The Faculty of Science (PMF) is an institution whose educational and research excellence has been recognised both domestically and internationally. The Faculty of Science of the University of Zagreb provides high quality and effective university education in the fields of natural science and mathematics at all three levels of university studies. The study programmes are founded on research and the most recent scientific knowledge, whereas teaching is an important part of innovation and international collaboration. Among our highest values are good and motivated students who, with their knowledge and skills, should become the protagonists of economic and social development of the Republic of Croatia and elsewhere. Scientific research is carried out within the fields of natural sciences (fields: mathematics, physics, geology, chemistry, biology, geophysics, and interdisciplinary natural sciences) and interdisciplinary areas of science (geography), accounting for about 20% of the total scientific production of the University of Zagreb. The Faculty of Science is organised into seven departments, each of which possesses great autonomy in scientific, teaching, and professional activity. The seven departments of the Faculty of Science (Biology, Physics, Geophysics, Geography, Geology, Chemistry, and Mathematics), organized into 28 divisions, are home to about 4000 students enrolled in undergraduate, integrated undergraduate and graduate, and graduate university studies within 35 study programmes and about 1000 students at seven postgraduate studies and one postgraduate specialist study. The PMF also comprises the Seismological Service and its seismological stations all over Croatia, the mareographic station in Bakar, the geomagnetic observatory in Lonjsko polje, and the green jewel located in the very heart of Zagreb – the Botanical Garden.
