Behaving as Both a Wave and a Particle

"One of the most mysterious things about light, is that when you really get down to it -- and this is not just true of light, this is actually true of almost anything once you get on to a small enough, quantum mechanical level -- that light behaves as both a wave and a particle."

~ Sal Khan, from the Khan Academy tutorial "An Introduction to Light"

Using Technology to Humanize the Classroom

“By removing the one size fits all lecture from the classroom and letting students have a self-paced lecture at home, and then when you go to the classroom, letting them do work, having the teacher walk around, having the peers actually be able to interact with each other, these teachers have used technology to humanize the classroom.”
