Once again this year, Pavol Jozef Šafárik University in Košice once again took part in European Researchers’ Night, held on September 26, 2025, at OPTIMA shopping center in Košice. The university was represented by UPJŠ researchers with 17 stands and four expert lectures. The ceremonial opening of the event was attended by Prof. RNDr. Renáta Oriňaková, DrSc., Vice-Rector for Science, Research, and Projects at UPJŠ, who stated that scientists are well aware that progress does not come from perfectly organized systems, but quite the opposite.
“The greatest discoveries – whether in medicine, natural sciences, or humanities – often arose from breaking conventions and bold hypotheses. Albert Einstein would never have discovered the theory of relativity if he had not doubted the Newtonian physics. Today, we are witnessing how chaotic data from clinical studies are being transformed into knowledge that saves lives. We see how new algorithms that change our world are emerging from a seemingly disordered flow of information,” said Vice-Rector Prof. Oriňaková in her opening speech.
The main topic of European Researchers’ Night 2025 was chaos, its connection to knowledge and innovative processes, but also the perception of unpredictability around us. This year’s event aimed to show that the uncertainty and complexity associated with chaos are not obstacles to science, but rather tools for knowledge and drivers of technological progress.
Visitors could learn about the topics that scientists at our university are working on when visiting exhibition stands in OPTIMA shopping center,. Among the presenting researchers from UPJŠ was the Vice-Rector, who took a keen interest in all offered topics.
