Volcano for Monday

How about Mammoth Mountain this week. It’s quite the pretty mountain, and sits right next to Long Valley Caldera.

Now, the cool thing is that this volcano formed pretty rapidly – in about 2000 years, which is fantastically fast for an 11,000 foot volcano – during an eruptive sequence of the caldera. A study has recently been done on the age of the rocks there.

The Long Valley Caldera has also been in the news recently, with an article on MSNBC talking about the two different kinds of eruptions the caldera has produced. The article mentions a recent study on the radioactive isotopes in the rocks; I’m thinking that it’s the same study that the Mammoth Mountain article talks about.

Also, speaking of calderas, Valles Caldera has a new science center. If only it had been open last year, when I did my field class in the area!

texas scares me

Ding, Dong, McElroy’s out…

The Atheist Experience in Austin Texas talks about the developments for Texas’ board of education election this year. It’s not exactly a clear, sweeping victory for science and reason, but McElroy is well and truly out, having been knocked out in the primary.

We’ll see how things shake out, but it does allow a spark of hope that the state of Texas won’t single-handedly destroy the quality of school textbooks for the rest of the country.

Though I will admit, I’ll miss the big lug just a little. He was always good for a cringe-inducing quote that would leave me torn between despairing laughter1 and that face you make when you accidentally drink sour milk.

1 – Or possibly a Joseph McCarthy-esque eerie giggle.

A quick writing note

My blog entries are probably going to be a bit scarcer than normal over the next two weeks. I’m in a small writing group with three friends, and we’re doing a challenge: write a 15K word story in 14 days. So a lot of my writing time and energy is going to be taken up doing that. It’s something of a poor man’s NaNoWriMo for people who can’t commit to a whole month of frantic (and twice as intense) writing.

I actually have a lot of love in my heart for NaNo. I participated in it for four years in a row and got two completed rough novels, a half finished mess that still has a lot of potential, and an absolute embarrassment that ought to be set on fire before it can escape my hard drive and hurt people. I just haven’t been able to do NaNo since going back to university, thanks to lack of time. And that hiatus will be going for at least a couple more years, since I’ll be in grad school. Oh well, perhaps some day I’ll get back in to the swing.

Either way, I’m expecting this challenge to be a lot of fun. The last couple of months I’ve been doing nothing but intense rewrites, so having an excuse to write some new stuff is a welcome change.

earthquake

It must be disappointing the tsunami didn’t kill thousands.

I had a very, very busy weekend, plus I don’t actually have broadcast or cable television in my house – Mike and I survive quite well with just an Xbox 360 and Netflix. So thankfully, I missed out on most of the burning stupid that characterized the coverage of the post-Chile quake tsunami. I think this article makes a fine example, though: Scientists defend warning after tsunami nonevent

“Nonevent,” my butt.

There is some wonderfully comprehensive ranting over at Geotripper about the tooth-grinding stupidity. Since Mr. Hayes has also subjected himself to the awful coverage that I’ve been able to mostly avoid, I definitely recommend reading his posts.
The Hawaii Tsunami a Nonevent? I Don’t Think So…
I Have a Dream… in which the 24 Hour Cable New Networks Serve a Useful Purpose

Indeed, sir. Indeed.

I’m glad that the people who were involved in the evacuation seem to be taking the right attitude about it.

Residents and tourists alike said they weren’t bothered by the evacuation and supported the scientists’ actions — even though the waves never showed up.

“We lost a lot of business,” said Sam Stewart of the Nohea Gallery in Honolulu, which closed for much of the day Saturday. “But it is good to know that the island has it together. We don’t want to make this a regular drill, but it’s good to know we can get prepared. … Now it’s important to get back to business.”

I’m just seriously concerned that if this “scientists cry wolf” drumbeat keeps going, the right attitude won’t be present the next time there needs to an evacuation. One would think that “better safe than sorry” is the best attitude to take, in a situation when there is no such thing as 100% certainty and the potential for destruction and loss of life is high. But I suppose that would be the adult attitude to have, as opposed to petulant disappoint at the lack of something explodey to show repeatedly on a news station.

