Crazy university teacher :)

One of my teachers at my university used to be in this Macedonian hip-hop band called SAF. He is the "angry-sounding-looking" guy in the videos.

It is really surreal to see these music videos of a person who is teaching now at university level (stuff like quantum physics and sensor technology).
He is the best teacher I have ever had because he is really enganged in his teaching and there is just so much energy in his teachings :)

I don't know why, but I just wanted to share this with people here :)
