OxBridge and the future

Wasabi covered peas

The two books I am reading most actively right now both make me miss Oxford. They also make me regret the fact that I am not out traveling or working somewhere exciting.

The first book is Simon Winchester’s The Man Who Loved China: The fantastic story of the eccentric scientist who unlocked the mysteries of the Middle Kingdom. I have read several of his books before: one on the Mercator projection, and another on the genesis of the Oxford English Dictionary. While I am only halfway through this latest book, I think it is better than Mercator but worse than OED, though that probably reflects my own interests as much as anything else. In any case, the book conveys a wonderful sense of what was possible for a motivated and intelligent individual in the position of its protagonist: Noel Joseph Terence Montgomery Needham.

The second book is Oliver Morton’s Eating the Sun: How Plants Power the Planet. Evidently, it is largely a study of the nature and history of photosynthesis. The book contains a good summary of early climatic science, with engaging and informative asides on nuclear physics, biochemistry, and much else. It also includes a great many references to life in Cambridge, during the period between the early outbreak and late aftermath of the second world war. It is a period of unusual interest for climatologists, for reasons I described in my barely-remembered thesis. Personally, my impressions of Cambridge are dominated by the music video to Pink Floyd’s “High Hopes” – one of the very few music videos I have ever watched, and one of the handful I have enjoyed.

What they brought to the forefront is that it is possible to be out and doing interesting things (though certainly more challenging if you mean to do it in a low-carbon way). I would certainly be strongly tempted to strike away from Ottawa to more interesting places, once societal dues have been paid. Where or what that would involve, I cannot yet guess.

Fried tofu recipe

Given how many vegetarians read this blog, I thought I would share the delicious method of cooking tofu that Hella Stella taught me. It has three relatively simple stages: marinate, bread, and fry.

Marinate

Put 1 cubic centimetre blocks of tofu into a large pan. Immerse them in a marinade that includes the following:

  • Half a cup apple cider vinegar
  • 3/4 cup tamari
  • 1/4 cup water
  • One and 1/2 tablespoons sunflower oil

This should produce enough marinade for about 250 grams of tofu.

Apparently, if you seal and refrigerate the marinade/tofu mixture, it is good for three days.

Bread

In a large bowl, mix the following for the coating:

  • One cup flaked nutritional yeast
  • 1/2 cup wheat germ
  • 1 tablespoon garlic powder
  • 1/4 tablespoon sea salt
  • 1/4 tablespoon black pepper

Mix the ingredients and you have a coating that keeps indefinitely, as long as it hasn’t been contaminated by tofu. I plan to mix up a big yoghurt container full, to break out whenever I want fried tofu.

To bread the cubes, just roll them around in the coating until they are covered. The same coating can be used with pieces of eggplant.

Fry

Put about half a centimetre of sunflower oil in a frying pan. Place the breaded cubes in the oil and wait until they are nicely browned on the bottom. Flip them over to cook the other side.

Finally, place the fried cubes on a plate with a paper towel before serving the marinated and fried cubes with rice, vegetables, cous cous, or whatever you prefer.

Studio experimentation III

This weekend, I took my flash gear on location to shoot some baby photos for a friend of mine. Overall, I am quite happy with them. For the most part, they were taken using a shoot-through umbrella for diffusion, as well as manual flash power and aperture. A few use ceiling-bounced TTL flash, and others just natural light and a reflector.

As with the previous shots of my brother and tabletop objects, the linked image files have not been digitally manipulated.

At some point soon, I mean to experiment with shooting some backlit glass.

Studio experimentation II

Following up on my previous table-top efforts, here is a photographic lighting experiment on a human scale. My brother Mica kindly provided the material for the photons to bounce off of.

These all use manual metering for both flash and exposure (none of that ‘through the lens metering’ stuff). Lighting is provided by a 430EX flash, shot through an umbrella, and my white-on-one-side-soft-gold-on-the-other reflector.

As with before, these are original and unmodified files, with no after-the-fact digital alterations applied.

Greyhound’s pointless security

On my way to Toronto last weekend, I was subjected to Greyhound’s farcical new ‘security screening.’

People were made to stand in a line in front of a roped-off area. One by one, they removed metal objects from their pockets, placed them in a dish, and had a metal detecting wand waved over then. At the same time, another security person spent a couple of second poking around in the top few inches of the person’s carry-on bag. The person then entered the roped-off area, carrying their carry-on and checked bags with them, waiting for the rest of the line to be processed.

