How can Iran be stopped from getting a nuclear bomb—negotiations, sanctions, or military action? As a participant in this course, you will advise the president in deciding whether, and how, the U.S. should act. Once you’ve made your assessment, you will move on to wrestle with other scenarios preoccupying policy makers. Between the Assad regime and ISIS, civilians in Syria and Iraq face unimaginable atrocities. Should the U.S. intervene? China’s rise is rattling capitalist economies and a half-century of Pacific peace. What counterbalancing actions should Washington take? Leaks are a fact of life — but why do they happen? Who gets them, and why? Should journalists publish or withhold them? Does legal accountability lie with the leaker—or the journalist?

This six-week course casts you as advisors on the hardest decisions any president has to make. We will go behind the veil to see the dynamic between the press and the U.S. government, to explore these dilemmas. We will also have to contend with the reality that government secrets rarely stay that way. Participants will learn to navigate the political landscape of an era in which private remarks become viral tweets, and mistakes by intelligence agencies become front-page stories.

Weekly assignments require strategic thinking: Analyzing dynamics of challenges and developing strategies for addressing them.  Students will learn to summarize their analyses in a succinct “Strategic Options Memo,” combining careful analysis and strategic imagination with the necessity to communicate to major constituencies in order to sustain public support. They will also examine how policymaking is affected by constant, public analysis of government deliberations.

Learn about one of the greatest engineering efforts in human history: NASA’s Project Apollo and the space race to put a man on the moon.

Apollo 11 landed on the moon in 1969, just eleven years after the first successful satellite launch (Sputnik in 1957) and forty-three years after Robert Goddard’s launch of the world’s first liquid fueled rocket. But the history of rocket development actually can be traced back more than 2,000 years to the experiments of Archytas, an ancient Greek Philosopher.

This aerospace history course will take you back in time and trace the many developments in technology that transformed rockets from celebratory accouterments to weapons and finally to launchpads for human space travel. It is a story of technology, but ultimately the emphasis on this course is about people. Some are very well-known, but others not so.

You will learn how the Chinese introduced rockets as weapons, how early experimenters succeeded through trial and error, how scientific advancement provided the foundation for rocket development and space travel, and how rocket use spread throughout the world prior to the modern era. Finally, you will be introduced to the contributions of rocket pioneers such as Tsiolkovsky, Oberth and Goddard who dreamed of and paved the way for space travel. The course culminates with an introduction of German rocket development in the early 1930s and the emergence the genius rocket engineer Wehner von Braun.

In 2011, a magnitude 9.0 earthquake triggered a major tsunami that devastated northeast Japan, killing more than 15,000 people and crippling a nuclear power plant.

Natural disasters like this one can be seen throughout our Earth’s history. They will continue to prey on all regions, bringing devastation when they strike. But are we so powerless? What if we could improve preparedness over the world and limit the devastation caused by coastal disasters?

These are the questions we at Waseda University have been asking. Now we would like to share our experiences and achievements in disaster prevention with the rest of the world.

In this environmental studies course, you will learn about coastal disasters. Using worldwide field surveys, you will develop an understanding of the nature of tsunamis and storm surges. You will learn how coastal areas are attacked, understand how human lives are lost and infrastructure destroyed. Using numerical simulations and hydraulic experiments, we will present you with different scenarios, teaching you about the mechanisms behind a coastal disaster.

You will look at successful coastal disaster prevention concepts and methods. This will include defenses such as coastal dikes, as well as the implementation of essential evacuation plans. Ultimately, you will learn how to reduce the effects of coastal disasters and how to protect yourself and others if a disaster strikes.

Whether you are an emergency management official, a city developer, an engineering student, or living in a potential natural coastal disaster community, this environmental studies course will teach you how we can improve disaster preparedness and management throughout the world.

Description de ce cours : Chaque région du monde présente des facteurs de vulnérabilité au changement climatique mais est néanmoins en mesure d’atténuer les effets de ce phénomène et de renforcer sa résilience. En ratifiant l’Accord de Paris, la communauté internationale a manifesté sa volonté d’agir. En effet, sans action climatique concertée, les progrès accomplis pendant des décennies en matière de développement seront menacés : nous nous trouvons donc à un moment décisif. Ce cours présente les données scientifiques les plus récentes sur la question, explique les différentes répercussions ressenties au plan régional, décrit les stratégies d’action climatique et mentionne différents types d’action qui s’offrent à vous.

