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

These lectures are from a Radio Frequency Identification (RFID) Academic Conference which was held at MIT in January 2006. The conference was in connection to the MIT course Special Topics in Supply Chain Management. This course is centered on how RFID systems will transform the business landscape, with a particular emphasis on the supply chain. The course will take an interdisciplinary approach to analyzing the various aspects of a modern...more

Hemingway, Fitzgerald, Faulkner (AMST 246)Professor Wai Chee Dimock traces Faulkner's appropriation of the epic genre through two conventions: the blurring of boundaries between humans and non-humans and the resurrection of the dead. She first reads Faulkner's minor character Tull and his relation to both mules and buzzards to draw out the "nature of manhood in poor whites." From Tull, she shifts focus to Jewel and suggests that his kinshi...more

Early Modern England: Politics, Religion, and Society under the Tudors and Stuarts (HIST 251)In this lecture, Professor Wrightson discusses witchcraft and magic. He begins with the context of magic beliefs in this period, introducing the 'cunning folk' who had reputations as healers and were often consulted. He then considers the specific problem of witchcraft, the use of magic to do harm, and its identification by the late medieval church...more

In this lecture Processor Lewin introduces elasticity and Young's modulus. The fractional length deformation of a material (the strain) depends on the force per unit area (the stress). The stress vs. strain dependence is described conceptually, then explored empirically. The speed of sound in a material depends on the stiffness and density of the material; from this follows the fundamental frequency at which a rod resonates. Professor Lewi...more

Professor McBride expands on the recently introduced concept of the wave function by illustrating the relationship of the magnitude of the curvature of the wave function to the kinetic energy of the system, as well as the relationship of the square of the wave function to the electron probability density. The requirement that the wave function not diverge in areas of negative kinetic energy leads to only certain energies being allowed, a p...more

Adaptive Evolution is driven by natural selection. Natural selection is not "survival of the fittest," but rather "reproduction of the fittest." Evolution can occur at many different speeds based on the strength of the selection driving it. These types of selection can result in directional, stabilizing, and disruptive outcomes. They can be driven by frequency-dependent selection and sexual selection, in addition to more standard types of ...more

One of the central questions in assessing Stalinism is whether or not the abuses of the latter were already present in the first years of the Russian Revolution. The archival evidence suggests that this is partly the case, and that even in its early stages Soviet Russia actively persecuted not just those who were believed to have profited unfairly, without laboring, but also non-Russian ethnic groups. Stalin, although not an ethnic Russian...more

The focus of the lecture is simple harmonic motion. Professor Shankar gives several examples of physical systems, such as a mass M attached to a spring, and explains what happens when such systems are disturbed. Amplitude, frequency and period of simple harmonic motion are also defined in the course of the lecture. Several problems are solved in order to demonstrate various cases of oscillation.

Breeding strategies differ both among males and females of the same species as well as among different species. The difference in breeding strategies among members of the same species can usually be linked to frequency dependence. If the species is at evolutionary equilibrium, the relative fitnesses of these different strategies will be identical. Differing strategies have been found at the level of the gamete as well as at the level of di...more

One way of understanding Napoleon's life is through attention to his Corsican origins. Although Napoleon himself would later disavow his earlier identification with the island in favor of French identity, many of his actions and attitudes agree with stereotypical notions of Corsican culture. Did Napoleon inaugurate the era of total war? This question, posed in a recent book, is up for debate. On one hand, the violence of the Revolution and...more
