The concepts introduced are: work, conservative forces, potential energy, kinetic energy, mechanical energy, and Newton's law of universal gravitation. A wrecking ball is converting gravitational potential energy into kinetic energy and back and forth. If released with zero speed, the wrecking ball should NOT swing higher than its height when it was released. Professor Lewin puts his life on the line by demonstrating this.

Professor Sylvia Ceyer discusses hybridization and chemical bonding. Using methyl nitrate as an example, Professor Ceyer describes how to find the lowest energy Lewis structure and explains bond symmetry, hybrid orbitals, and atomic orbitals. Moving onto intramolecular interactions, the discussion breaks down the origin of a bad hair day: hydrogen bonding, water, and keratin.

In this lecture Professor Sylvia Ceyer moves on from the wavelike properties of light, to the particle-like nature of light. To do so she covers the photoelectric effect in detail, discussing threshold frequency and kinetic energy vs. frequency. Planck's constant is discussed. The lectures concludes with a discussion of photon momentum and its relation to wavelength.

This course is designed to serve as a first course in an undergraduate electrical engineering (EE), or electrical engineering and computer science (EECS) curriculum. The course introduces the fundamentals of the lumped circuit abstraction. Topics covered include: resistive elements and networks; independent and dependent sources; switches and MOS transistors; digital abstraction; amplifiers; energy storage elements; dynamics of first- ...more

An intensive introduction to African American political thought that focuses on major ideological trends and political philosophies as they have been applied and interpreted by African Americans. Elements of the class include debates and conflicts in black political thought, historical contest of African American social movements, and discussions of the relationship between black political thought and major trends in Western thought. M...more

The disintegration of the Soviet Union resulted from a number of different factors. Three important ones are nationalism among Soviet satellite states, democratic opposition movements, and economic crisis. Along with these elements, the role of Mikhail Gorbachev should not be discounted. Although his attempt to reform communism was rejected, his reformist positions as Soviet premier helped open the way for full-fledged political dissidence...more
