In the heart of scientific excellence of Zagreb, on the stretch connecting Horvatovac and Bijenička streets, a unique event is being prepared that will bring science closer to everyone, from curious students to the academic community and the wider public. This is the #SciHill event, scheduled for Friday, May 16, 2025, which will transform this well-known part of the city, home to key scientific institutions, into a vibrant center of discovery, innovation, and learning. From 9 a.m. to 8 p.m., visitors will have the opportunity to dive into the fascinating world of science through a rich and interactive program.

This initiative is not a random collection of events; it is the fruit of the synergy of three pillars of Croatian science and education: the Faculty of Science (PMF) of the University of Zagreb, the Institute of Physics (IF), and the Ruđer Bošković Institute (IRB). These institutions, each with its rich history and specific contributions, have been shaping scientific thought and educating generations of experts for decades. #SciHill represents the crown of their long-standing collaboration, uniting popular and successful programs such as "Day and Night at the PMF," "IF Open Day," "IRB Open Day," and "Frizbijada." By creating this integrated platform, the goal is to provide a comprehensive experience of science, stimulate curiosity, and inspire, especially young people, for careers in STEM fields (science, technology, engineering, and mathematics).

Science Hill: Epicenter of Knowledge and Innovation

The name "Science Hill" is not just a metaphor. The area of Horvatovac and Bijenička cesta in Zagreb truly represents a physical and intellectual center where knowledge is generated and transmitted. Numerous faculty departments, research laboratories, and institutes that form the backbone of Croatian scientific production are located here. #SciHill uses precisely this unique concentration of scientific intellect to provide visitors with direct insight into the world of research. The event extends through the laboratories of the Institute of Physics and various departments of the PMF, as well as outdoors, where research stations will be set up in meadows under tents, creating a dynamic and accessible environment from Horvatovac all the way to Bijenička cesta 46.

The central mission of this event is multifaceted: to demystify science, make it tangible and exciting, and encourage young people to think about science as a future vocation. By enabling direct contact with scientists and researchers, #SciHill aims to break down potential barriers and show that the scientific world is accessible and open to new ideas. Through play, experiment, and inspirational encounters, visitors will discover that knowledge is not just an abstract concept, but a powerful tool for understanding the world around us and the foundation for personal and professional development. The ultimate goal is to contribute to the creation of the most valuable capital of any modern society: excellent experts, advanced knowledge, and innovative technologies that drive progress.

Synergy of Institutions: PMF, IF, and IRB

The Faculty of Science of the University of Zagreb (PMF) is a fundamental institution of higher education and scientific research in the field of natural sciences and mathematics in Croatia. With its numerous departments – Biological, Physical, Geophysical, Geographical, Geological, Chemical, and Mathematical – the PMF covers a wide spectrum of scientific disciplines. Their program "Day and Night at the PMF" traditionally attracts thousands of visitors eager for knowledge, offering a plethora of lectures, workshops, and demonstrations tailored to all ages.

The Institute of Physics (IF) is a leading scientific institution in Croatia dedicated to research in various fields of physics, including solid-state physics, surface physics, atomic and molecular physics, and plasma physics. It is known for its cutting-edge research and modern equipment, and its "Open Days" are always an opportunity to peek into the world of contemporary physics experiments and theories.

The Ruđer Bošković Institute (IRB) is the largest Croatian research institute in the field of natural and biomedical sciences and technology. Its multidisciplinarity encompasses research in physics, chemistry, molecular biology and medicine, marine and environmental research, and computer science. "IRB Open Days" are known for presenting the latest scientific achievements and technologies, often with an emphasis on interdisciplinary research and the application of science in solving societal challenges. "Frizbijada," as a joint event of IF and IRB, has already demonstrated the success of the collaboration of these institutions in popularizing science.

By uniting these renowned programs into #SciHill, a unique opportunity is created for visitors to experience at one place the breadth and depth of scientific research taking place in Zagreb, and to meet the people behind these discoveries.

In Fifth Gear: The Theme of Speed at PMF

A special backbone of this year's program at the Faculty of Science will be the phenomenon of speed. Speed, as a universal driver, permeates every aspect of our existence and the universe – from the smallest particles to cosmic expanses, from biological processes to technological innovations. Visitors will have the opportunity to explore how speed shapes the natural laws and technological processes that define our world.

Imagine the speed of light, the cosmic speed limit – at #SciHill you will be able to participate in experiments that attempt to measure it or at least comprehend its incredible value. The speed of chemical reactions, crucial for life and industry, and how enzymes, natural catalysts, accelerate these processes many times over, will be explored. From lightning-fast reflex reactions that protect our bodies, through the speed at which information spreads through the nervous system, to super-fast trains that change the perception of distance and space – these are all manifestations of speed that will be investigated. Visitors will be able to challenge a simulated storm, earthquake, or even a tsunami and observe the destructive, yet formative forces of nature that act at different speeds.

The technological aspect of speed will be equally represented. You will be able to control robots and see how the speed and precision of their movements enable the automation of complex tasks. The fascinating possibility of "running on water," probably through a demonstration of the properties of non-Newtonian fluids, will intrigue many. Creative individuals will find their niche by creating their own geographical maps, while fans of the digital world will be able to see what rocks from the popular game Minecraft look like in reality, connecting the virtual with the geological speeds of rock formation. Of course, a visit to the PMF's Botanical Garden is unmissable, where one can observe the speed of growth and development of the plant world, as well as the adaptation of plants to different living conditions.

The slogan "It's time to shift into fifth gear! From the fastest animals to technological wonders, we bring you stories that will take you into the world of fascinating accelerations. Our departments have prepared lightning-fast scientific discoveries for you. Come and feel how science is racing forward!" perfectly summarizes the spirit of this part of the event.

Interactive Learning and Direct Experience

#SciHill is not conceived as passive observation; the emphasis is on interaction and personal experience. Laboratories will open their doors, and scientists will step out of their usual work environments to become guides and mentors. Visitors, especially pupils and students, will have the opportunity to ask questions, participate in experiments, handle equipment (under supervision), and find out firsthand what it means to be a scientist. Workshops will be designed to encourage critical thinking, problem-solving, and teamwork – skills crucial not only for a scientific career but also for life in the 21st century.

An atmosphere of a knowledge festival is expected, where curiosity will be the main currency, and discoveries the reward. The "Science Hill" area will be filled with stands, demonstrations, short lectures, and presentations, tailored to different age groups and levels of prior knowledge. Science playrooms will be organized for the youngest, while older pupils and students will be able to find information about study programs and scientific career opportunities. For all those planning to visit Zagreb for this event, it is useful to research accommodation options in advance.
