Hubskiing, listening music and researching which subjects to take when my classes start again next week.
I am starting my master in Electrical Engineering next week, thinking about all things low level electronic. Power electronics, microelectronics etc. Currently I am looking at subjects with names like 'Complex Analysis', 'Dynamical Systems', 'Classical Physics', 'Modern Physics and Optics' and 'Energy Degradation'.
No, not really. I just happen to find the possibilities of electricity and electronics amazing. Computers, factories and pretty much all of modern society cannot exist without this magic called electricity. And electronics are the things that harness that power on the most fundamental level. Quite a lot is possible if you know how these things work. That, and I want to be a modern day wizard :P
