Scientific stupidity

It's one thing for students have to wade through swamps of PC platitudes to get to the science in their science textbooks, quite another when those "facts" are wrong.

A study commissioned by the David and Lucile Packard Foundation in 2001 found 500 pages of scientific error in 12 middle-school textbooks used by 85 percent of the students in the country. One
misstates Newton's first law of motion. Another says humans can't hear elephants. Another confuses "gravity" with "gravitational acceleration." Another shows the equator running through the United States. Individual scientists draft segments of these books, but reviewing the final product is sometimes left to multicultural committees who have no expertise in science.
