Big-time professors write textbooks (mainly) to learn the subject. -TLWDonald Simanek wrote [in part]remember.
There's an even more fundamental pedogagical principle we should

out.a level well beyond the level of the course. If in doubt, leave it
one's ownOne of the marks of an educated person is to know the limits of

education,knowing" is "knowing things that aren't so".Now if we could just get that information to the professors of

This is interesting in two aspects: 1) Our students teachers with a
concentration in physics are required to take 30-32 semester hours of
physics and 6 semester hours of methods/materials in science
education.
How many more hours of physics do they need to know it "fully"? ; and
2) if
teachers waited to teach until they understood everything fully, would
anyone be teaching?
