Silk

How to make silk using the traditional method, by the American Museum of Natural History.

I’ve loved Barry Hughart’s novel, “Bridge of Brids” from the first time I read it a number of years ago. It is the story of a peasant boy, Number Ten Ox, who, with the assistance of the drunken sage Master Li, has to save the children of his village by unraveling the mystery of the powerful Duke of Chin. Not only is it beautifully written, with a poetic story arc and engaging characters, but it also has a wonderful description of initial stages of the silk making process, even though the book describes itself as, “A novel of an ancient China that never was.” The descriptions of Chinese traditions are accurate and detailed enough that you learn a lot about the country. Pulling apart what is historically accurate and what is fiction makes and interesting challenge but is not too difficult.

The universe … for scale

The American Natural History Museum has a YouTube channel with some interesting science-related videos. The one above, “shows the known universe as mapped through astronomical observations.”

Every satellite, moon, planet, star and galaxy is represented to scale and in its correct, measured location according to the best scientific research to-date.

Food fight

Although we eschew warfare as a means resolving differences, this video, which “is an abridged history of American-centric war, from World War II to present day, told through the foods of the countries in conflict”, provides a fascinating perspective on the world. It comes from the Food Fight website.

The key to the different food characters will probably be useful for those less familiar with American history. Watching it without the key might also be useful if you’re interested in discussing metaphors, which should become extremely obvious when you get to the World Trade Centers.

I’m really curious too see how the mini-demographic groups respond to this video. I can predict that some of the more video game (FPS) infatuated students will love this. But how will my more food oriented students react?

The future of SketchUp

Google’s SketchUp software is a great way to work on, and test, higher level geometry skills. This video is a well made, poignant introduction to what software like SketchUp could one day become. It has excellent story development, and has produced a great response from my students.

Free documentaries online

The website http://www.freedocumentaries.org/ has a large number of political documentaries available for free download. Although they seem to be mostly from the perspective of the left (and some seem to come from quite far to the left), there are a number of interesting titles dealing with human rights and the media. A few titles pop out (that I’ve heard are good but have not yet seen myself):
