During its teenage and young adult yearsâ€”what is now referred to as its â€œclassicalâ€ periodâ€”physics made a lot of mistakes.
To put it plainly, classical physics is wrong. As such, there’s really only one thing to doâ€”physicists have since abandoned the old, mistaken ideas, right? It’s reminiscent of how doctors discarded the system of humors, chemists chucked out phlogiston, and astronomers turned away from astrology and geocentrism.
Not quite. Classical physics in fact survives as the foundation for most of engineering.
