This lecture brings experiment to bear on the previous theoretical discussion of bonding by focusing on hybridization of the central atom in three XH3 molecules. Because independent electron pairs must not overlap, hybridization can be related to molecular structure by a simple equation. The "Umbrella Vibration" and the associated rehybridization of the central atom is used to illustrate how a competition between strong bonds and stable...more

Kaplan says that every idea is repeatedly proposed. Timing of an idea is very important and very difficult to call. This involves enabling technologies, customers and trends in the investment industry to come together. He gives examples from TiVo and Amazon. An idea does not stand alone independent of timing and the investment industry, he adds.

Various sources of energy, energy storage, energy conversion, and the world's energy consumption are discussed. Power, or the rate at which a force does work on an object, is central to the conversation. Professor Lewin concludes with a few words on global...more

Professor Blight offers a number of approaches to the question of southern distinctiveness. The lecture offers a survey of that manner in which commentators--American, foreign, northern, and southern--have sought to make sense of the nature of southern society and southern history. The lecture analyzes the society and culture of the Old South, with special emphasis on the aspects of southern life that made the region distinct from the...more

The lecture focuses on the question of the metaphysical key to personal identity. What does it mean for a person that presently exists to be the very same person in the future? The first approach to answering this question is the "soul theory," that is, the key to being the same person is having the same soul. Difficulties with that approach are then discussed, independent of the question whether souls exist or not.
