In class Peter Goldreich once said “You don’t get smarter in grad school. You just get older.” I don’t know if I agree entirely, but there’s a grain of truth in there somewhere. It is a strange kind of scientific hazing ritual. An induction and an indoctrination. Highly skilled and intelligent people, doing difficult technical work, for years, earning something close to minimum wage. Why? Is it for a chance to play in the tenure-track tournament, with the odds stacked 10 to 1 against you? If you win, you can study anything you like (as long as there’s funding…). Is it because we think having a PhD will get us somebody’s respect? Whose? Our parents? Our advisors? Society at large? It’s certainly not because we’re seeking power or riches. That way lies law school, or the dreaded MBA. Is it because we don’t know how to do anything else? Because our self esteem has been so entangled with school for so long? Because we are a people addicted to understanding? What fraction of PhD students finish feeling good about themselves, or in love with their research? Or even learning in general?
I have lots of draft posts in progress here on the back end, calling to me whenever I log in like internet sirens:
- The Scale and Form of Cities, about how one might design a city from the ground up today, with efficient resource utilization and conviviality in mind. A follow up to What Are Cities For?
- Corporate Paternalism, about the ways in which we (especially conservatives) seem to have more faith in corporations than our elected representatives when it comes to making decisions for us.
- Our Newtonian Hangover, about the non-linear, non-deterministic nature of history and technology, and James Burke’s excellent BBC series The Day the Universe Changed and Connections. Miraculously, they are almost as relevant today as they were 30 years ago, and we are in the process of implementing one of the strange futures he foretold.
- The dunes told me to work on passive buildings, which is a more personal and spiritual response to the NREL interview questions than seemed appropriate for a job interview.
- and a magnum opus entitled What’s Wrong With Graduate School, that examines both how my own graduate career has been uniquely flawed, why I believe the graduate education system as a whole is in general broken, and a vision of what I think higher education might look like by the time any offspring I could conceivably have would be there.
However, at the moment the thing most wrong with graduate school is that I’m still in it. My PhD defense has been tentatively scheduled for November 20th, and I’m going to the AGU fall meeting in San Francisco in mid-December to present my work, so I’m going to be completely occupied until the beginning of 2010. There will be no further blog updates between now and then. Or at least, there shouldn’t be. If you see me making posts, don’t read them. Instead ridicule me in person, or offer up some kind of digital castigation.
Of course, you can still read my mind keep in touch with me via my linkstream, my tweets, and my photos. Oh, and of course there’s always e-mail and the telephone.

At the Sustainability Symposium last night (which was nominally about water footprints (PDF) and this paper on the international trade in virtual water) we ended up “off topic” and talking about science communication, public outreach, and how policy gets made. Inevitably it seems like these conversations end up coming back to the issues from Chris Mooney and Matt Nisbet’s Speaking Science workshop that SASS sponsored last summer.
There is huge discomfort for scientists in the fact that the way in which information is conveyed impacts how it is interpreted. The idea is at odds with the scientific ideal of objective facts and communication, but nevertheless it is true. A one liter glass plus 500 ml of water equals what? The glass is half empty. The glass is half full. The glass is twice as big as necessary to hold that much water. The same objective facts, different connotations. Different implications. Different frames. And sometimes, the frame ends up being a more important determinant of the listener’s reaction than the information the speaker intended to convey.

Aaron suggested that my paper would would be much better if it read more like one of my blog posts, and less like a litany of torture lab notebook. So here it is in parts, written as if I intended for you, dear reader, to read it. (But don’t worry Bob, I’m actually working on the real paper). It’ll probably be cathartic, as one of the things I hate about writing papers is the formalistic language. It makes the content less readable, less enjoyable, less human. I just don’t see the point. If the content is up here, then anyone who feels the same way can get an idea of what’s going on without wading through all the passive voice crap. It’ll also help me enjoy writing it, and let me feel like I got it out of my system. Plus, on the internet, color figures are free (not $350 for the first page, $175 for each additional page… I mean jeez, that’s like a year’s worth of hosting fees just for one paper), you can insert links, and nobody has to pay $3975 per year for a subscription. Oh, and sweet, I also get to retain the copyright. Honestly, paper journals are so sad. Of course there’s that pesky peer review, but you’ll find a comment form at the bottom of the page, and if you actually make it that far, by all means let me know what you think. In a production environment, the publication would be hosted on a neutral third party site, precluding me from editing or deleting comments, verifying everybody’s identities, and ensuring that the content was archived effectively. Alas, we’re not there yet. Maybe this will seem ridiculous at this point in the grad school experience, but I actually maybe for the first time understand why someone would want to give a talk. I have results, they’re interesting (if you’re into this kind of thing), but I don’t really know what they mean.

