Looking back at my ASI years
I'm a geochemist. My main interest is in-situ mass spectrometry, but I have a soft spot in my heart for thermodynamics, poetry, drillers, trees, bicycles, and cosmochemistry.

Cordierite is a high temperature metamorphic magnesium-aluminosilicate. It is interesting because it contains no water in its structure, but contains large channels (see picture) into which water will readily bind, with up to about 1.2 H2O per formula unit (Mg2Al4Si5O18). Unlike most non-structural water, cordierite can hold onto water in this site under very high temperature conditions, such as granulite facies metamorphism.
Because the water is not bound to a specific site, it has high entropy for a non-vapor phase, which of course explains the high temperature stability. It also leads to some funky phase transitions.

1. Some rock types common to Gulf oil deposits, like salt, don’t fuse into rock when heated- they just melt, become radioactive, and then redissolve into groundwater.
2. In big depositional piles like the Mississippi delta, the sediment is over ten kilometers thick. As it thickens, the pressure and heat created by burial squeeze the water out of the lower sediments. This water can then dissolve the radioactive bomb material and leak it up to the surface.
3. Outside the immediate blast zone, you are likely to create lots of fractures by breaking the rock.
4. The 2 billion year old natural nuclear reactors in Gabon show evidence of hydrocarbon migration. So it’s been tried before.
5. At the pressures found below the sea bed in a mile of water, (over a hundred atmospheres, depending how far below the sea floor you are), the cavity formed by the detonation is likely to collapse, so you don’t actually seal anything.
6. Do we really want oil-producing countries like Iran, Venezuela, and Lybia to think that if they just spill enough oil, they will have a justification for building a bomb?
7. Radioactive Cajun shrimp.
8. When’s the last time a solution for fixing a geological problem devised without consultation with Earth scientists actually worked? Hint, the correct answer is not the tube wells of Bangladesh.
9. Got a 6 inch nuclear weapon? That line may work on the ladies, but here in the real world if your bomb is bigger than the pipe, you’ll need to drill a relief well to get it down there.
10. If these guys can’t even drill a hole in the ground without blowing up their rig, do you really want to trust them with a nuclear weapon?

The MSM and the blogosphere have reached a feverish pitch reporting this week's oil spill in the Gulf of Mexico. While it is still too early to say what the end result will be, here are some previous oil apocalyptic scenarios that the doom-sayers seem to have forgotten.
Over the past 50 years, oil production in the Niger delta has resulted in spills estimated to have exceeded one million tonnes (~7 million barrels) in total. The result has been widespread chronic illness, environmental degradation to tropical rainforest and mangrove habitat, and severe social unrest.
During the 1991 Gulf war, Iraq set fire to all of Kuwait's oil wells and spilled close to a million tonnes of oil into the Persian Gulf, partially as a deterrent to amphibious assault. Following the war, they drained most of the Tigris-Euphrates wetlands in order to destroy the culture of the Marsh Arabs, who opposed Saddam Hussein.
In 1979 the Ixtoc exploratory well in Mexico blew out, spilling close to half a million tonnes of oil into the Gulf of Mexico.
In the 2006 Israel-Lebannon conflict, Israel bombed the Jiyeh power station, resulting in a spill of 20-30 thousands tonnes, and coating over a hundred kilometers of coastline with oil.
I'm assuming everyone knows about the 40,000 tonne Exxon Valdez spill.
In 2003 the Sea Empress spilled 70,000 tonnes of oil into an estuary in Wales. 200 km of coastline were contaminated.
The current estimate for the Gulf spill is around a thousand tonnes per week, although the uncertainty on this estimate is large.
Worldwide demand for oil is about 10 million tonnes per day. About one fifth of that is from the United States.

Back in 2005, Mrs. Lemming and I hiked the Grand Canyon, starting down from the south rim just as the Sun rose over the frosty cliffs. We were lucky enough to see not one, but two California Condors on our walk down.
Because the condor is critically endangered, all of the birds are labelled and tracked by conservation officers. A complete list of the birds released in Arizona can be found here. Browsing this list, I noticed that the bird pictured above is missing, presumed dead.
A brief correspondence with the conservation officers revealed that the bird disappeared in January 2009, just over three years after this picture was taken. If anyone has seen the bird since that time, please contact the Peregrine Fund via their web page.
The other bird we saw, number 72, is currently listed as "doing well in wild".

It's time to celebrate freedom from despotic tyrants, pyrotechnics, and BBQ. The first two aren't really big here in Australia, but the following suppliment to the third category makes up for all that.

People might get the false impression from this blog that I underestimate the risk of ionizing radiation. That is not the case. Radiation is dangerous. It is also well understood, and ubiquitous. A natural 400 KeV gamma ray will do just as much damage as a natural one, so treating the risks from them differently doesn’t make a whole lot of scientific sense.
That being said, one needs to respect nuclear materials. If you are going to build a nuclear reactor in your garden shed, there is a right way and a wrong way to go about it. The first half of the 20th century is full of tales of radiation-induced sickness that happened because people didn’t know what the risks were. We know now. So educate yourself, and be sensible of you are going to fool around.

