AlgTop18: Classification of combinatorial surfaces II
In this lecture we present the traditional proof of the most important theorem in Algebraic Topology: the classification of (two-dimensional) surfaces using a reduction to a normal or standard form. The main idea is to carefully cut and paste the polygons forming the surface in a particular way, creating either a sphere, or a number of crosscaps or handles.
This is the 18th lecture of this beginner's course in Algebraic Topology, given by N J Wildberger of the School of Mathematics and Statisti

21A.110 Anthropological Theory (MIT)
This course introduces students to some of the major social theories and debates that inspire and inform anthropological analysis. Over the course of the semester, we will investigate a range of theoretical propositions concerning such topics as agency, structure, subjectivity, history, social change, power, culture, and the politics of representation. Ultimately, all theories can be read as statements about human beings and the worlds they create and inhabit. We will approach each theoretical p
Perception - The Reality Beyond Matter
This video delves into the philosophical questions of reality whilst quoting several well known philosophers along the way. (20:27)
1.463J The Impact of Globalization on the Built Environment (MIT)
The course is designed to provide a better understanding of the built environment, globalization, the current financial crisis and the impact of these factors on the rapidly changing and evolving international architecture, engineering, construction fields. We will, hopefully, obtain a better understanding of how these forces of globalization and the current financial crisis are having an impact on the built environment and how they will affect firms and your future career opportunities. We will
English Vocabulary-Lesson 4-Idioms About Driving
Vocabulary for the advanced English language learner. Lesson 4 topic: Idioms and sayings about driving-"backseat driver", "road hog", and "running on empty" The narrator demonstrates the idioms, but does not offer much depth. (2:58).
1.3 Vitamin D The main role of vitamin D is to facilitate the uptake of calcium from food, through the lining of the small intestine into the blood. It also controls the deposition of calcium in the bones during growth and maintains adult bone structure. If vitamin D is deficient, with less calcium available, the skeleton fails to develop normally. The most obvious symptom is the bowing of the leg bones in children, producing the condition called rickets (Author(s):

"Ecology, Human Rights, and Large Dam Projects in South Asia"
Kathleen Morrison is Professor, Department of Anthropology; Director, Center for International Studies, The University of Chicago.
There is little doubt that climate change, deforestation, erosion, and the unequal distribution of natural resources around the globe are of pressing importance everywhere, but these problems are perhaps most acute in Asia, home to 64 percent of the world’s population. Much of this population (1 and 1.3 billion, respectively) is concentrated in India and China, tw
Race to Nowhere: Strees and Students Film
Is the amount of daily stress that students deal with becoming too much to handle? This three minute video explains a bit about the demands put on students by standardized testing. Some hints at how to improve the situation are offered. The video is a promotion of Race to Nowhere.
3.5 Journals Journals and articles written by academics or experts are an excellent source of information. Journals are usually published monthly or quarterly, and contain a selection of articles providing details of recent research. Often they will also contain reviews of relevant books. They are usually published more quickly than books, and so are often more up to date. To access content of journals, most publishers require a subscription. There are, however, some journals which you can freely ac

Session 3: Getting students to chose a viable blogging subject/topic - lorem ipsum In this session you will be introduced to ways you can support students in finding a topic to blog about, which is referred to as a niche. Niche blogging is important for: establishing one’s self as an expert in a given field, building an online community, discoverability online and attracting a loyal following.
Purpose/Aim of this session
1.1.1 Desirable properties of a database As you will see, there are many possible choices that can be made during the design and many rules to guide this work. When trying to decide if some choices are better than others, you need to consider the key desirable properties of a database. The table here outlines some of them: Finite Element Analysis 7.2 Types of active galaxy All active galaxies have a compact, energetic nucleus - an AGN. Seyfert galaxies are spiral galaxies with bright, point-like nuclei which vary in brightness. They show excesses at far infrared and other wavelengths, and have strong, broad emission lines. Quasars resemble very distant Seyfert galaxies with very luminous nuclei. They are variable. About 10% are strong radio sources thought to be powered by jets of material mo 2.7.4 Identities are contextual and interactional Different identities assume greater or less importance, and play different roles, in different contexts and settings, and in interactions with different people. Different aspects of people’s identity may come to the fore in the workplace and in the home, for example, while people might emphasise different aspects of themselves to different people (and different people may see different identities when they meet them).

Formula 1 is the ultimate motor sport. It demands the highest level of skill from both drivers and the engineers behind the cars. So what are the secrets of good car design? How are Formula One cars engineered for maximum performance? This album takes a behind the scenes look at Red Bull Racing, a front-runner on the F1 grid. Using thrilling archive and expert testimony, the tracks explore how the techniques of Finite Element Analysis are used to optimize the performance of different elements of
How do you go about designing an aircraft that has no engine? What forces enable a glider to become airborne and quickly reach high altitudes quickly? The tracks in this album look at the aerodynamics of gliders, ask questions relating to the 'Speed to Fly', and explores the consequences of kinetic and potential energy change, providing a useful way of modelling the behaviour of a glider in the air. This material makes up part of the course MST209, Mathematical methods and models.Author(s):