- Here comes the data: OECD Factbook eXplorer – There are terabytes of interesting data out there that nobody can actually understand, because we don't have good interfaces for playing with it, and poking around. This is the OECD's attempt to offer a window into its own demographic treasure trove. Obviously inspired by the gapminder, from Google and Hans Rosling.

- The Choice of Cities – I'm not convinced we really know why the humans are coming to the cities. Whether it's a pull, or a push. How the migrants feel about their lot. Is it, globally, the same as the push we had in this country a hundred years ago? Or was it a pull? What happened when the frontier closed, when all the land was spoken for, and the factories and mines and mills were opened for business.
And what will cities look like once everyone has arrived? If we actually reach that day, when the countryside is emptied, and the flow staunched, then how will cities develop going forward? What will their margins look like? Will the slums filled with newcomers vanish? What will they be replaced with? (tagged: technologie urban design economics history technology poverty )
- Bike Among the Ruins – Detroit is half abandoned. The houses are almost free. The streets are empty and the people are poor. It's also flat. Could a cyclone of bicycles wipe clean the slate, even within the sight of our beloved, bankrupted, and now employee owned husk of an industrial titan… GM?

- The Revolution Will Not Be Digitized – Iran is one of the first places we get to see old school blood in the streets mixed with the new age of instantaneous, ubiquitous communication. We've tended to focus on the positive aspects, while briefly forgetting the potential powers of an electronic police state, which is to some degree what Iran has built. No massive army of eavesdroppers and informants is needed in such a regime. A few deep packet inspection boxes from Siemens sitting on the fiber backbone, and a few on the microwave towers from Nokia. Technology is largely neutral.

Even if the pessimistic IPCC scenarios are right, and even if they "only" reduce global GDP by 5% over the next 100 years, that purely economic metric is not sufficient, because it turns out you can wipe 2.5 billion people and their nations off the face of the Earth, mainly in the tropics, and only reduce global GDP by 5%. Cold comfort, that. (tagged: climate economics gdp )

- Property Assessed Clean Energy Bonds – PACE bonds are a way of overcoming the capital intensivity of many energy efficiency retrofits which make sense in the mid to long-term, but not on the typical short term investors time horizon. They also allow homeowners who may move before their investment in efficiency has paid for itself to pass on the obligation to future owners, instead of losing the investment. They also shift the costs of doing energy efficiency from capital expenses to debt servicing, which is advantageous in many jurisdictions for tax purposes. Berkeley, CA and Boulder, CO pioneered them for municipalities, but they can also work in a commercial context. (tagged: energy efficiency sustainability finance green debt investing bonds )
- It’s Now Legal to Catch a Raindrop in Colorado – Colorado has taken its first tentative steps down the road to legalizing… rainwater harvesting. I hope they go all the way. I'd hate to have to end up breaking yet another immoral law. (tagged: environment colorado water law sustainability rain green architecture design )
- Welcome to Tällberg – A "conference" analogous to the WEF in Davos, but held in Sweden, in the woods, and with sustainability as the given goal, instead of economic growth. Would be an interesting stop on the Green Cities Bike Tour. (tagged: green economics technology politics policy design conference )
- Power Struggle – A commentary on Steven Chu's position that we need major basic scientific and technological breakthroughs to successfully tackle our energy problems in the context of global warming. The hope is that in the short term, the vast array of incremental changes we have available is enough to get us started, and that by mid-century, the major breakthroughs will have been forthcoming. Ah, non-linear dynamics. (tagged: technology science energy climate non-linear sustainability policy )
- The Great American Bubble Machine – An article from Rolling Stone, by Matt Taibbi, on the endless bubble building shenanigans that Goldman Sachs has engaged in over the years, and their supposed current machinations to engineer a bubble in the as-of-yet uncreated market for greenhouse gas emissions. Markets, I like. Markets run by some Great American Gangster Kingpin, not so much. Especially not this particular market. Remember: Nature doesn't do bailouts.

