Plasma, the fourth state of matter, is by far the most abundant form of known matter in the universe. Its behavior is very different from the other states of matter we are usually familiar with. To understand it, a rigorous formalism is required. This is essential not only to explain important astrophysical phenomena, but also to optimize many industrial and medical applications and for achieving fusion energy on Earth.

This physics course, taught by world-renowned experts of the field, gives you the opportunity to acquire a basic knowledge of plasma physics. A rigorous introduction to the plasma state will be followed by a description of the models, from single particle, to kinetic and fluid, which can be applied to study its dynamics. You will learn about the waves that can exist in a plasma and how to mathematically describe them, how a plasma can be controlled by magnetic fields, and how its complex and fascinating behavior is simulated using today’s most powerful supercomputers.

This course is the first of two courses introducing plasma physics and its applications. After completing this course, you will have the prerequisites to enjoy Plasma Physics: Applications, which deals with plasma applications in astrophysics, industry, and nuclear fusion.

This course describes the processes by which mass, momentum, and energy are transported in plasmas, with special reference to magnetic confinement fusion applications.

The Fokker-Planck collision operator and its limiting forms, as well as collisional relaxation and equilibrium, are considered in detail. Special applications include a Lorentz gas, Brownian motion, alpha particles, and runaway electrons.

The Braginskii formulation of classical collisional transport in general geometry based on the Fokker-Planck equation is presented.

Neoclassical transport in tokamaks, which is sensitive to the details of the magnetic geometry, is considered in the high (Pfirsch-Schluter), low (banana) and intermediate (plateau) regimes of collisionality.

This course explores the following topics: derivation of elastic and plastic stress-strain relations for plate and shell elements; the bending and buckling of rectangular plates; nonlinear geometric effects; post-buckling and ultimate strength of cold formed sections and typical stiffened panels used in naval architecture; the general theory of elastic shells and axisymmetric shells; buckling, crushing and bending strength of cylindrical shells with application to offshore structures; and the application to crashworthiness of vehicles and explosive and impact loading of structures. The class is taught during the first half of term.

Firms such as Apple, Alibaba, Facebook, SalesForce, Uber and Yelp operate as platform ecosystems that match buyers and sellers, gain value and market share from network effects, and harness their users to innovate.

This course teaches you how to convert products to platforms and how to generate platform innovation. You will learn how to negotiate platform startup, convert existing businesses, and make vital decisions on issues of openness, cannibalization, and competition.

You will discover how to apply concepts from two sided networks, information asymmetry, pricing, intellectual property, and game theory to real problems.

This course is taught by the instructor who literally wrote the book on this topic, “Platform Revolution: How Networked Markets Are Transforming the Economy—and How to Make Them Work for You.”

This course is part of both the Digital Leadership and Product Management MicroMasters programs.

This philosophy course explores the origins of Western philosophy – a rich tapestry of ideas that began with the most noted ancient Greek and Roman philosophers.

By examining the work of these historic figures, students will attain a strong grasp of Western philosophy’s basic spirit. In doing so, they’ll cultivate deeper thinking abilities, explore noble values, and learn to contemplate the world around them in new ways.

This course provides continued work in the development of play scripts for the theater. Writers work on sustained pieces in weekly workshop meetings, individual consultation with the instructor, and in collaboration with student actors, directors, and designers. Fully developed scripts are eligible for inclusion in the Playwrights' Workshop Production.

This class introduces the craft of writing for the theater. Through weekly assignments, in class writing exercises, and work on a sustained piece, students explore scene structure, action, events, voice, and dialogue. We examine produced playscripts and discuss student work. This class's emphasis is on process, risk-taking, and finding one's own voice and vision.

Russell Stannard, an award-winning lecturer from the University of Warick, describes the use of these podcasting tools in a non-technical and step-by-step manner. The course is ideal for those who've always wanted to record and publish podcasts to the Web but lack the skills or knowledge to do it.<br />

Los estudiantes podrán comprender el papel del personalismo en la política del país, el de los militares como poder de facto, del factor petrolero como eje del sistema político, económico y social, y el del activismo internacional.

This course, the fourth installment of the multi-part Poetry in America series, explores the poetry of Emily Dickinson, one of America’s most distinctive and prolific poets. While Dickinson wrote nearly 2,000 poems during her lifetime, she chose never to publish, opting instead to revisit and revise her works throughout her lifetime.  Keeping this dynamic of self-revision in mind, we will consider a number of Dickinson’s poems—many seemingly in tension with one another—concerned with Nature, Art, the Self, and Darkness. We will travel to the Dickinson Collection at Harvard's Houghton Library, and to Amherst, Massachusetts, paying a visit to the house in which the poet lived and wrote until her death in 1886. Distinguished guests for this module include NBA athlete Jason Collins, dancers Damian Woetzel and Charles “Lil Buck” Riley, and President and CEO of the New America Foundation Anne Marie Slaughter, among others.

This literature course, the sixth module in the Poetry in America series, explores a diverse array of American Modernist poets and poems.  While “Modernism” is notoriously difficult to define, the movement spanned the decades from the 1910s to the mid-1940s, and the poetry of this period marked a clear break from past traditions and past forms.  

Throughout this module, we will encounter such poets as Robert Frost, T.S. Eliot, Marianne Moore, Langston Hughes, William Carlos Williams, Edna St. Vincent Millay, Claude McKay, Dorothy Parker, and Wallace Stevens. We will study how these poets employed the language of rejection and revolution, of making and remaking, of artistic appropriation and cultural emancipation. Traveling to the homes and workplaces of Robert Frost and Wallace Stevens; to the Poetry Foundation in Chicago, where the institution of American Modernism was born; and even exploring the River Thames in the London of Eliot's THE WASTE LAND, we will see the sites that witnessed—and cultivated—the rise of American Modernism.
