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

Although molecular mechanics is imperfect, it is useful for discussing molecular structure and energy in terms of standard covalent bonds. Analysis of the Cambridge Structural Database shows that predicting bond distances to within 1% required detailed categorization of bond types. Early attempts to predict heats of combustion in terms of composition proved adequate for physiology, but not for chemistry. Group- or bond-additivity schemes a...more

Work by Wöhler and Liebig on benzaldehyde inspired a general theory of organic chemistry focusing on so-called radicals, collections of atoms which appeared to behave as elements and persist unchanged through organic reactions. Liebig's French rival, Dumas, temporarily advocated radicals, but converted to the competing theory of types which could accommodate substitution reactions. These decades teach more about the psychology, sociology, ...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

A perennial favorite is the idea of time travel. What would happen if we could go back in time and alter the future a la “Back to the Future”? The great narrative of the history of life has a complexity rife with subplots and twists, many of which we will never uncover. Yet somehow the story of life on Earth began with a prebiotic ooze and ended with the awe-inspiring diversity of life we see today – including us. But like any story, th...more

Kaplan talks about the different kinds of risks (market, financial and technical) that an entrepreneur faces when starting a company. The trick is to get the risk out as soon as possible. If your product is not obvious to the market you must go out into the market and explain it to them, he says. He shares the example of TiVo.

There is a distinct possibility that humans are currently part way through an evolutionary transition between individuals and groups. The conflict between these two units of selection and levels of organization, between biology and culture, may explain some of the tensions in modern human life. Examples of selfishness and altruism exemplify how these types of selection act on humans.
