The Architectural Imagination | HarvardX on edX | Course About Video
 
02:05
Learn fundamental principles of architecture — as an academic subject or a professional career — from a study of history’s important buildings. Take this course free on edX: https://www.edx.org/course/architectural-imagination-harvardx-gsd1x#! ABOUT THIS COURSE Architecture engages a culture’s deepest social values and expresses them in material, aesthetic form. In this course, you will learn how to “read” architecture as a cultural expression as well as a technical achievement. Vivid analyses of exemplary buildings from a wide range of historical contexts, coupled with hands-on exercises in drawing and modeling, bring you close to the work of an actual architect or historian. Architecture is one of the most complexly negotiated and globally recognized cultural practices, both as an academic subject and a professional career. Its production involves all of the technical, aesthetic, political, and economic issues at play within a given society. Over the course of ten modules, we’ll examine some of history’s most important examples that show how architecture engages, mediates, and expresses a culture’s complex aspirations. The first part of the course introduces the idea of the architectural imagination as a faculty that mediates sensuous experience and conceptual understanding. Two examples of the architectural imagination—perspective drawing and architectural typology—are explored through video presentations and hands-on exercises. You will be introduced to some of the challenges involved in writing architectural history, revealing that architecture does not always have a straightforward relationship to its own history. In the second set of modules, we address technology as a component of architecture’s realization and understanding. Architecture is embedded in contexts where technologies and materials of construction—glass and steel, reinforced concrete—are crucial agents of change. But a society’s technology does not determine its architectural forms. You will discover ways that innovative technology can enable and promote new aesthetic experiences, or disrupt age-old traditions. You will witness architecture’s ways of converting brute technical means into meaningful perceptions and textures of daily life. The interactions of architecture and modern technologies changed not only what could be built, but also what kinds of constructions could even be thought of as architecture. The final set of modules confronts architecture’s complex relationship to its social and historical contexts and its audiences, achievements, and aspirations. As a professional practice deeply embedded in society, architecture has social obligations and the aesthetic power to negotiate social change; to carry collective memories; even to express society’s utopian ideals. You will learn about what we call architecture’s power of representation, and see how architecture has a particular capacity to produce collective meaning and memories. WHAT YOU'LL LEARN How to read, analyze, and understand different forms of architectural representation Social and historical contexts behind major works of architecture Basic principles to produce your own architectural drawings and models Pertinent content for academic study or a professional career as an architect

Introduction to Control System Design - A First Look | MITx on edX | Course About Video
 
02:21
Learn the theory and practice of controller design by building and then position-stabilizing a propeller-levitated arm. Take this course free on edX: https://www.edx.org/course/introduction-control-system-design-first-mitx-6-302-0x#! ABOUT THIS COURSE Have you wondered about the design strategies behind temperature controllers, quad-copters, or self-balancing scooters? Are you interested in robotics, and have heard of, or tried, “line-following" or “PID control” and want to understand more? Feedback control is a remarkably pervasive engineering principle. Feedback control uses sensor data (e.g. brightness, temperature, or velocity) to adjust or correct actuation (e.g. steering angle, motor acceleration, or heater output), and you use it all the time, like when you steer a bicycle, catch a ball, or stand upright. But even though applications of feedback are very common, the subject is an uncommonly compelling example of mathematical theory guiding practical design. In this engineering course we will introduce you to the theory and practice of feedback control and provide a glimpse into this rich and beautiful subject. Each week we will begin with a mathematical description of a fundamental feedback concept, combined with on-line exercises to test your understanding, and will finish with you designing, implementing, measuring, and analyzing a hardware system, that you build, for controlling a propeller-levitated-arm feedback system. You will not need a background in calculus or software engineering to succeed in this class but you should be familiar with algebra and mechanical forces, have some exposure to complex numbers, and be comfortable with modifying mathematical formulas in short computer programs. This is a lab course, and in order to complete the weekly assignments, you will need to purchase/acquire a list of parts. To make sure you receive your parts before the class begins, you should register promptly, so that you can access the lists of parts and international vendors. WHAT YOU'LL LEARN - How to set up a control system and understand and optimize its performance (the Arduino-controlled propeller-levitated arm) - Modeling Feedback Control systems Using Difference Equations - What unstable systems are like, practically and mathematically - How to measure control system performance - How proportional, delta (aka derivative) and summation (aka integral) feedback reduce tracking errors and increase disturbance rejection

