Cultural Geography of the World is one of the most popular undergraduate courses at Peking University. It is an inclusive, general introductory course, combining natural and cultural geography with history and art. Through the lens of humanism and independent thinking, learners will be encouraged to observe and analyze cultural phenomena from spatial and time perspectives. This course has 12 chapters: The basic research method of world cultural geography; The division of world culture areas; The world's population distribution and migration of population; Origin of agriculture; Diffusion and regional differences; The origin and spread of the city; Regional differences and characteristics of urban morphology; The spatial distribution of the major languages, religions, ethnicities in the world and their relationship; The great geographical discovery and the formation of the world colonial system; World geopolitics and the spatial structures of the world geography system; Global economic integration; Urbanization and its political, economic, social impacts. Using relevant domestic and foreign textbooks, publications, maps, photos, and charts to show the difference and the changing progress of spatial patterns of the cultures, learners will be asked to observe and analyze cultural phenomena with geographic and spatial vision and to consider the development and changing process of the cultural phenomena in light of time sequence. The course will include a midterm and final exam.

The course is one of the PKU-DeTao MOOCs, which is a joint effort by Peking University and DeTao Masters Academy.

In this course we will explore the challenges faced by investigators when trying to piece together the probable sequence of events. We will familiarize you with the investigative ways of thinking and forming of conclusions. In fact, you’ll learn to think and act as an air safety investigator.

Thought-provoking assignments test your observation skills, fact-finding skills and analytical skills. The assignments give you a taste of what investigators face during an investigation. Skills such as Inductive and Deductive reasoning are highlighted to explain the challenging process of air safety investigation. This professional course contains assignments, individual feedback and live online sessions.

Air safety investigations are complex and affect people from all over the world, with different backgrounds. This course is aimed at different target groups so you can experience different perspectives. We will focus on the legal framework behind air safety investigations world-wide, and the generic procedures followed when an aviation occurrence happens.

Generalist track & Expert track

As this course is for a broad group of professional learners, you have the opportunity to select assignments according to your specific professional needs. After enrolment you will receive access to the generalist track. If you are up for the challenge, we offer the expert track at no additional cost.

Safety professionals with years of relevant experience will thus have the opportunity to work on an in-depth, challenging case. This case is also open to others, if they are willing to commit their time.

The CEU certificate will specify the track type and its learning objectives.

Would this be a course for me?

This is the right course for you, if you are:

• A professional working in aviation (such as pilots, engineering and safety staff, ground staff etc.) seeking for a more fundamental understanding of the process behind air safety investigations.
• A safety professional interested in safety within Aviation.
• A professional working in fields who deal with the outcomes of aviation incidents and accidents such as journalists, lawyers, psychologists.
• Anyone who is interested in this field.

This aerodynamics course focuses on the study of the flow of air about a body, and the “body” will be an airplane, but many of the concepts explored are relevant to a wide variety of applications from sailboats to automobiles to birds. Learners completing this aerodynamics course will gain a fundamental understanding of concepts and models used to aerodynamically analyze and design subsonic, transonic, and supersonic aircraft.

While the course is an introduction to aerodynamics, it is an advanced subject typically taken as a third or fourth year undergraduate subject in aerospace engineering.

Alguna vez te preguntaste: ¿por qué se hinchan los pies después de una boda?, ¿Cuánta agua hay que beber al día?, ¿cuánta agua es demasiada?, ¿Por qué beber agua era una forma de tortura en la edad media?, ¿Cómo terminar un maratón sin deshidratarte?, ¿Por qué los médicos pueden llegar a prescribir dietas pobres en frutas y verduras?, ¿Debes tomar suplementos de fósforo para la memoria?, ¿Cómo retrasar el envejecimiento?, y, sobre todo…  ¿por qué murió el campeón del concurso de bebedores de cerveza?

Este curso es una introducción a la fisiología (funcionamiento normal) y patología (enfermedades) de los riñones: Comenzando con los mecanismos que mantienen el equilibrio del agua, de la sal, del potasio, del fósforo, de la vitamina D, de la eritropoietina (si, esa, ¡la EPO de los escándalos del deporte!) y, sobre todo, de la hormona antienvejecimiento Klotho, el curso te permitirá conocer mejor el funcionamiento de los riñones y aplicar estos conocimientos a tu vida cotidiana.

We live on the surface of a dynamic and yet paradoxically stable planet that experiences a remarkable range of energetic phenomena, from waves and currents in the ocean to wind and thunderstorms in the atmosphere. This course traces how the remarkable concept called energy is the natural way of describing, understanding and unifying these diverse phenomena. The course traces the cascade of energy from sunlight to its final destination in a thermal form, considering differential surface heating, the role of convection and buoyancy and the formation of the Earth’s circulation system, and the links to the ocean circulation system. We consider the curvature and rotation of the Earth as key constraints on a system driven by sunlight and energy transformations.

