Las estructuras están implicadas en nuestras vidas: las plantas, los animales, casi todo lo que fabrica el ser humano, incluso nuestro propio cuerpo, deben soportar una serie de fuerzas sin romperse, y por lo tanto prácticamente cualquier elemento de nuestro entorno es una estructura de una clase u otra.

No cabe duda de que entender cómo se comportan las estructuras es fundamental para entender el mundo que nos rodea, para comprender la naturaleza y para juzgar mejor los progresos que ha hecho la humanidad a lo largo de la historia. Sin embargo, los ingenieros hemos fallado una y otra vez cuando hemos intentado explicar esta materia de forma que los no entendidos puedan entender su importancia.

Este curso pretende saltar esa brecha existente entre los expertos en cálculo de estructuras y los profanos utilizando un lenguaje asequible, empleando ejemplos históricos y proponiendo ensayos sencillos que pueden hacerse en casa. El curso abordará no sólo el problema de por qué los edificios y los puentes se caen sino también otras muchas cuestiones. ¿Por qué las ventanas de los aviones son redondas? ¿Por qué los gusanos tienen esa forma? ¿Por qué los murciélagos pueden volar dentro de un rosal sin rasgarse las alas? ¿Cómo funcionan las arterias? ¿Por qué las catedrales góticas pueden ser tan esbeltas? ¿Por qué hay construcciones romanas que siguen en pie 2000 años después? ¿Qué podemos aprender sobre los constructores de las diferentes estructuras que nos han legado nuestros antepasados?

Muchos contenidos de este curso pueden ser útiles para médicos, biólogos, artistas, historiadores y arqueólogos.

At the end of this course, you will know how to prepare financial statements.

This course focuses on the social, political, economic and institutional environment of countries. This environmental context molds the country’s objectives, defines the country’s strategy, programs and policies for achieving objectives, and significantly impacts companies.

The context is affected by historical events, and by the country’s leadership. Many stakeholders shape the environment and the institutions, or “rules of the game”, that affect business. Labor, students, farmers, non-governmental organizations (NGOs) and the military play a crucial role, making the analysis of country environments complex and fascinating.

We will study Japan in some depth, and catch brief glimpses of South Korea, Singapore, Chile, Turkey, India, South Africa and the former Soviet Union, to appreciate the forces that influence diverse country environments, and companies’ strategies.

The course will review aspects of global institutions, such as the World Trade Organization (WTO), which set global rules that profoundly affect business strategy and human welfare. It will also explore opportunities and challenges at the bottom of the pyramid, the last frontier for value creation by companies and NGOs.

The course topics include modern atomic theory, periodic table and trends, stoichiometry, bonding, molecular structure, kinetics, thermodynamics, equilibrium, acids and bases, gases, liquids and solids, electrochemistry and solubility. This material conveyed using video lectures, practice questions and review exams may be used for self-study by students and teachers. This is a self-paced, asynchronous course. It is meant to be a useful resource without much staff support or involvement. The quizzes and assignments will be auto-graded. While students are welcome to interact with fellow students on the discussion boards, there are no opportunities to interact with the course instructor or staff directly.

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.

Le politique nous concerne tous : chaque jour, des décisions publiques sont adoptées qui impactent notre quotidien. Dans quel contexte ces décisions sont-elles adoptées ? Au 21ème siècle, de nombreux paradoxes brouillent la vision que nous pouvons en avoir. Qu’est-ce que le pouvoir dans la société actuelle ? Quels acteurs en détiennent ? L’État demeure-t-il un acteur politique majeur s’il est concurrencé par des organisations internationales et régionales ? Comment la démocratie prônée par la communauté internationale se différencie-t-elle des régimes autoritaires voire totalitaires ? Quelle est la place des idéologies dans le monde actuel ? Le cours vise à comprendre et à expliquer des phénomènes politiques à partir d’une posture d’analyse critique.

