The universe may be watching, but we are listening.

A friend of mine posted this picture of the Glowing Eye nebula (gacked from APOD) in the constellation of Aquila, taken by the Hubble telescope. It’s clear that the universe is watching.

However, we are peering just as deeply into the void, and now moreso than ever.

According to the Miami Herald,  the Atacama Large Millimeter Array, better known as ALMA, is by far the largest radio telescope on earth. Interestingly, despite their size, the dishes are portable. Engineers transported them around the plateau on two giant flat-bed trucks. What the telescope picks up depends on where the antenna are positioned. Click to the Herald article for more details.

Seeing the Universe in Perspective

Escala de tamaños Sistema Solar

This image is a lovely digital representation of our solar system, with planets and orbits to scale. We look rather insignificant on that third rock from the left.

However.

Have a look at this image, comparing our sun to other stars in the galaxy: (click the image for full resolution)

Notice that in order to get VY Canis Majoris in the picture, our sun shows up as a single pixel. They’re not just whistling dixie when they say “supergiant”.

Thanks to blogger inhadowz, I can also point you to the following video, which animates the scale very nicely:

The scale of things in our universe is awe-inspiring.

Planned Obsolescence

plannedobsolescence

It’s a conspiracy, right? We all know that cars, computers, printer cartridges, lightbulbs, and other consumables are now designed to fail sooner than they have to, in order to get us to buy more.

Well, wait just a minute.

I ripped this comment by redditor Fenwick23 in its entirety, because it’s the best analysis of the “planned obsolescence” issue I’ve ever read. I’ve only bowdlerized it a little, and corrected a couple of spelling issues.

I grow weary of this repeated conspiratorial usage of the phrase “planned obsolescence”. They would have you believe that there are engineers out there designing products with the intent of causing them to break down sooner. Ridiculous. People just don’t understand how competition in manufacturing has shaped consumer product design. One of the oft-cited examples is the venerable Hewlett-Packard LaserJet printer. Back in the early 90’s if you bought a low-end HP laser printer, you got a printer built like a tank. The damn things were slow, but they never wore out. Contrast with the low-end now, which are flimsy, come with 3/4 empty toner cartridges, and certainly won’t be functional in 10 years. “Planned obsolescence”, the conspiracy theorists conclude smugly. But wait… how much did you pay for that LaserJet 4 in 1993? Yeah, it was over $2000… in 1993 dollars. How much did that lousy HP P1600 printer you’re complaining about cost? Yeah, it was $200. If you spend the equivalent of two grand in 1993 dollars, which is over $3000 today, you get something like the HP M575c , which prints, copies, and faxes in color, and it’s built like a tank.

What people don’t realize is that in the “good old days” of a given product, a cheap version simply did not exist, so all products of that kind of that vintage were well built. This happens in every industry, at various rates. Engineers are under constant pressure to reduce manufacturing costs to widen the consumer base. Those $200 printers sell at far more than 10x the rate of $2000 printers, because every college freshman is buying one. To that end, certain parts must by necessity be less durable. Ikea isn’t making bookshelves out of particle board to sell more bookshelves when they break, they’re using particle board because not enough people can afford $500 oak book shelves to keep all those Ikea stores in business. (emphasis mine)

“But Fenwick23”, you ask, “What about that inkjet printer that had an expiration date coded into the inkjet cartridges?” Well, that one’s sadly all too easy to explain. Engineers, under the aforementioned pressure to cut costs, came up with a way to make inkjet systems for much cheaper. The only trade-off was that they had limited useful life before the ink dried out and clogged the nozzles. No big deal, just add an expiration system to the all-in-one nozzle-head-ink-tank package that lets the customer know that they need to buy a new one. This design is so much cheaper than the old design, they won’t mind buying it more often. But as so often happens in big corporations run by non-engineers, between the engineering department and the store shelves some upper-middle-manager looked at these cheaper ink jet cartridges and said “WOW WE CAN MAKE MOR PROFITZ IF WE SELL THEM SAME PRICE AS THE OLD KIND!” As a result, the anticipated reasonable trade-off intended by the engineers disappeared in a puff of pointy-haired logic, and six months later HP is stuck with a PR nightmare that looked like planned/programmed obsolescence, but which was in reality the result of managerial idiocy.