How much time will the course take?

Obviously the answer will depend on your background and motivation to master the course material. Each week will consist of 5 or 6 segments that will each take 5 to 10 minutes to watch or listen to once. There will be some exploratory questions for each lesson and a confirmation quiz for each week. There will be one exploratory activity for each week. The average commitment will be 2-3 hours per week with perhaps 20 hours required for the whole course.

What background does the course assume?

We’ll ask you to pull out a calculator from time to time (but not all the time!) simply as this will help you really master the key ideas. The key thing is to have a curiosity and interest in what makes our planet tick!

What kind of learning activities will the course involve?

The activities are designed to use basic household objects, and our own senses, to engage with observations of the world, and to think about what these mean and lead to. We’ll get you to sense how cold or warm different objects get when left in the sun, and to observe how energy explains things we see and hear.

What difference will the course make to my life?

The course has the conviction that it is hard to care for or value things that we don’t appreciate or have never considered. Although harsh in certain places and times, the Earth’s surface is remarkably habitable. Many forms of life can make their way in many kinds of terrain and climate. What produces these conditions? How are they maintained? We will seek to answer those questions in rudimentary form at least.

What conversations will the course help to perform?

Courses often imagine a context in which the course material is discussed, and this one is no different. It imagines a setting with family or friends where you might have just learned of a news event involving a storm like a hurricane or thunderstorm, or where a community might have experienced a flood or a drought, or merely unusual weather. You might have heard of El Nino or climate change in the news. This course will give you a background to better engage in a conversation about these great matters, and offer a better sense of the complexity, challenge and wonder connected to living on the surface of such an energetic planet.

This course introduces you to the main elements of a good “science of delivery” case study and teaches you how to plan your research, conduct interviews, and organize your writing.    

The “science of delivery” begins with a simple observation. We often have a vision of the right policies or strategies for improving health, safety, and economic well being, but the real problem is getting things done. Even a simple policy intervention such as child vaccination requires much more than nurses and a stock of vaccine to be effective.

Case studies are a vital tool for sharing insight about the how of policy implementation and institutional reform. They trace the steps taken to produce results, show solutions people have devised to address anticipated challenges and overcome unanticipated obstacles. Case studies help us think about how to adapt approaches so that they work in different contexts.

This social science course is most suitable for:

• Practitioners who want to document and analyze their efforts to implement a program or build a new institution
• Researchers who want to trace how programs achieved results
• Graduate students who want an introduction to one type of case study method

No certificates, statements of accomplishment, or other credentials will be awarded in connection with this course.

The purpose of this course is to introduce students to the major social variables—social class, race, gender, poverty, income distribution, social networks/support, community cohesion, the work and neighborhood environment—that affect population health.

The course covers the theoretical underpinnings of each construct (e.g. "race" as a social category), and surveys the empirical research linking each to population health status. Methods are introduced to operationalize each construct for the purposes of empirical application in epidemiologic research.

The study of the night sky instilled wonder in our ancestors. Modern astronomy extends the human view to previously unexplored regions of space and time. In this course, you will gain an understanding of these discoveries through a focus on relativity—Einstein's fascinating and non-intuitive description of the physical world. By studying relativity and astronomy together, you will develop physical insight and quantitative skills, and you’ll regain a profound sense of wonder for the universe we call home.

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.

A wondrously romantic belief is that brilliant thinkers magically produce brilliant ideas: Einstein jostles his hair and relativity falls out. We can enjoy these fanciful visions of leaps of genius, but we should not be fooled into believing that they’re reality.

Brilliant innovators are brilliant because they practice habits of thinking that inevitably carry them step by step to works of genius. No magic and no leaps are involved.

Professor Starbird will discuss how habits of effective thinking and creativity can be taught and learned through puzzles and mathematics. Anyone who practices these habits of mind will inevitably create new insights, new ideas, and new solutions.

We are surrounded by information, much of it numerical, and it is important to know how to make sense of it. Stat2x is an introduction to the fundamental concepts and methods of statistics, the science of drawing conclusions from data.

The course is the online equivalent of Statistics 2, a 15-week introductory course taken in Berkeley by about 1,000 students each year. Stat2x is divided into three 5-week components. Stat2.1x is the first of the three.

The focus of Stat2.1x is on descriptive statistics. The goal of descriptive statistics is to summarize and present numerical information in a manner that is illuminating and useful. The course will cover graphical as well as numerical summaries of data, starting with a single variable and progressing to the relation between two variables. Methods will be illustrated with data from a variety of areas in the sciences and humanities.

There will be no mindless memorization of formulas and methods. Throughout Stat2.1x, the emphasis will be on understanding the reasoning behind the calculations, the assumptions under which they are valid, and the correct interpretation of results.
