I hear the term "paradigm shift" used in news articles, commentary, etc.
It appears to have been first defined by Thomas Khun in his book "The Structure of Scientific Revolutions".
Sometimes it is used in relation to the "zeitgeist", which appears to refer to the general idea/movement/ideology of the present day (sounds similar to Hegel's "geist").
So my question is: what is the meaning of this term "paradigm shift", and does it refer to a legitimate concept?
"Paradigm shift" is actually two concepts.
"Paradigm" means "a philosophical and theoretical framework of a scientific school or discipline within which theories, laws, and generalizations and the experiments performed in support of them are formulated; broadly : a philosophical or theoretical framework of any kind"
I'd say that a paradigm is a set of basic assumptions made and required by a set of theories.
A paradigm shift, or intellectual/scientific revolution, is when those basic ideas get challenged and rejected, and a new set of basic ideas take their place, requiring new theories to be created for understanding the same phenomena.
The Copernican revolution was a paradigm shift, a shift from one basic assumption to another.
That said, I prefer the term "revolution" to "paradigm shift". It's less of a buzz-phrase.
