  Introduction to Ancient Greek History (CLCV 205)In this lecture, Professor Kagan finishes up his description of the Spartan constitution. He argues that Sparta had a mixed constitution and gained great power due to alliances that the Spartans made with their neighbors. After the discussion of Sparta, Professor Kagan examines Athens and the development of the Athenian constitution. In addition, he shows how different these two poleis were. Finally, Professor Kagan discusses the emergence of the hoplite class in Athens and the failure of Cylon to make himself tyrant of Athens.00:00 - Chapter 1. The Spartan Assembly10:53 - Chapter 2.

  15. Athenian Democracy 16.09.2026 1ч 16мин

  Introduction to Ancient Greek History (CLCV 205)In this lecture, Professor Kagan describes the mechanics of the Delian League and its transformation into the Athenian empire.

  13. Toni Morrison, The Bluest Eye 16.09.2026 56мин

  The American Novel Since 1945 (ENGL 291)Professor Hungerford draws a contrast between Toni Morrison and most of the writers studied up to this point in the course by pointing out how, for an African-American woman writer in particular, language is a site of violence. For all of her power to recuperate the voices of the oppressed, the novelist must be wary of the ways that breaking the silence, too, can constitute an act of invasion. As in the case of Pynchon, the word in The Bluest Eye enacts a near-physical touch; this is its pleasure and its danger. With inimitable complexity and grace, Morrison weaves her narrative around a young black girl who, in the void of her social persona, constructs a beautiful and poisonous fiction.00:00 - Chapter 1.

  18. Imperfect information: information sets and sub-game perfection 16.09.2026 1ч 22мин

  Game Theory (ECON 159)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, and use this to construct the normal form (the payoff matrix) of such games. A key idea here is that it is information, not time per se, that matters. We show that not all Nash equilibria of such games are equally plausible: some are inconsistent with backward induction; some involve non-Nash behavior in some (unreached) subgames. To deal with this, we introduce a more refined equilibrium notion, called sub-game perfection.00:00 - Chapter 1. Games of Imperfect Information: Information Sets18:56 - Chapter 2.

  5. The Rise of the Polis (cont.) 16.09.2026 1ч 13мин

  Introduction to Ancient Greek History (CLCV 205)In this lecture, Professor Donald Kagan tells the story of the emergence of the polis from the Dark Ages. He shows that by the time of the poet Hesiod, there is already a polis in place. He describes the importance of the polis in the Greek world and explains that it was much more than a mere place of habitation; it was a place where there was justice, law, community, and a set of cultural values that held Greeks together. Finally, Professor Kagan argues, following the lead of Victor David Hanson, that the polis came to be chiefly through the emergence of a new man: the hoplite farmer.00:00 - Chapter 1.

  6. Efficient Markets vs. Excess Volatility 16.09.2026 1ч 15мин

  Financial Markets (ECON 252)Several theories in finance relate to stock price analysis and prediction. The efficient markets hypothesis states that stock prices for publicly-traded companies reflect all available information. Prices adjust to new information instantaneously, so it is impossible to "beat the market." Furthermore, the random walk theory asserts that changes in stock prices arise only from unanticipated new information, and so it is impossible to predict the direction of stock prices. Using statistical tools, we can attempt to test the hypotheses and to predict future stock prices. These tests show that efficient markets theory is a half-truth: it is difficult but not impossible for some people to beat the market.00:00 - Chapter 1.

  3. The Dark Ages (cont.) 16.09.2026 1ч 19мин

  Introduction to Ancient Greek History (CLCV 205)In this lecture, Professor Kagan addresses what scholars call the Homeric question. He asks: what society do Homer's poems describe? He argues that in view of the long oral transmission of the poems, the poems of Homer probably reflect various ages from the Mycenaean world to the Dark Ages. More importantly, close scrutiny of the poems will yield historical information for the historian. In this way, one is able to reconstruct through the poems, to a certain extent, the post-Mycenaean world. Finally, Professor Kagan says a few words on the heroic ethic of the Greek world.00:00 - Chapter 1. The Importance of Homeric Poems13:08 - Chapter 2.

  11.6 | Navigating AI/ML Challenges in Medical Software Development — Medical Software Course 16.09.2026 20мин

  In this lesson, Professor John Onofrey delves into the unique practical issues and challenges that Artificial Intelligence and Machine Learning applications encounter throughout the medical software life cycle. He contrasts these with traditional software development, highlighting the critical role of training data, risk assessment from sources like distributional shifts and adversarial attacks, and the necessity for robust system design to manage the inherent 'black box' nature and potential failures of AI/ML models in clinical settings.🎯 Learning Objectives• Differentiate the unique requirements and challenges of AI/ML applications within the medical software life cycle from traditional software.• Identify and understand critical risk factors for AI/ML systems, such as distributional shifts, adversarial attacks, and performance drift.• Explain the intrinsic link between training data, model development, and the importance of reproducibility and quality control.• Articulate the concept of treating AI/ML components as "unsafe" and designing robust systems with failure mitigation strategies, including human-in-the-loop approaches.• Describe the distinct workflows for training and deploying AI/ML models and the need for continuous post-market monitoring.

  Milton (ENGL 220)In this second lecture on Paradise Regained, the three temptations are examined and Milton's unusual departure from their account in the Gospel of Luke is discussed. The poem's tacit assertion of the superiority of knowledge and ethics over action is probed. Considerable time is spent examining the Son's rejection of classical literature. Finally, Book Four's allusion to the riddle of the sphinx serves as a springboard to a consideration of the poem's Oedipal elements.00:00 - Chapter 1.

  16. Backward induction: reputation and duels 16.09.2026 1ч 22мин

  Game Theory (ECON 159)In the first half of the lecture, we consider the chain-store paradox. We discuss how to build the idea of reputation into game theory; in particular, in setting like this where a threat or promise would otherwise not be credible. The key idea is that players may not be completely certain about other players' payoffs or even their rationality. In the second half of the lecture, we stage a duel, a game of pre-emption. The key strategic question in such games is when; in this case, when to fire. We use two ideas from earlier lectures, dominance and backward induction, to analyze the game. Finally we discuss two biases found in Americans: overconfidence and over-valuing being pro-active.00:00 - Chapter 1. Establishing a Reputation: Selten's Chain Store Paradox20:56 - Chapter 2.
