Y'see, this here is how I view one of the main differences between ignorance and stupidity.
I don't blame a random person for being ignorant of the difference between incandescent and florescent lighting. No reason for most people to know or care. And if for some reason they want or need to know, they can find out.
But for someone like a physics teacher, who SHOULD know, but not only DOESN'T know, but also INCORRECTLY BELIEVES he does knows...
I hope you double checked everything else that teacher "taught" you. How can you trust him?
p.s. Light up a CFL bulb and a halogen bulb for a few minutes, and unscrew the CFL bare handed. Tell your teacher that if he's sure they are the same, he should do the same with the halogen....
