Scientists have just started to think about crackling noise in the past few years.
We have studied the crackling noise from crumpling
paper and from magnets.
Just for you, we've recorded the crackling noise in
Our friends have studied how the earth crackles - giving
Our site will start by exploring some examples of what we call crackling noise.
We will suggest some simple demonstrations, plus a couple of more
sophisticated experiments. We'll let you run some of the same computer models
that the science community has developed for studying various things that
crackle. And we'll show you some of the results of our supercomputer runs!