Contracts are a part of our everyday life, arising in collaboration, trust, promise and credit. How are contracts formed? What makes a contract enforceable? What happens when one party breaks a promise? Take this course free on edX: https://www.edx.org/course/contract-law-trust-promise-contract-harvardx-hls2x-0 ABOUT THIS COURSE Learn about contracts from Harvard Law Professor Charles Fried, one of the world’s leading authorities on contract law. Contracts are promises that the law will enforce. But when will the law refuse to honor a promise? What happens when one party does not hold to their part of the deal? We are exposed to contracts in all areas of our life — agreeing to terms when downloading a new computer program, hiring a contractor to repair a leaking roof, and even ordering a meal at a restaurant. Knowing the principles of contracts is not just a skill needed by lawyers, it illuminates for everyone a crucial institution that we use all the time and generally take for granted. This contract law course, with new materials and updated case examples, is designed to introduce the range of issues that arise when entering and enforcing contracts. It will provide an introduction to what a contract is and also analyze the purpose and significance of contracts. Then, it will discuss the intent to create legal relations, legality and morality, and the distinction between gifts and bargains. The course also investigates common pitfalls: one-sided promises, mistake, fraud, and frustration. With the knowledge of what makes contracts and how they can go wrong, Professor Fried will discuss remedies and specific performance. Finally, Professor Fried will introduce how contracts can create rights for third parties. The course’s instructor, Charles Fried, has been teaching at Harvard Law School for more than 50 years and has written extensively on contracts. Not only is Professor Fried a leading authority on contract law, but he also utilizes a story-telling approach to explaining the topic, which creates a unique and interesting class experience. WHAT YOU'LL LEARN - A theoretical background of contracts, trust, and promise - Contracts the government will stand behind and those it won’t - Illusory promises, offer and acceptance - The limitations of contract law - Writing and Interpretation of contracts - Key concepts including mistake, fraud, and frustration; remedies and specific performance; and third parties

ABOUT THIS COURSE Bioethics provides an overview of the legal, medical, and ethical questions around reproduction and human genetics and how to apply legal reasoning to these questions. This law course includes interviews with individuals who have used surrogacy and sperm donation, with medical professionals who are experts in current reproductive technologies like In Vitro Fertilization and Preimplantation Genetic Diagnosis, and bioethicists and journalists who study the ownership and use of genetic information within human tissue. Additional Harvard colleagues will also share with you their thoughts on topics such as disability law as it relates to reproductive technology. While the law and ethics surrounding these technologies are a central component to this course, we also show you examples of the deeply personal and human side of these issues. Throughout the course, and with the help of law students, we will discuss leading legal cases in this field, which will illuminate the types of questions the law has struggled with – stretching and evolving over time. From the famous Baby M surrogacy case, to cases on the paternity of sperm donors, to a case related to the ownership of human tissue turned into a commercial product, and others. We will show you the ethical, legal, and rhetorical underpinnings, which have served as the basis for various court decisions over the past 20 or 30 years. We will also explore potential future technologies and their implications for society: genetic enhancements to increase our intelligence, let us live a hundred years longer, or make us immune to diseases – and the possibility of creating animal-human hybrids, for example a mouse with a humanized brain. The content within this course is intended to be instructive, and show how legal reasoning has been applied, or could be applied, to questions related to parenthood, reproduction, and other issues surrounding human genetic material. The material organized within this course should be considered an authoritative overview, but is not intended to serve as medical or legal advice. This course is designed for a diverse audience including, but not limited to, law students, prospective law students, medical professionals, as well as members of the general public interested in questions and topics related to surrogacy, parenthood, genetic and reproductive technology, ownership of genetic material, and more.

