# Zakharov Lectureship 2022

We are pleased to announce the "Zakharov Lectureship" in honor of Regents Professor Vladimir Zakharov's retirement, his contributions to the Program in Applied Mathematics and the Mathematics Department. The event will support an annual series of lectures during the spring in Tucson. **The first Zakharov Lectureship begins on Monday, January 31, 2022** and will be given by distinguished scientist, Professor Gregory "Grisha" Falkovich from the Weizmann Institute of Science. He will give a series of 5 lectures, once per week over 5 weeks on “Physical Nature of Information: How to get, send and forget information”. Please see schedule below:

**All lectures will be held at 4:00pm in the ENR2 building, Room S395:**

*This event is co-sponsored by Department of Mathematics, Program in Applied Mathematics, Department of Hydrology and Atmospheric Sciences, College of Science and the Data Science Institute.*

date | lecture topic |
---|---|

January 31, 2022 | Lecture 1: How the engineering question of thermal engine efficiency spawned two hundred years of ever-accelerating progress in fundamental science, communications and computations. Thermodynamic and statistical entropy. The puzzle of the second law of thermodynamics. How irreversible entropy growth appears from reversible flows in phase space via dynamical chaos. Entropy decrease and non-equilibrium fractal measures. |

February 7, 2022 | Lecture 2: Asymptotic equipartition as a universal mathematical tool of statistical physics and information theory. Information as a choice. Entropy as the rate of information transfer. Two greatest code inventions: alphabet and positional numeral system. Entropy of the language and the genetic code. |

February 14, 2022 | Lecture 3: Mutual Information as a universal measure of correlation and a channel capacity. Hypothesis testing and relative entropy. Second of law of thermodynamics made trivial. Distribution from information. Exorcising Maxwell demon, Landauer limit, fluctuating particle path in a potential. |

February 21, 2022 | Lecture 4: “What lies at the heart of every living thing is not a spark of life. It is information.” Flies and spies. Rate distortion theory and information bottleneck. Information is money and life: proportional gambling and phenotype switching. Learning by forgetting – renormalization group. |

February 28, 2022 | Lecture 5: Random walks and Brownian motion. Stochastic Web surfing and Google’s PageRank. Fluctuation theorems and modern forms of the second law of thermodynamics. |
