Extreme Education: Polarising Your Face

Everyone's favorite mad scientist, Professor Terror gives us an extreme lesson in polarising light waves.

He got black nails xD

hello, can anyone tell me the formula for intensity for multiple polarising filters (not just two...)

Enjoyed your polarization* demonstration. The real fun starts when you crumple cellophane and put it between the crossed polarizers. That is what led us to our art and what Dr. Land told us is the way he wooed his wife. Join us in the celebration of polarized light art at austine [dot] c o m. Cheers... *That's how we spell it on this side of the pond.

i stumbled upon your video. very interesting but what i was most impressed by was the soundclip from "release the dogs" by boysetsfire in your intro... great choice!

thanks for the vid, im just studying polarisation now and this explained it well :)

the sensations sells every ting...this dark angel simulacro teach very well, maybe the childs put more atention to their clasees if the teacher looks like this...good work

It goes something like this: Alice randomly chooses a photon in the \, |, / or - plane to send, Bob reads it (+)- or (x)-wise, they then compare publicly which of + and x was used on each end. If both had used x and someone in the middle had measured with +, Bob would see that half the time the signal was in error and would suggest switching channels.

Consider that the blue receptors in our eyes are polarizing (individually, though not in aggregate except a little around the fovea) which means light's as bright to them as us in this respect. I think the two main differences to ants would be the brightness of the sky and the fact that anything with compound eyes is horribly myopic.

this voice effect is annoying... :/

Did you know that the principle by which a polaroid lens at 45 degrees to the current polarisation can "re-polarise" light is the principle on which quantum cryptography is based?
