There have been a lot of high school physics questions here lately.
Are the teachers & textbooks really dumb enough to ask homework
questions invoking principles not yet even introduced to the students?
Do students really think that they can buy understanding at a few
dollars a pop? Do HS students even have enough money to buy all the
answers this semester?
