The master in Physics and Astronomy (MSc) (μεταπτυχιακό σε Physics and Astronomy (MSc)) provides a comprehensive education in physics covering particle physics, general relativity, astrophysics, and the study of complex systems. Physics aims at understanding the world around us by observing it from the smallest scales to the scale of the universe itself. From those observations, models are built to allow us to understand, explain and eventually predict the behavior of nature.
