DESCRIPTION:Leon Chua\, University of California\, Berkeley\n \nAbstract:
 \nThe first part of this talk presents the axiomatic basis of the ideal me
 mristor and its generalized experimental definition via its pinched hyster
 esis loops. A fundamental new theorem will be presented which asserts that
  all non-volatile memories that did not require a power supply\, or quantu
 m-mechanical-effects\, must exhibit a continuum range of memories\, which 
 can be tuned to emulate synapses.\n\nIn particular\, we will show that the
  modulation of neurotransmitters during learning is akin to tuning the con
 ductance of a memristor. We will emulate the classic Kandel Aplysia learni
 ng experiments\, as well as Bliss-Lomo's long term potentiation (LTP) phen
 omenon with a single memristor. Moreover\, we will solve the heretofore un
 resolved Hodgkin-Huxley Paradox on the shocking gigantic inductance they h
 ad measured from the squid axon by showing the potassium and sodium ion ch
 annels which Hodgkin and Huxley had erroneously identified as time-varying
  conductances are in fact time-invariant memristors.\nFurthermore\, we wil
 l present an experimental voltage-divider circuit containing only one Ag/A
 gInSbTe/Ta memristive synapse capable of mimicking Pavlov's conditioning e
 xperiments on dogs\, thereby demonstrating the associative learning phenom
 enon.\n\nThe second part of this talk presents a new law of thermodynamics
 \, dubbed the Principle of Local Activity\, which allows the entropy to de
 crease\, and provides the rigorous mathematical foundation for the generat
 ion of action potentials in the Hodgkin-Huxley equation\, as well as Alan 
 Turing's seminal paper on the emergence of complex phenomena and morphogen
 esis.\n\nWe conclude this talk by showing that intelligence and life must 
 operate in a Goldilock's zone of local activity\, dubbed the edge of chaos
 .\n\nAbout the speaker:\nLeon Chua received his MSEE degree from MIT in 19
 61. He received his PhD degree from the University of Illinois\, Urbana-Ch
 ampaign in 1964\, with a thesis titled 'Nonlinear Network Analysis - The P
 arametric Approach'. He became an Assistant Professor of Electrical Engine
 ering at Purdue University in 1964\, and was promoted to Associate Profess
 or in 1967. In 1971\, he joined the faculty of the University of Californi
 a\, Berkeley\, where he has remained ever since.\n\nDr. Leon O. Chua is wi
 dely recognized as the father of nonlinear circuit theory and cellular neu
 ral networks (CNN). The CNN architecture is the only one implemented into 
 a practical fully-programmable chip for solving ultra-high-speed pattern r
 ecognition and image processing problems. The CNN universal machine chip i
 s capable of a thousand times greater performance in speed\, weight and po
 wer consumption than related technologies. Dr. Chua also invented a five-e
 lement circuit for generating chaotic signals. Aptly named the Chua Circui
 t\, it is used by many researchers to design secure communications systems
  based on chaos. Dr. Chua was the first to conceive the theories behind\, 
 and postulate the existence of\, the memristor. Thirty-seven years after h
 e predicted its existence\, a working solid-state memristor was created by
  a team at Hewlett Packard.\n\nAn IEEE Fellow\, he is a past president of 
 the IEEE Circuits and Systems Society and former editor of the IEEE Transa
 ctions on Circuits and Systems. He is the Editor of The International Jour
 nal of Bifurcation and Chaos.\n\nDr. Chua has nine honorary doctorate degr
 ees from prestigious universities across the world\, like the AGH Universi
 ty of Science and Technology (Poland)\, University of Frankfurt (Germany)\
 , University of Tokushima (Japan)\, to name a few. In 2002 he was named am
 ong the top fifteen most cited engineering authors. He has won numerous aw
 ards\, like the IEEE Centennial Medal in 1985\, the IEEE Circuits and Syst
 ems Society Golden Jubilee Medal in 2000\, the IEEE Third Millenium Medal 
 and the IEEE Neutral Networks Pioneer Award\, also in 2000 and the IEEE Gu
 stav Robert Kirchhoff Award in 2005.
