Brownian Motion at la Cite

Here's a model of an experiment that we can do to verify the scientific belief that matter is made of atoms that fly around really fast (they also bounce off each other so much that they never really go anywhere). This kind of atomic motion is called Brownian Motion. The big ring plays the role of something really small, but that is big enough that we can see it using a microscope (like a biological cell). The smaller metal balls represent atoms, which in reality we can't really see because they are too small. Instead of just sitting there, the cell is observed to jiggle around randomly, a result of the collisions it has with the smaller, faster atoms. This is an exhibit at la Cite, Paris.

pretty cool, bud.

I think that's not complete move because the green ring is not continuous move. sometime the green ring is bumped by elastic. This model is not complete.

cool!

Awesome video.

i have to do a project on the guy that made this and i didnt no wat it was but this helped

looks like a mix between air hockey, crossfire, and hungry hungry hippos. just sayin.

This is so cool! Finally a very simple and understandable example of what the Brownian motion is all about!