Volcano for Monday

How about Mt. Churchill, a very pretty glacier-covered stratovolcano1 that’s just on the Alaska side of the Alaska/Yukon border. It’s not far from the coast either, and is yet another volcano that sits on the subduction zone around the Pacific rim. It hasn’t erupted in the last thousand years.

All of this, of course, is a lead up to frozen dead caribou. Because those things often go together. Basically, it’s been found that the modern day caribou population is very genetically different from the one that lived in the area over 1000 years ago, which points to there having been a significant migration at some point. Since Mt. Churchill last erupted around that time, the two events are probably linked.

I always find it interesting when a volcanic eruption can be linked to events in our own history (such as the Minoan eruption) or biological changes. Any time I see multiple sciences coming together to form a picture of the past, it makes me happy.

1 – The Canadian site lists Mt. Churchill has a shield volcano for some bizarre reason. Every other catalog I checked, such as the Alaska Volcano Observatory calls it a stratovolcano. Considering its location on the Pacific rim, stratovolcano makes a whole lot more sense.

awesome science fair

Denver Metro science fair

I spent most of my day yesterday at the Denver Museum of Nature and Science as a judge for the Denver Metro Science and Engineering Fair. I thought the Denver Public School science fair was going to leave me feeling more confident, but I was wrong.

The environment was just very different. At the DPS fair we had to look at four or five projects over the course of two hours. At this fair, it was 10 projects in the same amount of time, and this time I also didn’t have a partner. There were two other judges looking at the same ten projects as me, so it meant we got to chat about them a little, which helped. But I was on my own with talking to the kids, and that was a bit nerve wracking at first just because I wasn’t quite sure what questions to ask. Then again, with 10 projects and only two hours, I didn’t have a whole lot of time to spend with each kid; a little less than ten minutes to talk, and then a few minutes to go off in a quiet corner to write some comments on the scoring sheet.

I’m not the best at talking to people I don’t know, but I think I muddled through well enough once I’d had a couple practice runs. I basically started off by asking the kid to just describe their project to me and tell me why they had wanted to do it. From there, I was normally able to find a couple of questions to ask, like, “How many trials did you run?” or “Which variables did you control?” or even, “If you had this to do over again, what would you change about your setup?” I actually got some extremely good answers for that last question, which made me happy. A big part of this sort of experimentation is running one experiment, figuring out all of the things you did wrong that make your results less than useful, and then trying again with the design flaws fixed.

This time I was also dealing with a higher grade level – the junior division, 6-8 grade – as well, so the projects were understandably more complex. I was put in the physical science category, which I felt a little out of my depth in since I’m not a chemistry or physics person. Then again, we weren’t really dealing with chemistry/physics more complex than you’d get out of your first two semesters, which is still impressive in itself when you realize that it’s middle school students working on these projects.

Aside: Some of the kids I spoke with were as tall as me. This should be illegal.

Overall, the quality of the projects was extremely impressive. I can’t imagine being able to come up with anything as cool as some of the experiments now, let alone when I was thirteen. I’m not going to say anything about the winning or favorite projects at the moment, since I checked the schedule and the awards ceremony isn’t actually until tonight. And while I doubt that any of the three or four people that read this blog have kids that participated in the science fair, if I’m putting this out on the internet I think it’s best to just keep it under my hat.

Several of the kids I talked to pointed to an episode of Mythbusters as the reason they wanted to try a particular experiment to see for themselves. Warm fuzzies all over again for that. One of the projects that I saw (though it wasn’t in my category) even had “Myth Busted” in its title. I was also incredibly happy to see a lot of young girls with some really fantastic projects and a lot of enthusiasm for the scientific process.

I’m still trying to mentally sort through my day. It was bigger, louder, and much more hectic than the other science fair, as one might expect. I’m considering seeing if I can volunteer for the Colorado State science fair. I think it’d be a great experience to spend a Thursday in April feeling completely stunned by how much smarter than me a bunch of teenagers are.

