"... And that's why the first thing my A Level Physics tutor told me to forget everything I had learnt at GCSE because it was either a lie or an over simplification.
I was then told exactly the same thing at degree level, seems a perverse way to teach to simplify things to the point they are factually incorrect and then have to "correct" that knowledge at a later date. ..."
One of our degree lecturers said it thus: "We teach you by diminishing deceptions" .
I thought it was fair enough, *if made explicit*, for e.g. starting with Newton, which is practicable enough for some purposes, before moving on to Einstein.
With you on pointless, ambiguous or not-even-right-or-wrong questions ;-)
