I was once thrown out of class and blackballed from
NHS for insisting
that my high-school (PhD yet) chemistry teacher was wrong.
Something about me not having the proper respect for authority...
One of my hobbies at school was disrupting lessons by asking nasty
qeustions _on the subject of the lesson_. Point being had they kicked me
out for doing that, my parents would have exploded with the school
Seriously.
I once walked out a physics lesson and said I would only return when the
teacher had actually learnt some basic physics. That did not go down
well. But, you know, I am still waiting for a defintion of a (scientific)
measurement that does not involve comparison to a standard.
