientests are trying to discover how minds work. Scientests are trying to discover how the mind works. How does a mind work ? ( least likely) How does the mind work? How do minds work? ( last 2 most likely)
