Scanned Lecture Notes on Percolation and Self-Organized Criticality

I have scanned and uploaded the remaining lecture notes on percolation. (Note that the scanned lecture notes on power laws already included some discussion of percolation.)

Note (5/30/16): I should have stated this explicitly previously, but the some notes on self-organized criticality are also available at the end of the notes on percolation.

Some New Sources Among the Useful Links

I have added links to some more notes and articles among the 'useful links', including a new review article (just posted on arXiv) on opinion dynamics.

Complex Systems Tarot Cards

Peter Dodds of University of Vermont has designed some spectacular complex systems tarot cards.

Words and Power Laws

I looked briefly again at Newman's article whence I got the example of word lengths and distributions. Here are a couple more comments on it:

(1) The circularity of the argument that we discussed is present directly in this paper, and Newman brings it up explicitly. If you want to pursue where things have progressed on this, you should look at the references to see what people have done.

(2) The error that I did make beyond the inherited logical issues are that when I introduced the example, I mistakenly used specific words in my introduction rather than length of words. That was just me messing up and unfortunately causing some confusion in the process.

I have posted homework sheet 3.

Class 1

Class 1 is now scheduled: It will take place Friday week 3 (Friday the 13th ... bwahaha) at noon in room S0.29 in the Mathematical Institute.

We will cover bits of homework sheets 1 and 2, and we will definitely discuss the papers I asked you to read.

Thank you for your patience with the confused situation involving classes.