A Global History of Architecture — Part 1 | MITx on edX | Course About Video
 
03:09
A Global History of Architecture — Part 1 This course is a history of architecture from a global perspective. About this Course How do we understand architecture? One way of answering this question is by looking through the lens of history. This course will examine architecture through time, beginning with First Societies and extending to the 15th century. Though the course is chronological, it is not intended as a linear narrative, but rather aims to provide a more global view, by focusing on different architectural "moments." The lectures will give students the appropriate grounding for understanding a range of buildings and contexts. The material in the lectures will be supplemented by readings from the textbook A Global History of Architecture. Each lecture analyzes a particular architectural transformation arising from a dynamic cultural situation. How did the introduction of iron in the ninth century BCE impact regional politics and the development of architecture? How did new religious formations, such as Buddhism and Hinduism, produce new architectural understandings? What were the architectural consequences of the changing political landscape in northern Italy in the 14th century? How did rock-cut architecture move across space and time from West Asia to India to Africa? How did the emergence of corn impact the rise of religious and temple construction in Mexico? These are typical questions that the lectures will address. All required readings are available within the courseware, courtesy of Wiley. Print or electronic versions of the A Global History of Architecture, Second Edition and Architecture of First Societies are also available for purchase. The course is aimed for a general audience at the undergraduate level with an interest in history. All lectures will be in English.

Intro to Probability - The Science of Uncertainty | MITx on edX | About Video
 
02:05
Introduction to Probability - The Science of Uncertainty An introduction to probabilistic models, including random processes and the basic elements of statistical inference. Register for Introduction to Probability from MIT at http://edx.org/courses. About this Course The world is full of uncertainty: accidents, storms, unruly financial markets, noisy communications. The world is also full of data. Probabilistic modeling and the related field of statistical inference are the keys to analyzing data and making scientifically sound predictions. Probabilistic models use the language of mathematics. But instead of relying on the traditional "theorem - proof" format, we develop the material in an intuitive -- but still rigorous and mathematically precise -- manner. Furthermore, while the applications are multiple and evident, we emphasize the basic concepts and methodologies that are universally applicable. The course covers all of the basic probability concepts, including: - multiple discrete or continuous random variables, expectations, and conditional distributions - laws of large numbers - the main tools of Bayesian inference methods - an introduction to random processes (Poisson processes and Markov chains) The contents of this course are essentially the same as those of the corresponding MIT class (Probabilistic Systems Analysis and Applied Probability) -- a course that has been offered and continuously refined over more than 50 years. It is a challenging class, but it will enable you to apply the tools of probability theory to real-world applications or your research. Course Staff: John Tsitsiklis John Tsitsiklis is a Professor with the Department of Electrical Engineering and Computer Science, and a member of the National Academy of Engineering. He obtained his PhD from MIT and joined the faculty in 1984. His research focuses on the analysis and control of stochastic systems, including applications in various domains, from computer networks to finance. He has been teaching probability for over 15 years. Patrick Jaillet Patrick Jaillet is a Professor of Electrical Engineering and Computer Science and Co-Director of the MIT Operations Research Center. He obtained his PhD in Operations Research at MIT. His research interests deal with optimization and decision making under uncertainty as applied to transportation and the internet economy. Professor Jaillet's teaching includes subjects such as algorithms, optimization, and probability.

