Weird stuff at UCSD surplus

Sunday, July 27th, 2008

Even by my standards!

First off, the scary sphere:

Check out the plate details:

Yep, that says ‘North American Aviation, Missile Division.’ I have no idea.

Now, if this doesn’t say ‘Death Ray Sci-Fi,’ what does?

(Especially with the blue center and handle, tres cool.)

Last but not least:

Well, maybe it is least, we used to use these in our labs to watch temp and humidity. Min bid $50, ouch.

Anyway, you can browse their catalog online, kinda cool. 

JavaOne and MBARI trip pictures

I was going to post these as a normal album on the photos page, but for some reason they’re crashing bins, my album software of choice. I’ve filed a bug, but for now I’ll use the Wordpress album feature. Enjoy!

Update 5/24/08: Bug fixed, courtesy of those lovely Debian developers. Album posted here.

Fly me to the moon

Wednesday, May 14th, 2008

(With apologies to Bart Howard)

Yep, NASA is running a promo for their return to the Moon, where your name goes onto a computer chip. Nearly free for them, good PR, and kinda cool at the same time. Our entire family will be aboard, though this is the first they’ll hear of it. ;)

Actually, you get a cool PDF with images and logos, nice piece of work:

Rampant sexism still flourishes

Tuesday, May 13th, 2008

 

Via Science in the News (good newsletter, by the way) a depressing article in the Times Online entitled ‘Sexist Culture Drives Women Out of Science.’

(The picture is Marie Curie, who knew all about science and sexism. Picture from Wikipedia.)

Here’s a long quote:

The majority choose their children and alternative careers instead of struggling with the hurdles of a macho “lab coat culture” with long hours, old boys’ networks and the risk of sexual harassment.

Sylvia Ann Hewlett, an economist at the Center for Work-Life Policy in New York and the lead author of the study, said the research had revealed a world with values seemingly stuck in the 1970s.

She said: “It has been a bit like a time warp. This predatory or condescending culture [towards women] was more common across the workplace 20 to 30 years ago but has somehow survived in an engineering, science and technology context.

“It is the hidden brain drain. We have this amazing, talented pool of women who have left the industry. It is highly destructive to our society and economy.”

I can testify to its existence, having seen the toll on friends and family alike. How’s this for pathetic?

The study, to be published in the Harvard Business Review on Thursday, found that while women made up 41% of newly qualified technical staff, more than half dropped out by the time they reached their late thirties.

Nearly two-thirds of all women surveyed said they had been victims of sexual harassment in the workplace. A similar number objected to the “lab coat culture”, in which researchers laboured over experiments, “tethered to the microscope”, for up to 12 hours a day.

More than half dropped out? Damn but we suck.

Ever wonder how a quartz crystal is made?

Thursday, March 27th, 2008


Ever wondered how the tiny quartz crystals in your watch, computer, TV, remote control, microwave, car key, etc are made? New Zealand manufacturer Rakon has a a very nice presentation of the entire process here, in either slideshow or single-page format. (The pictures are better in the slideshow)Very cool!  The first picture is of a multi-blade slurry saw, and the second is of the x-ray machine used to check crystal orientation… I knew that diffraction would show up here somewhere.

Laugh-out-loud chemistry humor

Wednesday, March 5th, 2008

Via Dan’s Data blog, a chemist blogs about chemicals he refuses to work with. And he’s damned funny.

That’s because the higher the percentage of nitrogens in the formula, the more you have to worry. Thermodynamically, nitrogens bonded to each other are always regarded as guilty until proven innocent - there’s always the fear that they’re going to find a way to throw off their civilized clothes and revert to wild nitrogen gas. That’s a hugely stable compound. If your structure goes that route, all that extra bonding energy it used to have ends up diverted into flying shrapnel and loud noises.

One carbon, one hydrogen, and nine nitrogens - look at the time! Gotta run!

Enjoy. It’s funny.

All about food coloring

Click for article

Click the link, but be prepared for an experience equivalent to reading “The Omnivore’s Dilemma.” Coal tar is in everything. Damn.

