History, Captured in the River Fleet Sewer

History is hard sometimes, when all you have are dates and events to remember. It helps to have context. Montessori schools build a lot of history and social science on the concept of the needs of people. While the need for electronics excites many of my students, another fundamental need is for sanitation.

RJ Evans has a wonderful post, full of excellent photography that will go a long way toward capturing the imagination, which encapsulates the history of London by looking at the evolution of the River Fleet – from a “clear and sparkling” stream in medieval times, to a chartered, elegant, underground sewer system built by excellent, Victorian engineers that still functions today.

Everything is in place, thanks to the ingenuity of the Victorian engineers, to ensure that the Fleet is confined to these tunnels. Yet it was not always like that. If we travel back a few centuries we find a different story altogether – one which is not without its own pathos if such an emotion can be felt for a river.

Match Stick Rockets

A great, simple, and slightly dangerous way of making rockets. There are a number of variations. I like NASA’s because they have a very nice set of instructions.

With a stable launch platform that maintains consistent but changeable launch angles, these could be a great source of simple science experiments that look at the physics of ballistics and the math of parabolas (a nice video camera would be a great help here too) and statistics (matchsticks aren’t exactly precision instruments).

The Spirit of the Law

A You are the Ref strip by Paul Trevillion.

Every week, artist Paul Trevillon poses, in text and cartoon form, some truly idiosyncratic situations that might come up in a soccer match in his You are the Ref strip on the Guardian website. Readers get a week to propose their solutions and then referee Keith Hackett give his official answers.

It’s a fascinating series, the subtext of which is that, while there is a lot of minutiae to remember – the actual diameter of a soccer ball is important for one question – the game official is really out there to enforce the spirit of the laws, enabling fair and fluid play to the best of their ability. This is a useful lesson for adolescents who tend toward being extremely literal, and have to work on their abstract thinking skills, especially when they relate to questions of justice. For this reason, I find that when refereeing their games it’s useful to take the time during the game, and afterward in our post-match discussions, to talk about the more controversial calls.

Cyberwar

Perhaps it’s cultural conditioning, or maybe it’s genetic a predisposition, but adolescent boys to seem to have more of a predilection for war games than their female peers. The games they like tend to be first-person-shooters, like Call of Duty, and, given the trends toward improved video game graphics and remote, kinetic military action, real and simulated life seem to be converging.

Recently however, the Stuxnet virus exposed a much less glamorous picture of the future of cyber warfare. Kim Zetter has an excellent, extensive article in Wired on the computer scientists and engineers who reverse engineered the virus to try to figure out who made it and what it did. Since the virus seems to have been aimed at damaging Iran’s nuclear enrichment plants their work brought them to the edge of the world of international espionage. And they still don’t really know who created this remarkably sophisticated virus, though they suspect the U.S. and Israel.

One of the most interesting take-home messages from Zetter’s article is the amazing degree of international collaboration it took to figure things out. The virus was discovered by someone in Belarus. Researchers from the anti-virus company Symantec’s offices in California, Tokyo and Paris worked together passing information from one office to the next to keep the project going 24 hours a day. They published their findings to share them, and when they ran into stumbling blocks they couldn’t solve they put out calls for help on the internet – and people responded, bringing in expertise from Germany and the Netherlands.

The virus’ secretive creators and the open, diverse collaborators who untangled the virus reflect two conflicting aspects of the future that computer technology and the internet are making possible. And this conflict is showing up more and more in different areas – take Wikileaks for example – so it will be very interesting to see where the future takes us. Of course, we are not simply flotsam on the tides of history. As citizens of the internet, we have been enabled. We have a certain power, and a concomitant responsibility, to shape what we have for the benefit of our fellow citizens and those that come after us.

Molly Backes on How to Be a Writer

Molly Backes, an author of young adult fiction, considers the question from a mother about her teenager, “She wants to be a writer. What should we be doing?”

Her first answer was, “You really do have to write a lot. I mean, that’s mostly it. You write a lot.”

But then she thought about it, and that’s where it gets really interesting:

First of all, let her be bored. …

Let her be lonely. Let her believe that no one in the world truly understands her. …

Let her have secrets. …

…

Let her fail. Let her write pages and pages of painful poetry and terrible prose. …

Let her make mistakes.

…

Let her find her own voice, even if she has to try on the voices of a hundred others first to do so. …

Keep her safe but not too safe, comfortable but not too comfortable, happy but not too happy.

Above all else, love and support her. …

— Bakes (2011): How to Be a Writer

At the end she posts a picture of her collection of forty-two writer’s notebooks.

It’s a wonderfully written and well considered post that I’d recommend to anyone trying to teach writing and language, particularly if you take the apprentice writer approach. And, I’ve always been a great believer in the power of boredom.

Backes’ advice more-or-less summarizes my interpretation of the Montessori approach: create a safe environment and give students the opportunity to explore and learn, even if it means a certain amount of struggle and failure.

Jungle play area at the Skudeneshavn Primary School in Karmøy on the west coast of Norway is another great example of creating an environment that offers students the opportunity to explore.

It’s also interesting to note how differently writers and other experts think, yet how much their practices overlap. Mathematician Kevin Houston also recommends writing a lot when he explains how to think like a mathematician, but his objective is to use full, rigorous sentences to clarify hard logic, and less to explore the beauty of the language or discover something profound about shared humanity.

The Future of Stuff

The Story of Stuff is a pretty commonly used video that starts the conversation on resource use and consumerism. The video below, “Full Printed,” takes a look at the future and how technology, particularly 3-D printers, might reduce the environmental costs of the things we use.

Update

There are already some places for 3d printing.
