In the past, I believe medical professionals said there was no link between excessive reading (or other close-up work) and myopia.
Now I think they like to bandy about a study showing that law students usually have worse eyesight when they graduate than when they enter, presumably due to all the reading needed to complete a law degree.

You may have missed Carl Sagan and other scientists making flat assertions that it would happen, contrary to this thread’s erroneous argument that “scientists almost never speak in absolutes”. Whether nuclear winter actually occurred (or failed to occur) stands as immaterial.

Yeah, like it’s gonna be accepted back after putting on airs and going to the Planet parties for 60 years.
As far as the OP. There is the How do airplanes fly bit. When you are in first grade they tell ya that it obvously flys just like your hand does when stuck out of a care window. Then by 5th grade they say that is wrong, and it’s all airfoil and Bernoulli effect to cause lift. Then by college it’s back to deflected air, just like a hand out of a car window.
And don’t forget glass. Originally a solid, then a quirky liguid, now back to a liquidy-solid.
