Fake news is a real problem. From allegations of election fraud to Pizzagate, fake news saturates our newsfeeds-- and our national discourse. Some say it has compromised the authority of journalism, others say writing fake news stories has brought them a fistful of money. What do we make of this phenomenon? Why is fake news so prevalent these days? And how should we respond?

In this 2-week course, we’ll pose these questions (and more) to scholars, working journalists, and media pundits in order to get a hold on this complicated issue. Join a vibrant community of critical thinkers who are interested in exploring these questions together. Share your experience and see how it compares to others around the world.

This course is part of a broader series from Davidson College, called Davidson Now. We seek to explore critical issues and engage in honest and courageous conversations.

Courses offered via edX.org are not eligible for academic credit from Davidson College. A passing score in a DavidsonX course(s) will only be eligible for a verified certificate generated by edX.org.

Our world is becoming increasingly digitized. For many of us, barely a day goes past without recording a video, taking and editing photos, and sharing digital content across multiple applications. But how well do we understand the technology we're using, and how is digital information created and manipulated?

With many careers today involving some form of computation, there is a growing urgency for individuals to move beyond digital literacy, to understand how digital technologies work, and to develop literacy in code. This course will help you acquire it.

In this course, you will not only learn the inner workings of your digital world, but also create and manipulate images with code, creating new artworks and interactive animations. Your images and animations will be displayed in an online Art Gallery, forming part of a vibrant learning community.

You will also develop effective computational thinking skills and concepts transferable to other coding environments and programming languages.

The most noteworthy startups and entrepreneurs of our day are known for bucking trends in business and leadership.

New ventures often position themselves in a way that forces their more established competitors to react and rethink the fundamentals of their original value proposition. The advantage of these new players often lies in a different management approach compared with large, more established companies.

You can learn to think like these innovators too.

From this course, you’ll better understand the typical process entrepreneurs follow when launching a new venture, thereby helping you to adequately respond to upcoming threats through newly established companies.

You’ll explore an entrepreneur’s perspective in comparison to a manager in a large company; working through the various stages of the entrepreneurial process.You’ll profile the entrepreneur as a personality type, exploring whether an entrepreneurial mindset is something that people inherently possess or something that can be developed over time. You’ll gain insights into the generation of business ideas and how leaders manage to ensure that their ideas also represent a concrete business opportunity with commercial potential.

The course introduces the decision-making process of successful entrepreneurs and specifies how it differs from that of managers in large companies, identifying common patterns. It further introduces the lean start-up process to give you a concrete toolkit applied by successful entrepreneurs and specific pitfalls that typically occur at various stages of the start-up process - to help you avoid similar mistakes.

Besides the online lectures, participants will engage in a series of homework exercises and tutorials. Real-life case studies and examples from companies will be used to help participants better prepare for actual situations.

The idea behind topological systems is simple: if there exists a quantity, which cannot change in an insulating system where all the particles are localized, then the system must become conducting and obtain propagating particles when the quantity (called a "topological invariant") finally changes.

The practical applications of this principle are quite profound, and already within the last eight years they have lead to prediction and discovery of a vast range of new materials with exotic properties that were considered to be impossible before.

What will you gain from this course?

• Learn about the variety of subtopics in topological materials, their relation to each other and to the general principles.
• Learn to follow active research on topology, and critically understand it on your own.
• Acquire skills required to engage in research on your own, and to minimize confusion that often arises even among experienced researchers.

What is the focus of this course?

• Applications of topology in condensed matter based on bulk-edge correspondence.
• Special attention to the most active research topics in topological condensed matter: theory of topological insulators and Majorana fermions, topological classification of "grand ten” symmetry classes, and topological quantum computation
• Extensions of topology to further areas of condensed matter, such as photonic and mechanical systems, topological quantum walks, topology in fractionalized systems, driven or dissipative systems.

What tools does this course use?

• Simple thought experiments that rely on considerations of symmetry or continuity under adiabatic deformations
• Computer simulations similar to those used in actual research will give a more detailed and visual understanding of the involved concepts
• Dissecting research papers that teaches you to simply understand the idea even in the rather involved ones.

This course is a joint effort of Delft University of Technology, QuTech, NanoFront, University of Maryland, and Joint Quantum Institute.

FAQs

Are there any books that are required for the course?

No, the course will only rely on materials and software freely available online.

Is it possible to get credit for this course at my university?

Not by default, but we invite anyone to use the course materials as a basis for a graduate course, with course materials studied as preparation and followed by a classroom discussion. Such courses are planned at universities of Copenhagen, Delft, Leiden, and University of Maryland. Following such a course will obviously give you credit points.

Would it not be better to take a more formal approach, and to describe the math in a more rigorous and systematic way?

While advanced math is certainly relevant for some researchers, in our experience it is the simple things that are the most confusing. We aim for the course to stay accessible and relevant to advanced undergraduate/beginner graduate students, both the theorists and experimentalists.

I do not know enough about condensed matter physics, but I have attended an exciting talk/read a cool article, and I'd like to learn more. Would the course be useful for me?

We are not sure. On the one hand, we will aim the course at people familiar with basic condensed matter physics and the necessary math, hence we will always assume that we don't need to explain e.g. band structures from scratch. However, a good share of the course materials are just discussions which would give you some sort of overview and understanding what this is all about.

