18.098 Street-Fighting Mathematics (MIT)
This course teaches the art of guessing results and solving problems without doing a proof or an exact calculation. Techniques include extreme-cases reasoning, dimensional analysis, successive approximation, discretization, generalization, and pictorial analysis. Applications include mental calculation, solid geometry, musical intervals, logarithms, integration, infinite series, solitaire, and differential equations. (No epsilons or deltas are harmed by taking this course.) This course is offere
The Strongest Material Known to Man
Graphene is in incredibly strong, one-molecule thick layer of carbon atoms that could someday be used to create life-sustaining nanorobots. The promise is that in the coming decades with carbon nanotubes, with graphene, we’ll create even new substances which can replace the silicon of computers, maybe even give us a space elevator. Graphene for example, is a substance made out of one-molecule-thick layer of carbon. Think about that. (02:11)
Legislative and Presidential Politics
Democracy entails a complicated process of dynamic interactions between diverse actors pursuing often-conflicting interests. Politics in a democratic system is thus naturally messy, complicated, and confusing. This is exemplified most clearly by the two national institutions, i.e., legislature and the Presidency.
Introducing Royal Research Ship Discovery
This week in the Planet Earth Podcast: Richard Sanders from the National Oceanography Centre and Captain of the Royal Research Ship Discovery, Antonio Gatti, describe the new 100-metre-long vessel's next-generation scientific capabilities.
Interview with Professor Christoph von Fürer-Haimendorf
Professor Christoph von Fürer-Haimendorf was one of the grandfathers of Himalayan anthropology. Alan Macfarlane, one of his last PhD students at the School of Oriental and African Studies and now himself Professor of Anthropological Science at the Univesity of Cambridge, interviewed Christoph von Fürer-Haimendorf in his house in Lode, near Cambridge, in June 1983. The interview was filmed on Sony U-Matic, a large format video tape, which is now obsolete but which has been digitised to DVCam, a

1.017 Computing and Data Analysis for Environmental Applications (MIT)
This subject is a computer-oriented introduction to probability and data analysis. It is designed to give students the knowledge and practical experience they need to interpret lab and field data. Basic probability concepts are introduced at the outset because they provide a systematic way to describe uncertainty. They form the basis for the analysis of quantitative data in science and engineering. The MATLAB® programming language is used to perform virtual experiments and to analyze real-wo
Cynergies: Technologies that Hybridize Physical and Cyberspaces
This paper presents ways in which cybrids depend for their technology upon three existing models of architectural hybrid: display space, environmental computing, and augmented/mixed reality. Cybrids bring these techniques together into a synergistic whole that depends as much on the observer for its consistency as it does on its comprising technologies. This synergy is a product of corroborative behavior between different modes, which provide cybrid users with a coherent social/spatial experienc
How to Fix the Housing Crisis The foreclosure crisis has crawled on for going on four years now with no end in sight. The S&P/Case-Shiller index for August fell 3.8 percent from a year ago. The index includes home prices for 20 US cities. "Continued house price declines could lead to even more defaults, foreclosures and distress sales, undermining wealth, confidence and spending," Willia

The Perfect Machine
The author takes a semi-serious look at the world of computers, robots and androids in an attempt to find a recipe for the perfect machine. Described in this article are the possible attributes of the perfect machine and some of the problems it might raise
Turnstijl Houses & Cannoli Framing
This work presumes that integrating modeling tools and digital fabrication technology into architectural practice will transform how we build the detached house. Single-family houses come in all shapes and sizes, and in doing so, imply variation as well in certain materials, methods, and lighter classes of structure. Ultimately, houses are extensions, if not expressions, of those dwelling within, yet our attempts to produce appealing manufactured houses have prioritized standardization over var
This three minute video shows several temples and art and examines the Golden Age of Greece. This is a travel video with historical insights given. A good video to help students understand the achievements of Greece and look at the very places students usually learn about while studying this time period and the Greek pursuit of perfection.

"Kafka Comes to America: Fighting for Justice in the War on Terror" (video)
"Our government can make you disappear." Those were the words Steven Wax never imagined he would hear himself say. In his twenty-nine years as a public defender, Wax had never had to warn a client that he or she might be taken away to a military brig, or worse, a "black site", one of our country's dreaded secret prisons. How had our country come to this? The disappearance of people happens in places ruled by t

Quarter 4, Lesson 12 - Graphing Rational Functions
In this lesson we learn how to graph Rational Functions. We learn how to use the Vertical and Horizontal Asymptotes to draw the hyperbolas that represent variations from the Parent Rational Function.
