Blog - Encrypting Pictures Using Chaotic Cellular Automata

Blog - Encrypting Pictures Using Chaotic Cellular Automata: Start by entering the password to produce a starting pattern of cells in the cellular automaton. Then run through 20 million iterations to generate a pseudorandom output. Superimpose this on the picture you want to encrypt and then send it.

Using chaos to model geophysical phenomena

Using chaos to model geophysical phenomena: This technique is based on so-called "transfer operators," which represent a complete description of the ensemble evolution of the fluid. The transfer operator approach is very simple to implement, they say, requiring only singular vector computations of a matrix of transitions induced by the dynamics.

Universe chaotic from very beginning | Science Blog: "The present-day universe is expanding and does so in all directions, Motter explained, leading to red shift of distant light sources in all three dimensions — the optical analog of the low pitch in a moving siren. The early universe, on the other hand, expanded in only two dimensions and contracted in the third dimension.

This led to red shift in two directions and blue shift in one. The contracting direction, however, was not always the same in this system. Instead, it alternated erratically between x, y and z.

“According to the classical theory of general relativity, the early universe experienced infinitely many oscillations between contracting and expanding directions,” Motter said."
