The Civil War and Reconstruction (HIST 119)

Professor Blight discusses the rise of abolitionism. Blight begins with an introduction to the genre of slave narratives, with particular attention to Frederick Douglass' 1845 narrative. The lecture then moves on to discuss the culture in which antebellum reform grew--the factors that encouraged its growth, as well as those that retarded it. Professor Blight then describes the movement towards radical abolitionism, stopping briefly on colonization and gradualism before introducing the character and ideology of William Lloyd Garrison.

Frontiers of Biomedical Engineering (BENG 100)

Professor Saltzman talks about the importance of vaccines, and particularly the role of bioengineering in vaccine development. He first addresses the question of "what is a vaccine" and the role of the immune system. He then describes the biological basis, symptoms, and history of smallpox as a devastating disease worldwide, and how--starting with the work of Edward Jenner--an effective vaccine was systematically developed from cow lesions. Next, methods to deliver vaccine to a wide population are introduced. Finally, Professor Saltzman touches on the possible reemergence of smallpox as weapon for bioterrorism.

Ever wondered how your phone knows exactly where you are, even in the middle of nowhere? In this lesson, we delve into the world of Medium Earth Orbit (MEO), a fascinating region of space located between 2,000 and 35,000 km above Earth. While far fewer satellites reside here compared to Low Earth Orbit (LEO), MEO is the critical home for Global Positioning System (GPS) satellites, despite the challenges posed by the treacherous Van Allen Belts. Discover why these navigation powerhouses orbit at 20,000 km, how they use precise timing and triangulation to pinpoint your location, and the global reliance on this vital technology.

🎯 Learning Objectives
• Identify the characteristics and challenges of Medium Earth Orbit (MEO), including the role of the Van Allen Belts.
• Explain why MEO is the optimal orbit for Global Positioning System (GPS) satellites.
• Describe the core mechanism by which GPS satellites determine a user's location through precise timing and triangulation.
• Recognize the global importance and widespread applications of GPS technology.
• Name other international satellite navigation systems beyond GPS.

Financial Markets (ECON 252)

Options introduce an essential nonlineary into portfolio management. They are contracts between buyers and writers, who agree on exercise prices and dates at which the buyer can buy or sell the underlying (such as a stock). Options are priced based on the price and volatility of the underlying asset as well as the duration of the option contract. The Black-Scholes options pricing model is one of the most famous equations in finance and offers a useful first approximation for prices for option contracts. Options exchanges and futures exchanges both are involved in creating a liquid and transparent market for options. Options are not just for stocks; they are also important for other asset classes, such as real estate.
