If the early years of the twentieth century were marked by a general consensus that a major war was impending, no similar consensus existed concerning the likely form that war would take. Not only the carnage of World War I, but also the nature of its alliances would have been difficult to imagine. Indeed, in 1900 many people would have predicted conflict, rather than collaboration, between France and Britain. The reasons for the eventual ...more
In this lecture, Professor Kagan describes the aftermath of the Peloponnesian War and how the Spartans began to dominate other GreekÂ poleis, instead of liberating them. The Spartan general Lysander at this point not only grows in influence and power, but also follows an aggressive plan to establish pro-Spartan, oligarchical governments. However, according to Professor Kagan, this fact angered many cities. Therefore, Thrasybulus, along wit...more
Professor Sylvia Ceyer devotes this lecture to discussing the wavelike properties of radiation. She covers oscillation vs. propagation in light, calculating the speed of a wave, and the visible light spectrum. She then moves on to the wave nature of light, highlighting a few new terms including superposition, constructive, and destructive interference. In conclusion, the wavelike properties of radiation are discussed as they relate to You...more
The Roman Empire in the West collapsed as a political entity in the fifth century although the Eastern part survived the crisis.. Professor Freedman considers this transformation through three main questions: Why did the West fall apart -- because of the external pressure of invasions or the internal problems of institutional decline? Who were these invading barbarians? Finally, does this transformation mark a gradual shift or is it right ...more
In this lecture, two important issues are addressed in the context of Locke's Second Treatise. First, there is discussion on the role of the executive vis-a-vis the legislative branch of government in Locke's theory of the constitutional state. Second, Locke's political theories are related to the American regime and contemporary American political philosophy. The lecture concludes with John Rawls' book, A Theory of Justice, and how his ge...more
Professor Mazzotta introduces students to the general scheme and scope of the Divine Comedy and to the life of its author. Various genres to which the poem belongs (romance, epic, vision) are indicated, and special attention is given to its place within the encyclopedic tradition. The poem is then situated historically through an overview of Dante's early poetic and political careers and the circumstances that led to his exile. Professor M...more
After mentioning some legal implications of chirality, the discussion of configuration concludes using esomeprazole as an example of three general methods for producing single enantiomers. Conformational isomerism is more subtle because isomers differ only by rotation about single bonds, which requires careful physico-chemical consideration of energies and their relation to equilibrium and rate constants. Conformations have their own notat...more
Francis talks about the social problem surrounding vaccines. People are only scared of a disease and willing to endure vaccination when they see evidence of the disease. Because vaccines are very effective at wiping out diseases, he notes, society does not tend to be interested with vaccines. In general, society neglects preventative activities, but instead invests huge amounts of money when people actually do get sick, he adds.
In this lecture, the first of two about geometric data structures, we'll talk about two major problems-point location and range searching-and tie them to several major data structural techniques: persistence, retroactivity, dynamization of augmentation through weight balance, and fractional cascading.In (planar) point location, we need to preprocess a planar map to support queries of the form "which face contains this point?" This problem ...more
The discussion on the origins of inequality in the Second Discourse continues. This lecture focuses on amour-propre, a faculty or a disposition that is related to a range of psychological characteristics such as pride, vanity, and conceit. The Social Contract is subsequently discussed with an emphasis on the concept of freedom and how one's desire to preserve one's freedom is often in conflict with that of others to protect and defend thei...more
The transparent tissues of the eye allow light to reach the retina. This highly metabolic tissue requires oxygen delivered by the blood vessels, which are damaged by disease. Diabetic retinopathy is the commonest cause of blindness in the working-age population and in later life hypertension adds to this toll. The eyes maybe the mirror of the soul, but they certainly are a window into our general health. This lecture traces the story f...more
