(S)quid pro quo

Look. I can only handle so many horrifying attacks from PZ’s squid-inked poison quill (like here, here, here, and here, and here, and here, and here). Plus, as of this writing, he has 500 more votes than I do (he’s at roughly 3200 to my 2600 at 11:00 p.m. Pacific time Monday night 3490 to my 3270 as of 10:00 a.m. Tuesday).

It’s not that I want to win, really, so much that that we must stop the tentacled and literally spineless horde from winning.

And to that matter, I have a cunning plan that cannot fail.

If you have a blog, post an entry telling people to vote for me. Then come back to this entry and leave a comment with a link to your entry. On Friday, the last day of the voting, I will post the list of people who supported me with the links to their blog or site!

Let’s be honest: I get more than 12,000 readers to every post. I’m not sure how many more, but that’s the number from hits to the site plus people who come in through Feedburner. That’s a lot of eyes seeing your site. So plug away! Tell people you have bones, and you’re proud of it.

To let you display your support of vertebrates, if you plug Bad Astronomy, you can put this handsome banner on your site:

I have created three versions: big (1000×555), medium (500×278), and small (250×189). Take your pick.

Honestly, even if you don’t vote for me I can’t stop you from using the banner. But I also know I have the most honest, wonderful, and — let’s face it — best-looking readers in the observable Universe (and that includes the depths of the ocean), so I know you’ll help out in this time of need.

But hurry! Voting ends on Friday!

12,000 people. Hmmm, that’s a lot of folks who have not yet voted for me. I’m just sayin’.

Tip of the voting lever to good ol’ Fraser of Universe Today for this wonderful idea. He’s a man of true calcium.

How big is your ’scope?

… because I bet the Europeans have plans for a bigger one. A way bigger one.

They just released an announcement that they will fund a study to build a telescope that is so big that it has been informally dubbed the Extremely Large Telescope, or ELT:

European astronomy has received a tremendous boost with the decision from ESO’s governing body to proceed with detailed studies for the European Extremely Large Telescope. This study, with a budget of 57 million euro, will make it possible to start, in three years time, the construction of an optical/infrared telescope with a diameter around 40m that will revolutionise ground-based astronomy.

42 meters (the actual planned size) is pretty frakking big. That’s a mirror nearly 140 feet across!

To give you an idea of how ridiculously huge that is, here’s an artist’s conception of the observatory:

See those two dinky sticks and a longer dinky thing next to them in the lower left? Those are two people and a pickup truck (click the link to see some bigger images; they’re pretty nifty).

Like I said, frakking big.

The biggest optical telescope in the world is the Keck 10 meter in Hawaii (technically, it sees in infrared, and there are two of them). The ELT’s planned 42 meter mirror means it’ll have 18 times the surface area, so it can see object 18 times fainter in the same exposure as Keck. It’ll also have 4.2 times the resolution, meaning it will be able to separate out objects 1/4 the distance apart as Keck (so two stars that might be blurred together in a Keck image will be separated in the ELT image). It’s actually a bit more complicated than that, but you get the idea.

I don’t care how much it costs to build. Look at that thing! I hope they do it. That is just too cool.

A shining beacon to geeks everywhere

If über-geek Chris Pirillo can marry the funny, intelligent, and beautiful Ponzi, then there is hope for geeks, nerds, and dorks the world ’round.

Congrats Chris and Ponzi! Woohoo!

A vote for me is a vote against the eventual squid domination of the Earth

If you vote for PZ at Pharyngula, this will happen:

Won’t someone please think of the kittens?

Tip o’ the furry tentacle to Jim_MDP at the JREF board for the kitty picture.

The law versus religion

Note: NASA will attempt to launch the Shuttle again Saturday night at 20:47 Eastern time. There is only a 30% chance of the weather being good enough for launch, though. NASA successfully launch the Space Shuttle STS-116 into orbit tonight at 8:47 p.m. Eastern time, despite earlier worries that weather would delay it again. This was the first night launch in four years. On a personal note, only one TV station carried the launch in my area, and they cut off the segment 30 seconds after launch. Grrrrr. Now to your regularly scheduled BABlog post.

Take a look at this picture:

That image, from The Desert Sun, a Palm Springs newspaper, shows a 30-foot high aluminum cross loaded with 39 compact fluorescent light bulbs (13 Watts each). It sits on a hill high above Palm Desert (about 14 miles from Palm Springs), is owned by a local church, and can be seen for miles.

And therein lies the problem. The cross violates several local and state ordinances about light pollution. As the article points out, it is six times brighter than allowed for local Palm Desert law, and is too close to Mt. Palomar (home of the giant 200 inch telescope) — any bright lights within 45 miles of the venerable observatory are supposed to be shut off for most of the night. The cross, however, stays lit.

