From billionths of a second to cryptography and complexity

The Bosnian-Herzegovinian-American Academy of Arts and Sciences (BHAAAS) is once again organizing one of the largest scientific meetings in the region, BHAAAS Days, which will be held from June 21 to 24 at the Termag Hotel in Jahorina. The BHAAAS Days have been organized for ten years, and the jubilee of this important manifestation will be marked by interesting scientific lectures. Over a thousand participants are expected, including hundreds of lecturers who will take part in twenty-seven symposia in medicine and technical, natural, social, and human sciences. Thus, academician Dejan Milošević will talk about the latest research in atoscience, a new field of science that studies the movements and interactions with light of electrons in atoms. One attosecond is a billionth of a billionth of a second, and attoscience studies their movement. Academician Milošević is a regular professor of theoretical physics at the Faculty of Science and Mathematics of the University of Sarajevo. He is a regular member of the Academy of Sciences and Arts of Bosnia and Herzegovina, and since 2014 he has been a member of the European Academy of Sciences and Arts. This winner of the individual Sixth of April award of the city of Sarajevo for 2011, published 175 scientific papers, which, according to the Web of Science, were cited as many as 6300 times. Ismar Volić, professor of mathematics at Wellesley College in Boston, will tell us how to enable the transmission of a message in a way that only the sender and receiver can read it. This BH., the expert, who has given over 150 lectures on five continents, will speak on the topic "Cryptography and Privacy." The regulation of cryptography is an active and delicate debate with major repercussions for privacy, and at its center is the mathematics on which cryptographic algorithms rest. In addition, Professor Volić will hold two more lectures, one in the symposium of applied mathematics on the topic of topological data processing, a science that studies the "shape" of data, and the other in the symposium of education, where he will look at the importance of STEM (science, technology, engineering, and mathematics) in education, especially in developing countries. It is interesting that Volić is a Fulbright scholar, and under the auspices of that program, he is spending the current semester as a visiting researcher at the Department of Mathematics of the Faculty of Science and Mathematics in Sarajevo. Complexity is all around us, and it is one of the critical sciences for the 21st century, according to the professor at the University of North Carolina in Charlotte, Dr. Mirsad Hadžikadić. His research covers the areas of analytics, artificial intelligence, medical informatics, and complex systems. So far, he has published over 50 scientific papers and three books, organized international conferences, and is the chief editor for the journal Politics and Complex Systems. Dr. . Hadžikadić is the founding dean of the College of Information Technologies and the founding director of the Institute for Complex Systems. He currently holds the position of Executive Director of Analytical Programs. (https://www.radiosarajevo.ba/)
