Note that the lectures on-line are not self-explaining. They contain no figures nor deeper explanation! Note that the lectures are "upgraded" also backwards, so you can get better versions even of the first lectures now.

Some things still need to be brushed up.

There are dark blue pages with the main text and light blue pages with some more detailed explanation, sometimes there are more of them. In the end of the last one there should be an arrow to get back to the main text. I would be grateful for any comments! I have figures on my PC version but I don't know how to make it working on the net should the files not be enormous. I would also be grateful if some Windows expert could recommend me how to insert figures in some more effective way.
