This change can only be made after approval by the Head of the Department. Units, vectors, one-dimensional kinematics, dynamics, work, equilibrium, sound, liquids, heat, electric potential and capacitance, direct current and alternating current, optics, modern physics, radioactivity.

**Lecturer**

This module is presented in English only. Students from all faculties are welcome to join us in our exploration of the universe from an earth-bound perspective. We reflect on the whole universe from the submicroscopic to the vast macroscopic and mankind’s modest position therein. To what degree is our happiness determined by stars? Echo's from ancient firmaments – the astronomy of old civilisations. The universe is born with a bang. Stars, milky ways and planets are formed. Life is breathed into the landscape on earth, but is there life elsewhere? The architecture of the universe – distance measurements, structure of our solar system and systems of stars. What does it look like on neighbouring planets? Comets and meteorites. Life cycles of stars. Spectacular exploding stars! Exotica like pulsars and black holes.
