The never-ending conundrums of classical physics
During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ positions and momenta could be arbitrarily specified; gravity acted instantaneously at a distance; the equality of gravitational and inertial mass was just a coincidence; and there was no speed limit. All these ideas and assumptions are now known to be in some way untenable. They're either inaccurate..
