"There is no gravity in outer space. Gravity ends at the top of Earth's atmosphere. That's why astronauts in the ISS are weightless." Simple and concise. Easily understood by little kids. Textbooks in the 1950s actually taught this "fact." What could be the problem? It's not "simplified," instead IT'S WRONG... ...and it creates a massive physics-misconception, where if a student actually believed it, later they'd have enormous trouble in physics classes. (Also, if they later became a teacher, then they'd give all their students the same destructive misconception. If later they became a textbook author for K6 grades, millions of students would become infected! Heh, education is a viral effect: a meme-spreading process, and "mental diseases" like the above are common.) |
