Volcanic eruptions are a powerful demonstration of the energy of the Earth´s interior. A materials-based understanding of the evolution of erupting systems provides a quantitative physico-chemical description of the nature of lava and magma and the role of experiments in quantifying the eruptive process.

In this course, students will iterate on a single project starting with sketches, user personas, and outlines. Through the process of user testing and iteration, students will create a highly refined and well-designed virtual reality experience—starting with low-fidelity content and continually improving it based on information from real users. Through the lens of a single application using Unity, user testing, and mobile VR, students will learn about things such as simulator sickness, movement mechanics, audio, user focus, and the overall design process. Once a student has completed the VR Design course, they are ready to create a well-designed VR experience from inception to final product.

After taking this course, you should be able to identify the pros & cons of the VR headsets currently on the market, identify future technologies that will increase the immersiveness of VR, and give examples of ways VR will impact certain industries, such as Education or Medicine. Throughout the course, you will be exposed to key concepts that are used in the VR industry such as Lightfield Displays or Foveated Rendering. You will also get a chance to prototype some of these concepts in the Unity Game Engine. At the end of each lesson, you will write a blog post, where you will design a VR applications for the headset of your choice using the concepts we have covered.

In this course, you’ll learn the the fundamentals of using the Unity Game Engine to build beautiful and performant VR scenes. Starting from basic game objects, you will learn about transforms and materials, so that you can position objects and make them look realistic. Next, you will experiment with animations and cameras in order to make our scenes more engaging in VR. And finally, you will add some complex lighting to your scene to really make your experience really stand out.

This course is designed to teach you how to make your VR experience more dynamic and responsive to your users. You will be exposed to C# programming and using it in the Unity interface. Upon completing this course,, you will have learned basic programming constructs such as methods, loops, variables, and using events and how to apply them in a VR environment.

Writing in the wake of the Civil War, poet Walt Whitman insisted that "the real war will never get in the books." Throughout American history, the experience of war has fundamentally shaped the ways that Americans think about themselves, their fellow Americans, and the meanings of national citizenship. War has also posed challenges of representation, both for those who fought as well as those who did not. This subject examines how Americans have told the stories of modern war in history, literature, and popular culture, and interprets them in terms of changing ideas about American national identity.

Over thirty years ago, confident in the superiority of American military power, the United States set out to "fix" the Greater Middle East. Since that time, U.S. troops, covert operatives and proxies have engaged in costly exertions in predominantly Muslim societies everywhere from the Levant and the Persian Gulf to East Africa and Central Asia. With what result? Washington's efforts have exacted a terrible toll, squandering vast amounts of blood and treasure. In the meantime, the Islamic world has become less stable while anti-American radicalism flourishes. America’s War for the Greater Middle East has failed, and that failure is irreversible.

This course offers a history of that war, for better understanding of the factors that inspired the United States to launch the conflict and to persist in a doomed enterprise. Inviting you to learn how the war unfolded from one phase to the next, from the era of Jimmy Carter to the age of Barack Obama, it catalogs the errors of judgment and implementation made along the way. Finally, it encourages you to consider alternative approaches to policy that might have better served the interests of the United States and of the people living in countries invaded, occupied, bombed and otherwise subjected to American punishment.  

Review the history, archaeology, art, and literature of ancient Egypt relating to warfare and weapons from the Predynastic Period to the end of the New Kingdom (Dynasty 20), evaluating the evidence represented by these source materials. The content includes; Kings, enemies, soldiers and weapons, Warfare in the Old and Middle Kingdoms, Warfare in the 18th Dynasty, Warfare in the Ramesside Period.

An introduction to the life and work of Andy Warhol, one of the world’s most famous artists, through exploration of five thematic framings of his life and career: celebrity, sex, money, death and time.

This course is a general overview of the recent political science literature on violent non-state actors. Its aim is to examine why non-state actors (such as warlords, terrorists, militias, etc.) resort to violence, what means and tactics they use, and what can be done to counter that violence. In that regard, the class will cover works pertaining to the production side of non-state violence (i.e. the objectives and organization of insurgents/terrorists/militias/warlords, their mobilization strategies and support base, how they coerce opponents, etc.); as well as the response that violence elicits from governments or other actors (i.e. counter-insurgency or counter-terrorism strategies, among others). Apart from introducing the basic variables and theoretical and empirical findings in the literature, this course will also grapple with questions of definition, operationalization of variables, and general methodology relevant to conducting research in this area of violent conflict. Though thematically-driven, this course will also reference cases from the contemporary battlefields of insurgency and terrorism (be it Afghanistan, Iraq, Pakistan, the West Bank and Gaza, Colombia, etc.) as they relate to the pertinent themes.

Alexander the Great conquered most of the world known to the ancient Greeks, fused the eastern and western peoples of his empire, and became a god – before his 33rd birthday. This course explores the life, leadership, and legacies of history’s warrior, and one of its most controversial leaders, an ambiguous genius whose story helps us to understand not only the history of warfare, but also different ideas about human sexuality, the history of relations between east and west, and the religious beliefs both of ancient polytheists and modern monotheists.

This course deals with the principles of infrastructure planning in developing countries, with a focus on appropriate and sustainable technologies for water and sanitation. It also incorporates technical, socio-cultural, public health, and economic factors into the planning and design of water and sanitation systems. Upon completion, students will be able to plan simple, yet reliable, water supply and sanitation systems for developing countries that are compatible with local customs and available human and material resources. Graduate and upper division students from any department who are interested in international development at the grassroots level are encouraged to participate in this interdisciplinary subject.

Acknowledgment

This course was jointly developed by Earthea Nance and Susan Murcott in Spring 2006.

This course examines the policy and planning for the provision of water supply and sanitation services in developing countries. It reviews available technologies, but emphasizes the planning and policy process, including economic, social, environmental, and health issues. The course incorporates considerations of financing, pricing, institutional structure, consumer demand, and community participation in the planning process. And it evaluates policies and projects in case studies from Asia, Africa, Latin America, and Central and Eastern Europe.
