The colour is blue at the Aga Khan Museum

The Aga Khan is the head of a small, but wealthy, subset of Shia Islam.

He is known for charitable works around the world. Today's topic is about one of these, the Aga Khan Museum in Toronto. I had decided to visit late last year when I became aware of an exhibit based on trade in West Africa during the Medieval Era. I had been interested in this topic since the company I worked for at the time drew on the history of gold caravans in West Africa for promotional reasons back when it first began working in the area. During field work in different parts of Ghana, we discovered traces of the historical economic development of the region, some of which has been described previously.

I also took a tour of the museum, which detailed many of the architectural details which might otherwise go unappreciated. For instance, the theme of the museum was light, and the dominant colour for the exterior walls was to be white. Normally this would mean marble, but it was rejected because a study had shown that marble broke down too quickly for a building which is meant to last for hundreds of years. Instead, a white granite was located from a quarry in South America

In keeping with the theme of light, most of the interior of the museum is bathed in light from various windows. Elaborate patterned shutters on the windows throw an ever-changing series of patterned shadows across the interior walls of the building as the day proceeds.

Symbology is important in the museum. Apart from the above symbol for nothingess (as everything was created out of nothing, there must be a little bit of "nothing" in everything), there are hexagonal and more complex repeating motifs in the windows and vents, and even the drain in the centre of the courtyard.

Blue seems to be another common theme in the museum. Especially lapis.

The principal symmetry element for the interior is a 1 m x 1 m square. All of the major features in the building line  up with the edge of the squares, or else with 2 m x 2 m squares. All of the double doorways are 2 m across, and the edge of the doorway lines up with the edges of the floor tiles (which are 1 m x 1 m). Even the tiling in the courtyard lines up with the outer edges of 2 m x 2 m squares (the straight segments in the tiles below)

granite as the exterior walls, pink limestone from France, and

Setting up a people for hyperinflation--the Canadian example

The World Complex is not a fan of Stephen Harper and His Government (see here, for instance). But I am forced to conclude that he may be a cannier economist than I originally gave him credit for.

When a country destroys its debts by inflation, it ruins its creditors. The proper progressive approach is to ruin them all equally--thus it is imperative that there be no avenue by which creditors might protect themselves. At the same time, the government wishes no doubt to have its citizens continue to honour its currency, worthless though it might be.

During the Wiemar hyperinflation, despite the frenzied printing, the sum total of foreign currency that could be purchased by all the marks in circulation fell precipitously. There is a Keynesian argument to be made that the Germans didn't print quickly enough! Of course, having Germans individually destroying the currency in great amounts by putting it to such uses as cigarette rolling papers and firewood didn't help either.


It's not always nice to have money to burn.


And consider this--using the currency in lieu of hard-to-locate toilet paper may clog pipes.

Canada recently unveiled polymer bills. Just the perfect cross between plastic and paper money. And the brilliant part is, they are perfect in a hyperinflationary environment.

Plastic. Not really suitable for use as cigarette wrappers or firewood. You wouldn't want to be burning it indoors, anyway.

And as far as toilet paper--although it is a little uncomfortable, the microtexture on the bills does seem to be helpful for cleaning up the really tough spots. And although the bills have not been field-tested for flushability, the beauty of the polymer bills is that you can just wash them and reuse! Or spend, if you prefer.

The only problem the beta testers have reported is that the bills are a little small to be used comfortably.
