On Tuesday, April 21st, Tornike Kadeishvili, Head of Scientific Board of Andrea Razmadze Mathematical Institute and Professor of Mathematics at ISET, gave a public lecture organized by ISET. The presentation was of “popular lecture” type, were Prof. Kadeishvili showed students how mathematics is used in modeling of economic events. More than 100 students and other interested individuals attended the lecture.

Prof. Kadeishvili started his presentation by showing his proof how efficiency of country’s governance can be increased through investing in education.

The mathematical proof of the above included a simple linear model of how country’s population is related to number of people who can govern. Afterwards, Prof. Kadeishvili explained to the audience how guitar strings can be related to simple market process of forming equilibrium. He used mathematical tools to show the difference between vibration of guitar strings and the process of forming equilibrium on the market. Furthermore, he brought the discussion to the difference between Julian and Gregorian calendars and involved the audience in calculating which one is more precise. Lastly, he discussed with the audience how time was accounted in books of history and showed how different events can be checked using mathematics and astronomy.

Prof. Kadeishvili is a renowned Georgian mathematician with large amount of publications in international impact factor journals. Throughout his career he has held number of vising positions in Germany, France, Spain, Mexico and United States. At ISET Prof. Kadeishvili teaches four math courses to first year students and advanced math course in mathematical logic to second year students. ISET would like to thank Prof. Kadeishvili for his extremely interesting presentation to students and other attendants.
