International Politics in the Korean Peninsula reviews several archetypes of politics and introduces contemporary issues of the inter-Korean relationship. Video lectures will be in Korean, with English subtitles. Discussions, quizzes, and other course content will be in English. This course is the first part of International Politics in the Korean Peninsula; the second part will start this Fall.
The course is introduced with two cases where politics brought tragedies: the hyper-inflation in Zimbabwe and the political idolization in North Korea. These two cases provide a good answer to why we study politics.
The central content of the course is organized into two modules. First, it will start with several chapters from Records of the Grand Historian (Chinese: 史記), Plutarch's Lives, and History of the Three Kingdoms (한국어: 삼국사기; Chinese: 三國史記) to find out four archetypes of politics: value creation/distribution in a political entity, conflict and cooperation among political entities, development and maintenance of an identity in a political entity, and leadership selection in an entity.
The second module of the course will link the four archetypes of politics with contemporary issues of inter-Korean politics and political events in North Korea. These issues will include the Korean Crisis in 2012, the arms race between the two Koreas, the power succession and the simultaneous (nuclear and economic) build-up strategy in North Korea, and upcoming political events.
Course videos are presented in Korean with English subtitles.

Vision may feel effortless: you open your eyes, and the world appears. But the process of focusing light into image on the back of the eye and translating it into meaningful nerve signals is incredibly complex. The retina and visual cortex are packed with intricate processing circuitry, and have been a mystery to neuroscientists for centuries. Now, answers are beginning to emerge.
Today, the visual system is often called the model system for neuroscience: its findings are relevant to all other areas and to investigating the deeper mysteries of the brain’s microstructure and function. In this course, we take you from the physics of focusing light onto the retina, to the processing of colors, form, and motion, and finally to the interpretation of visual information in the cortex. We distill the mysteries of the visual system by posing questions and investigating them in a series of thematic, animated videos. This journey through the eye, retina and brain will (quite literally) change how you see the world.

Composites are used in many industries today to enable high-performance products at economic advantage. These industries range from space to sports and include manufactured products for aircraft, transportation, energy, construction, sports, marine, and medical use. There are many material, economic and aesthetic advantages to using composites, but a solid knowledge of the physical properties, including the mechanics, tooling, design, inspection & repair, and manufacturing options is required for working in this medium as they are intrinsically linked.
This course provides an introduction to the fundamentals of composite materials for high performance structures from the point of view of Aerospace engineering design, manufacturing, and repair. It is designed to address critical areas of composite technologies that focus on materials, manufacturing, mechanics, design, inspection, and repair. In this course students will learn how composite materials achieve properties of strength, weight ratios and durability that surpass aluminum in aircraft design. For these high performance applications engineers typically rely on laminated structures, which are built up from many varying layers of ply-materials. Using this process the mechanical properties of the composite part can be tailored to specific applications resulting in significant weight and cost savings. Tailoring specific properties and designing innovative laminate structures highlights the multidisciplinary nature of this industry and how it touches the expertise of many disciplines including engineers, mechanics, and inspection specialists.
After successfully completing this course, students will be able to identify the unique characteristics of composites and understand how advanced composite structures are designed, manufactured and maintained.

Separately, EdX has applied for a license to offer courses to learners in the Crimea region of Ukraine, but we are awaiting a determination from OFAC on that application. We are deeply sorry the U.S. government has determined that we have to block these learners, and we are working diligently to rectify this situation as soon as possible.
There is no doubt that technological innovation is one of the key elements driving human progress.
However, new technologies also raise ethical questions, have serious implications for society and the environment and pose new risks, often unknown and unknowable before the new technologies reach maturity. They may even lead to radical disruptions. Just think about robots, self-driving vehicles, medical engineering and the Internet of Things.
They are strongly dependent on social acceptance and cannot escape public debates of regulation and ethics. If we want to innovate, we have to do that responsibly. We need to reflect on –and include- our societal values in this process. This course will give you a framework to do so.
The first part of the course focuses on ethical questions/framework and concerns with respect to new technologies.
The second part deals with (unknown) risks and safety of new technologies including a number of qualitative and quantitative risk assessment methods.
The last part of the course is about the new, value driven, design process which take into account our societal concerns and conflicting values.
Case studies (ethical concerns, risks) for reflection and discussions during the course include – among others- nanotechnology, self-driving vehicles, robots, AI smart meters for electricity, autonomous weapons, nuclear energy and CO2capture and coolants. Affordable (frugal) innovations for low-income groups and emerging markets are also covered in the course. You can test and discuss your viewpoint.
The course is for all engineering students who are looking for a methodical approach to judge responsible innovations from a broader – societal- perspective.