The article quotes some legal folks, who say this is complicated. I’m not so sure. The laws seem pretty clear. And there is more– the owners were supposed to get a permit to make any changes to the cross, but the old wooden one was replaced with the current aluminum one without such a permit. I suspect the bulbs fall under the category of needing a permit as well.

The irony here is that religion is messing up the situation, when it shouldn’t be. Here is one quotation:

Ron Garret, a professor of law and religion at the University of Southern California, points to federal law, the Religious Land Use and Institutionalized Persons Act of 2000, which bans state and local governments from discriminating against religious institutions in the application of zoning laws.

I don’t see it as discrimination to tell a church to turn down or turn off its lights which violate the law. In fact, it’s discrimination if they don’t, against anyone who is not a church who has bright lights.

The article quotes the church rector, who muddies the issue:

“The great genius of the founding of this country was to have a tolerance and open acceptance of all faiths,” said Certain. “It’s not an open acceptance of faith to say you have to hide your symbol.”

The phrase "apropos of nothing" comes to mind. Why?

The First Amendment does say that Congress shall make no law that prohibits the free exercising of religion, certainly. But that has limits. For example, if someone has a religion that says they must eat live kittens, how long do you think that would last? What the Constitution is saying, I think, is that no laws can be made against religion specifically. The church is in violation of general laws, to which it must remain bound. The rector can talk about faith all he likes — another First Amendment freedom — but it has nothing to do with this situation.

The problem isn’t about any show of faith, or religious freedoms, or whether a cross can be displayed (except for the permit violations, which I bet could be solved easily). The real problem is just with the lights. If the church simply turned down the lights there would be no issue.

Instead of tangling up legal and religious issues, maybe the church should go out and buy some dimmer bulbs.

I can’t imagine I’m the only one thinking clearly about this. Sometimes I think I’m taking crazy pills.

Tip o’ the mitre to Fark. And be ye fairly warned, says I: lots of silliness and purposely immature banter at that link.

Vote for me. No bones about it.

Is there no depth PZ won’t stoop to?

In his latest attempt to defame me, he tries to appeal to the "cute tentacles" crowd. But clearly this is really an attack on those of us with bones. By supporting the deviant nature of non-calcified animals, PZ is opening a gateway that can only lead to one horrible outcome.

That is why I am promoting the "Defense of Vertebrates Act". This legislation, which I will submit to the National Academy of Higher Mammals, states that affection, care, and declarations of " Awwwww, isn’t that cute!" can only be given to animals with bones (and to whatever animal goes into making McNuggets).

For quite some time, PZ’s votes for Best Science Blog of 2006 were… well, I was going to say neck-and-neck with mine, but invertebrates have no necks! How disgusting is that? Why would any red-blooded American — and do squid even have red blood? — vote for some slimy neckless nautiloid?

I have a neck. And I’m willing to stick it our for what I believe   for what I have faith in   that which I ascribe contingent trust.

Remember, PZ: Cephalopods cuttle and run, but vertebrates never do. Vote for Bad Astronomy and keep the cartilaginous horde at bay.

Dune Mars

I know, I’ve been posting a lot about Mars images lately, but I can’t help it. They’re so pretty!

But I think I have a favorite now. Check out this HiRISE image of Mars dunes:

Mmmmmmm. Prettttty. I love so much about this picture. The flowing shapes, geometric yet still smooth and somehow sensual, like a very expensive velvet fabric. The steel grey color and the tonal contrast washes over my eye. And then, of course, is the knowledge that these are wind-swept dunes of iron-laden sand, an aeolian deposit of alien dust upon an extraterrestrial surface.

Sigh.

Some art loses its integrity of you look too closely, but nature is still better at this than we are. Let your mind zoom down into the images, and see what details lurk therein:

There is fine rippling of the sand between the dunes, and the ridges still bear out their sharp contours. How lovely! And it does nothing to subtract from its beauty to know that at the time this images was taken, the ground temperature was something like -100 ℃.

And even this is not the sharpest image; there is a 13000 x 21000 (108 Mb) image of this as well on the HiRISE site. Remember– the smallest features you see in this image are a meter or two across.

Funny– meteorite geek that I am, the first thing I thought of when I saw this picture was how much it looked like a Sikhote-Alin meteorite, an iron meteorite that impacted in Russia in 1947:

The dunes have nothing to do with the meteorite, but the shapes in the image and the color are strikingly similar. Of course, the Mars image is grayscale, and the real color of the surface there is probably reddish or tan. But that’s OK, it takes nothing away from the picture’s beauty.

Sikhote-Alin is my favorite kind of meteorite, so this Mars picture has meaning for me that way as well. Now, I just have to let Mrs. BA let me make a print of it and hang it somewhere in the house, preferably next to my meteorite collection …
