A Few of My Unpublished 9/11 Pictures

ny-2-36-f800 — Lower Manhatten on the evening of 9/11 2001.

I was sorting through my slide collection, while preparing for our recent move, and came across my binder of slides from New York on 9/11. These are actual, physical slides, organized neatly in plastic binder pages, not digital images.

If I remember correctly, I was just visiting the city that day, staying with my grandparents in Brooklyn. The visit was for work, I’d a post-doc lined up at Columbia and I’d lived in the city before, so I’d not thought to bring my camera with me.

So I walked into Manhattan, against the crowds turned out by the silent subways. Edging against the flux of humanity walking across the bridges away from the tragedy.

And I bought a camera, on the afternoon of September 11th, in a small shop somewhere around 32nd Street. The proprietor was sitting behind the glass cases, following what was going on outside on a small television set. Fortunately, the electricity and credit card system were still working. He was happy to sell me a good, used, fully manual Pentax K1000 (just like the one I’d left at home), and enough slide film to get me through the day.

I’ve always had faith in the strength and resiliency of New York. It’s where I’d spent my first four years, as an impressionable teenager, after immigrating to the U.S., but I would not have been able to harbor any doubts about those first, likely naive, impressions after that day. And this was without seeing or even knowing about the heroics at the World Trade Center. All I could see was the calm and matter-of-factness of the people on the street. Though the arteries had clogged, the blood of the city, its people, still flowed.

Nor was I the only one headed towards the dense clouds of smoke, made eerily attractive by the clear sunlight and pellucid skies of that clear September day. I don’t think I would have made it over the bridge if there were not a few other people, hugging against the railing, edging their way across. That infinitesimal trickle turned into a small but steady stream on the streets of Manhattan itself, which was then dammed up by the police line at Canal Street. Being unable to see anything from there, I turned left and joined the crowd this time as took me back across the Manhattan Bridge back into Brooklyn.

I figured the opposite waterfront would be the best place of any for me to get any glimpse of what was going on. So, once across, I looped under the eastern side of the bridge and walked along the roads that edge the shore until I ended up in Brooklyn Bridge Park.

The picture at the top of the post is from the Brooklyn Bridge Park. I managed to get two major icons into the frame that are important personal symbols: a piece of the Brooklyn Bridge is on the right edge and, if you squint, you can see the Statue of Liberty (my favorite landmark) on the left. They’re a good reminder of the history and purpose of this great city. I also like that the picture captures the silhouette of the city dove, a graceful symbol of peace, standing against the roiling clouds of smoke, dust and turmoil.

Adolescents Versus Their Brains

The part of the brain responsible for logic and reasoning is slow to develop compared to the rest during our adolescence. As a result, adolescents are driven way too much by their emotions and instincts. This means that a lot of the time someone else, teachers and parents usually, have to provide that rationality for them, and help them develop those thinking skills for themselves.

That, at least, was my take-home message after reading David Walsh’s excellent book Why Do They Act That Way. He does an excellent job explaining how the brain develops during adolescence, how it affects the way teenagers behave, and some of the best approaches to dealing with it.

There are a lot of excellent details about how brain development interacts with hormones to create many of the behaviors we find typical of teenagers. Since puberty proceeds differently for girls and boys, Walsh also highlights the differences in the timing of development, and the contrasting results of the different hormones released.

Yet, he also recognizes that adolescent behavior is not solely the result of biology. The effects of neurological and hormonal changes are amplified in industrial societies where kids spend less time with parents, and more time with peers, than in non-WIERD cultures (see The Myth of Adolescent Angst) which leads into his approach to dealing with teens.

To address this unfortunate combination of nature and culture, Walsh advocates a structured approach to parenting, where rules are clear, reasonable, and enforced. This, however, needs to be balanced with the need to keep lines of communication open, which is not an easy trick. Teenagers will want to push you away, but it’s necessary to keep connected to them anyway.

He also emphasizes the need for mentoring good behavior and rational thinking, because, as we’ve seen before, while the developing pre-frontal cortex provides the capacity for formal thinking, it needs practice and training to work well. And, after all, two of the key things we ultimately look for in adults are self-control and the ability to think rationally.

This book is an extremely useful read for parents and teachers (though the first chapter is a bit slow for the impatient). It does a great job of explaining how biology affects behavior, and how to deal with them. I particularly like fact that Walsh has found that teens find it useful to know all this biology stuff too, and it affects how they behave.

Guide to Using a Microscope

Sitting innocuously on the clearance table at a Barnes & Noble (in Cedar Rapid, Iowa actually) was a copy of Georg Stehli’s The Microscope and How to Use It.

At 75% off it was less than $3, which is quite a steal for a guide to what I found to be the most fascinating piece of scientific equipment for my middle schoolers. One of their first natural world lessons was on how to use the microscope. In the classroom there was always one sitting on the shelf, protected by its translucent plastic cover, but easily accessible.

I also took one everywhere, including to the cabins on our immersion trips, which is where they discovered the crystalline structure of salt and sugar grains, and the microfossils at Coon Creek.

And, interestingly enough, my microscopy posts are some of the most popular posts on this blog (the onion cell is regularly in the top ten).

The Microscope and how to use it by Georg Stehli.

Apart from the basics of how to use a microscope, Stehli’s book goes into simple sample preparations and preservation for almost everything you’re likely to encounter in the curriculum, in the classroom, and in the back yard. Though neither crystal structure nor microfossils are covered, the techniques for looking a the hard parts of biological specimens are applicable.

I would have loved to have had a copy of this last year when I was trying to figure out which were the best dyes to use for some of the odder samples my students came up with, and how to make them into permanent slides. It’s not easy to find this kind of broad reference online.

Serialized Canticle

The science fiction classic,A Canticle for Leibowitz, is available in the public domain as an adapted audio serial from Old Time Radio via the Internet Archive.

Inspired by the author’s participation in the Allied bombing of the monastery at Monte Cassino during World War II, the novel is considered a masterpiece by literary critics. It has been compared favorably with the works of Evelyn Waugh, Graham Greene, and Walker Percy, and its themes of religion, recurrence, and church versus state have generated a significant body of scholarly research.

Build Your Own Solar System: An Interactive Model

National Geographic has a cute little game that lets you create a two-dimensional solar system, with a sun and some planets, and then simulates the gravitational forces that make them orbit and collide with each other. The pictures are pretty, but I prefer the VPython model of the solar system forming from the nebula.

The models starts off with a cloud of interstellar bodies which are drawn together by gravitational attraction. Every time they collide they merge creating bigger and bigger bodies: the largest of which becomes the sun near the center of the simulation, while the smaller bodies orbit like the planets.

This model also comes out of Sherwood and Chabay’s Physics text, but I’ve adapted it to make it a little more interactives. You can tag along for a ride with one of the orbiting planets, which, since this is 3d, makes for an excellent perspective (see the video). You can also switch the trails on and off so you can see the paths of the planetary bodies, note their orbits and see the deviations from their ideal ellipses that result from the gravitational pull of the other planets.

I’ve found this model to be a great way to introduce topics like the formation of the solar system, gravity, and even climate history (the ice ages over the last 2 million years were largely impelled by changes in the ellipticity of the Earth’s orbit).

Mapping Internet Space

Internet-map-700x700 — A map of the internet from the Opte Project.

The Opte Project has produced a number of excellent maps of the internet. There is a profound beauty in the immensity of the interconnections that’s reminiscent of the suffusion of stars that can be seen in Milky Way on a dark night on an isolated beach. Unfortunately, their website seems to have not been updated since 2005.
