Third lecture quantum transport

was a fulfillment of duty. Most material given was quite difficult to follow, especially at the pace of the lesson. Also it is the most difficult chapter of the book. An easy solution would be just to talk about something else. Or present the topic only partly, just concealing the sharp edges and not drawing conclusions that wait to be drawn. If I do so, I would not be a scientist in a way I understand it. It is my duty to tell about this spectacular line of reasoning that starts from Gustav Kirchhoff, goes through treasures of and ends with curcuit theories of quantum transport. I am afraid if I do not give it nobody would. And this line of research will die replaced by primitive meso-nano-pico-amto incidentalies.

So suffered I, so students did. The first part of the lecture (double junction revisited) get eventually rather good, still felt interaction with the audience. The third (double junction again) was, to my understanding, yet easy to follow. Second (the road from quantum to classical) and forth (quantum circuit theory) are disastrous. I was trying to appeal to previous knowledge, to common sence, to anything: still was hard. Anybody can give me hints?

The student numbers are dropping, how many will I count next Friday? Good news come from problem-solving session of Ciprian. There were many, and many have attempted doing homework.
