Variations on a Theme

102. Hipsters - Rotterdam 2008 from Exactitudes.

In seeking their identity, adolescents try out a wide variety of different personas. These are often closely associated with changing appearance and style. What I find interesting is how the different styles increasingly cross cultures and other traditional divides (like race). This is evident in Ari Versluis and Ellie Uyttenbroek’s photographic series Exactitudes.

There’s something sad about the loss of local cultural uniqueness to globalization; it’s a bit similar to the feeling you get when you hear about another interesting species becoming extinct. Curiously, however, when Versluis and Uyttenbroek tile together photographs of different people from the same subculture striking identical poses, they not only highlight the similarities between very different people, but also the minute variations that individuals employs to make the subgroup’s “uniform” their own.

26. Preppies - Rotterdam 1999 (from Exactitudes). Girls, "... at Montessori school."

All 128 pictures sets are thought provoking and worth a look. I think they would make useful subjects for students to reflect on (though, warning, there is a little nudity in one of the sets).

Call of Duty Poem

I encourage my students to write what they know.

Bullets flying past my face,
After the enemy like a chase.
Grenades landing right beside me,
I’ve now deployed my RC-XD.
Staying camouflaged on my hands and knees,
LOOKOUT, SNIPERS IN THE TREES!

A silenced weapon keeps me stealthy,
Kill the enemy, with my Valkyrie.
Dolphin dive onto the ground,
My magazine is almost out of rounds.
I get shot with a pistol,
In the back of the head.
My teammate tries to revive me,
But it’s too late, I’m already dead.

Salt and Sugar Under the Microscope

Sugar crystals under 40x magnification.

Salt and sugar crystals have wonderfully distinctive crystal forms. They might well be good subjects for introducing minerals, crystals and some of the more complex geometric solids.

Cube shaped salt crystals under 40x magnification.

The salt crystals are clearly cubic, even though some of the grains seem to be made up of overlapping cubes.

The atoms that make up salt's atomic lattice are arranged in a cubic shape, which results in the shape of the salt crystals. The smaller grey atoms are sodium (Na), and the larger green ones are chlorine (Cl).

Salt is an ionic compound, made of sodium and chloride atoms (NaCl). When a number of these molecules get together to form a crystal, they tend to arrange themselves in a cubic pattern. As a result, the salt crystals are also cubic. In fact, if you break a salt crystal, it will tend to break along the planes that are at the surfaces of the planes of the atomic lattice to create a nice, shiny crystal faces. Gem cutters use this fact to great effect when they shape diamonds and other precious stones.

Of course different crystals have different atomic arrangements. The difference is clear when you compare salt to sugar.

A single sugar crystal looks a bit like a fallen column.

Sugar crystals look a bit like hexagonal pillars that have fallen over. According to the Beet-sugar handbook (Asadi, 2007), sugar crystals actually have a monoclinic form, which could end up as asymmetric hexagonal pillars. Salt crystals, on the other hand, have the habit of forming cubes.

And Women Inherit the Internet

Women are the routers and amplifiers of the social web. And they are the rocket fuel of ecommerce.

–Aileen Lee (2011): Why Women Rule The Internet on TechCrunch.com.

Last month I observed that the girls in my class were blogging a lot more than the boys. It’s still true, and now there’s an informative, if somewhat hyperbolic, article by Aileen Lee that asserts that the blooming of social media websites is driven, primarily, by women.

I’m always a bit leery about articles like this one. There are lots of statistics, a few anecdotes, and a brief reference back to some scientific research (Dunbar numbers), but the overly excited language coming from a venture capitalist is enough to remind me of the irrational exuberance of the dot-com bubble.

The writing is so over-the-top, that I’m truly surprised that there isn’t a single exclamation point in the entire article! Although, based on Ms. Lee’s first words in the comments section, this might be due to the herculean efforts of a good editor.

My antipathy might also be due to my irrational, visceral distaste of the language of business and commerce, which is so geared toward breaking people into faceless demographic groups to be marketed to that it verges on being dehumanizing. I suspect my feelings are truly irrational because I’ve seen scientists do similar parsing of demographic statistics and have had no trouble; although, perhaps, I may have been a little more empathic because the scientists were looking at issues of vulnerability to disease, infant mortality, and the like.

However, since the article’s anecdotes correlate with my own anecdotes, I find it hard to disagree with the underlying premise: women are more inclined than men to make and nurture social connections so they are a key demographic in understanding the future of the internet.

It’s also a reminder that the social atomization typified by the dominance of the nuclear family at the expense of extended family, is now being ameliorated by social networking, which suggests some interesting social and cultural changes in a, possibly, more matrifocal future.

Looking for the beat

Engine room,
It could never die, never,
Because it is nine months my mother make me check out she heartbeat.

—David Rudder (1988): from Engine Room

Despite those nine months, scientists have identified a condition called beat deafness, where people just can’t find the beat.

The article claims it’s rare. My wife tells me it must be genetic.
