Iosif Refulyevich Entinzon / Иосиф Рефулевич Ентинзон

Iosif Refulyevich Entinzon was born in Kyiv in 1947. He graduated with honors in Chemistry from Lomonosov Moscow State University in 1970. In 1981, he defended his Candidate dissertation, “Modeling the Physical Stage of Radiolysis in Condensed Media,” at the L. Ya. Karpov Institute of Physical Chemistry in Moscow.

From 1971 to 1987, he worked at the L. V. Pisarzhevsky Institute of Physical Chemistry of the Academy of Sciences of the Ukrainian SSR, serving successively as an engineer, senior engineer, and researcher. From 1987 to 1999, he was a senior researcher at the Institute of Surface Chemistry of the National Academy of Sciences of Ukraine.

His research concerns the passage of ionizing radiation through heterogeneous targets and computer modeling of the spectral and dose distributions of gamma photons and fast electrons in structural materials and materials used in solid-state electronics. According to his résumé, he has published more than 70 scientific articles.

From 1999 to 2011, he taught in the Faculty of Biology at the International Solomon University in Kyiv as a docent, or associate professor. His courses covered chemistry, higher mathematics, and physics, including mathematical methods in biology and his own course, Theory of Errors.

Theory of Errors (Lectures) is teaching material by I. R. Entinzon, dated Kyiv, 2023. The course focuses on processing measurement results, beginning with random, systematic, and gross errors and proceeding to probabilistic and statistical methods of estimation.

Topics include random variables, the normal distribution, parameter estimation, the central limit theorem, confidence intervals, a numerical example, and the method of least squares. The lectures connect mathematical concepts with a practical question: how to report a measurement result and its uncertainty on a sound basis.