Politics impact all of us: everyday political decisions impact many areas of our lives. In which context are these decisions made? In the 21st century, many paradoxes blur our vision of these decisions. What is power in a multi-level society? Does the state remain the main political actor, if it is in competition with international and regional organizations? Can democracy – pushed forward by the international community – coexist with authoritarian, or even totalitarian, regimes? What is the role of ideologies in contemporary politics? The course aims at understanding and explaining political phenomena from a critical standpoint.

Quel lien existe-t-il entre l’exploitation des ressources naturelles (terre, eau, ressources minières, forêts, ...) et le développement durable ? Ce cours vous permettra de comprendre les opportunités mais aussi les défis que la présence de ressources naturelles offre, tant au niveau local que global. En analysant les effets socio-économiques et écologiques de la ruée actuelle vers ces ressources naturelles, vous comprendrez mieux les liens entre crise agraire, crise alimentaire et crise environnementale. A partir d’études de cas spécifiques, c’est votre regard sur les dynamiques globales contemporaines qui en sera modifié.

A la fin du cours, par rapport à des problématiques liées à la gestion des ressources naturelles (ruée sur la terre, le sous-sol, l’eau et/ou la forêt), vous serez capables de:

• comprendre, comparer et analyser des modèles théoriques qui permettent de décoder de telles problématiques
• décomposer ces problématiques en causes, conséquences, solutions et points de vue divergents sur ces trois elements
• repérer, dans votre environnement, des cas d'étude qui illustrent ces problématiques et leur appliquer le processus de décomposition vu dans le cours.

Vous serez invités à choisir deux ressources naturelles parmi les quatre proposées. Vous développerez les apprentissages annoncés au travers de présentations vidéo par la professeur et par des experts, de QCM, d’un jeu de plateau à jouer avec vos proches (Land Rush), de débats et de cas d’étude proposés par vous, que vous schématiserez et présenterez aux autres via une activité d’évaluation par les pairs.

What kind of link exists between the exploitation of natural resources (land, water, minerals, forests) and sustainable development? This course aims to understand the opportunities and challenges implied by the presence of natural resources at both local and global levels. You will be analyzing the socioeconomic and ecological effects of the contemporary natural resource rush. This will help you to gain a better understanding of the links between land, food and environmental crises. Through the analysis of specific case studies, you’ll look at contemporary global dynamics in a different way.

This mini-course focuses on alternatives to public schools in the United States.

There has been a rapid expansion of school choice in U.S. education. Charter schools now serve over five percent of the public school population, voucher programs have been introduced in many states, and digital education has captured the attention of educators across the country. What is the theoretical basis for these innovations? How effective are the early initiatives? How do parents decide what is best for their children? And how do all of these options affect the students who remain in traditional public schools?

With the help of several scholars and participants in these new ventures, we will discuss the ways in which these school choice initiatives are re-shaping U. S. education.

This mini-course contains five lectures, with most lectures divided into three videos. The mini-courses also includes assigned readings, discussion forums, and assessments.

This is the fourth mini-course in a four-course sequence.

• Mini-Course 1: History and Politics of U.S. Education
• Mini-Course 2: Teacher Policies
• Mini-Course 3: Accountability and National Standards
• Mini-Course 4: School Choice

As modern life science research becomes ever more quantitative, the need for mathematical modeling becomes ever more important. A deeper and mechanistic understanding of complicated biological processes can only come from the understanding of complex interactions at many different scales, for instance, the molecular, the cellular, individual organisms and population levels.

In this course, through case studies, we will examine some simplified and idealized mathematical models and their underlying mathematical framework so that we learn how to construct simplified representations of complex biological processes and phenomena. We will learn how to analyze these models both qualitatively and quantitatively and interpret the results in a biological fashion by providing predictions and hypotheses that experimentalists may verify.

