Study of physical effects in the vicinity of a black hole as a basis for understanding general relativity, astrophysics, and elements of cosmology. Extension to current developments in theory and observation. Energy and momentum in flat spacetime; the metric; curvature of spacetime near rotating and nonrotating centers of attraction; trajectories and orbits of particles and light; elementary models of the Cosmos. Weekly meetings include an...more
Lecture series examining Kant's Critique of Pure Reason. It remains a matter of controversy as to just what the central project of the Critique is, but surely one objective is to establish the character and range of objective knowledge in light of the limits of sense and reason. Lectures are intended to clarify the major claims advanced by Kant in this connection, and to test the arguments he adduces in their support.
Capitalism: Success, Crisis and Reform (PLSC 270) Professor Rae relates Marxist theories of monopoly capitalism to Schumpeter's theory of creative destruction. Both Marx and Schumpeter agree that capitalism is a system that is "incapable of standing still," and is always revising (or revolutionizing) itself. Professor Rae critiques Marxist determinism and other features of Marx's theories. To highlight Schumpeterian creative destruction,...more
Concerns about low fertility have been present in many countries for at least 100 years. A large population was considered essential to national power. But the issue is never simply a shortage of warm bodies: overall the world population has increased dramatically over this period and untold numbers would immigrate, if allowed. The issue is the number of the 'right sort' of people, defined as those having preferred national, religious, rac...more
Perry addresses the fact that an analytical way of thinking and approaching problems from his advanced degree in mathematics was a huge asset for his role as the Secretary of Defense. He stresses that the logic of going through the steps of problem solving will help one build objective decisions about the problem.
This is an introductory chemistry course for students with an unusually strong background in chemistry. Knowledge of calculus is recommended. Emphasis is on basic principles of atomic and molecular electronic structure, thermodynamics, acid-base and redox equilibria, chemical kinetics, and catalysis. The course also covers applications of basic principles to problems in metal coordination chemistry, organic chemistry, and biological chemistry.
This course is the second of a two-term sequence. The focus is on coding techniques for approaching the Shannon limit of additive white Gaussian noise (AWGN) channels, their performance analysis, and design principles. After a review of Principles of Digital Communication I and the Shannon limit for AWGN channels, the course begins by discussing small signal constellations, performance analysis and coding gain, and hard-decision and soft-d...more
This course includes a full set of lecture videos and a selection of problem solving videos. In the lecture videos, Professor Jonathan Gruber covers the principles of microeconomics conceptually, mathematically, and graphically, giving students a holistic understanding of the subject matter. He then moves on to more advanced topics in microeconomics to provide further insight into its many different applications. In the problem solving vid...more

Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)In this lecture Professor Wrightson considers the events leading to the execution of Charles I in 1649, and the republican regimes of 1649-60 (the Commonwealth and the Protectorate), with particular attention to the role of Oliver Cromwell. He begins with the unsuccessful attempts to negotiate a settlement with Charles I after the civil war, the in...more
Verma talks about how Savi was approached by the Defense Advanced Research Projects Agency (DARPA). DARPA has a small business research innovation program which awards grants to newer companies, and while the money comes with the requisite governmental red tape, it also allows companies to retain ownership of the business.