- The Economics of Ideas – An article about Paul Romer by Kevin Kelly, musing on the problems and benefits of having an economy which is primarily driven by informational goods. (tagged: economics technology non-linear )
- Paul Romer: A Theory of History, with an Application – Paul Romer talks about two different kinds of informational goods: "technology" and "rules". The former being knowledge about how to re-arrange the material world to increase its value to humans, and the latter being constraints on the ways we interact with each other. His "new/endogenous growth" theory suggests that overwhelmingly, wealth creation throughout history has been due to these two kinds of goods, and that they are virtually infinite resources. What he does not explicitly admit in the talk though, is that much of our increased apparent wealth has come at the cost of virtual liquidation of material resources. Truly sustainable growth absolutely must close the materials loop somehow. Better sooner than later. The rest of his idea is wonderful: we need a system which enables rule set entrepreneurs, or we aren't going to get sufficient innovation in the field. He suggests myriad autonomous city states, and I agree emphatically. (tagged: economics urban society non-linear politics longnow )
- The Swimming Cities of Serenissima – Improvised and chaotic houseboats built from found bits, floating down the Mississippi (2006-2007), or the Hudson (2008), or sailing the Adriatic from Slovenia to Venice (2009). Like a tiny maritime Burning Man. Only a couple of boats today… What if it were an armada? (tagged: art boat performance sailing )
I went to this year’s second Everhart Lecture yesterday by Josh Spurgeon, who is working with Harry Atwater and Nate Lewis, trying to develop cheap, scalable solar cells. As with most of the Everhart Lectures, it was a very well presented talk. Unlike many of them, it was directly relevant to a real-world problem: how can humanity continue to utilize on the order of 10TW of power, without changing the composition of the atmosphere (see Nate Lewis’ excellent presentation for more information). The ultimate solution to that problem will almost certainly involve directly capturing incident solar energy, because the potential resource available is both vast and relatively concentrated, when compared to other sources of renewable energy. But solar has two very serious problems today: it is expensive (both in absolute terms on a per watt installed basis, and in an up-front capital expenditure sense), and it is not available when the sun isn’t shining. Whatever the solution looks like, in order to scale up to 10TW, it needs to use only earth-abundant, non-toxic materials. In semiconductor photovoltaics then, silicon probably has an unassailable lead. It’s the second most abundant element in the Earth’s crust, and it’s about as toxic as sand (though silicon semiconductor fabrication has serious toxicity associated with it and certainly needs to be made closed-loop). Exotic materials like cadmium-telluride, and copper-indium-gallium-selenide (CIGS) are unlikely to scale to tens of terawatts, simply because of the limited availability of elements like indium and tellurium. Additionally, owing to the vast silicon microprocessor industry, we are much better at micro and nano-scale manipulation of silicon than any other material on Earth (ignoring for the moment biological systems).
I can’t say that I’m surprised, but what Francis Collins presented in his talk last night at Caltech as constituting evidence for God’s existence was utterly unconvincing. However, what he said and the questions which followed were vastly better framed, less offensive, and in some important respects much closer to the truth than the talk that Richard Dawkins gave at Caltech in 2006 when he was touring for his book The God Delusion (which was ultimately so unpleasant and ill conceived that even I, an atheist who basically agrees with Dawkins’ criticisms of religion, am unable to recommend it). You can watch or listen to an earlier version of Collins’ talk on the Veritas Forum website. It’s in support of his own book, The Language of God: A Scientist Presents Evidence for Belief.
Went to Francis Collins’ afternoon talk “fireside chat” with David Baltimore on the future of medicine, as illuminated by genomic work. Too much introduction and rambling biographical information, but some good discussion anyway. I thought his best comments had to do with the positive effects of the open data model that the Human Genome project initiated – it’s had a long lasting impact on the entire field of genomics, and thank goodness! Also, he mentioned that as of now, there aren’t any major studies seeking to correlate and analyze the relationships between genotypes, phenotypes, and environment in the human population, and that such a study is really what’s needed to truly understand what’s actually heritable, what our real low frequency (rare allele) genetic variation is like, and what kinds of effects environmental factors play. He pointed out, interestingly, that we don’t need to wait until thousand dollar genomes are available to start this study – what we need to do is get people signed up, and start tracking their health history and environmental factors, and we can sequence them when it becomes cheap enough. He suggested that we ought to do this for roughly 500,000 people, and that it would likely cost on the order of half a billion dollars a year, and need to run for a few decades. And then we’d know, and medicine would be forever changed. He also suggested that those $1000 genomes are likely on the order of 5 years away. Really, once we’ve got fast, cheap sequencing – this study will almost do itself, so long as we can at some point get access to the medical histories and genomes of people. The real value add is in starting it now, so we have the information as soon as possible, and in getting all the environmental/lifestyle data, in addition to the healthcare records.