Big Brother is watching students (II)

BoingBoing is doing a fantastic job adding more and more to this already horrifically creepy story about school issues laptops being used to spy on students. I’m glad to know that the EFF and ACLU have gotten in on this now.

Anyway, a couple highlights, about the district policy:

* Possession of a monitored Macbook was required for classes

* Possession of an unmonitored personal computer was forbidden and would be confiscated

* Jailbreaking a school laptop in order to secure it or monitor it against intrusion was an offense which merited expulsion

Honestly, it’s got to be pretty cool if your school district has so much spare money that it can afford to get laptops for its students and loan them out1. If nothing else, making sure kids are up with the technology from the start gives them a good advantage, I think. But when it tips over in to requiring that students use these laptops and punishing students that have a different laptop they want to use, that’s creepy, and I really makes it sound like the intent from the start was to tightly monitor the kids. I could even maybe understand it if they were focusing on in-school use, since letting kids have laptops in class is a recipe for not getting anything done unless there are some real restrictions on what they can do with those laptops2. But that this overbearing monitoring extended so obviously outside of school makes it impossible for me to see it as anything other than intrusive and just… creepy.

And they sure were. A little more detail on the kid who was punished for something he did at home:

However, the lawyer for the Robbins family says that their son was called into the vice-principal’s office and confronted with a photo secretly snapped by his laptop’s webcam while he was eating Mike & Ike’s candy, and he was accused of taking drugs.

Way to go, Lower Merion School District. Way to go. Even if the kid were actually taking drugs, doesn’t that become a law enforcement issue if it takes place off of school grounds? Oh yeah, except the police can’t do that sort of thing without a warrant. Thank you Fourth Amendment.

From an article about the response of the EFF and ACLU:

Even if the school district had gotten students or parents to agree to the monitoring as a condition of receiving the notebooks, the spying would have still be unconstitutional, according to Bankston. He told us that private schools or employers can ask you to sign away your right to privacy, but not a government entity like a public school. “To condition one’s receipt of government benefits on your surrendering a constitutional right is itself unconstitutional,” he said.

Of all things, this is making me think of one of my favorite movies, Enemy of the State; toward the end, one of the shadowy bad guys, Tom Reynolds, is trying to justify how important it is for the government to spy on people:

We won the war. Now we’re fighting the peace. It’s a lot more volatile. Now we’ve got ten million crackpots out there with sniper scopes, sarin gas and C-4. Ten-year-olds go on the Net, downloading encryption we can barely break, not to mention instructions on how to make a low-yield nuclear device. Privacy’s been dead for years because we can’t risk it. The only privacy that’s left is the inside of your head. Maybe that’s enough. You think we’re the enemy of democracy, you and I? I think we’re democracy’s last hope.

The idea of course being that privacy (and in many ways, personal freedom) should take the back seat to the illusion of safety. If my earlier rantings didn’t make it obvious enough, this is not something I agree with. And while I understand not wanting kids to use school issued laptops to surf porn during class, the entire concept of the web nanny is famously flawed. And I also tend to think (admittedly, it may be easy for me since I’m not a mom of a kid of that age) that treating a kid like he or she lives in a police state isn’t going to do them any favors when they turn 18.

These are big issues that get bigger each day with the march of technology. David Brin has an interesting take on the issue of surveillance, transparency, and privacy in the Transparent Society. I don’t agree with what Brin says in a lot of ways3 (I tend to agree more with Bruce Schneier) but one point he does make well is that a major problem in surveillance is that it only goes one way. The government (in this case the school) is able to spy on you without your knowledge, and there’s very little that can be done to hold them accountable unless they do something phenomenally stupid, such as trying to suspend you for eating candy in your own home. The students are not allowed to monitor the school to make sure that the school is acting with the same responsibility that it is demanding of its students.

Larry King got the last word in Enemy of the State, and I think he deserves to have it here as well.

How do we draw the line – draw the line between protection of national security, obviously the government’s need to obtain intelligence data, and the protection of civil liberties, particularly the sanctity of my home? You’ve got no right to come into my home!

