Dark Side of the…Whah?

Over at the fact builders blog, the fact master discusses The Physics of….Pink Floyd. Being two areas I greatly enjoy, I was reminded by the fact builders picture of the cover of “The Dark Side of the Moon” of a little known piece of Pink Floyd strangeness.

More on Fixed Points

In a prior post I asked about the how the structure of fixed points of stochastic maps changes under composition of such maps. Robin provided an interesting comment about the setup, linking this question at least partially with zero error codes: R has at least one fixed point. If it’s unique, there need be no…
