If I may interject an off-topic comment, I tend to agree that teachers treat some topics as if they were written in stone by God. this is nothing new.

My fourth grade teacher (1954) had lost her son in WWII and would seldom let a week go by without assuring us that the only good Jap was a dead Jap. This woman spent her summers traveling the world.

One of my son's teachers assured him that snakes do not have bones.

I could mention a couple of other stories, but my point is I believe people when they say teachers frequently fail to mention that scientific knowledge is subject to update and correction.

Snakes gots bones? My favorite, and it's incredibly common, is that if the earth stopped spinning, we'd all fly off. because it's the centrifugal force acting on the air column over our head that holds us down. That's what we get for letting people with ed. degrees teach.
