I'm certainly no physicist. I do however enjoy the subject. I find it inspiring to read about the history of the discipline.
The physicist turned philosopher of science Thomas Kuhn has long been my guide in making sense of the twists and turns of the natural sciences. He described the way in which one paradigm (for example Einsteinian physics) replaces another (Newtonian physics) in the march of progress. However, he argued that the new paradigm is always able to incorporate the functionality of the old.
This is why in an age when the errors of Newtonian physics are well known, and when relativity and quantum mechanics describe the (current) truth of our world, many engineers can still use Newton's concepts to build engines, bridges and buildings. Newtonianism is flawed as a truth, but for simpler practical applications still works.
