This New-Fangled Technology

July 14, 2008 · 3 Comments

So my cell phone is almost a year old, and it’s the first time I had a camera phone. I know, I’m behind! I was amused at how many funny pictures of my friends that I’ve taken and at how many random pictures that I have. It’s a great opportunity to catch the unexpected. Here are some of my favorites from the latter category:

—————————————————————————-

Okay, seriously? How does one do that?

—————————————————————————-

Close up of a six-foot tall X-mas tree in a store window… made of naked Barbies, hair rollers, and grapes.

—————————————————————————-

Even bookstores need lovin‘.

—————————————————————————-

This is not a funny one, it’s historic. And I was glad to capture it! Too bad it’s, you know, now a parking lot.

—————————————————————————-

Ah yes, I walked into the lab to see this one day, and immediately thought we were under attack from the Daleks

—————————————————————————-

Check out the “Date of Birth” on my grocery receipt, after they checked my ID for my beer purchase. Not only is it not my birthday, but it’s not even close to my age. I got pegged as 16 the other day by a stranger, not 66. (If you’re interested, I was born in the year made famous by Orwell. And what I was making was Ukrainian red borscht soup.)

—————————————————————————-

My fellow heathen labmate and I saw that sign while on a work trip and realized we’d best stay away, give the orange sign’s proclamation. You think there’d be more info?

One day I’ll get an iPhone, and these picture will be awesome.

Prettier than Captain Jack's…

Tell me that this isn’t the coolest bracelet you’ve ever seen:

Wow! It’s like an abacus on your wrist! But the title of the actual webpage says the theme is time machine. I love it.

I was browsing the fabulous Charlottesville Farmers Market yesterday, as I like to do on Saturday mornings. I already had all the produce I needed from H&B, but was enjoying the sights, smells, flowers, and coffee. Usually I pass by the jewelry tables, since most of the handmade stuff looks similar to me after a while, and it’s not my style anyway. But a stand with more traditional looking jewelry caught my eye. But it wasn’t traditional at all! It was metal and gemstones in funky, interesting, geometric patterns. So I grabbed a business card and kept moving. I encourage you to check out the website as I did, since the artist has some really great designs! I’m not a jewelry person at all, and especially not expensive jewelry. But these designs fit my style. One day I may afford shiny things like this!

Seeing Aurora with Radio Eyes

July 12, 2008 · Leave a Comment

Seth Shostak of the SETI Institute recently wrote a very cool article about the radio signals corresponding to aurora as possible indicators of Earth-like planets. His methods of explaining the geophysical phenomena and astronomical techniques are witty and informative. He truly makes me happy for never using the word “listen” to refer to radio astronomy. Radio waves are light, not sound! Although you can turn the signal into sound, as alluded to in his first paragraph, but rarely with useful results.

Basically, aurora can be associated with massive radio signals, which could be a signal to ET that we’re here or for us to find ET! But actually using it for detection does not look feasible, since the Sun and gas giants like Jupiter and Saturn give off much more radiation due to their own processes. Aurora are the pretty display of lights created by ionized particles reaching the Earth’s atmosphere near the magnetic poles. As Dr. Shostak explains the radio emission, saying, “Auroral Kilometric Radiation… is generated when fast-moving particles boil off the sun, gush into space, and then get manhandled by Earth’s magnetic field.” That makes an amusing picture in my mind for some reason. There are ways in which AKR will be useful for “legions of grad students” to study. Read his article to find out more!

The Frakking Cracker of '08

July 11, 2008 · Leave a Comment

(Update at the bottom from 7/12)

Wow. So the Catholics are royally pissed at PZ Myers.

Those who frequent Pharyngula know PZ’s style of blogging. Some of it is super-cool biology, and some of it is commentary on the science-religion debates in the world and other topics. And frankly, his style can be abrasive, despite how mild-mannered he is when you actually hear him speak! I guess he fits in with the so-called “new atheists” who don’t think that any topic is above honest discussion and even humor. No holds-barred, and I totally respect that. Nothing is sacred, sorry folks.

