    Junior @ Highschool:

    Just looking at what the bleep do we know on you tbe and it was talking about 2dimensions, no up or down but since everything particle has space, how can 2 dimensions ever exist?

    Also, why are clouds and snow and sometimes fog white while rain is not? Is it do to crystal allignment?

    Thanks, curiosity is human nature :wink:

    Everything we can observe is 3-dimensional but when you try to describe the position or motion of objects, it is sometimes easier mathematically to just use one or two dimensions. There is no point in writing more equations than you need for the particular problem at hand. It's really no more complicated than that.

    As far as the second question is concerned, no it's not crystals. The fog is a liquid, like the rain, so it doesn't have any crystals. Snow is ice crystals, but ice can also be transparent. I think it is the fact that snow and fog are very small particles.

    For the material to be transparent you have to be able to see an image through the material. That means a light beam has to go pretty much in a straight line through it. With snow or fog, it gets reflected or refracted too many times on its way through, so it breaks up the image. The same thing happens to a piece of glass if you crush it up. Each individual shard of glass is still transparent but it gets harder to see through the more pieces it's broken into.
