Son in third grade has a test this Friday in physics, on material that I studied in high school. He needs to know the difference between potential and kinetic energy, what kinds of media sound will propagate through, and how to change the pitch and volume of a sound wave. Good things.
I hope he's fluent in JavaScript and Klingon by age 12. And, I introduced him to weird Al on desktop_uri=%2Fwatch%3Fv%3DN9qYF9DZPdw
