On May 22, 2026, the final session of this semester’s inter-faculty scientific seminar “Modern Problems of Physics and Materials Science” was held remotely. The seminar is headed by Professor A.S. Opanasyuk, Head of the Department of Electronics and Computer Technology (ECT).
The seminar featured a presentation by Doctor of Technical Sciences, Professor of the ECT Department, Oleksiy Borysenko, titled “INFORMATION IN PHYSICAL PHENOMENA.” In his speech, the presenter introduced the audience to the fundamental definitions of information and its various types. He introduced the concepts of basic and internal constraints that shape products, objects, and systems, leading to the emergence of order, structure, and correlations within them. The structural theory of information and its core equation were also presented.
The speaker focused in more detail on physical information, linking it to the second law of thermodynamics and system entropy. Professor Borysenko also discussed the Landauer limit—the minimum energy dissipated when erasing one bit of information from memory, regardless of the physical implementation of the process. This causes a change in the system’s entropy by: S = kTln2. This results in the release of at least 2,7×10⁻²¹ $2.7 \times 10^{-21}\text{ J}$ of thermal energy at room temperature (300 K). Reaching the Landauer limit in the design of nanoelectronic devices is anticipated within the coming decades.
Additionally, the following presentations were delivered earlier this year during the seminar sessions:
“Proton Lithography: Prospects for Micro- and Nanostructure Production in Ukraine” (Presented by PhD, Research Fellow at the Institute of Applied Physics of the National Academy of Sciences of Ukraine, Hlib Yevhenovych Polozhiy);
“Nuclear-Physical Research Methods on an Analytical Accelerator Complex” (Presented by Doctor of Physical and Mathematical Sciences, Director of the Institute of Applied Physics of the National Academy of Sciences of Ukraine, Oleksandr Anatoliyovych Lebed).
