  19. Omega and the End of the Universe 20.09.2026 55min

  Frontiers/Controversies in Astrophysics (ASTR 160)Class begins with a review of the issues previously addressed about the origin and fate of the universe. The role of gravity in the expansion of the universe is discussed and given as the reason why the rate of expansion cannot remain constant and will eventually slow down. The actual density of the universe is calculated using various methods. Finally, the unsolved problem of dark matter is addressed and two explanatory hypotheses are proposed. One is that the universe is comprised of WIMPs (Weakly Interactive Massive Particles) that fulfill two requirements: they have mass and do not interact with light. The second hypothesis is that dark matter is made of MACHOs (Massive Astrophysical Compact Halo Objects), which scientists have attempted to identify through gravitational lenses.00:00 - Chapter 1.

  America at 250: A History, DeVane Lecture, Class 24 - Reagan’s America 20.09.2026 1h

  The progress of the conservative movement in late 20th Century America is examined by Professor Beverly Gage in this lecture.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.

  15. The nature of death (cont.); Believing you will die 20.09.2026 50min

  Death (PHIL 176)The lecture explores the question of the state of being dead. Even though the most logical claim seems to be that when a person stops P-functioning he or she is dead, a more careful consideration must allow for exceptions, such as when one is asleep or in a coma. Professor Kagan then suggests that on some level nobody believes that he or she is going to die. As a case in point, he takes Tolstoy's famous character Ivan Ilych.00:00 - Chapter 1.

  15. Paradise Lost, Books V-VI 20.09.2026 59min

  Milton (ENGL 220)The description of human sexual hierarchy in Book Four of Paradise Lost is contrasted with the depiction of angelic hierarchy in Book Five. Both the Archangel Raphael's and Satan's accounts and theories of creation are examined.

The nature of matter and physical being in Heaven and Eden are explored with particular emphasis placed on the poem's monistic elements. Overall, Milton's willingness to question accepted religious, social, and political doctrine, even that which authorities in his own poem seem to express, is stressed.00:00 - Chapter 1.

  23. Other Constraints: The Cosmic Microwave Background 20.09.2026 53min

  Frontiers/Controversies in Astrophysics (ASTR 160)Reasons for the expansion of the universe are addressed at the start of this lecture, focusing especially on the acceleration of dark energy. Supernovae were the first evidence for the existence of dark energy. Two other proofs are presented. The first is the Cosmic Microwave Background, which is a form of electromagnetic radiation that is perfectly smooth and equal in all directions. It firmly supports the Big Bang theory. Projects attempting to measure it, such as COBE and WMAP, are discussed. Secondly, Large-Scale Clustering is introduced: by measuring the degree of clustering, astronomers hope to advance their understanding of dark energy and dark matter. Computer simulations of the evolution of the universe are shown.00:00 - Chapter 1. Implications of Research on Supernovae05:28 - Chapter 2. The Cosmic Microwave Background11:27 - Chapter 3.

  17. The Popular Front 20.09.2026 54min

  France Since 1871 (HIST 276)A plethora of Far Right and fascist organizations emerged in the wake of World War I. Economic depression, nationalism, anti-Semitism and xenophobia all played a part in this upsurge. On the left, the tension between communist revolutionaries and socialist reformers was reconciled, for a time, in the Popular Front government of Leon Blum. While the Popular Front would eventually fall, it pioneered many of the reforms and progressive measures that French workers enjoy today.00:00 - Chapter 1.

  Class 3: Capital Chapter 1: The Commodity, part 3 20.09.2026 56min

  How does value arise in exchange? What is labor in the capital system? Some simple forms of value. A chapter by chapter study of Marx’s powerful analysis in Capital: Critique of Political Economy, Volume 1. This book from 1872 is still the best guide to the predatory economic and social system within which we live. The book solves five basic mysteries in our social world. The mysteries are: why social classes struggle against one another, why human beings are in the thrall of things, how a quantity of money turns into more money without seeming to add anything, why some people are forced to work and the more they work the less they make proportional to their effort, and finally, and why it is so hard to transform the system for the better.  This course is taught by Paul North, Maurice Natanson Professor of German, Yale University. Prof. North is co-editor of the new English translation and critical edition of Capital Volume 1 by Karl Marx published in 2024 by Princeton University Press. https://press.princeton.edu/books/hardcover/9780691190075/capitalTo view other videos in this course, visit this link. https://youtube.com/playlist?list=PLh9mgdi4rNewd_0qe4c2lkzXZZQka_QnZ&si=CHOgjCcVD0K378kl Learn more about your ad choices.

  6. Arguments for the existence of the soul, Part IV; Plato, Part I 20.09.2026 42min

  Death (PHIL 176)The lecture begins with a continued discussion of the Cartesian argument and its weaknesses. The lecture then turns to Plato's metaphysical views in the context of his work, Phaedo. The key point in the discussion is the idea that in addition to the ordinary empirical world that we are familiar with, we posit the existence of a second realm in which the Platonic forms exist. These forms are the abstract properties that we attribute to physical objects, such as beauty, justice, goodness and so on. Since it is the soul that conceives of these Platonic forms and ideas, Plato argues that the soul not only outlives the body but lasts forever. It is perfect, immaterial and indestructible.00:00 - Chapter 1. Summary of the Cartesian Argument 04:57 - Chapter 2. Refuting the Cartesian Argument: The Morning and Evening Stars 19:25 - Chapter 3.
