True, the page turned me off so much that I had the patience to look at only one "misconception": Why is the sky blue? What the site states is not that the textbooks are wrong but they could explain it in simpler terms. Well, then, misconception is too strong a word for that. And I think the simpler explanation had holes in it, too, e.g. "air is made up of blue particles, etc."
- acqq 16y agoI don't see the problem there. The author writes first clearly: "This one isn't purely a textbook error. Still, it involves misconceptions on the part of authors." He wants to point that it's not a misconception to explain that the sky is blue because of "wavelengths of light, Tyndall effect, and Rayleigh scattering" the misconception (in the approach to the presentation, not in the facts) is to explain only that single effect on that level and not mention that all the materials with which we are surrounded also have own colors because of the similar behaviors of atomic particles. That is a valid and important insight. And the misconception (again in the presentation, note again that he writes about school books) is not to mention that the air actually always has colors only that we don't register them because a lot of it is needed. I think it's good to point to all this.
