The Chance of Error in Atomic Sized Computers

The first thing that you would worry about when things get very small is Brownian motion--everything is shaking about and nothing stays in place. How can you control the circuits then? Furthermore, if a circuit does work, doesn't it now have a chance of accidentally jumping back? If we use two volts for the energy of this electric system, which is what we ordinarily use, that is eighty times the thermal energy at room temperature (kT=1/40 volt) and the chance that something jumps backward aga...

 The Pandemonium Software Architecture

This essay, while dealing with computational theory, provides a model for how the brain functions. The Pandemonium Model, where multiple processes try to answer a patter, with a administrative function picking the best answer, provides an excellent model for the environment in which the brain evolved, with useful components being selected over poor or noisy components.
