I must have been lucky to have some very good teachers. The information was usually presented as though it was only the best that was currently known, and open to future alteration by new discoveries. I had many teachers who would spend class time teaching us things that were not in the textbooks.
I didn't encounter the dogmatic intransigence until I got to university. There things were a political game, where the highest awards went to the most dutiful slaves. Then the most obedient went on to their research grants and reinforcement of the established order. People who are disruptive don't get research grants. That is not to say it is necessarily a monolithic conspiracy, as much as it is a CYA operation, defending the paycheck of the status quo. A Richard Feynman today, would never be given tenure.
This is a man of science, from before the structures of regulatory capture had yet fully been constructed.

The picking apart of education is just despicable. Alas why do we want a society of free thinking individuals, no that won't do. We need good little worker bees. This is one of the reasons I hold those working on the electric/plasma universe theory in a higher regard at least they are going against the status quo. As far back as Newton's "laws" and even questioning them. To the point that physics itself would be turned upside down and have to be completely rethought. Wallace Thornhill touches on this briefly in the video I posted.
Feynman sure did have charisma for a physicist. To bad he had to work on the a-bomb...
I think there are many science minded people who are enthralled by the incredible possibilities that the practice of the scientific method represents. The manipulating interests of money and power will always seek to control, or destroy what they can not control. Paul Feyerabend has his place, but experimental data is king.
The electric universe is intriguing to watch develop. I became aware of bits of it alongside Tom Bearden in the 1990's.
