MIT OpenCourseWare (OCW) is a web-based publication of virtually all MIT course content. OCW is open and available to the world and is a permanent MIT activity. The material available reflects almost all the undergraduate and graduate subjects taught at MIT. Visit OCW
Description: This lecture starts with dictionaries in Python, considers the problems with using a direct-access table, and introduces hashing. The lecture discusses hashing with chaining, which is one way of dealing with collisions. Instructor: Erik Demaine
Description: This lecture covers table resizing, amortized analysis, string matching with the Karp-Rabin algorithm, and rolling hashes. Instructor: Erik Demaine
This lecture continues the discussion from lecture 12, and also includes material on how families make decisions about family planning. Instructor: Esther Duflo
This lecture covers gender discrimination and uneven gender ratios in various countries, including India. Instructor: Abhijit Banerjee
Description: This lecture covers experiments conducted to understand savings and borrowing in Kenya and the Phillippines. Instructor: Abhijit Banerjee
Note: This video is from the Fall 2007 class. This lecture continues discussion of Charlie Chaplin, comparing his films to those of Buster Keaton. Outline: - Keaton vs. Chaplin - Three passages - Cops (1922) - The Gold Rush (1925) - City Lights (1931) - Modern Times ...
Three student teams give 20 minute presentations about their week-long visits to community partners, in which they test and refine various energy project designs. Speaker: MIT Students, Amy Banzaert
Four student teams (juice bag sealer, charcoal burn, solar charger for cell phones, rice dehusking) present initial designs, preliminary test results, and next steps, and get feedback from guest reviewers and mentors. Speaker: MIT Students
Lecture 1 provides an introduction to the study of global poverty. The class discusses the challenges of world poverty. Instructor: Abhijit Banerjee
This lecture discusses some of the most effective and cheapest ways to promote good health, such as bednets, immunization and breast feeding. Instructor: Esther Duflo
In this pre-lab lecture, students learn about using organic matter to create biogas for cooking and when biodigesters are advantagous vs impractical. Finally, they go over a specific biodigester design in great detail, learning how each part works. Speaker: Amit Gandhi
In this lab, students connect several small PV panels together into a circuit. They then take their solar arrays outside and compare the output of each individual panel to that of the array as a whole, and measure the effect shading has on the array. Speaker: Amit ...
Description: This lecture continues to explore the repulsive force between particles and surfaces in liquids and learn more on electrokinetics. It also investigates the size effect on phase transition. Instructor: Prof. Gang Chen
Description: In this lecture, students learn to calculate the energy carried by electromagnetic (EM) waves, and understand how EM waves propagate in a medium and at an interface. Instructor: Prof. Gang Chen
Description: This lecture provides more details on the application of Snell's Law at one single interface; later, more discussion of the wave propagation in multi-layered structures, for instance thin films. It also gives out information about the first midterm exam. ...
Description: The lecture introduces various approximate ways to tribute all effects to different boundaries/interfaces conditions, and covers topics in energy conversion and coupled transport processes. It also provides details of the second midterm exam. Instructor: ...
Description: This lecture uncovers the basic science of semiconductor devices and solar cells, including p-n junction and photovoltaic effects. Also, it explains the phenomenon of Shockley-Queisser limit. Instructor: Prof. Gang Chen
Description: This lecture explores drivers of movements, such as interest groups and changing preferences, and how they affect environmental movements as well as the formation of public policy, efforts, and parties. Instructor: Richard Schmalensee
Description: This lecture focuses on the politics of regulation through a series of case discussion surrounding the EPA and setting emissions standards in response to air pollution, coal emissions, and acid rain. Instructor: Richard Schmalensee
Description: This intro lecture gives an overview of the course and the research in the field of nanoscience and technology. It starts with review of the classical laws related to energy transport processes, and introduces microscopic pictures of energy carriers. ...