There are, of course, some real examples of planned obsolescence. The canonical example, from which the phrase was popularized, was Brooks Stevens use of it to describe 1950’s automotive marketing strategy. Brooks wasn’t talking about the cars breaking down, though. He was talking about aggressively marketing styling changes. The idea was to make last years model seem obsolete by changing the body designs. In essence, Brooks’ notion of planned obsolescence was nothing more than adopting the same strategy as the high fashion clothing industry. Sure, your car and your jacket work fine, but don’t you know that this year the cool people have wider lapels and round taillights?

The one place where planned obsolescence is a conspiracy to make you throw away perfectly serviceable items and buy new ones in order to prop up an industry is college textbooks. Renumbering pages and shifting end of chapter questions around is exactly the sort of sinister behavior people accuse HP of. The reasons educational publishers stoop to such tactics is quite clear, though. Their customer base is not expandable by making the product cheaper, so in order to maintain profits they have to make their otherwise durable product “expire” somehow. It’s evil, but understandable.

I applaud people repairing serviceable goods. Heck, I make a living repairing broken things. I just get sick of idiot “journalists” from places like Wired parroting the tired notion that the obsolescence of products in our cheap consumer society is the result of sinister motives, rather than the fact that we’re all bloody cheapskates.

Thank you, Fenwick23.

Elliðaey, Iceland

houseonisland

This picture showed up on Reddit with the title “Because fuck everybody,” and after I stopped laughing, it piqued my curiosity.

As it turns out, this is the island of Elliðaey (63° 28’05.10″ N, 20° 10’31.98″ W), the third largest island of the Westman Islands, located south of Iceland. The island is a mere 0.18 mi² in area and is uninhabited. From this website, we learn the following information (translation is mine, so it’s imperfect but gives the gist):

“On the island is a large fishing house owned by the Ellidagrim Islands Society, which engages in puffin egg hunting in summer and in spring. In earlier times there was a hunting lodge called simply “dwelling.” The first building which was built on the island still stands. It is used for storage, and is west of the ‘Skápana.’[1] In 1953, a new lodge was built at the foot of Hábarð (the highest peak on Elliðaey)  because the old building failed the test of time. In 1985, work began on a new two-story fishing house which was attached to the house that was built in 1953; it was completed in 1987. In 1994 it was discovered that the 1953 edifice had deteriorated to such an extent that it was no longer useable. It was therefore demolished and another house built instead in the same location, with construction being completed in 1996. Between 2000-2001, a small house west of the lodge was built, which houses the Ellidagrim Islands Society sauna.”

A recent picture showing the 1996 lodge, and the small sauna finished in 2001.

There’s a lot of misinformation out there about this island, chief among which is that Iceland gave Elliðaey to the singer Björk as a royalty payment for her services to the nation.

From “The Independent”, 2-10-2000:


THE ICELANDIC singer Björk may have put her nation on the map, but plans to grant her exclusive use of an uninhabited island off the west coast to reward her for her services have run into difficulties.

Earlier this week David Oddsson, Prime Minister, told parliament: “Björk has done more for the popularity of Iceland than most other Icelanders. My view is that she may be given the use of this island [Ellidaey] as a royalty payment, as recognition from the state.” But, amid an uproar in the country, the government has had to reconsider its generosity. Yesterday Mr Oddsson’s office denied Ellidaey had been sold or leased to the singer. If sold, said a spokesman, it would be only to the highest bidder. Icelandic radio reported rumours that the musician was no longer interested in the island. She has neither confirmed nor denied reports and was not available for comment yesterday. Despite her much-professed love for Iceland, Björk is neither based there full-time nor does she sing in Icelandic.


Notice that the Independent article says “off the west coast.” The confusion arose because  there is another island with the name of Elliðaey to the west of Iceland (65° 8′ 42.86″ N, 22° 47′ 10.99″ W), just north of Stykkishólmur,

Ellidaey2

which is most likely the one referred to by the Prime Minister in his abortive but generous gesture. Mr. Oddsson thought it would be a nice idea, but local protests deep-sixed the plan. As for the island of Elliðaey to the south, the one with the hunting lodge, it was never associated with Björk in any way.

Never heard it expressed quite so eloquently. I am a person of faith and I have my own spiritual walk, but public schools must teach empirical science, and only empirical science. What religious parties are attempting to do with public school curricula (i.e. teaching that evolution is only a theory, or promoting intelligent design) defies all logic.