The stellar system hosting this blog is characterized by two gas giants and two ice giants. These four bodies constitute 99.5% of the planetary mass of the system. However, there is a small amount of rocky matter orbiting close to the star Sol, which accreted in an area too warm for the ices to condense into proper sized planets. Although this part of the solar system is dynamically insignificant, great importance is placed on it by a particular species of bipedal mammal, as these creatures are unfortunate enough to live on the largest of these rocks. In the following picture, all three other planets and the planet-sized moon of the largest object can be seen behind the clouds of this largest inner planet’s atmosphere. Readers interested in the relative mass of these planets are referred to the rocky planet pie chart. Correct identification of each rock is left as an exercise for the reader.

There has been muttering in various parts of the internet about how some of the objections to Hillary Clinton's presidential bid might be sexist in nature. Although identifying bias in politics is less straightforward than in scientific publication, this hypothesis should be experimentally verifiable. In most elections, the people who actually run for office are generally not people's first choice. So for those who maintain that they have nothing against women presidents in general, but object to Senator Clinton in particular, I ask this question:
What women would you endorse for president, were they to enter the race tomorrow.
My short list:
Christine Todd Whitman
Olympia Snowe
Mary Jo White
I tag everyone who doesn't self-identify as a bigot.

Sir Edmund Hillary, the New Zealander who made the first ascent of Mt. Everest, died yesterday aged 88. There are tributes here, as we all as in any Australian, New Zealand, and Nepalese newspaper. What people who know of Hillary from trivia contests and NZ $5 notes may not also realize is that he followed up his ascent of Everest with a lifetime of service to the region, building bridges, airstrips, schools and hospitals. His climbing partner, Tenzing Norgay, died in 1986.

So as I complete yet another orbit around this pleasant G class star, I find myself approaching not just a new year, but a new epoch. I don’t know if it should be called the late thirties or the lower thirties, but it is certainly a greyer tick of the clock. Trouble is, introspective and profound aren’t strengths of mine. So instead I’ll talk about geologic time, the scale of which might actually make me feel young again.
All the world's a stage,
And all arachnomorpha merely players:
They have their exits and their entrances;
A trilobite in time plays many parts,
His acts being seven periods…

I actually had no idea that primaries had started until I say the results from Iowa this afternoon. And the year isn’t even a week old! I need to call the county clerk in the middle of the night tonight to figure out how to vote in this year’s primary next month- if, indeed, primaries allow absentee voting. I honestly don’t know.
The way I see it, an effective president needs to be able to do two things. First, he needs to have a strong enough vision to remember what he is trying to do amongst the turmoil of Washington. Secondly, he needs the political problem solving skills to accomplish those goals.
While I was back in the US, I watched a few of the debates. And came away with a couple of observations. Of the various candidates, only McCain, Giuliani, and Huckabee seemed to exhibit both of these factors. Romney seemed to be wheely and dealy enough to come to agreements, but he seemed very aimless in a John Kerry sort of way, and the fruitcake brigade did not demonstrate the pragmatism to actually accomplish anything.
As an aside, I would like to point out that Ron Paul happens to be my favorite flavor of fruitcake. He’s fun to listen to, and I’m glad he is in congress. But he would be a terrible president, as he exhibits none of the skills needed to successfully pass an agenda.
So. McCain, Giuliani, and Huckabee. Of the three, I think that McCain would send the country in the direction closest to the one in which I would like it to go. To be brief, Giuliani is a bit Jackbooty, and Huckabee’s a bit too preachy. As far as I know, McCain is the only candidate in any party- mainstream or fringe, who is both anti-surrender and anti-torture.
I also think that he would be the most effective of the three candidates at getting things done. He has a long track record of successfully making progress on important but unusual causes, such as normalization of relations with Vietnam and political corruption. And he is the only candidate with significant foreign policy experience.
As an expatriate, this is important. It seems hard to believe that when I first left America, most expats were republicans, and not ashamed of it. Things now aren’t quite as bad as they were in 2002-2003, when a Sydney barber fucked up my haircut the week before my wedding after I told him I was American, but I still get the feeling that people think we eat babies and destroy nations for kicks and giggles. I’m sick of apologizing of my nation- not to mention my political party- just because our president doesn’t understand the concept of adjusting to reality.
I admit that as am not as enthusiastic about McCain as I was in 2000. His campaign has been a bit of a mess. But then, we’ve had 16 years of Campaigners-in-Chief. So how about a president with a foreign policy track record instead of a teflon tongue?

Today's list of search terms that brought people to the lounge is somewhat more amusing than usual. Hopefully most of these people found what they were looking for. After all, what person googling 'hot chicks' isn't really dying to learn about the history of Thermodynamics? And if the person looking for a "sphalerite slogan" could come back and tell us what you came up with, I'm sure we're all dying to know.

According to today's New York Times, this year's Siemens science contest was won by girls in both the individual and team categories. Janelle Schlossberger and Amanda Marinoff, 17 year olds from Long Island, split the first prize in the team division, while Isha Himani Jain, 16, from Bethlehem, Pa. placed first in the individual category. The article notes that 11 of the 20 finalists were women, and that most finalists were from public schools, and had at least one parent who was a scientist.
