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
Lecture 2 provides an introduction to the idea of poverty traps. Instructor: Esther Duflo
In this lecture, Esther Duflo talks about social experiments done to understand what interventions work best to mitigate world poverty. Instructor: Esther Duflo
In this lecture, Esther Duflo covers malnutriton and the nutrition-based poverty trap, including the relationship between productivity and nutrition. Instructor: Esther Duflo
In this lab, the class does a charcoal burn from start to finish, loading the drum, lighting it, and sealing it after some of the burn. While the burn is going on, they grate yucca to make a binder and make briquettes using the contents from a previous burn. Speaker: ...
This lecture reviews solar cooker technology and a case study in D-Lab's Creative Capacity Building workshops. The session ends with final thoughts on trip preparation, including how to get good information from community partners, and how to pack. Speaker: Amy ...
This video contains three student team presentations previewing their plans for upcoming visits to Nicaragua and El Salvador community partners, and feedback from instructor Amy Banzaert about those plans. Speaker: MIT Students, Amy Banzaert
Four student teams (juice bag sealer, charcoal barrel improvement, solar charger for cell phones, rice dehusking) give final presentations and demonstrations of their projects, at the D-Lab Spring Showcase event. Speaker: MIT Students
Description: The main focus is the microscopic picture of waves. This lecture discusses the energy transport by waves, by using the Maxwell's equations in different electric/magnetic fields and between different interfaces. Instructor: Prof. Gang Chen
Description: Students learn to solve the Boltzmann equation in the classical limit under relaxation time approximation in this lecture. Students also learn to derive the Fourier law, Newton shear law, and the electron transport process with the Ohm's Law. Instructor: ...
Description: This lecture continues discussion on energy transport when it travels perpendicularly to a film. It also provides solving Boltzmann equation with consideration of classical size effects under circumstances of heat carriers colliding with boundaries. ...
Instructor: Dennis Freeman Description: The final Signals and Systems lecture explains how audio playback evolved from the fragile Edison cylinder phonograph to durable modern optical disks, through the application of digital signal processing concepts.
This lab consists of three modules: - Characterize the peak power output of the solar cell - Measure how power output of a solar panel changes with the angle of light - Measure how solar panel efficiency drops when the panel is shaded Students also get more instruction ...
In this pre-lab lecture, students learn the basics about how photovoltaic solar panels work. They also learn about various solar thermal technologies, and the advantages to using SODIS bags for solar water disinfection. Speaker: Amit Gandhi
In this lab, students use soda bottles, wire, and magnets to construct small wind turbines on wooden bases. They use the Savonius wind turbine design and troubleshoot various problems that come up, finally calculating voltage and current when finished. Speaker: Amit ...
Instructor: Dennis Freeman Description: Today's lecture continues the discussion of control systems by demonstrating how feedback loops can add speed and bandwidth to the LM741 op-amp, and allow better control of a robot arm's angular position.
Description: In this lecture, Esther Duflo discusses nutrition as a hidden trap. Instructor: Esther Duflo
In this pre-lab lecture, students learn about the sun and its pluses and minuses as a source of energy, and the various inefficiencies throughout the process of harvesting, storing, then using solar power. Speaker: Amit Gandhi
Description: The lecture first continues discussion on liquids. It investigates transport properties of bulk liquids, and different forces and potentials between particles and surfaces in liquids. It also explores current research in solar-cells. Instructor: Prof. Gang ...
Description: The discussion on statistical physics continues in this lecture. The instructor gives several examples in different ensemble cases, and also an application example in gas molecule. Instructor: Prof. Gang Chen
Description: This lecture continues previous discussion of wave propagation in thin films, and determines the energy exchange between two points. It also explores various examples in application of tunneling. Instructor: Prof. Gang Chen
