A point that Kuhn makes in his book is that yes, Newtonian mechanics is still very useful, but relativity demonstrated that it is <i>wrong</i>. That is, Newtonian mechanics implies that we live in a particular kind of universe. That implication is false. No matter how useful Newtonian mechanics is, no matter how close it is to being correct in the situation we&#x27;re familiar with, it is wrong, and the implications of the kind of universe we live in is not correct. <i>That</i> is huge, as it required that the people who think about this for a living (physicists) had to change <i>how they thought</i> completely.<p>I recommend reading the book, as he goes into this kind of objection. One of his main points about the paradigm shift is that afterwards, the way scientists think about the problems has changed, and as a result, the kind of questions they ask - or even can ask - has changed.
