Correction to what's on the screen at 9 mins 35 seconds: In the lower equation, the h-bar is missing. Sorry about that!

Correction to what I say at 3 mins 39: it should have been phosphorescent materials, not fluorescent. (Same basic principle, but the lifetime of the states is longer for the former than for the latter.)

What is Heisenberg's Uncertainty Principle, how does it work, and what does it mean? Is it really a quantum principle or is not just fourier transforms? I'll sort it out for you.