Life on our planet is diverse. While we can easily recognize this in our everyday surroundings, an even more diverse world of life can be seen when we look under a microscope. This is the world of microorganisms. Microorganisms are everywhere, and although some are notorious for their roles in human disease, many play important roles in sustaining our global environment. Among the wide variety of microorganisms, here we will explore those that thrive in the most extreme environments, the extremophiles.
In this course, we will discover how diverse life is on our planet and consider the basic principles that govern evolution. We will also learn how we can classify organisms. Following this, we will have a look at several examples of extreme environments, and introduce the microorganisms that thrive under these harsh conditions. We will lay emphasis on the thermophiles, extremophiles that grow at high temperatures and will study how proteins from thermophiles can maintain their structure and function at high temperatures.
Politics of Freedom: The Civil War, 1861-1865 narrates the history of the American Civil War. While it examines individual engagements and the overall nature of the military conflict, the focus is less on the battlefield than on political, social, and economic change in the Union and the Confederacy. Central to the account are the road to emancipation, the role of black soldiers, the nature of Abraham Lincoln’s wartime leadership, internal dissent in both the North and South, the changing position of women in both societies, and the war’s long-term economic and intellectual impact. We end with a look at the beginnings of Reconstruction during the conflict.
This course is part of the XSeries, Civil War and Reconstruction, which introduces students to the most pivotal era in American history. The Civil War transformed the nation by eliminating the threat of secession and destroying the institution of slavery. It raised questions that remain central to our understanding of ourselves as a people and a nation – the balance of power between local and national authority, the boundaries of citizenship, and the meanings of freedom and equality. This XSeries will examine the causes of the war, the road to secession, the conduct of the Civil War, the coming of emancipation, and the struggle after the war to breathe meaning into the promise of freedom for four million emancipated slaves. One theme throughout the series is what might be called the politics of history – how the world in which a historian lives affects his or her view of the past, and how historical interpretations reinforce or challenge the social order of the present.
This mini-course focuses on the question of accountability in public schools.
Who is accountable for student outcomes? Should we blame the schools or hold the students themselves accountable? Who determines the standards for accountability – the federal government or the individual states?
The demand for accountability in U.S. education resulted in No Child Left Behind and has shaped the Common Core debate. Throughout this mini-course, we will trace the origins of the accountability movement, the increased role of the federal government, the design of accountability interventions, and the impact of accountability programs on student performance.
This mini-course contains five lectures, with most lectures divided into three videos. The mini-courses also include assigned readings, discussion forums, and assessments.
This is the third mini-course in a four-course sequence.
- Mini-Course 1: History and Politics of U.S. Education
- Mini-Course 2: Teacher Policies
- Mini-Course 3: Accountability and National Standards
- Mini-Course 4: School Choice

This is a real Caltech class. It will be taught concurrently to Caltech and on-line students. This has two implications. On the costs side: the class is challenging, makes extensive use of calculus, and will demand significant effort. On the benefit side: successful completion of the class will provide you with an in-depth understanding of basic economics, and will permanently change the way you see the world.
The history of postwar Tokyo reveals an essential feature of the modern city, i.e. the city as a place of visualities. In postwar Tokyo, countless gazes fell upon others; gazes from and upon Americans and the Emperor, gazes going up skyscrapers or rushing aggressively through the cityscape, and gazes twining and wriggling among classes, genders, and ethnic groups in downtown Tokyo. In Part 2, we will focus on the geopolitics of these gazes in modern Tokyo. What kinds of gazes fell upon the war orphans, the poor, and the marginalized groups in Tokyo? How did students themselves, who represented the vast accumulation of knowledge in Tokyo, perform in front of these gazes? Moreover, how did cinema or television shows, as media for these gazes, implicate the whole city? In answering these questions, we will identify the geopolitics historically involved in the practice of “visualizing postwar Tokyo.”
Being an entrepreneur and creating a startup requires money. This money is essential to building a prototype, hiring a great team, and launching a new product or service. How do you raise money for your startup? Venture capitalists.