当现代生命科学研究变得更加量化，建立数学模型的需求变得越来越重要。对复杂生物现象的深入理解最终是建立在了解发生于多时空间尺度的复杂生物学相互作用上，例如，分子尺度，细胞尺度，个体和群体尺度上。通过研究一些案例，我们将建立一些简化的数学模型以及其背后的基本数学框架。同时，我们将学习如何建立基本生物学过程的简单表征，以及如何定量和定性和定量地的分析这些模型，并将它们的结果以生物学的方式进行解释，以期提供实验学家进行检验的假说和预测。

This is the second of five modules to introduce concepts and current frontiers of atomic physics and to prepare you for cutting-edge research:

8.421.1x: Resonance

8.421.2x: Atomic structure and atoms in external field

8.421.3x: Atom-Light Interactions 1 -- Matrix elements and quantized field

8.421.4x: Atom-Light interactions 2 --  Line broadening and two-photon transitions

8.421.5x: Coherence

The second module, 8.421.2x, describes atomic structure, including electronic levels, fine structure, hyperfine structure and Lamb shift.  You will then learn about how electric and magnetic fields shift atomic levels. The discussion of time-dependent electric fields prepares you for the interactions of atoms with light and for the dressed atom picture.

At MIT, the content of the five modules makes the first of a two-semester sequence (8.421 and 8.422) for graduate students interested in Atomic, Molecular, and Optical Physics. This sequence is required for Ph.D. students doing research in this field.

In these modules you will learn about the interaction of radiation with atoms: resonance; absorption, stimulated and spontaneous emission; methods of resonance, dressed atom formalism, masers and lasers, cavity quantum electrodynamics; structure of simple atoms, behavior in very strong fields; fundamental tests: time reversal, parity violations, Bell's inequalities; and experimental methods.

Completing the two-course sequence allows you to pursue advanced study and research in cold atoms, as well as specialized topics in condensed matter physics.

FAQ

Who can register for this course?

Unfortunately, learners from Iran, Cuba, Sudan and the Crimea region of Ukraine will not be able to register for this course at the present time. While edX has received a license from the U.S. Office of Foreign Assets Control (OFAC) to offer courses to learners from Iran and Sudan our license does not cover this course.

Separately, EdX has applied for a license to offer courses to learners in the Crimea region of Ukraine, but we are awaiting a determination from OFAC on that application. We are deeply sorry the U.S. government has determined that we have to block these learners, and we are working diligently to rectify this situation as soon as possible.

Learn about the inspirational work of the leading European painters from approximately 1400 to 1800, and explore the issues expressed through the art of painting. Included in this broad time frame are the works of Leonardo da Vinci, Caravaggio, Velázquez, Rembrandt, Vermeer and Goya.

Painters during this period were concerned with ideas such as the pursuit of beauty, the pleasures and pains associated with love, the demonstration of power and status, or the relationship of men and women to the divinity and to nature. In paintings from this period, we find traces of the emergence of the modern mind set, and perspective on issues such as the respective roles of women and men in the world.

This course focuses on images of paintings by the artists listed in the course syllabus. The discussions that will take place in the “course forum” will allow us to touch upon a broader range of issues.

This is the first of five modules to introduce concepts and current frontiers of atomic physics, and to prepare you for cutting-edge research:

Protein is found in virtually every part of your body. At least 10,000 different proteins make you what you are and keep you that way.

In this biology course you will learn how proteins drive almost all living processes.

Proteins manufactured by cells perform a broad range of essential functions — the molecular workforce of living organisms.

You will learn how proteins are the cellular manifestation of genetic information. They are assembled into a polymeric structure from monomers derived in part from components in our diet. Proteins catalyze metabolic reactions, replicate DNA, respond to stimuli, provide movement, and much more. Using video lectures, articles, case studies, and molecular models, we will explore how proteins are constructed, how they fold into 3-dimensional shapes, the kinds of bonds that hold these folded structures together, and the immense range of roles that proteins assume ‑ from structural proteins found in muscle to catalysts for cellular chemical reactions.

Purification and characterization are essential to understand protein structure and function, and we will identify a variety of methods to uncover how these tiny machines drive almost all living processes.
