"One might think that, once we know something is computable, how efficiently it can be computed is a practical question with little further philosophical importance. In this essay, I offer a detailed case that one would be wrong. In particular, I argue that computational complexity theory---the field that studies the resources (such as time, space, and randomness) needed to solve computational problems---leads to new perspectives on the nature of mathematical knowledge, the strong AI debate, computationalism, the problem of logical omniscience, Hume's problem of induction, Goodman's grue riddle, the foundations of quantum mechanics, economic rationality, closed timelike curves, and several other topics of philosophical interest. I end by discussing aspects of complexity theory itself that could benefit from philosophical analysis."

A Renaissance in Economics The American President Ronald Reagan once quipped, “The nine most terrifying words in the English language are, ‘I’m from the government and I’m here to help.’” I get the same shivers when someone introduces themselves as an economist.

From the mid 40s to the mid 50s
Coronet Instructional Films were always ready to provide social guidance for teenagers on subjects as diverse as
dating,
popularity,
preparing for being drafted, and
shyness, as well as to children on
following the law,
the value of quietness in school, and
appreciating our parents. They also provided education on topics such as the connection between
attitudes and health,
what kind of people live in America,
how to keep a job,
supervising women workers,
the nature of capitalism, and
the plantation System in Southern life. Inside is an annotated collection of all 86 of the complete Coronet films in the
Prelinger Archives as well as a few more. Its not like you had work to do or anything right?

Researchers at the
New England Complex Systems Institute say they've uncovered a pattern that triggers riots wherever it's found. What is that pattern?
The price of food. When it rises to a certain level, social unrest & violence are soon to follow. According to their calculations the food price index is due to peak in August of 2013, assuming no corrective action is taken. The original paper is
here.

Right Wing astroturfing A non-scientific analysis of the patterns in forum board discussions on a variety of topics. The gist: discussions of issues in which there's money at stake (like
climate change,
public health and corporate
tax avoidance) are often characterised by amazing levels of abuse and disruption by rightwing libertarians who are pro-corporate, anti-tax, anti-regulation. Discussions of issues in which there's little money at stake tend to be a lot more civilised than debates about issues where companies stand to lose or gain billions.