Calculus Applied! | HarvardX on edX
 
02:13
Apply tools of single-variable calculus to create and analyze mathematical models used by real practitioners in social, life, and physical sciences. In this course, we go beyond the calculus textbook, working with practitioners in social, life and physical sciences to understand how calculus and mathematical models play a role in their work. Through a series of case studies, you’ll learn: How standardized test makers use functions to analyze the difficulty of test questions; How economists model interaction of price and demand using rates of change, in a historical case of subway ridership; How an x-ray is different from a CT-scan, and what this has to do with integrals; How biologists use differential equation models to predict when populations will experience dramatic changes, such as extinction or outbreaks; How the Lotka-Volterra predator-prey model was created to answer a biological puzzle; How statisticians use functions to model data, like income distributions, and how integrals measure chance; How Einstein’s Energy Equation, E=mc2 is an approximation to a more complicated equation. With real practitioners as your guide, you’ll explore these situations in a hands-on way: looking at data and graphs, writing equations, doing calculus computations, and making educated guesses and predictions. This course provides a unique supplement to a course in single-variable calculus. Key topics include application of derivatives, integrals and differential equations, mathematical models and parameters. This course is for anyone who has completed or is currently taking a single-variable calculus course (differential and integral), at the high school (AP or IB) or college/university level. You will need to be familiar with the basics of derivatives, integrals, and differential equations, as well as functions involving polynomials, exponentials, and logarithms. This is a course to learn applications of calculus to other fields, and NOT a course to learn the basics of calculus. Whether you’re a student who has just finished an introductory Calculus course or a teacher looking for more authentic examples for your classroom, there is something for you to learn here, and we hope you’ll join us! What you'll learn Authentic examples and case studies of how calculus is applied to problems in other fields How to analyze mathematical models, including variables, constants, and parameters Appreciation for the assumptions and complications that go into modeling real world situations with mathematics

Street-Fighting Math Teaches, as the antidote to rigor mortis, the art of educated guessing and opportunistic problem solving. Register for Street Fighting Math from MIT at http://www.edx.org/courses. About this Course Too much mathematical rigor teaches rigor mortis: the fear of making an unjustified leap even when it lands on a correct result. Instead of paralysis, have courage: Shoot first and ask questions later. Although unwise as public policy, it is a valuable problem-solving philosophy and the theme of this course: how to guess answers without a proof or an exact calculation, in order to develop insight. You will learn this skill by mastering six reasoning tools---dimensional analysis, easy cases, lumping, pictorial reasoning, taking out the big part, and analogy. The applications will include mental calculation, estimating population growth rates, understanding drag without differential equations, singing musical intervals to estimate logarithms, approximating integrals, summing infinite series, and turning differential equations into algebra. Your learning will be supported by regular readings that you discuss with other students, by short tablet videos, by quick problems to help you check your understanding, by weekly homework problems, review and and a final exam. You will work hard, and, by the end of the course, have learned a rough-and-ready approach to using mathematics to understand the world. All required readings are available within the courseware, courtesy of The MIT Press. A print version of the course textbook, Street-Fighting Math, is also available for purchase.

When you complete a verified certificate in this course it will feature original artwork with both Stan Lee’s and Michael Uslan’s signature. About this Course Join the Smithsonian, and comic book industry legend Stan Lee, to explore the history of the comic book and the rise of superheroes. The ancient gods of Egyptian, Greek and Roman myths still exist, but today, they have superpowers, human foibles and secret identities. They come from comic books and graphic novels, and have taken over pop culture on the stage, screen, video games, and animation. From Superman® and Spiderman®, to The Avengers® and The Hulk® and beyond, who are these heroes? And, how have they evolved from folklore and myth, across all cultures and religions? Learn from Smithsonian and industry experts including: Stan Lee, who created the modern superhero template. His early comics featuring Spiderman, Iron Man®, The Hulk, Thor®, and The Avengers led Marvel to success. He continues to reinvent himself to create modern global superheroes and appear in cameos in superhero films and TV, such as Avengers: Age of Ultron. Michael Uslan, executive producer of top grossing, award winning movies, including The Dark Knight series, Lego® Movie, the animated Batman films and Batman® VS Superman. In this course, we explore the following questions: Why did superheroes first arise in 1938 and experience what we refer to as their “Golden Age” during World War II? Why did the superhero genre ebb and flow in popularity over the decades? How have comic books, published weekly since the mid-1930’s, mirrored a changing American society, reflecting our mores, slang, fads, biases and prejudices? Why was the comic book industry nearly shut down in the McCarthy Era of the 1950’s? How did our superheroes become super-villains in the eyes of the government, clergy, educators, and parents of the mid-20th Century? When and how did comic books become acceptable again, and eventually become valid teaching tools in universities and schools? When and how did comic book artwork become accepted as a true American art form as indigenous to this country as jazz? Finally, when and how did comic books become “cool” and the basis for blockbuster movies, hit TV series, top-selling video games, and acclaimed animation, while also impacting fashion and style- and even the moral and ethical codes of children- around the globe?
