# Sorry. I only barely understand it myself. Ok, percolation. Imagine you have five stacks of rocks, all different shapes but each stack is similar to itself. So, pebbles in one stack, stones in another stack, bigger rocks in another stack. Now you take those different sized rocks and put them all together. What you end up with is random. Shake it up and it’s still random. Now, instead of using pebbles and rocks, have five piles of perfect shapes of different sized. Instead of dumping them together, place them on top of one another in particular patterns until you find one that does what you want. Can you visualize the difference?

So, you can take a sample of the perfectly organized stuff and predict perfectly what its configuration will be elsewhere.

But if you take a sample of the randomly organized stuff, you can’t predict perfectly what the configuration will be elsewhere.

But oddly enough, sometimes it’s better to work with randomness when things are very complicated, such as turbulence, as we simply don’t have the computing power to do otherwise.

Thank you – that means a lot! I love finding things I barely understand myself and then trying to explain them. I find by explaining, it sharpens my own understanding of the subject.

I don’t know if I could do a curriculum but if somebody is ‘stuck’ where they are, I enjoy trying to help them get unstuck so that they can go forward again on their own.
