12 - Evolutionary stability: social convention, aggression, and cycles
We apply the idea of evolutionary stability to consider the evolution of social conventions. Then we consider games that involve aggressive (Hawk) and passive (Dove) strategies, finding that sometimes, evolutionary populations are mixed. We discuss how such games can help us to predict how behavior might vary across settings. Finally, we consider a game in which there is no evolutionary stable population and discuss an example from nature.

07 - Nash equilibrium: shopping, standing and voting on a line
We first consider the alternative "Bertrand" model of imperfect competition between two firms in which the firms set prices rather than setting quantities. Then we consider a richer model in which firms still set prices but in which the goods they produce are not identical. We model the firms as stores that are on either end of a long road or line. Customers live along this line. Then we return to models of strategic politics in which it is voters that are spread along a line. This time, however

17 - Paradise IV, VI, X
This lecture deals with Paradiso 4, 6 and 10. At the beginning of Paradiso 4, the pilgrim raises two questions to which the remainder of the canto is devoted. The first concerns Piccarda (Paradiso 3) who was constrained to break her religious vows. The second concerns the arrangement of the souls within the stars. The common thread that emerges from Beatrice’s reply is the relationship between intellect and will. Just as Piccarda’s fate reveals the limitations of the will, the represent

Professor Mazzotta begins this lecture by recapitulating the ambivalent nature of Ulysses’ sin and its relevance to Dante’s poetic project. Inferno 27 is then read in conjunction with the preceding canto. The antithetical relationship between Dante’s false counselors, Ulysses and Guido da Montefeltro, anchors an overarching discussion of the relationship between rhetoric and politics. The latter half of the lecture is devoted to Inferno 28, where Dante’s preeminent sower of discord, B

Having dealt with the role of violence and the Supreme Court in bringing about the end of Reconstruction in his last lecture, Professor Blight now turns to the role of national electoral politics, focusing in particular on the off-year Congressional election of 1874 and the Presidential election of 1876. 1874 saw the return of the Democrats to majority status in the Senate and the House of Representatives, as voters sick of corruption and hurt by the Panic of 1873 fled the Republicans in droves.

AlgTop2: Homeomorphism and the group structure on a circle
This is the first video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic. Then we introduce the group structure on a circle, or in fact a general conic, in a novel way, following Lemmermeyer and as explained by S. Shirali. This gives a gentle intro to the definition of a group. It also uses Pascal's theorem in an interesting way, so we gi

10.4 Summary

By biological evolution we mean that many of the organisms that inhabit the Earth today are different from those that inhabited it in the past.

Natural selection is one of several processes that can bring about evolution, although it can also promote stability rather than change. It follows that natural selection is not the same thing as evolution.

The four propositions underlying Darwin's theory of evolution through natural selection are: (1) more individuals are produced than ca

Sumner on Growth and Economic Policy
Scott Sumner of Bentley University and the blog, The Money Illusion, talks with EconTalk host Russ Roberts about the last 30 years of economic policy and macroeconomic success and failure. Sumner argues that there was a neoliberalism revolution beginning in the 1980s around the world, an era of deregulation, privatization and falling marginal tax rates. Sumner argues that the states that liberalized the most had the most successful economic results. Roberts argues that it is difficult to assess

SP.601J Feminist Theory (MIT)
This course focuses on a range of theories of gender in modern life. In recent years, feminist scholars in a range of disciplines have challenged previously accepted notions of political theory such as the distinctions between public and private, the definitions of politics itself, the nature of citizenship, and the roles of women in civil society. In this course, we will examine different aspects of women's lives through the life cycle as seen from the vantage point of feminist theory. In addi
