  24. Twilight of the Polis (cont.) and Conclusion 25.09.2026 1ชม. 23นาที

  Introduction to Ancient Greek History (CLCV 205)In this lecture, Professor Kagan tells the story of the rise of Philip and describes his early actions: unifying Macedon, defeating barbarian armies, and creating a new, professional, national army. According to Professor Kagan, through these actions, Philip was able to make inroads into the Greek world. What made these inroads more effective was Philip's uncanny talent for diplomacy and the fighting between the various poleis. Eventually, the Greeks under the efforts of Athens and Demosthenes decided to face Philip in the battle of Chaeronea. The battle, though close, was won by Philip and his Macedonian forces. Finally, Professor Kagan evaluates the actions of Demosthenes and concludes that his actions should be judged as a noble endeavor of one who loved freedom.00:00 - Chapter 1.

  12. Real Estate Finance and its Vulnerability to Crisis 24.09.2026 1ชม. 14นาที

  Financial Markets (ECON 252)Real Estate is the biggest asset class and of great importance for both individuals and institutional investors. An array of economic and psychological factors impact real estate investment decisions and the public has changing ideas of real estate as a profitable investment. People's demand to buy a home by taking on long-term debt, called a mortgage, is often tied with the overall health of the economy and financial markets. In recessions, home buying tends to fall and the opposite holds in a strong economy. Commercial real estate, held indirectly by the public through partnerships and real estate investment trusts (REITs), is vulnerable to similar speculative activity. The most recent real estate boom illustrates the speculative nature of real estate, and its relation to financial and economic crises.00:00 - Chapter 1. Introduction 02:17 - Chapter 2.

  24. Students' Choice Novel: Jonathan Safran Foer, Everything is Illuminated 24.09.2026 52นาที

  The American Novel Since 1945 (ENGL 291)In this first of two lectures on the students' choice end-of-semester novel, Jonathan Safran Foer's Everything is Illuminated (2002), Professor Hungerford models several methods for approaching and evaluating a new work of fiction. She shows how Foer borrows and adapts themes and styles from other authors on the syllabus in service to his ambition as a writer to demonstrate the power of narrative fiction to address the great historical traumas of our time. In thus attempting to marry the nineteenth-century social novel with Postmodernist, or late Modernist, techniques, Foer participates in an emerging tradition that risks the confusion between resonant emotion and sentimental cliché.00:00 - Chapter 1.

  2. Richard Wright, Black Boy 24.09.2026 57นาที

  The American Novel Since 1945 (ENGL 291)Professor Amy Hungerford continues her discussion of Richard Wright's classic American autobiography, Black Boy. Through a close analysis of key passages, she demonstrates an oscillation in the narrative between the socioeconomic deprivations and racial jeopardy confronting its characters, and the compensations to be found in sensual experience, the imagination, and in particular, the power of words. Dramatizing the editorial struggle evident in letters between Wright and Book-of-the-Month-Club-President Dorothy Canfield Fisher, Professor Hungerford shows the high stakes of Wright's uncompromising portrait of America's failed ideals at a time when those ideals are being tested during the Second World War.00:00 - Chapter 1.

  America at 250: A History, DeVane Lecture, Class 1 – The Road to 250 24.09.2026 52นาที

  America at 250: A History. Class 1 “The Road to 250”Introduction to the course with all three professors setting the stage. Recorded in Yale’s Battell Chapel. This one-time-only course examines U.S. history from 1776 to the present, in advance of the nation’s semiquincentennial (or 250th birthday) in 2026. Taught jointly by Professors Joanne Freeman, David Blight, and Beverly Gage, the course emphasizes the history of the nation-state and the contested nature of American national identity. All three scholars will deliver the course’s first and final lectures together, as an introduction and a wrap-up. In between, they will each deliver eight lectures individually based on their areas of expertise. Joanne Freeman, the Alan Boles, Class of 1929 Professor of History and American Studies, and an expert in the revolutionary and early national periods of American history, will cover the period from the Revolution up through the 1830s, touching on such topics as the birth of party politics, the nature of “Jacksonian democracy,” and the rise of the reform and protest movements.David Blight, Sterling Professor of History and African American Studies and one of the country’s foremost authorities on the history of slavery and the Civil War, will cover the Civil War era up through Reconstruction and the emergence of the Jim Crow laws.Beverly Gage, John Lewis Gaddis Professor of History, who is currently writing a book on the nation’s past to mark the 250th anniversary of the signing of the Declaration of Independence, will pick up in the 1890s and continue through the end of the 20th century, addressing debates around immigration, wealth inequality, and the creation of the social welfare state. The course explores U.S. political history broadly conceived–not just as a realm of presidents and elections and wars (though there will be plenty of those) but as a conversation across time between citizens about what the United States is, was, and was meant to be. It proceeds from the premise that the American Revolution was the first but not the last radical act of national reimagining in U.S. history. A copy of the course syllabus with required readings can be downloaded at the bottom of the page at this link: https://president.yale.edu/committees-programs/devane-lectures/america-at-250-a-history To view all the classes in the DeVane Lecture series, go to this playlist link: https://youtube.com/playlist?list=PLh9mgdi4rNezTQrY_6XMNBWaZqLRdgpoq&feature=shared Learn more about your ad choices.

  18. Biomechanics and Orthopedics 24.09.2026 51นาที

  Frontiers of Biomedical Engineering (BENG 100)Professor Saltzman introduces the material properties of elasticity and viscosity. He describes two separate experimental setups to measure the elasticity and the viscosity of a material. Material elasticity can be defined in terms of stress-strain property, and defines the Young's modulus (E), which is the slope of the stress-strain curve. Fluid viscosity, on the other hand, is described by shear stress. When modeling any material, the spring can be used to represent an ideal elastic material and the dashpot an ideal viscoelastic material. All biomaterials contain some combination of these properties and can be described by physical models that consist of both spring and dashpot.00:00 - Chapter 1. Introduction03:16 - Chapter 2.

  5. Insurance: The Archetypal Risk Management Institution 24.09.2026 1ชม. 21นาที

  Financial Markets (ECON 252)Insurance provides significant risk management to a broad public, and is an essential tool for promoting human welfare. By pooling large numbers of independent or low-correlated risks, insurance providers can minimize overall risk.
