A note about nodes

I was just reading Matthieu Aikins‘ GQ account of The Siege of September 13 in Kabul, when a couple of sentences caught my eye, not because of the attack itself, but because they reminded me of a point I want to make about the way we think these days about networks, nodes and linkages:

Salangi’s SUV was passing down the main road north of the embassy when the sound of gunshots and his police radio simultaneously erupted. He told his driver to turn around and head toward the sounds.

At Massoud Circle, the next roundabout down from Abdul Haq, they encountered a bottleneck of police vehicles, and so Salangi continued on foot, ducking as he heard the crack and whine of bullets passing close by…

What specifically caught and rerouted my attention was that phrase, “Massoud Circle, the next roundabout down from Abdul Haq” — Abdul Haq Circle, I’d read earlier in the article, “is a wide traffic roundabout named for a deceased mujahideen commander”, as presumably is the circle named for Massoud.

So we have two roundabouts connected by a road… and two deceased mujahideen commanders.

Or to put that another way, we have two nodes and a connection between them, twice over — in once case the nodes are places, and in the other the nodes are people.


Further into the article, I found a graphic showing the two places and the road connecting them — and an image of two people in Kabul that day, one extending an arm of care to the other. These two men weren’t Abdul Haq and Massoud, of course, but two people nonetheless. So in each graphic, we have two nodes and a connection:

A great deal of time and treasure goes into the analysis of networks of communication — cellphone to cellphone, person to person — or travel — place to place — (a) because the patterns can be revealing, and (b) because the data (what number called what number, e.g., how often Nidal Hassan emailed al-Awlaki, or what route bought Abu Dujanah from Amman to Khost) is unambiguous when obtained.


We’re also fond of neural nets, eh? — whether the “artificial” nets of AI or the “biological” nets of the brain — and again, these are unambiguous, scientists and technicians love them, and software developed with Congress-friendly budgeting implications is required to process them.

But what about ideas?
