This course offers a quick practical introduction to Swift basics, including types, variables, constants, and functions. It combines syntax exercises with hands-on iOS development in Xcode. By the end of the course students will build their first iOS app, an app that creates and displays song lyrics customized to user input.

In 3.072x: Symmetry, Structure, and Tensor Properties of Materials, you will study the underlying structures of materials and deepen your understanding of the relationship between the properties of materials and their structures. Topics include lattices, point groups, and space groups in both two and three dimensions; the use of symmetry in the tensor representation of crystal properties; and the relationship between crystalline structure and properties, including transport properties, piezoelectricity, and elasticity. Two course projects will allow students to explore their particular interests in greater depth.  

FAQ

Who can register for this course?
Unfortunately, learners from Iran, 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.

This course covers the derivation of symmetry theory; lattices, point groups, space groups, and their properties; use of symmetry in tensor representation of crystal properties, including anisotropy and representation surfaces; and applications to piezoelectricity and elasticity.

This course is a survey of significant orchestral masterworks composed during three centuries. Listening assignments include 34 symphonies and 24 concertos, composed from the 1720s to the 1990s. Class discussion and oral presentations focus on the works in 18 miniature scores; prior score-reading experience is helpful. Each of the three written papers reviews a concert attended during the term. Since this is a participatory subject, each student will give oral presentations concerning composers and their symphonies and/or concertos.

You will become intimately acquainted with the operational principles of neuronal “life-ware” (synapses, neurons and the networks that they form) as well as with recent ideas about how the dynamics of these networks generate the “neuronal code.” As an aperitif we will highlight present brain-excitements and for dessert we will discuss the future of brain research

This course presents a comparison of different proposed architectures for the syntax module of grammar. The subject traces several themes across a wide variety of approaches, with emphasis on testable differences among models. Models discussed include ancient and medieval proposals, structuralism, early generative grammar, generative semantics, government-binding theory/minimalism, LFG, HPSG, TAG, functionalist perspectives and others.

Studies synthesis of polymeric materials, emphasizing interrelationships of chemical pathways, process conditions, and microarchitecture of molecules produced. Chemical pathways include traditional approaches such as anionic polymerization, radical condensation, and ring-opening polymerizations. Other techniques are discussed, including stable free radical polymerizations and atom transfer free radical polymerizations (ARTP), catalytic approaches to well-defined architectures, and polymer functionalization in bulk and at surfaces. Process conditions include bulk, solution, emulsion, suspension, gas phase, and batch vs. continuous fluidized bed. Microarchitecture includes tacticity, molecular-weight distribution, sequence distributions in copolymers, errors in chains such as branches, head-to-head addition, and peroxide incorporation.

This course focuses on general methods and strategies for the synthesis of complex organic molecules. Emphasis is on strategies for stereoselective synthesis, including stereocontrolled synthesis of complex acyclic compounds.

The course is designed for students in the System Design and Management (SDM) program and therefore assumes that you already have a basic knowledge of project management. The objective is to introduce advanced methods and tools of project management in a realistic context such that they can be taken back to the workplace to improve management of development projects. In contrast to traditional courses on the subject we will emphasize scenarios that cannot be fully predicted such as task iterations, unplanned rework, perceived versus actual progress and misalignments between tasks, product architectures and organizations.

This class was also offered in Course 13 (Department of Ocean Engineering) as 13.615J. In 2005, ocean engineering subjects became part of Course 2 (Department of Mechanical Engineering), and the 13.470J designation was retired.

This course covers principles and methods for technical System Architecture. It presents a synthetic view including: the resolution of ambiguity to identify system goals and boundaries; the creative process of mapping form to function; and the analysis of complexity and methods of decomposition and re-integration. Industrial speakers and faculty present examples from various industries. Heuristic and formal methods are presented. Restricted to SDM (System Design and Management) students.

This course studies what makes a good design and how one develops a good design. Students consider how the design of engineered systems (such as hardware, software, materials, and manufacturing systems) differ from the "design" of natural systems such as biological systems; discuss complexity and how one makes use of complexity theory to improve design; and discover how one uses axiomatic design theory (AD theory) in design of many different kinds of engineered systems. Questions are analyzed using Axiomatic Design Theory and Complexity Theory. Case studies are presented including the design of machines, tribological systems, materials, manufacturing systems, and recent inventions. Implications of AD and complexity theories on biological systems discussed.

