After discussing the statistical basis of the law of mass action, the lecture turns to developing a framework for understanding reaction rates. A potential energy surface that associates energy with polyatomic geometry can be realized physically for a linear, triatomic system, but it is more practical to use collective energies for starting material, transition state, and product, together with Eyring theory, to predict rates. Free-radical...more

This lecture explains what an economic model is, and why it allows for counterfactual reasoning and often yields paradoxical conclusions. Typically, equilibrium is defined as the solution to a system of simultaneous equations. The most important economic model is that of supply and demand in one market, which was understood to some extent by the ancient Greeks and even by Shakespeare. That model accurately fits the experiment from the last...more

In this lecture, Professor Kagan continues to discuss the constitution of Athens. In particular, he explores the judicial workings of Athens. He describes in detail the effort of the Athenians to create a system of justice that would not only minimize tampering, in order to insure justice, but also maximize citizen participation. After this discussion, Professor Kagan comments on the role of women in Athens by looking at two types of sourc...more

In this lecture, Professor Mazzotta introduces Purgatory and proceeds with a close reading of Cantos I and II. The topography of Mount Purgatory is described, and the moral system it structures is contrasted with that of Hell. Dante's paradoxical choice of Cato, a pagan suicide, as guardian to the entrance of Purgatory ushers in a discussion of freedom from the standpoint of classical antiquity, on the one hand, and Judaism, on the other. ...more

Half a century before direct experimental observation became possible, most structures of organic molecules were assigned by inspired guessing based on plausibility. But Wilhelm Körner developed a strictly logical system for proving the structure of benzene and its derivatives based on isomer counting and chemical transformation. His proof that the six hydrogen positions in benzene are equivalent is the outstanding example of this chemical...more

Mating systems and parental care vary tremendously from species to species. Every species differs in how it protects its young from predators and provides its young with food, if it does so at all. The physical environment as well as behavioral dynamics in intraspecies relationships all influence parental care. Often the mating system, which sex is dominant in mating, and whether fertilization is external or internal will determine much of...more

Professor Diamond continues her discussion of the nervous system and begins by revisiting her discussion of the ascending path. She notes the presence of substantia gelatinosa in the area of the second neuron and describes the concept of homunculus, which is the upside-down representation of the body in the brain, and notes that this does not occur in the face for reasons unknown to neurologists. Professor Diamond then begins describing th...more

May 13, 2009 - Ed Moses, principal associate director of the National Ignition Facility, Lawrence Livermore National Laboratory, discusses current laser inertial fusion energy technology and its potential to scale up to nationwide energy production in the next 10 years.

April 25, 2008 lecture by Leah Buechley for the Stanford University Human Computer Interaction Seminar (CS547). Computational textile researchers weave, solder and sew electronics into cloth to build soft, flexible and wearable computers. Computational textiles or "e-textiles" is a young discipline, and developments in the field have so far been relegated almost exclusively to research labs in industry and academia. Lisa Buechley presents...more

Moore believes inertia is the legacy of successful innovation and the two must be managed as a single system in a business enterprise.

May 16, 2008 lecture by Rob Miller for the Stanford University Human Computer Interaction Seminar (CS547). Rob Miller discusses some of the explorations into keyword programming in the web automation domain, and also in other domains such as Java development. One surprising result is that programming language syntax often has relatively little information content, and can be inferred automatically from only a handful of keywords -- allowi...more