Le cours « Bassions la Chaleur: de la science à l’action climatique » se déroule sur quatre semaines. Les deux premières seront consacrées à un tour d’horizon complet des données scientifiques disponibles sur le changement climatique, puis à la description des effets du réchauffement propres à certaines régions au XXIe siècle. Les deux dernières semaines seront axées sur les stratégies d’action que divers pays et régions mettent en œuvre pour relever le défi climatique ainsi que sur la manière dont chacun d’entre nous peut agir.

Format du cours

Ce MOOC est conçu selon un rythme hebdomadaire : il prévoit les ressources, les activités et les exercices qui vous sont destinés durant chacune des quatre semaines du cours. Chaque semaine, divers matériels pédagogiques seront mis à votre disposition :

• Des forums de discussion et des échanges sur les médias sociaux pour collaborer avec d’autres habitants de la planète, tout en enrichissant l’interaction entre les participants
• Une séance de questions-réponses interactive en direct avec des spécialistes internationaux du changement climatique sur l’application Google Hangout
• Enfin, votre projet final consistera en un document numérique.

One of the key components when you plan and deploy Microsoft Windows Server is storage. Most organizations require lots of storage because users and applications are constantly working with and creating data.

As a Microsoft Windows Server System Administrator you must be able to:  

• Identify and decide on the type of storage your organization needs
• Manage disks, volumes, and file systems
• Use BitLocker to secure volumes
• Encrypt data with Encrypted File System (EFS)

This interactive computer science course teaches through video, discussion, practical exercises and assessments. Each topic is job- focused and designed to ensure you can confidently perform the task.

This course can help you:

• Decide if a career in IT is for you
• Prepare for an introductory job in Windows Server administration
• Study for Microsoft certification tests and badges
• Improve your skills in handling disks and volumes, and securing Windows Server storage

Students taking this course will also be interested in INF201.22, Optimizing Windows Server Storage. INF201.22 builds on the foundational knowledge gained in this course.

Optimizing Microsoft Windows Server storage is key to keeping pace with your organization’s ever increasing data needs. Once you have initially configured your Microsoft Windows Server storage you will want to take advantage of three key features: iSCSI Storage, Storage Spaces and Data Deduplication.

iSCSI is a protocol that supports remote access to SCSI-based storage devices over a TCP/IP network. It provides and easy to use alternative to Storage Area Networks (SANs) and can use existing infrastructure.

Storage Spaces lets you group physical disks together and present them as a single logical disk. This makes it easy to manage and dynamically allocate storage.

Data Deduplication is a service that identifies and removes duplications within data. The goal of Data Deduplication is to maximize the use of disk space.

This course follows INF201.21, Implementing Microsoft Windows Server Disks and Volumes but it is not required.

Go beyond simple storage strategies and take control of your organization’s storage needs!

Prime numbers are one of the most important subjects in mathematics. Many mathematicians from ancient times to the 21st century have studied prime numbers.

In this math course, you will learn the definition and basic properties of prime numbers, and how they obey mysterious laws. Some prime numbers were discovered several hundred years ago whereas others have only been proven recently. Even today, many mathematicians are trying to discover new laws of prime numbers.

Calculating by a pen and paper, you will explore the mysterious world of prime numbers. Join us as we tackle math problems, and work together to discover new laws on prime numbers. Let's study and have fun!

Have you ever wanted to change the world? Have you ever wondered what motivates some people to become activists? What experiences in your childhood or when you were a teenager may have shaped your political identity? Join us, along with Gloria Steinem, Loretta Ross, and others, in a seven-week exploration of these questions and more. In this course, you will analyze some of the psychological theories that help explain what leads people to want to change society.

Through rich, interactive case studies you will meet nine prominent women activists who were engaged in efforts and movements in the U.S. from the 1960s through the 1990s including the Civil Rights Movement, the LGBTQ Movement, and the Reproductive Justice Movement. Within our online community you will discuss and debate how psychological theories can explain these activists’ motivations, discover where the theories are and are not applicable, and collaboratively create new understandings and analyses.

Each week, Gloria Steinem (SC ‘56) will provide her thoughts and insight into how these theories might apply to contemporary issues.