This one made me think

Monday, January 21st, 2008

Via Damn Interesting:

“It’s like… at my first job,” he continues, “I was stealing maybe a thousand bucks a month from that place. And this kid, he was new, he got wise. And he was going to turn me in, but before he got the chance I went to the manager and pinned the whole thing on him.” Now he is grinning widely. “Kid lost his job, the cops got involved, I don’t know what happened to him. And I guess something like that is supposed to make me feel bad, right? It’s supposed to hurt, right? But instead, it’s like there’s nothing.” He smiles apologetically and shakes his head. “Nothing.”

His name is Frank, and he is a psychopath.

Wikipedia clarifies that the correct term is antisocial personality disorder and defines it a bit more precisely: “The essential feature for the diagnosis is a pervasive pattern of disregard for, and violation of, the rights of others that begins in childhood or early adolescence and continues into adulthood.” (That’s actually from the DSM).

The essay is a good one, and really made me re-think some of the people I’ve known. One tidbit that surprised me is the prevalence - 1% for men and .3% for women. So it’s a statistical near-certainty that we all know a few of ‘em. (Update: DSM via Wikipedia claims 3% for men and 1% for women…scary.) Makes you think, doesn’t it?

One thing noted in the article is that the qualities that make them are strongly selected for in management - ruthlessness, self-confidence, charisma. Yay. What he didn’t note was that these qualities are also expressed by corporations at times; see The Corporation (2003). So it’s even more likely you’ve worked for one. Explains a lot, doesn’t it?

For instance, while it may sound like a cynical joke, it’s a fact that psychopaths have a clear advantage in fields such as law, business, and politics. They have higher IQs on average than the general population. They take risks and aren’t fazed by failures. They know how to charm and manipulate. They’re ruthless. It could even be argued that the criteria used by corporations to find effective managers actually select specifically for psychopathic traits: characteristics such as charisma, self-centeredness, confidence, and dominance are highly correlated with the psychopathic personality, yet also highly sought after in potential leaders.

In reading something like this, where you’re really reading about predators evolved to prey on non-psycho humans, one early reaction is “How do I tell if I’m dealing with one?” The article says that

The psychopath does not merely repress feelings of anxiety and guilt or fail to experience them appropriately; instead, he or she lacks a fundamental understanding of what these things are. When asked a question such as “What does remorse feel like?” for instance, the typical psychopath will become irritated, deflect the question, or attempt to change the subject.

Which makes me wonder if something like an fMRI would spot one. Lack of blood flow to regions involving affect, perhaps? Indeed, a quick search finds a couple that look like they might be doing just that (1,2). Hard to tell since just the titles are available. (I’ve ranted about this before.) PLoS to the rescue!

Bingo! “Law, Responsibility and the Brain” by Mobbs et al. Here’s a picture from that paper showing the brain scan of a sociopathic patient, with a lesion in the orbital frontal cortex:

A is the psycho, PLoS image

So there’s a lot of work on brain function and morphology correlating with anti-social behavior. How long until that becomes part of the hiring process, eh?

Update: For more info, “The Mask of Sanity” by Cleckley looks like a good place to start.

More fire information

Thursday, October 25th, 2007

From Scripps Institution of Oceanography:

SCCOOS has put together a collection of real-time data to support firefighting efforts in the 2007 Southern California wildfires, including meteorological station data, wind models, and satellite imagery.

We’ve also linked to the hpwren camera image site from our page.

You can find this data at:

http://www.sccoos.org/projects/fires2007

We appreciate your help in getting the word out to the community.

Ties together the previously-posted MODIS data plus weather and satellite visuals. Nice.

More fire satellite images

Thursday, October 25th, 2007

From NASA, of course. This first one is from the QuikScat satellite, 7AM 10/22. Wind speed via reflected radar on the water surface. Click for source page.

Vector field

The next one is visual, from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument on the Aqua satellite. 250m/pixel, 10/2. Again, click for source.

Visual, click for original

Found via Science in the News, wonderful stuff. Quite the plume, eh? I also like how the vector field shows the offshore winds that fanned the flames. Very cool.

Additional coolness: KMZ file of the MODIS for Google Earth!