This interdisciplinary course explores the complex interactions between poverty, rural livelihoods, and forest resources in developing countries. We will consider some of the dynamics that occur when impoverished people use forests in their daily lives. We will talk about the role of forests for medicines and wild foods, as sources of fuelwood and charcoal for energy, and other pressing topics that confront sustainable forest management such as the impacts of human health and diseases on forests. The course consists of modules on forests and livelihoods in developing countries, agroforestry, human health in forested environments, protected areas and their sustainability, small and medium forest enterprises (SMFEs), and community forestry. Three cross-cutting themes (gender, tenure and forest rights, and climate change) will span all of the modules.
This course will engage you in developing a deeper understanding of the fundamental importance of forest resources in the lives and livelihoods of people in developing countries. Participants from tropical and developing countries may have lived much of what we will talk about in this course, and your experiences will deepen our understanding of the course material. Participants not from a developing country will gain a much better appreciation for the multitude of ways that people in developing countries use forest resources. Weekly videos will be complemented by readings, quizzes, and links to online resources to help you explore current scholarship in this domain. A discussion forum will enable you to delve more deeply into these issues with other participants and the course staff. The themes covered in this MOOC are important to anyone working in international forestry.
This module, the third installment of the multi-part Poetry in America series, focuses on the poetry of Walt Whitman, a quintessentially American writer whose work continues to bear heavily upon the American poetic tradition. We will explore Whitman’s relationship to the City, the Self, and the Body through his life and poetry. Distinguished guests in this module include Tour de France champion Greg LeMond, Supreme Court Justice Elena Kagan, and Whitman scholar Karen Karbiener.
Led by Harvard Professor Elisa New, Poetry in America surveys nearly 400 years of American poetry. Through video lectures, archival images and texts, expeditions to historic sites, interpretive seminars with large and small groups, interviews with poets and scholars, and conversations about poems with distinguished Americans, Poetry in America embarks on a journey through the literature of a nation. Distinguished guests, including President Bill Clinton, Elena Kagan, Henry Louis Gates, Eve Ensler, John McCain, Andrea Mitchell, Michael Pollan, Drew Faust, Tony Kushner, and Nas, among others, bring fresh perspectives to the study of American Poetry.

Learn about contracts from Harvard Law Professor Charles Fried, one of the world’s leading authorities on contract law. Contracts are promises that the law will enforce. But when will the law refuse to honor a promise? What happens when one party does not hold to their part of the deal? This version of the course adds new units on Interpretation, Agency, Partnerships, Corporations, and Government Regulation.
We are exposed to contracts in all areas of our life — agreeing to terms when downloading a new computer program, hiring a contractor to repair a leaking roof, and even ordering a meal at a restaurant. Knowing the principles of contracts is not just a skill needed by lawyers, it illuminates for everyone a crucial institution that we use all the time and generally take for granted.
This contract law course, with new materials and updated case examples, is designed to introduce the range of issues that arise when entering and enforcing contracts. It will provide an introduction to what a contract is and also analyze the purpose and significance of contracts. Then, it will discuss the intent to create legal relations, legality and morality, and the distinction between gifts and bargains. The course also investigates common pitfalls: one-sided promises, mistake, fraud, and frustration. With the knowledge of what makes contracts and how they can go wrong, Professor Fried will discuss remedies and specific performance. Finally, Professor Fried will introduce how contracts can create rights for third parties.
The course’s instructor, Charles Fried, has been teaching at Harvard Law School for more than 50 years and has written extensively on contracts. Not only is Professor Fried a leading authority on contract law, but he also utilizes a story-telling approach to explaining the topic, which creates a unique and interesting class experience.
