Mirrors will save us

BBC NEWS | Mirrors 'could deflect' asteroids

The idea:

Flying mirrors could save earth from a catastrophic asteroid collision, researchers have claimed.

Up to 5,000 mirrors would be used to focus a beam of sunlight on to the asteroid, melting the rock and altering its orbital path away from earth....

"With only 10 spacecraft flying in formation, each with a 20m mirror, we could deflect a similar size asteroid into a safe orbit in about six months.

"Our studies show that this technology is genuinely feasible.

Um, for a big asteroid, controlling 5,000 mirrors on spacecraft is considered feasible? Just blow it up.

It's official

BBC NEWS | Middle East | Official Saudi website for fatwas

I only post about this because I like this term:
The situation at present, he said, was fatwa chaos, with Muslim scholars issuing rulings that clash with the official line of the religious establishment, spreading confusion.
Has a certain ring to it, don't you think?

If you can't say something nice, then... ah, forget it

I really wish a certain prominent blogger would stop posting pictures of himself.

Also, I have always thought his attempts at photo essays are terribly dull and indicate he has never read even a magazine article with suggestions on how to take an interesting photo.

(Look, if you can't be bitchy on your own barely read blog every now and again, where can you?)

Bjorn again, again

Bryan Appleyard meets Bjorn Lomborg - Times Online

This is an interview (well, more of profile really) with Bjorn Lomborg. He sounds an interesting character. (Turns out he is gay, which makes the way he upsets Greenies even more satisfying.)

A tale of the young and stupid

The ex files: Andrew Cottam, 27, and Hannah Claydon, 21

I don't know why people volunteer such disclosure about their unhappy past relationships, especially when it is a story like this one.

Andrew tells the story of how, as a 21 year old, he dated a 15 year old. He met her down at the local (underage drinking?) and describes her as:
...an opinionated, self-assured teenager with lots to say. I offered to walk her home and we shared our first kiss on the doorstep. I didn't have any reservations about the age gap because she seemed so mature.
It would seem that a sexual relationship started quickly, with the mature, self-assured 15 year old climbing up to his bedroom and leaving early the next morning. (His parents, having common sense, did not approve of the age difference, or perhaps it was also the fact that what he was doing was probably illegal.)

Of course, it all turned into a nightmare pretty soon when said self-assured girl, after 6 months, couldn't see her boyfriend every night because of work. She became "sulky and argumentative" and insanely jealous. Andrew finally had enough after this incident:
One night, I sneaked out when Hannah was asleep. I chatted to a group of lads in the bar, with no intention of meeting girls. Hannah woke up, realised I'd escaped and went mad. She stormed into the bar, pouring a drink over my head and slapping me in the face.
Relationship ends. How sad.

Of course, I am posting about it because it the blackly funny "told you so" aspect of it all. However, appearing as it does in the women's section of the Observer, I don't know that it will reach the audience to which it might serve as some sort of warning.

Strange science time

I mentioned recently that it seems that the creation of "naked singularities" (without the cloak of a black hole event horizon) at the Large Hadron Collider is considered a possibility. It seems that their creation via the same astrophysical process of gravitational collapse that leads to black holes is still being considered too.

This recent paper looks at the possibility that may account for some of the most powerfully energetic events in the universe. Here's some extracts:
Impulsive cosmic events combine two main puzzling features, namely an extremely short time of emission (order of a second) and a very high energy fluence. The main challenge therefore is to find a unique mechanism which allows at once for both properties.

The most impressive examples of the above type of events are the Gamma Ray Bursts. The total energy emitted can be as high as 1054 ergs, mostly concentrated in a pulse as short as a second. This amount of energy appears much more stunning if we think to it as being the energy emitted in a second-long pulse by 1010 galaxies each made of 1011 Sun-like stars, each emitting at a rate of ∼ 1033 ergs/sec., concentrated in a region probably smaller than a galactic core!
OK, I knew Gamma Ray Bursts were powerful, but that just sounds ridiculous. I wonder how far away from one you have to be in order to stand any chance of survival?

The paper goes on to explain that naked singularities comprise a Cosmic Time Machine, which, if I understand it correctly, can beam out huge amounts of energy from the the past and future. The author believes that these may account for some (all?) Gamma Ray Bursts.

Still, there seems to be a limit on how long the burst can last (luckily!):
Evidently the longer a naked singularity lasts as such the more luminous will be the burst because longer is the future development which will be ”compressed” by the time inversion and therefore more are the photons which will contribute to the prompt emission. This mechanism may lead to undesirable bursts of infinite intensity! Naked singularities however appear to prevent this circumstance. It is well established that a naked singularity decays to a black hole.
For the possibility of naked singularities being created right here on Earth, maybe late next year at the LHC, go see the paper extracted at my previous post here.

