  • Math and the City – The same scaling laws seem to apply to both cities and organisms: infrastructure requirements per capita (or per unit body mass) go down as population (size) go up. Not so surprising, since both cities and bodies are connected to themselves by networks of wires (neurons) and tubes (pipes, transportation, blood vessels) (tagged: urban design economics sustainability transportation infrastructure biology )
  • Sustainable Transport that Works: Lessons from Germany – A 60 page report on how Germany has transformed its urban transportation systems over the Post-War period, moving toward more public transit and bicycle infrastructure, the costs, benefits, effects, etc. What has worked, and what hasn't. (tagged: bicycle transportation policy urban design system:filetype:pdf system:media:document )
  • NASA Gets Out of Satellite Servicing Business – And good riddance. Yes, the capability was amazing, but expensive and unnecessary. For the price of *each* Hubble servicing missions, we could have launched an entirely new Hubble-class telescope on a rocket. The shuttle is a solution in search of a problem. Someday we'll have a real reason to send people into space — e.g. long term scientific exploration of Mars, or if we're lucky, the beginnings of a two-world civilization — but until then, we're just going around in circles, and forking over hundreds of billions unnecessarily to the aerospace industry. Better them than the banks… but that's really no argument to stand on. (tagged: space nasa politics policy )
  • Buying farmland abroad: Outsourcing's third wave – I don't know how anybody can think this is going to work long term. The whole point is to have food when there's a crisis, but in case of crisis, these deals are going to go down hard, unless those on the receiving end are willing to deploy their militaries on foreign soil to protect their investment. Which isn't impossible, but certainly doesn't seem like a great deal for anyone. (tagged: agriculture food china africa sustainability economics trade )
  • Crack Gardens – No, not gardens in which you grow crack, gardens growing out of cracks. A little creative jack-hammering opened up some fissures in this concrete slab, out of which a garden now grows. An homage to the tenacious plants that will take our cities apart when we leave.

What Are Cities For?

Kurt recently asked me:

Assuming (1) that you like the outdoors, open spaces, gardening, etc. and (2) that you would prefer high-density urban design to low-density, suburban, car-oriented sprawl, then how would you fuse these two together in an ideal town? If my assumptions are wrong, I realize my question is moot.

I am asking because I like the idea of owning acres of land, but not the idea of having to drive everywhere, and I wonder if those two desires are mutually exclusive.

and it got me thinking about what my ideal city would be like, and how close one can get to that in this lifetime, especially on this continent.  I’m going to make this an exercise in creative idealism.  Kurt’s assumptions are right, and I do feel torn, especially having grown up in a rural area, on 8 acres of oak woodland with a creek running through it.  I am completely sympathetic to the pastoral urge, but that urge is not and never has been satisfied by the suburban existence which has come to typify the American experience in the last half century.

Pasadena Bicycle Master Plan Workshop #2

Update August 4th, 2009: The BMP revision is taking longer than initially planned. See this post and the comments from Rich Dilluvio for more information.

After voting to bankrupt California, Michelle (here’s her take on the workshop) and I headed over to the Pasadena High School cafeteria for our second civic duty of the day: the 2nd Pasadena Bicycle Master Plan Workshop.  Ryan Snyder (the consultant drafting the plan) and Rich Dilluvio (Pasadena DoT) claimed that at some future date a revision of the BMP “Goals, Objectives and Actions” document (which I have transcribed below) would be posted on the web somewhere, but no timeline for that was suggested, and given that in February they said we’d have 4 public meetings before the draft plan was finalized in June, and we’ve only just now had the first one, and the first bicycle traffic counts were promised 6 years ago and still haven’t happened, I’m not going to wait on them.

First Chantry Flats S24O

Michelle and I went on our first S24O (sub-24hr overnight) bike trip last weekend, up in the San Gabriel mountains, above Chantry Flats on fire roads.  Despite some ill-timed road maintenance in Santa Anita Canyon, everything went wonderfully.  We got checked out by a fox near the ranger station for like half an hour, as little as 6 feet away, and had a beautiful full moon ride all alone the whole way.  Our dynamo powered headlights were plenty bright too, even for the dirt road, which I’d been worried about.  Read the full post for photos (and my first attempt at embedding a Flickr set in a post…)

  • The Missing $1,000,000 Tax Bracket – There's a fair amount of debate over what the "top marginal tax rate" should be, but it's infrequently noted that there's actually vastly more variation in the income threshold at which that rate becomes applicable. In inflation adjusted dollars, it's fluctuated between around $80,000 (Regan) and $80,000,000 (!) during the Depression. Ignoring this while debating the highest income tax rate is kind of absurd.

  • True Traffic Tales – Ah, bikes and cars living harmoniously together. (tagged: cartoon bicycle transportation )
  • Evangelical Climate Initiative – A Christian take on climate change, given its reality, what is the appropriate response for a conscientious person of faith? From my point of view as an atheist, it's not so important what other peoples' motivations are for taking action, as long as they take action. I'm curious how this has been received by the evangelical movement. (tagged: religion climate science christian green )
  • Sailfish Cooperating to Hunt Sardines – I had no idea sailfish were so colorful (and changeable), let alone this cooperative. Glad National Geographic still exists, even if our maps no longer have "Terra Incognita" on them (tagged: fish cooperation nature )
  • Communicating the Second Premise: Whether Obama or Bush, Values Drive Science Policy Decisions – A good look at the division between science facts/findings and science policy in the context of stem cell research and Bush's vs. Obama's take on it. Facts alone do not imply any "shoulds". We need values to tell us what's right or wrong. Sometimes those values are so obvious we don't even think about them, and sometimes they're not, especially when new and poorly understood technology is involved.
