The course in Linear Algebra is coming to an end. We only have one lecture left, and are now dealing with the most advanced topic in the course; quadratic forms.
On the 20th of December I will have the examination, and although there are three weeks left I already started studying. Going back to the beginning of the course does feel easy now when I have started to understand the topics and the notation. Scalar and vector products are no match for me anymore. It is strange how different every thing feels now after doing these abstract calculations for months, it just flows naturally now.
Tomorrow I and my project group present the Leaky Bucket project for the teachers. It is a project where we study control engineering and solve a simple problem. Our problem was to keep a level in a water tank constant with variable outflow. To do this we used a PID-regulator, a water pump, and a sensor.
During the project, we visited Tekniska Verken, the local power plant, to see how they use automatic control in their systems. It was interesting to see the fully automatic garbage ovens burn the garbage that comes from the city and produce electricity and heat that is fed back to the city. And those helmets really make you look hot!
