The course invites you to examine the interconnectedness of modern life through an exploration of fundamental questions about how our social, economic, and technological worlds are connected. Students will explore game theory, the structure of the Internet, social contagion, the spread of social power and popularity, and information cascades.

This MOOC is based on an interdisciplinary Cornell University course entitled Networks, taught by professors David Easley, Jon Kleinberg, and Éva Tardos. That course was also the basis for the book, Networks, Crowds, and Markets: Reasoning About a Highly Connected World. This course is designed at the introductory undergraduate level without formal prerequisites.

Ce cours est une première introduction à la mécanique des fluides. Nous allons aborder tout d'abord les propriétés physiques des fluides : les états de la matière et la notion de viscosité. Un chapitre sera dédié à la tension de surface et à la capillarité. Nous introduirons ensuite le concept de similitude et l’utilisation des nombres adimensionnels. Nous allons alors considérer la statique des fluides à travers la loi de l'hydrostatique. La dynamique des fluides sera abordée en premier lieu par la cinématique. Ensuite, nous traiterons des équations de bilan avec notamment une application du théorème de conservation de l’énergie cinétique : le théorème de Bernoulli. Dans le dernier, nous montrerons que ce théorème relativement simple permet d’expliquer et de calculer des écoulements tels que ceux observés dans les rivières. Les vidéos du cours seront enrichies de vidéos d’expériences qui illustreront les concepts clés et par des quiz pour tester votre intuition et vos connaissances. Le dernier module vous permettra de piloter à distance une expérience d'hydraulique qui a lieu dans les laboratoires de l'EPFL.

For the first hundreds of years of modern medicine, progress was a process of trial and error, and to be honest, it was often fatal error, such as bloodletting, which killed the first US president George Washington. Where diseases were clearly understood, and where treatments obviously worked on most patients, such as penicillin for pneumonia, there was no need to delve deeper into questions of effectiveness. But for most conditions, the treatment benefits were modest and there was a need for improved ways of telling whether a new intervention was better than the previous standard treatment. And so scientists introduced a testing procedure for new treatments - the randomized controlled trial.

As the cost of developing new treatments grew, it became very important to detect the slightest improvement that could be attributed to the new drug in order to get it licensed and marketed. So the usual randomized trial was answering the following question: does this treatment work (for otherwise well people with just this single disease, with perfect adherence, treated by the best doctors, under idealised conditions)? But most patients have multiple diseases, imperfect adherence, ordinary doctors and non-ideal circumstances. These patients want to know whether a new treatment is likely to reduce important harms for ordinary people like them, receiving usual care. This mismatch meant that most trials were overestimating the real world effectiveness of new interventions.

In this MOOC, we are going to study this mismatch, and see what its effect is on modern medical care. One example of the studies we will discuss is the VIGOR trial. This influential drug trial resulted in the widespread global overuse of this drug, at a cost of wasted billions of dollars. Ironically, this drug, intended to reduce a problem in individuals, ended up causing more of the same problem in the population!

After we understand the consequences of designing the wrong kinds of trials, we will also look at how best to design pragmatic randomized trials, which answer the important questions that ordinary patients and decision makers in the real world most often ask. We will also explore how these can be combined with economic evaluations and qualitative research – to answer important questions about how much these interventions cost, and how they are experienced by the recipients.

Ever wondered about the sacred scriptures that have sustained for millennia one of the oldest and most diverse religions of the world - Hinduism? Want to discover the lessons this history may offer mankind in the 21st century?

This religion course introduces the rich and diverse textual sources from which millions of Hindus have drawn religious inspiration for millennia. The Bhagavad Gita has offered philosophical insights to a number of modern thinkers. This course will introduce important passages from important Hindu sacred texts, their interpretations by moderns and will give you an opportunity to engage with them.

From simulating complex phenomenon on supercomputers to storing the coordinates needed in modern 3D printing, data is a huge and growing part of our world. A major tool to manipulate and study this data is linear algebra. This course is part 1 of a 2-part course.  In this part, we’ll learn basics of matrix algebra with an emphasis on application. This class has a focus on computer graphics while also containing examples in data mining. We’ll learn to make an image transparent, fade from one image to another, and rotate a 3D wireframe model. We’ll also mine data; for example, we will find similar movies that one might enjoy seeing. In the topic of sports ranking, we’ll be ready to participate in March Madness and submit our own mathematically generated brackets to compete against millions of others. The lectures are developed to encourage you to explore and create your own ideas either through your own programming but also with online tools developed for the course. Come to this course ready to investigate your own ideas.

El curso mostrará el carácter actual, y a veces dramático, de las concepciones que desde la filosofía griega han venido siendo denominadas como “idealismo”. Desplegará las grandes cosmovisiones occidentales en base a sus ideas rectoras, operativas en los estadios científico, artístico y sociocultural, haciendo ver cómo la filosofía ha servido de sustrato o conexión de todas estas manifestaciones espirituales, estableciendo una sistemática efectiva, patente en la atmósfera cultural de las épocas-mundo. Cada uno de estos “mundos” (en el sentido de “ordenación global”) está configurado por un conjunto bien trabado de ideas-fuerza, en torno a una Idea fundamental.

El alumno obtendrá una visión general de la cohesión interna y organización de cada una de estas cosmovisiones, respecto a las cuales se pondrá el acento en su presencia activa en los problemas del presente.
