What does the graph look like when you convert each prime to binary and plot the ones versus the zeros?
Yesterday, I decided to plot the bifurcation diagram of the logistic equation. This is a famous plot from the 70s, with which many geeks will be familiar. It shows that simple systems can switch into "chaos mode" and begin to bifurcate wildly.
Today I decided to more deeply investigate this curious math thing I discovered (for myself) - Plotting the Fibonacci numbers by Prime numbers each by a given modulo. "Fibo-what? Mod-what? So what!", you say. :p