I presume that astrophysical naked singularities may be very, very different from the ones formed at the LHC, but as I said in my last post, it would be nice to see the possible consequences of having then in Europe clearly addressed.

The X ray bag

Found over at Red Ferret Journal, try taking this bag on board your next flight, especially if it's to the USA:


As the witty guy who writes for RFJ says:
The X-Ray Bag is guaranteed to raise a chuckle at the airport security line, oh yes. They’ll be laughing and smiling and pointing you out as a really interesting and funny person. Heck, they may even invite you home to meet the family when you get back from your trip. Or you’ve paid the bail money. Either way, it’s a wonderful way to meet people and make new friends.

A very unlucky person

Paintball Accident Made Him a Widower, and Then a Crusader - New York Times

In 2004, a husband and wife took their 10 year old son to a paintball park, but then this happened:
A 14-year-old player inadvertently detached a valve, launching his gun’s carbon-dioxide-filled cylinder as an unguided missile. It struck Ms. Contois, who was watching from a picnic area off the field, in the back of the head. She never regained consciousness, and died at the scene.
It is hard to credit just how unlucky she would have to be to die that way.

The Eddie Elephant in the Room (a TV rant)

So, Channel 9's new TV boss David Gyngell thinks that putting back Eddie McGuire into a super rich, super long, version of Who Wants to be a Millionaire is a good idea?

Funny, I seem to recall that when the show used to offer a paltry million bucks, it was dragged out from 60 to about 80 minutes most nights. A $5 million prize will likely mean a purported 80 minutes ends in 120 minutes. Why not just say it will be three hours then let it run right through to Today?

Although "Millionaire" maybe used to rate well enough, I have a general theory that Channel 9's problems really began when Eddie started appearing more on screen (not just when he tried his hand at management.)

I have always found him an unappealing screen personality who gives me the strong impression that he is likely a jerk in real life too. The impression was reinforced when I read in a review of "Who Killed Channel 9" that his sophisticated sense of humour included this:

When the producers walked into McGuire's office, according to Cress' diary, "Eddie is standing with his back to us, feet splayed apart and his hands firmly on the desk. 'From what I've heard about you guys, I guess I'm going to have to assume the position' ".

Cress comments: "I always suspect that someone who begins a business meeting trying to put you at ease with a man-joke is probably leading up to something less funny."

Anyway, everyone knows how Gyngell could revive Channel 9. Everyone.

Here's the new promo: Channel 9: The One that Won't Stuff You Around

Yes indeed, absolutely everyone knows that the crucial problem with most commercial television in Australia for the last, I don't know, 5 or more years, is that they decided to STUFF EVERYONE AROUND.

Do I need to spell it out? How many series are now run from episode 1 to even episode 10 without a 2, 3 or 4 week hiatus (possibly more than one,) during which there may or may not be old episodes from the same series 3 years ago, as well as at least one a change in the time-slot. (And that may be from sometime vaguely reasonable to something completely unreasonable.)

And how about this for another radical idea: programming will follow age appropriate times. I'm not talking MA shows after 8.30 pm either. No, the most astoundingly puzzling programming I have seen for years is the two English antique shows (Bargain Hunt and Antiques Roadshow) being shown on Nine between 5 and 6pm. What the hell? This doesn't count as a show with any conceivable general family interest: certainly it would send children running screaming from the room. Has Nine decided that it must help parents by running these moribund shows so as to convince primary schoolers they can then do their homework before dinner at 6? And the people in retirement villages who may want to watch it are probably in the dining room eating at 5.30 anyway.

All Gyngell has to do, apart from "boning" McGuire permanently, is to announce that, of all the commercial TV in Australia, Channel 9 will be the only one now to show series for a full, continuous season, with no weeks of interrupting repeats, and a guarantee of (at most, and only if it is truly deserved) one timeslot change per show per year.

(And Antiques Roadshow will not be shown, but a special DVD set will be send to the half dozen people who have been watching it.)

Car park terrorist

New Scientist Technology Blog: Hybrid cars: Too damned quiet?

The post above is about the issue of the potential danger of silent hybrid cars (well, at least until their petrol motor kicks in.) Should they make some sound when in electric mode?

I don't think this commenter was joking when she wrote this:
Personally, I find it great fun to drive around underground car parks in 'stealth' (electric only) mode, creeping up behind people with laden shopping trolleys and gaggles of screaming kiddies, and scaring them out of their wits.

On the open road I haven't hit any pedestrians - blind or otherwise - yet, but have nearly collected a couple of cyclists who didn't look, or signal, before changing lanes.

