A mystery: 3

Sommer Mathis clears up a mini-mystery for me: the original name of the Woodley Park Metro station (or Woodley Park-Zoo/Adams Morgan, if you must) was indeed Zoological Park. That explains the rail-to-bus transfer (in itself relic technology now) that I found in my deep book backlog; I was using it as a bookmark. It was stamped Zoological Park.

Cool running

Jonathan Erickson’s recent newsletter post for Dr. Dobb’s highlights a couple of the low-tech water development projects of Engineers without Borders: specifically, projects to bring clean drinking water to two villages in Honduras, designed and managed by USC students Liana Ching and Jackie Reed. Their scheme rests on

…a pair of 10,000-gallon storage tank[s] with a chlorination system (via tablets) upstream, away from the pollution.

But designing a system that would work in a remote village with no electricity is no small feat. The design they eventually came up with is a self-sustaining dam and water pump that uses paddles to carry water to a tank before it gets distributed by pipes to the villages.

“The students had to learn from scratch,” says Mansour Rahimi, their advisor and an associate professor of industrial and systems engineering. “There is no software, no tables or books on this.” Dana Sherman, a senior lecturer also in the industrial and systems engineering department, added that “the project involves so much more than just designing and installing a pump system…[it also involves] implementing a system that does not require consistent or difficult maintenance.”

Burgernomics, indeed

For the current issue of Scientific American, Nathan Fiala summarizes his own work as well as that of Susan Subak concerning the environment impact of producing beef, pork, and chicken—specifically, the contribution of livestock farming to greenhouse gases and hence to climate change. Some of the graphics include gratuitous elements or are poorly conceived, unfortunately something the magazine is becoming known for. But a key chart drives home the point: compared to vegetable production, growing meat makes a much bigger impact. While making a pound of potatoes entails generating 0.13 pound of CO2-equivalent gases, a pound of beef creates 57 times as much, 7.4 pounds of global warming gas. I would have preferred a closer apples-to-apples comparison that matched the various foodstuffs in terms of calories, and one that made it clear whether we’re talking food in the field or cooked, on the plate, but the force of the argument remains.

Fiala references the 2006 report from the UN Food and Agriculture Organization (FAO): Livestock’s Long Shadow. Going beyond livestock’s climate change effects, the report documents meat’s huge environmental footprint:

  • Livestock farming covers 30% of the planet’s landmass.
  • It is responsible for 18% of worldwide carbon dioxide-equivalent gas emissions, more than that of the transportation sector.
  • 8% of global water use goes into beef, chicken, and pork agriculture.

So it’s not surprising that the authors write in the Executive Summary:

The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global. The findings of this report suggest that it should be a major policy focus when dealing with problems of land degradation, climate change and air pollution, water shortage and water pollution and loss of biodiversity.

Livestock’s contribution to environmental problems is on a massive scale and its potential contribution to their solution is equally large. The impact is so significant that it needs to be addressed with urgency. Major reductions in impact could be achieved at reasonable cost.

Done moved on

A scent of hot dust, and some recollections are triggered. A sense memory that I’ve been meaning to write up for a while.

When I lived with my grandparents in Piqua, Ohio, in the mid 1960s, the Piqua Baptist Church sat at the northwest corner of Broadway and Greene Street. Dark, deep maroon-colored brick. Side entrance on Greene, which is where I usually entered. A Congregationalist church catercorner (no one could explain what was different about their faith), and another church (Catholic? Methodist?) up the block.

My grandparents were members, and one of my grandfather’s stewardship roles was non-resident caretaker of the facility. I think he preferred the term “custodian,” but frankly a lot of the work was janitorial. He was notorious for making the building a priority over everything else in his life; we had a tiff at my college graduation because he was anxious to get back home to check on the church. My grandmother helped him in his caretaking duties, and while I lived with them, I did, too. It was a painless way to earn my allowance.

Mostly what I did was to empty wastebaskets once a week. So I would make a circuit through the building, stopping in all the Sunday school rooms, the minister’s office, all around. Trash containers rank with stale lilies, used tissues, hardened chewing gum. The classrooms were arranged in a gallery along three sides of the basement multi-purpose room, with a kitchen at the other end. Walls faced with painted board and batten paneling. For the brief period of time that I was in Boy Scouts, our troop meetings were here. Stairways up to the rest of the church, and at the far end, a short flight to the furnace room, a convenient short cut back to the rest of the building.

The building was heated with a coal-fired furnace (hence my grandfather’s frequent trips to check on things). The furnace room was dark, but neither frightening nor particularly cosy. Just black dusty. From time to time, we all have the dream of moving through a familiar building, passing through rooms we’ve never seen before; for me, that dream usually begins in the church furnace room, where back in a corner is a door I’ve never seen before, that leads to someplace behind the baptistry, and on.

Back upstairs, facing the altar from the sanctuary, the baptistry was at the right, the minister’s office off left. The choir stood behind the altar. I don’t remember an organ, but there must have been one. Behind, and on the second story, were two rooms open to the sanctuary. I believe these were rooms set aside for mothers with infants, so that they could participate as much as possible without neglecting their babies. In one of these upper rooms I once found a booklet of devotions. The authors/editors were apparently holdouts from the Chicago Tribune’s spelling modernization plan, because each passage ended with a thot to be pondered.

Once I was finished with my chores, I would sit in the office, at the minister’s desk, and read whatever was available. Generally the calendars and addresses preserved under the glass desktop. I would play solitaire—that is, until my grandmother got wind of this. She didn’t actually call it “the Devil’s picture book,” but she made her feelings clear. (My grandfather, who would sometimes take me to play pool at his lodge, didn’t seem to mind.)

Each week my grandparents would dust the pews with ratty gray rags and fragrant polish. Once, I helped with a special project. In this church, communion wine was taken in individual glasses, in the pews. There were racks for the used glasses in the pew backs, on either side of the hymnal racks. I seem to recall three holes per rack. It seems that the clatter of all those cordial glasses being racked at the same time got to bothering someone, so one week I helped put rubber gaskets in the racks. Much quieter.

The church has since moved to a new building. The Broadway and Greene site is a parking lot.

Almost two million people, seen from space

Via The Morning News, satellite imagery of the crowd(s) on the National Mall for yesterday’s ceremonies. What’s interesting about the picture is that you can see that people were clumped at the big video screens: it wasn’t the solid mass of people that it looked to be, foreshortened, from the Capitol. Also note the lack of bodies on the downhill slope west of the Monument, where the view would have obstructed.

Even though

And what amazes me as I hit the motorway is not the fact that everyone loses someone, but that everyone loves someone. It seems like such a massive waste of energy—and we all do it, all the people beetling along between the white lines, merging, converging, overtaking. We each love someone, even though they will die. And we keep loving them, even when they are not there to love any more. And there is no logic or use to any of this, that I can see.

Get me rewrite

A collaboration between students at Northwestern University’s Medill School of Journalism and the Cedar Rapids, Iowa Gazette has launched the demonstration project News Mixer, as reported by NU staff. News Mixer is a local news site powered by Facebook Connect, which provides the authentication mechanism; comments made by a reader of news stories appear in that member’s Facebook newsfeed. The experimental News Mixer provides three levels of structured commenting, from short quips to long-form letters to the editor. It’s assembled from open source tools—Wordpress, MySQL, Trac, and Django—as recorded in the project’s blog, Crunchberry Project. The project is one of the early fruits of a new program of scholarships to Medill for talented programmers and web developers, granted by the Knight Foundation.