So a few days ago he writes about a college student who smuggled a blessed host out of a Catholic service. The guy suffered death threats, and it was called a hate crime. PZ points out that it’s just a cracker… the murder of Matthew Shepherd is a hate crime. And as a “recovering Catholic” myself, I’m equally appalled at these comparisons, and I don’t think I would have ever been so indignant over such an issue. It’s absurd to compare this, even if you believe it’s holy, to kidnapping or murder, or to threaten violence over this! If you can put any religious prejudices aside, there are some very good points there in his post. To continue to point out the farce of the situation, PZ goes on to say that he’ll show them cracker sacrilege, just give him a chance! Funny stuff to most of his readers. So much so that there are multiple threads just to handle the comments.

Enter Bill Donahue, who apparently speaks for some Catholic group that I certainly never heard of when I was faithful, who threatened PZ Myers’s job for saying he would desecrate a Eucharist. Ok, Bill, go ahead and skip the biting commentary of the over-reaction and go right to the amusing “threat.” Oh noes, he’s going to be violent against FOOD. Sure, be indignant, send Myers hate mail, whatever. You can say whatever you want. But to demand his removal of tenure is just absurd. Donahue also doesn’t know the difference between a university webpage and a non-university webpage. And my favorite, “It is hard to think of anything more vile than to intentionally desecrate the Body of Christ.” Er, so hurting PEOPLE isn’t worse?!?!?!?! Next, PZ calls on his readers to write to his university president against Donahue’s ridiculous request.

But apparently, a mild-mannered biology professor is a violent scourge on humanity, and Virginia’s Thomas Foley requests additional security so that Catholics can worship without threat at the Republican National Convention 150 miles away from where PZ lives. Who-what-now? The persecution complex at work here is simply astounding. But then again, who better to understand persecution than a group that hangs a rather bloody symbol of it in the front of every church? (I’m so getting hate mail for that comment…)

The latest in this developing story is a good sample of the hate mail, the hundreds and hundreds of pieces of hate mail, that Myers is getting in regards to this issue. Something tells me that not one of these people actually ever read his blog. They were sent this link in an email or maaaybe saw it on the news and thought “OMG what a hateful attack!” and with no understanding of the issue at hand, the blog itself, or sometimes the basic tenants of their own religion, start spewing forth their opinion. THEY MISSED THE WHOLE POINT OF THE COMMENTARY! Now you can see how the college student who started this was quickly harassed for what was, in reality, not a huge offense.

I’m appalled and disgusted at the behavior of some of these people. And I’m saddened, but not surprised, by the blatant display of irrationality. Finally, I’m worried that those in academia will have to fear censure from their universities for expressing their opinions in private blogs. That last point is probably the most important in my mind, and I sincerely hope that the University of Minnesota, Morris, will understand that issue.

Update: Great coverage of this from blogger Zeno with more on the original case that started the craziness. Lousy coverage by the Washington Times, shame shame. And the battle rages on the comment threads still. It’s truly amazing…

It won't make a Fox special…

July 11, 2008 · 1 Comment

Eventually I’ll feel awake enough to be useful…

CVillians, there’s a little news story about a police chase that happened in and west of town this morning. Quite a list of offenses: “grand larceny, felony elude of a law enforcement officer, obstruction of justice, driving on a revoked license, reckless driving, vandalism and failing to obey a red light.” The reckless driving part includes passing me on the left on Garth Road where there’s no frakking lane to pass in! Jerk.

So I’m driving along Barracks where it becomes Garth, and this car followed by a police car turns onto the road behind me. Okay, it’s probably safe to assume that because of the other car in between, the cop isn’t trying to pull ME over. So either a) he’s pulling that guy over or b) he needs to get past both of us to an emergency. As I’m looking for a place to pull over in case it’s (b), the guy behind me pulls over to the left where the median is painted. And I think, “gee, that’s one way to get out of cop car’s way.” But then he’s speeding up and passing me, followed by the cop. That’s when I realize I’m witnessing a lowish-speed chase. And I can’t help but think, “c’mon, dude, really? You really think you’re getting away on these sparse roads with the cop right behind ya?” I promptly pulled over for cop car number 2, and watched 3 and 4 pass by later on. Lo and behold, the dude gets caught trying to escape on foot when he hits the end of a road. Again, seriously? What are you thinking?