Ways to get a weapon past this system:

  • Get one not made of metal, like a ceramic knife, and put it in your pocket.
  • Put it below the top few inches of your backpack.
  • Hide it inside a hollowed-out book, inside a piece of electronics, etc.
  • Put it in your wallet. With a wallet that can take an unfolded bill, you could fit a few flat throwing knives.
  • Tape it to the bottom of your shoe.
  • Put it in your checked baggage, remove it while you are waiting on the far side of the line.
  • Go through the screening, ask to go use the bathroom, collect your weapon, and return to the ‘screened’ area.
  • Before entering the bus station, hide a weapon outside, in the vicinity of where your bus will pull in. Pick it up before boarding.
  • Use a weapon that is both deadly and innocuous: such as a cane, umbrella, or strong rope.
  • Get on at a rural stop, instead of Ottawa.
  • Get on in Toronto, instead of Ottawa, since they don’t seem to be bothering with the screening there.
  • Etc.

I am not saying that people should actually bring weapons on Greyhound buses, and I am most certainly not saying that Greyhound should tighten their security to make these tactics useless. I am saying that the new screening is nothing more than security theatre. It does nothing to make Greyhound buses safer, though it will add needlessly to ticket prices.

On a more philosophical level, it also perpetuates the kind of low-freedom, security-obsessed society that many people seem to expect. It would be far healthier to acknowledge that the world contains risks while also noticing that countermeasures to reduce those risks have real costs, whether in hard currency or in convenience or privacy or liberty.

Demise of a lens

The day after being re-united with my 50mm f/1.8 prime lens, I managed to break it into two pieces by accidentally smashing it into a wrought iron railing. Because of the Toronto snowfall, I was carrying my camera in ziploc bag. Due to the careless movement of my arm, a lens that I have used for years met what may be an untimely end.

I will investigate whether it is possible to have the two halves re-joined. If not, I will have to consider whether it is more sensible to replace the f/1.8 lens or buy the more expensive but more solidly constructed f/1.4 variant.

[Update: 29 January 2009] The word is back from the camera repair people. They estimate the chances of repairing the lens for less than the cost of a new lens at approximately zero. Also, it would take six to eight weeks. Eventually, I suppose I will buy a new 50mm lens.

Plea for photo gear

Anybody who can lend me the following piece of gear for the weekend will instantly earn a great deal of appreciation: a PC to Flash Hotshoe Adapter. That is to say, a device that can take the signal to fire a flash from a PC cable and feed it into the hotshoe of a flash.

I need it to connect a radio trigger to a 430EX flash. I ordered one online (since they are 1/3 the cost of buying one at Henry’s), but it won’t arrive until after I get back from Toronto on Monday.

Studio experimentation I

The photography class I was hoping to take at the Ottawa School of Art got canceled, due to lack of enrollments. Probably, that has a fair bit to do with the ongoing transit strike.

Nevermind. I can learn photographic lighting without the benefit of a class. I shot these on my dining room table. I used some tracing paper and my ironing board to set up a crude seamless backdrop (something more opaque would be better). For illumination, I used a hotshoe mounted flash. For light modification, I used a big round reflector: white on one side, soft gold on the other.

Because I have neither a wireless cable release (what a bizarre anachronism that term is!) nor an assistant, my basic approach was to turn the dining room lights on, focus manually, turn the lights out, point and set the flash, push the shutter (on two second delay), then dash into the right spot while holding my reflector.

These are all the original files, straight from the camera with no Photoshop tomfoolery.

Photography as hobby or career

Over on photo.net there is a good discussion of whether photography is a good way to make a living. The overwhelming response seems to be that it is an excellent hobby, but a very problematic career. It makes more sense to have a job to pay the bills; finance life, family, and photography; and allow you to treat the production of images as an artistic rather than a financial undertaking.

That coincides pretty neatly with my own intuitions about the matter. A few minutes on photo.net will turn up hundreds of top-notch photos. If the people making them are mostly warning of the difficulties of photography as a profession, it seems likely to be good advice.

Large-flaked snowfall

Lately, Ottawa has seen a bit of my favourite kind of snow: the sort where the flakes are large, slow to fall, and capable of being pushed and spun around by the wind. It is especially pretty to watch from inside a high tower, since the different air currents outside give the impression that as much of it is floating upwards as is falling down.

Despite the lengthening days, the good people of Ottawa still have a few more months in which to sample the many kinds of snow available, as well as the various winds that contribute to the mood of a snowstorm.