1 – Though also knowing of many a district that can’t even afford to get its kids new books while others can do this kind of extravagant spending tarnishes the shiny.

2 – I’ve been in a lot of lecture halls and watched a lot of supposedly more mature and restrained university students use laptops. I can count on the fingers of one hand the times that said laptop usage involved actual note-taking rather than Facebook and Youtube.

3 – Another of Brin’s ideas is that in a truly transparent society, everyone would be familiar with everyone else’s secrets, which leads to a sort of mutually assured destruction if we don’t respect each other’s illusion of privacy. Interesting, but not a place I’d personally like to live in.

The canyons of Mars

Super cool post over at Phil Plait’s blog in regards to an oblique view of an exposed section in the Gale Crater on Mars, courtesy of NASA. This is some exciting stuff if you’re a sed/strat nerd like me. Outcrops are the bread and butter of any geologist – unless you’ve got the money to drill cores or shoot seismic, subsurface geology is inferred from outcrops – and this one looks quite beautiful.

I just wish NASA would tell us a little more:

Layers near the bottom of the mound contain clay and sulfate minerals that indicate wet conditions. Overlying rock layers contain sulfates with little or no clay, consistent with these layers forming in an environment in which water was evaporating and Mars was drying out.

Since of course I’m immediately dying to know what sorts of clays, and which sulfate minerals. I’m thinking that when they’re talking about sulfates consistent with Mars drying out, it’d be sulfate evaporites like gypsum, barite, or anhydrite. Which then allows my fevered imagination to bring forth images of the Paradox Formation in eastern Utah and Colorado.

Of course, I have to stop myself from getting carried away here. The Paradox Formation is in places thousands of feet thick and covers an enormous area, which is what allows it to have such a profound tectonic effect on the landscape. Looking at that outcrop, I’m having a hard time getting a sense of just how thick the evaporites would be, but probably not that much. But what it does say, about the existence of water on the surface of Mars in the past, is pretty huge. And of course – letting my imagination run just a little wild here – opens the possibility of more evaporite deposits lurking under the surface, and bigger ones, and somewhere out there, one of the salt tectonic guys is going, “squee!”

Volcano for Monday

It’s a twofer: the NASA Earth Observatory captured Klyuchevskaya and Bezymianny on Russia’s Kamchatka Peninsula erupting simultaneously. Pretty cool stuff. Like Sakurajima last week, both of these are composite volcanoes that live on the rim of the Pacific plate, which is a zone of active subduction. Volcanic rumblings in that area are never a surprise.

It’s as if we’ve caught a hint of a new competitive sport played out over a geologic scale – artistic erupting! While these two volcanoes really get points for being coordinated, I’ve still got to give Sakurajima the lead, though. I’m a sucker for volcanic lightning.

Big brother is watching students

School used student laptop webcams to spy on them at school and home – via BoingBoing. This is absolutely ludicrous. A school issues laptops to its kids, then proceeds to use those laptops to spy on them while they’re at home. And apparently in one instance, even disciplined a kid for something that they did at home.

This is beyond horrifying. You can argue that personal privacy is a changing landscape right now, as society adjusts to the realities of new social media and the basic fact that on the internet, nothing is ever truly dead. That’s why you get messes where commentary on Facebook causes trouble or stupid use of social media gets you fired. There are arguments that can be made on either side for that kind of thing1. But using a laptop to spy on someone – anyone – in their own home is something I’d hope anyone that’s not on a fascist big brother-esque power trip can agree is beyond the pale.

“We noticed you checking out some stoner sites, so we’ve informed your parents that you’re doing pot and will be suspending you. Oh, and those were some cute panties you had on yesterday.”

I’d be calling myself paranoid, except that it’s actually happened. It’s apparently time to take the tinfoil off of your head and put it on your laptop instead.

1 – I am solidly on the side of “it’s none of your damn business what I do outside of work/school as long as I’m in no way representing the company/school.”