I hope the owner of the car got it back in one piece!

These are a few astronomical things…

July 10, 2008 · Leave a Comment

Here’s some fun astronomy-related stuff that’s been keeping me entertained this morning while I simmered over having my water turned off for maintenance… again… without warning…

Dr. Guillermo Gonzalez was denied tenure at Iowa State for a myriad of reasons, not simply because of his involvement with the creationist Discovery Institute, which is claimed in Ben Stein’s Expelled. He is an astronomer, and now the Disco’tute is giving him a grant and a telescope to continue his research. So now, we astronomers have to worry about creationist or ID claims in the realm of astronomy just a little bit more. Hopefully I’ll be able to read some of his claims and be able to research the science relating to them. It’s been suggested to me that this has to do with the idea that the physical constants of the universe are set juuuust right so that life can arise. This is an old argument, and I’d like to know more about the actual error bounds that the constants have for creating matter as we know it.

In other astronomy news, a posting on astro-ph today is saying something that I like a lot, that we should abandon the teaching of the magnitude system in introductory astronomy classes. This came up in a teaching seminar in my department a few years ago, and there are two sides of the issue. Either you include it such that students can understand what they read in popular astronomy magazines about that “star of magnitude 5,” or you abandon it to avoid a somewhat more complicated method of describing brightness, and leave time for talk about physical explanations. On the one hand, it is interesting that the eye works logarithmically in discerning brightness, and this has historical significance in astronomy. On the other hand, most students will never run across magnitudes when reading about astronomy in the news, and will only come across it if they actually want to observe. The abstract even goes so far to say that professional astronomers should consider leaving the magnitude system in the past and move onto more physical flux units. Personally, I’m in favor of that, but am I just prejudiced because I work in radio astronomy? Let’s face it, a unit named after Karl Janksy is worthy of respect and more usage! Well, I haven’t actually read the whole article yet, but I look forward to it. And it’s something to keep in mind for when I have my own class one day.

Finally, a short, fun video lesson on Saturn’s rings from the Bad Astronomer! My favorite is the explanation of the Cassini Division. It’s a fun concept to draw on the board, too!

That’s all for now. Tonight I start up astronomy tutoring again, and then I get to explore the universe with a Girl Scout troupe!

P.S. The post title comes from a song written by my undergrad astro prof, set to “My Favorite Things.” I wish I could find the lyrics!

My head officially asploded…

You know Ray Comfort, the “banana is an atheists’ nightmare*” guy? Pharyngula links to the latest intellectual debauchery from this man. As a physics-junkie, I’m horrified to the core.

*I would link to the YouTube video that famously debunks the banana argument, if only the astronomy presented in it wasn’t so horrible.

Spirit of Exploration

July 6, 2008 · 3 Comments

You can’t convince me that the spirit of exploration is dead when you hear stories like this:

Using his trusty BB gun to help him return to Earth, a 48-year-old gas station owner flew a lawn chair rigged with helium-filled balloons more than 200 miles across the Oregon desert Saturday, landing in a field in Idaho…

“If I had the time and money and people, I’d do this every weekend,” Couch said before getting into the chair.

With picture goodness!

Neo's Got Nothing On Us

Great post I found at the latest Carnival of Space, about living with a love of astronomy.

Speaking of which, if you are in Charlottesville, check out the Charlottesville Astronomical Society, the group that sets up their awesome telescopes at the Fan Mountain public nights, and have monthly meetings at the observatory with talks and use of the 26-inch telescope. Maybe if I hang out there enough, I’ll finally learn how to use my 90mm Meade!

P.S. Happy 4th, you liberty-lubbers :-)

(Edit: that’s 90mm, not 90cm, duh.)