Logistics and supply chain structures can be found in virtually any system. In this business and management course you will learn not only what makes leading systems competitive but also how to design, or redesign, your own system.

The MOOC is based on a widely popular university course that will give you a working knowledge on supply chain strategy and design that can be applied in your organisation.

Course topics include:

• How to increase ROI (Return on Investment) using logistics
• Logistics trade-offs (service vs cost vs capital)
• The SCOR model for analysis of supply chains
• Sustainability in supply chains (the triple bottom line)
• The Bullwhip effect and how to beat it
• Strategies regarding:
  • Sourcing
  • Warehousing
  • Product range
  • Production
  • Distribution
  • Transportation
  • Etc.
• Concepts like:
  • Quick Response - QR
  • Efficient Consumer Response, ECR
  • Collaborative Planning, Forecasting and Replenishment, CPFR

Many of the topics in the course will be illustrated using real companies and real logistics professionals as logistics is not a theoretical subject – it exists all around us – everywhere.

By the end of this course, you will be able to better describe, understand and ultimately design your own system for your organisation based on existing knowledge in this exciting field.

Regardless of your industry or organisation type, the concepts and methods from this course will help you become a logistics and supply chain professional. You will never look at a hotel breakfast buffet, a loading bay, a warehouse, a factory, an emergency room or even at a fast food restaurant the same way again…

15.874 and 15.871 provide an introduction to system dynamics modeling for the analysis of business policy and strategy. Students learn to visualize a business organization in terms of the structures and policies that create dynamics and regulate performance. The course uses role playing games, simulation models, and management flight simulators to develop principles for the successful management of complex strategies. Special emphasis will be placed on case studies of successful strategies using system dynamics.

15.874 is a full semester course and 15.871 is a half semester course. The two classes meet together and cover the same material for the first half of the term. In the second half of the semester, only 15.874 continues.

System dynamics is such a tool, allowing health practitioners to model and simulate problems ranging from the molecular level to the entire healthcare system and beyond. This introductory course will teach you the fundamental principles of system dynamics as you learn how to use system dynamics software to explore problems relevant to your field of health. Whether you work in molecular biology, clinical medicine, health policy, or any other health-related field, this course will equip you to investigate the effects of time delays, feedback and system structure. You will learn how to interpret the causes of typical system behaviors such as growth, decay and oscillation in terms of the underlying system properties, and to rapidly develop computer-based models and run simulations to gain insight into the problems in your domain.

This course will empower you with a deeper understanding and an enhanced capacity to achieve useful interventions in healthcare.

Continuation of 15.871, emphasizing tools and methods needed to apply systems thinking and simulation modeling successfully in complex real-world settings. Uses simulation models, management flight simulators, and case studies to deepen the conceptual and modeling skills introduced in 15.871. Through models and case studies of successful applications students learn how to use qualitative and quantitative data to formulate and test models, and how to work effectively with senior executives to implement change successfully.

Many books and thousands of papers cover the field of system dynamics. With all of these resources available, it can be difficult to know where to begin. The System Dynamics in Education Project at MIT put together these resources to help people sort through the vast library of books and papers on system dynamics. This course site includes a collection of papers and computer exercises entitled “Road Maps,” as well as a collection of assignments and solutions that were initially part of a guided study to system dynamics.  Note that while the level of the course indicated in the upper right corner of the screen is "Undergraduate / Graduate," the material is suitable for people ranging from K-12 students to chief executives of corporations.

This course is offered to graduates and includes topics such as mathematical models of systems from observations of their behavior; time series, state-space, and input-output models; model structures, parametrization, and identifiability; non-parametric methods; prediction error methods for parameter estimation, convergence, consistency, and asymptotic distribution; relations to maximum likelihood estimation; recursive estimation; relation to Kalman filters; structure determination; order estimation; Akaike criterion; bounded but unknown noise model; and robustness and practical issues.
