Paper Abstract

Paul Davies, a highly respected theoretical physicist recently stated that "the essence of life is information." 1 I will describe how the essence of information is plasticity, that information is encoded energy requiring what neurophysiologists call plasticity. Plasticity is the ability of neurons through their synapses to have memory, learn, adapt and evolve in response to their environment. I will show that Ovonic memories, both optical and electrical, have rich and deep new physics that make them cognitive devices and therefore open up a huge new field of chalcogenide-based intelligent computers, intelligence that works in a similar manner to the brain. We have shown that the plasticity necessary for an intelligent opto-electronic computer is a function of energy pulses, whether electrical or optical.
