Before I headed out to Dallas I bought a new pair of sunglasses, since I managed to wreck my last pair in Lanzarote. They were a fairly cheap pair, since they always break or get lost sooner or later. When I put them on during the week, I realised there was something odd about them. And today I worked out what it is – they have polaroid lenses, so they darken by blocking light that is polarised in a different direction to the glasses.
Which means that you can see polarised lighting. This is usually LCD displays (my blackberry looked like the display was broken), and offices with clever windows. But most surprisingly, the sky isn’t uniformly polarised, with the depth of blue changing as you turn round in a circle. I don’t know why this is. I guess some googling will be required.
But anyway, as a result, I feel like I’ve got some kind of superpower – the ability to see polarised light. It’s a very minor superpower, I admit. I don’t expect to get my own plot-line in Heroes or series of comics or anything. But it is kind of interesting. Well, it is to me anyway.