But seriously, I think education is the answer. Everyone, from littlies learning to cross the road, up has to learn to rely on their eyes and not just their ears. As for the blind - they should be able to feel the vibrations and hear the slight 'crunching' sound the tyres make on most paved surfaces. I've had to learn that pedestrians and cyclists aren't necessarily aware of my presence and are likely to try and throw themselves under my wheels.

Hitchens and a death in Iraq

A Death in the Family: Politics & Power: vanityfair.com

Christopher Hitchens writes very well about his dealings with the family of a young man killed in Iraq who had cited Hitchens as inspiring him to enlist.

Model

Recognize this?

The Japanese cartoon ran in Australia in the 70's. It's Space Cruiser Yamato, and this model was one of the fiddliest I've ever taken glue to. The boy is impressed, though.

Famous last words

Wild Thing: Books: The New Yorker

The oddest thing I learned from the above article about the (generally dislikeable) ballet dancer Rudolf Nureyev was that his last words were "Moby Dick". Not quite in the "Rosebud" league, is it?

Mark that one down for your next trivia competition.

Sounds interesting

How I faked it for the Nazis - Times Online

There's a movie on the way about a large scale Nazi counterfeiting operation. Sounds an interesting story, even if changed somewhat for the film.

He's right

Guardian Unlimited: God knows where all the religious novels went

Being quite the fan of Evelyn Waugh and CS Lewis, I agree.

As it happens, I have never tried Graham Greene, but will get around to him one day.

Yes, novels informed by a Catholic or quasi-Catholic sensibility are hard to come by these days.

Getting better

Sony Unveils Second Edition of Reader Digital Book

I don't think the first one was even released in Australia.

In any case, the features of this second version sound considerably improved.

Katz on Gillard (or so he wishes)

Rudd's right-hand woman is one foxy lady - Opinion - theage.com.au

I haven't recommended a Danny Katz column for a while, but this one is quite funny.

Update: I have noticed that, whenever I recommend a Danny Katz column, I seem to get quite a few visits from someone in Melbourne who is Googling his name. Does Mr Katz spend every Thursday searching for comments on his latest column? Not that there would be anything wrong with that, but if it's you, D Katz, just make a comment here, or send me a carton of wine as a reward for saying nice things about your writing. I probably increase your readership by at least 2 or 3!

A good point...

This link is to a post by Bryan Appleyard, which leads to his review of a book which claims to take a scientific approach to showing that something like a "soul" exists.

The book may be of interest, but I liked this first comment to the post, as it seems to me quite true:
One thing that intrigues and baffles me as a non-scientist observing this latest fad in materialist determinism is how enthusiastic, sanguine and comfortable modern "brights" have become with this stuff. Not so long ago, when guys like Sartre ruled the roost, atheistic materialism was supposed to be terrifying and only for the stalwart--remember all that stuff about having the near superhuman courage to stare into the abyss of nothingness? Now everybody seems to be having a big party scorning that scary old free will, and religion is positively terrifying.

More things I didn't know

BBC NEWS | Middle East | Volcano erupts on Red Sea island

Hey, it's quite an extensive list really (the things I don't know), but the fact that there are any volcanoes in the Red Sea could have been included until this story broke.

Having heard the report, I wondered whether anyone had ever speculated that volcanoes in that area might have something to do with some Old Testament stories.

And, of course, Google quickly reveals that someone has suggested it already. (Jeez, don't you hate how it's getting harder and harder to even imagine that you have had an original thought since the internet came along.)

Anyhow, Colin Humphreys has suggested that Mt Sinai was an active volcano at the time Moses was hanging around there. Go have a read of his few pages from Google books (at the last link) and see if it sounds credible. (I suppose we should be asking geologists too, but they might ruin an otherwise plausible idea.)

Hitchens on China

Burma's foul regime depends on Beijing.

Christopher Hitchens points out the number of bad regimes that China supports, and it's very many indeed:
Is there an initiative to save the un-massacred remains of the people of Darfur? It will be met by a Chinese veto. Does anyone care about Robert Mugabe treating his desperate population as if it belonged to him personally? China is always ready to help him out. Are the North Koreans starved and isolated so that a demented playboy can posture with nuclear weapons? Beijing will give the demented playboy a guarantee. How long can Southeast Asia bear the shame and misery of the Burmese junta? As long as the embrace of China persists. The identity of Tibet is being obliterated by the deliberate importation of Chinese settlers. Mahmoud Ahmadinejad, a man who claims even to know and determine the sex lives of his serfs (by the way, the very essence of totalitarianism), is armed and financed by China.
