Hundreds of near-identical spiral patterns spontaneously can form on a centimeter square germanium chip. What’s more, small changes in experiment parameters, such as the thickness of the metal ...

It’s not easy to see it happen in a solid but let’s try it for a liquid and a gas. See if you can tell that heat makes molecules move! Place some ice in a large cup and add water to make ice water.

Hundreds of near-identical spiral patterns can spontaneously form on a centimeter square germanium chip. Moreover, small changes in experiment parameters, such as the thickness of the metal film ...
