A supercritical senile reinforced random walk with probability one, this walk gets stuck on a single (random) edge.
Site PercolationDefined by a single parameter, p. Bond percolation does not percolate at the critical point in 2 dimensions and above 19 dimensions, what about 3 dimensions? (use arrow keys to change p)
Urn modelDefined by a single parameter, p. Starting from one ball of each colour, after you have chosen a red ball n times then there will be (n+1)^p balls of that colour in the urn. Is there a difference between p<1, p>1 and p=1?
The voter model in two dimensionsAn interacting particle system in which each voter is influenced by their neighbour.

The problem with quotes on the internet is that it's hard to verify their authenticity (Abraham Lincoln)
A witch goes into a shop on knockturn alley to purchase a bag of thumbs. ``I reaaaally don't think you want thumbs'' says the shopkeeper, handing over the bag. The next day the witch returns to the shop and says ``It turns out that you were right, the thumbs were useless''. Looking sheepish the shopkeeper replies ``I hate to say I sold you toe, but I sold you toe''.
