Online lectures this week

As announced previously, this week's lectures are digital. I just added shorted movies to cover there material for tomorrow, 21 March: movie1, movie2, movie3, movie4, movie5
For convenience, I also added only the `blackboard' notes as a single pdf file.

Next week, we will continue with physical lectures starting from the point where the digital lectures stop -- but before doing so I will plan additional time to discuss this' week material. So make sure you watch the online lectures and prepare questions... ! :)