Why didn't you discuss my favorite topic, which is certainly relevant and exciting?

Hey, that's a great idea! We aim to start from covering the basic questions, and then let the course evolve together with the field. So if you want, please help us by preparing the materials that would be helpful for the course, and they will become a bonus topic. By the way, same holds if you spot an error, or know how to improve the course: everything about this course is open, so don't hesitate to contribute.

Getting a grip on complex, uncertain multi actor problems.

This course is about the Laplace Transform, a single very powerful tool for understanding the behavior of a wide range of mechanical and electrical systems: from helicopters to skyscrapers, from light bulbs to cell phones. This tool captures the behavior of the system and displays it in highly graphical form that is used every day by engineers to design complex systems.

This course is centered on the concept of the transfer function of a system. Also called the system function, the transfer function completely describes the response of a system to any input signal in a highly conceptual manner. This visualization occurs not in the time domain, where we normally observe behavior of systems, but rather in the “frequency domain.” We need a device for moving from the time domain to the frequency domain; this is the Laplace transform.

We will illustrate these principles using concrete mechanical and electrical systems such as tuned mass dampers and RLC circuits.

We live in a time of disruptive change, one that requires a new collective leadership capacity. In this groundbreaking course, we invite you on a journey to see the world in new ways and practice a method that allows leaders, entire organizations, and larger social systems to connect with and actualize their highest future possibility.

In January 2015, 30,000 people from 190 countries enrolled in U.Lab. In an exit survey, 52% said it was “eye-opening”, while another 36% called it “life-changing”. U.Lab has inspired the first-known use of a MOOC by a government as a platform for citizens to shape the issues that matter to them, it has been used in management teams of the world’s leading NGOs, and it is now being used in 42 Impact Hubs worldwide – by locally-rooted, globally connected communities of change makers to catalyze systemic change.

In the U.Lab you will learn Theory U, an approach to leading profound change that has been developed by action researchers at MIT, and practiced by leaders around the world, for over 20 years.

You will apply this method to a challenge, issue, or system that matters to you.

And you will have the opportunity to form self-organized Hubs and peer coaching circles with other U.Lab participants; in order to co-sense and co-shape the future that you feel is wanting to emerge in your work, and life, right now.

You will be joining a community that includes national government leaders from Scotland, founders and members of 42 Impact Hubs around the world, business leaders in the U.S, Brazil, and China, and many other inspired change makers from over 190 countries worldwide who are interested in creating more aware, inclusive, sustainable societies.

Desde que en 1954 se realizara el primer trasplante exitoso de un órgano, la cirugía de trasplantes se ha desarrollado espectacularmente brindando esperanza y calidad de vida a muchos enfermos. Mientras esas técnicas y posibilidades terapéuticas avanzan, persisten sin embargo muchos interrogantes sobre el modo en el que los órganos pueden obtenerse lícitamente. Algunos de esos dilemas nos acompañan desde siempre, otros son suscitados por la aparición de fenómenos novedosos como el turismo de trasplantes, las posibilidades que ofrece la donación tras la muerte cardiocirculatoria o los descubrimientos sobre las funciones fisiológicas remanentes en los pacientes diagnosticados en muerte cerebral. En la inmensa mayoría de los países no se pueden comprar y vender órganos. ¿Por qué? A pesar de que muchas personas siguen muriendo a la espera de recibir un órgano, en ningún país se confiscan los órganos de las personas fallecidas. ¿Por qué? ¿Pueden donar los menores? ¿Debemos prescindir de la conocida como “regla del donante cadáver” y permitir la eutanasia para la donación? ¿Con qué límites? ¿De qué manera influye la potencial condición de donante de un órgano en los cuidados que se proporcionan al final de la vida? ¿Cómo evitar el conflicto de intereses entre quienes velan por la vida de los futuros receptores de un órgano y quienes aún se afanan por cuidar a quien va a fallecer de manera irremisible e inminente?

En este curso nos adentraremos en el análisis de ésas y otras cuestiones, pero también introduciremos los nuevos desafíos que para la ética y el Derecho plantean trasplantes novedosos así como la discusión en torno a los criterios de justa distribución de los órganos
 
The first successful organ transplantation was performed in 1954. Since then, the technique has evolved tremendously, giving hope and increased quality of life to many patients around the world. While the technology and drugs advance, several controversies persist regarding the way in which organs may be obtained. Some of these dilemmas arose on the very first day in which organs’ transplantation originated; others have emerged as a result of new phenomena such as transplantation tourism, the new possibilities brought by donation after cardio-circulatory death, or increasing knowledge about the remaining physiological functions detected in patients pronounced as brain dead. Almost all countries in the world forbid the selling of organs. Why? Although many people die while on the waiting lists, in no country does the Government confiscate cadaveric organs. Why? May minors be organ donors? Should we abandon the so-called “dead donor rule” and allow “organ-donation euthanasia”? How does the potential condition of becoming a donor influence the administration of end-of-life care? How should we avoid the eventual conflict of interests between those who care for the life of future recipients of organs and those who are in charge of the dying patient-eventual-donor? In this course we will explore the answers to these questions, and we will also engage in the assessment of the more recent challenges posed by novel transplantation techniques, and, albeit briefly, in the discussion regarding the fair distribution of organs.
