This course is an introduction to many of the central issues in a branch of philosophy called philosophy of mind.

Modal logic is the logic of necessity and possibility, and by extension of analogously paired notions like validity and consistency, obligation and permission, the known and the not-ruled-out. This a first course in the area. A solid background in first-order logic is essential. Topics to be covered include (some or all of) the main systems of propositional modal logic, Kripkean "possible world" semantics, strict implication, contingent identity, intensional objects, counterpart theory, the logic of actuality, and deontic and / or epistemic logic. The emphasis will be more on technical methods and results than philosophical applications.

This course provides an introduction to the study of environmental phenomena that exhibit both organized structure and wide variability - i.e., complexity. Through focused study of a variety of physical, biological, and chemical problems in conjunction with theoretical models, we learn a series of lessons with wide applicability to understanding the structure and organization of the natural world. Students will also learn how to construct minimal mathematical, physical, and computational models that provide informative answers to precise questions.

Explores the theory and practice of scientific modeling in the context of auditory and speech biophysics. Based principally on seminar-style discussions of the research literature, subject draws on examples from hearing and speech (e.g., cochlear and vocal-fold mechanics) to explore general, meta-theoretical issues that transcend the particular subject matter. Examples include: What is a model? What is the process of model building? What are the different approaches to modeling? What is the relationship between theory and experiment? How are models tested? What constitutes a good model?

This course models multi-domain engineering systems at a level of detail suitable for design and control system implementation. Topics include network representation, state-space models; multi-port energy storage and dissipation, Legendre transforms; nonlinear mechanics, transformation theory, Lagrangian and Hamiltonian forms; and control-relevant properties. Application examples may include electro-mechanical transducers, mechanisms, electronics, fluid and thermal systems, compressible flow, chemical processes, diffusion, and wave transmission.

In this class, students use data and systems knowledge to build models of complex socio-technical systems for improved system design and decision-making. Students will enhance their model-building skills, through review and extension of functions of random variables, Poisson processes, and Markov processes; move from applied probability to statistics via Chi-squared t and f tests, derived as functions of random variables; and review classical statistics, hypothesis tests, regression, correlation and causation, simple data mining techniques, and Bayesian vs. classical statistics. A class project is required.

This undergraduate course focuses on traditional algebra topics that have found greatest application in science and engineering as well as in mathematics.

This class provides an introduction to modern art and theories of modernism and postmodernism. It focuses on the way artists use the tension between fine art and mass culture to mobilize a critique of both. We will examine objects of visual art, including painting, sculpture, architecture, photography, prints, performance and video. These objects will be viewed in their interaction with advertising, caricature, comics, graffiti, television, fashion, folk art, and "primitive" art.

Applications of physics (Newtonian, statistical, and quantum mechanics) to fundamental processes that occur in celestial objects. Includes main-sequence stars, collapsed stars (white dwarfs, neutron stars, and black holes), pulsars, supernovae, the interstellar medium, galaxies, and as time permits, active galaxies, quasars, and cosmology. Observational data discussed. No prior knowledge of astronomy is required.

Physical metallurgy encompasses the relationships between the composition, structure, processing history and properties of metallic materials. In this seminar you'll be introduced to metallurgy in a particularly physical" way. We will do blacksmithing, metal casting, machining, and welding, using both traditional and modern methods. The seminar meets once per week for an evening laboratory session, and once per week for discussion of issues in materials science and engineering that tie in to the laboratory work. Students will begin by completing some specified projects and progress to designing and fabricating one forged and one cast piece."

This course analyzes major modern plays featuring works by Shaw, Pirandello, Beckett, Brecht, Williams, Soyinka, Hwang, Churchill, Wilson, Frayn, Stoppard, Deveare Smith, and Kushner. The class particularly considers performance, sociopolitical and aesthetic contexts, and the role of theater in the world of modern multimedia.

Selective survey of Latin American history from the wars of independence at the start of the nineteenth century to the present. Issues studied include: independence and its aftermath, slavery and its abolition, Latin America in the global economy, relations between Latin America and the US, dictatorships and democracies in the twentieth century, and revolution in Mexico, Cuba, and Central America.

A survey of major works of the twentieth century, beginning with Mahler, Schoenberg, Stravinsky, Bartok, and Ives; continuing with Varese, Webern, Hindemith, Prokofiev, among other composers. A general view of the current scene. Description from course home page:This subject covers a specific branch of music history: Western concert music of first sixty years of the twentieth century. Although we will be listening to and studying many pieces (most of the highest caliber) the goal of the course is not solely to build up a repertory of works in our memory (though that is indeed a goal). We will be most concerned with larger questions of continuity and change in music. We will also consider questions of reception, or historiography - that is, the creation of history and our perception of it. Why do we perceive much of this music, so much closer in time to us than Mozart or Beethoven, to be so foreign? Is this music aloof and separate from popular music of the twentieth century or is there a real connection (perhaps hidden)? The subject will continue to follow some topics of central interest to music before 1960, such as serialism and aleatory, beyond the 1960 cutoff. Conversely a few topics which get their start just before 1960 but which flourish later (minimalism, computer music) will be covered only in 21M.263.

Introduces the concepts and applications of navigation techniques using celestial bodies and satellite positioning systems such as the Global Positioning System (GPS). Topics include astronomical observations, radio navigation systems, the relationship between conventional navigation results and those obtained from GPS, and the effects of the security systems, Selective Availability, and anti-spoofing on GPS results. Laboratory sessions cover the use of sextants, astronomical telescopes, and field use of GPS. Application areas covered include ship, automobile, and aircraft navigation and positioning, including very precise positioning applications.

Consideration of some substantial twentieth-century poetic voices. Authors vary, but may include Moore, Frost, Eliot, Stevens, and Pound. This course considers some of the substantial early twentieth-century poetic voices in America. Authors vary, but may include Moore, Frost, Eliot, Stevens, and Pound. We'll read the major poems by the most important poets in English in the 20th century, emphazinig especially the period between post-WWI disillusionment and early WW II internationalism (ca. 1918-1940). Our special focus this term will be how the concept of "the Image" evolved during this period. The War had undercut beliefs in master-narratives of nationalism and empire, and the language-systems that supported them (religious transcendence, rationalism and formalism). Retrieving energies from the Symbolist movements of the preceding century, early 20th century poets began to rethink how images carry information, and in what ways the visual, visionary, and verbal image can take the place of transcendent beliefs. New theories of linguistics and anthropology helped to advance this interest in the artistic/religious image. So did Freud. So did Charlie Chaplin films. We'll read poems that pay attention both to this disillusionment and to the compensatory joyous attention to the image: to ideas of the poet-as-language-priest, aesthetic-experience-as-displaced-religious impulse, to poetry as faith, ritual, and form.

This course will consider the degree and nature of the modular organization of the mind and brain. We will focus in detail on the domains of objects, number, places, and people, drawing on evidence from behavioral studies in human infants, children, normal adults, neurological patients, and animals, as well as from studies using neural measures such as functional brain imaging and ERPs. With these domains as examples, we will address broader questions about the role of domain-general and domain-specific processing systems in mature human performance, the innateness vs. plasticity of encapsulated cognitive systems, the nature of the evidence for such systems, and the processes by which people link information flexibly across domains.
