Was doing polarisation with my class and unusualy for me I did a couple of real demos rather than simulated ones. First I did a demo passing a laser through some sugar solution placed between crosses polaroids. Not exremely convincing, would have been better to put the solution into a glass cube rather than a beaker. The other demo was looking at a piece of perspex through a polaroid filter, the perspex was held in front of my computer screen to provide polarised light. Students liked this one as you can see. They liked the hologram of a dog even more, pity this isn't on the syllabus.

Yeah images in comments would be nice I'll pass this on to the web designer. By the way the post now has an image that was supposed to be there but for some reason disappeared. I tried to take a photo of what they were looking out but it didn't come out well.

I want to post an image response! This is a post that needs an illustration, and if I could post my reply as a photo that would be nice. Is it possible to add that function within this framework and without typing html code? Or are you trying to avoid extensive maintenance work removing inappropriate material? (As you have to pay and register I would not think that would be a major problem.)
