This fallacious result is not... a peculiarity of classical mechanics; it is given also by a very wide class of possible systems of mechanics. This being so, no minor modification of the classical mechanics can possibly put things right. Something far more drastic is needed; we are called upon to surrender either the [1] continuity or the [2] causality of classical mechanics, or else the possibility of [3] representing changes by motions in time and space.

About this quote

What does it mean?
Fixing classical mechanics requires abandoning continuity, causality, or representing changes by motion in space and time.
In plain terms
Classical mechanics needs big changes like giving up continuity or causality.
What can you take from it?
Major scientific problems require fundamental conceptual shifts.

Where it applies

  • discussing quantum theory
  • explaining physics limitations

Putting it to work

  • introducing quantum mechanics
  • teaching scientific revolutions

Questions to consider

  • What principles are we willing to give up?
  • How radical must a theory change be?

Another view
