Modern physics is an incredibly complex endeavour, where conducting research and calculations is impossible without top-tier equipment. One such device, the supercomputer at Vilnius University (VU), is among the most powerful scientific instruments in Lithuania, enabling researchers in physics, chemistry, and other fields to solve problems that would be impossible to crack without it. Associate Professor Mindaugas Mačernis, the head of the “HPC Saulėtekis” centre, quantum chemistry researcher, and populariser of quantum biology, says that supercomputers are changing not only the scientific process itself but also the very understanding of what modern physicists must be capable of.
