In this lecture, Professor Diamond continues with the cerebral lobes and covers a variety of illnesses that occur in the cerebral lobes including neglect syndrome, Wernicke's Syndrome, and hallucinations. She also spends time on the temporal lobe, the occipital lobe, and the insula, its components and how it affects the body. Then she moves on to the composition, function and location of the eye and its constituents. She briefly covers...more

The Big Bang created the physical universe. Of course life is part of this physical universe, but the immediate building blocks of life are chemicals. Before the Big Bang, words such as “time” had no meaning, but even in the first few minutes there could be no chemistry since there were no atoms. The nuclei of some of the lighter elements formed within minutes, atoms some time later, and elements heavier than lithium were forged in the...more

We spent 4.5 years defining the customer experience, and we tried to put our money into things that mattered to people. Food is one example: I have never heard a single soul say that they haven't had a good meal, and so they'll book an airline ticket. This year, we'll serve 10 million customers. If we'd spent $5 on a meal for each customer, we'd have spent $50 million of food that wasn't appreciated. So we use humor to inform people that...more

Professor Snowden describes the historical detective work that went into the research and writing of Naples in the Time of Cholera, his study of the 1884 and 1911 epidemics of Asiatic cholera that struck Italy. The latter epidemic is of particular interest, because the official historiography of the disease has long confined its outbreaks in Western Europe to the nineteenth century. Through his investigation, Snowden discovered that there...more

Until now, the models we've used in this course have focused on the case where everyone can perfectly forecast future economic conditions. Clearly, to understand financial markets, we have to incorporate uncertainty into these models. The first half of this lecture continues reviewing the key statistical concepts that we'll need to be able to think seriously about uncertainty, including expectation, variance, and covariance. We apply...more

We consider games that have both simultaneous and sequential components, combining ideas from before and after the midterm. We represent what a player does not know within a game using an information set: a collection of nodes among which the player cannot distinguish. This lets us define games of imperfect information; and also lets us formally define subgames. We then extend our definition of a strategy to imperfect information games,...more

Part 1 - This Land is My Land: The philosopher John Locke believes that individuals have certain rights—to life, liberty, and property—which were given to us as human beings in the “the state of nature,” a time before government and laws were created. According to Locke, our natural rights are governed by the law of nature, known by reason, which says that we can neither give them up nor take them away from anyone else. Part 2 -...more

August 21, 2008 presentation by Stacey Bent for the Stanford University Office of Science Outreach's Summer Science Lecture Series. Meeting the world's growing energy needs in a sustainable fashion is one of the most pressing problems of our time. Professor Bent introduces the scope of the energy problem and some of the options for sustainable energy, then will focus on two main devices: solar cells and fuel cells. Solar cells convert...more

1) Population in China: Until recently, Chinese families did not much alter their fertility depending on life events such as deaths of children. However, under government prodding and eventually coercion, fertility dropped drastically in China in the 1970s, but to counteract momentum, the One-Child Policy started in 1979-80. 2) Population Growth and Economic Development: In Asia, rapid fertility drops have preceded economic booms by...more

In this lecture, Professor Kagan traces the development of Athens. He argues that Athens, like other poleis, undergoes political and social turmoil due to the rise of the hoplite farmer. This unrest is first seen in the attempted coup d'état of Cylon and the Law of Draco. Professor Kagan also points out that in response to these developments, Solon was made sole archon of Athens to establish peace in a time of unrest. It should also...more
