A remarkably warm winter temperature

Climate Central notes that much of the US has had little snow this winter, and some of the Plains states have just had some very high temperatures:

The National Weather Service said on its Sioux Falls, S.D., website that one sign pointing to the unusual nature of the warm weather was the fact that old records were exceeded by huge margins, as much as 17 degrees warmer than previous records, the agency's website states. As noted by the Weather Channel's Twitter account, the high temperature of 61°F in Minot, N.D., — an all-time January record — was the average high temperature in April, according to The Weather Channel.

Mass prostate cancer screening doesn't reduce deaths: study

This seems pretty strong reason to not worry about PSA testing, but I bet it won't be accepted quickly.

Not dead yet

Tiger set to boost services

Tiger Airways (the airline that's somewhat akin to a flying Soup Nazi, except it's the price that's good, not the quality) is still alive and expanding a bit.

I want them to survive. I should use them again in the next year.

Very kind of them...

Soft drink vending machines offer free Wi-Fi Internet access ‹ Japan Today

Asahi Soft Drinks Co has developed a vending machine that provides free Wi-Fi connection to the Internet.

The company said on its website that 1,000 Wi-Fi vending machines will be rolled out this month in Tokyo, Sendai, the Chubu and Kinki regions, as well as Fukuoka. It said it plans to expand the number to 10,000 within five years.

The free Internet service, to be provided in association with Freemobile, will be available in two types, Asahi said. One will require registration via email, and one will not. Asahi says both services will be free of charge.

Asahi says that sessions will time out after 30 minutes and that wireless hotspots will available within a 50-meter radius of Asahi vending machines. WPA2-PSK security will be provided.

The electrodes must be tiny...

Scientists record electrical currents that control male fertility

Biologists Yuriy Kirichok and Polina Lishko of the University of California, San Francisco, have made a name for themselves recording the electrical currents that course through, yes, cells....

In a pivotal study, the husband-and-wife team has uncovered how progesterone - a hormone involved in menstruation and - switches on a sperm's internal electricity. The electric current kicks sperm tails into overdrive, powering the final push toward the egg. Sperm that fail to heed progesterone's "get-up-and-go" signal could help explain some couples' struggles to conceive, say Kirichok and Lishko, both Ukrainian immigrants.

Humans and algae

I've found that American Scientist seems to put a fair few of its feature articles on its website.  Here are a couple of some interest:

*  the potential for algae based biofuel is discussed in some detail here.
*  the question of whether homo sapiens' "modern" behaviours evolved over tens of thousands of years is discussed in this article

I should add this magazine to the blogroll soon.

Mochi deaths noted - 2012

It's time for me to note the annual New Year's mochi death toll from Japan.

(Look, this blog is high on Google search for only a few things:  Julia Gillard's enormous earlobes, forehead mites, and mochi deaths.   I have to keep going to maintain my pathetic numbers...)

Anyway, as with last year, it seems the English language media from Japan is slow to report this now, and I have to resort to Google searching in Japanese.

So far, I've come up with this, courtesy of Google translate, from Yomiuri Online:
The number of people were transported by ambulance to the New Year mochi choking is 3:00 pm daily, up to 13 people in Tokyo alone, two of whom died.

According to the Tokyo Fire Department, around noon on December 28, men in Nerima (82), died 草餅 clog. Noon to 30 men Hino (101) died of suffocation by clogging clots lunch.
I have had this confirmed:  yes, the story says the two who died were 82 and 101!  (I wonder who fed mochi - famous for causing choking in the aged) to the 101 year old. 

And looking that the searches in Japanese, that is all I can confirm so far.

This job is getting harder by the year....

I'll check for more reports tomorrow.

Update:  collected figures for the nation remain as evasive as ever.  Ah well.  Japan has had enough death within the last year without worrying about this.

Still Kant-ing after all these years

I mentioned before that I had picked up a copy of Philosophy Now for some holiday reading, mainly because Ï felt I just had to reward whoever it was that came up with the cover featuring this:  "Kant & Co.   Kant, Hegel, Nietzsche, Schopenhauer - Four Dudes that Shook the World".

As it turns out, I didn't find the story on Kant all that good, although it did point out that the famous problem of what his system of morality means for lying (he thought you shouldn't even lie to an axe murderer who arrives at your door looking for your occupant) is about a conflict of values, and Kant didn't talk about this at all.

The relevant section from the article is this:
Staying with the axe murderer, it should be plain that more than one imperative/moral principle is relevant to the situation.  Certainly we should tell the truth; but do we not also have an obligation to fight evil?  We are confronted with a conflict of values here.  Unfortunately, as far as I know, there is no explicit discussion of this issue in Kant.  One could assume, however, that his general approach of distinguishing the lesser from the greater evil should be applied.  I think Kant might say that although lying is never right, it might be the lesser evil in some cases.

What the writer (Prof Peter Rickman, a former head of philosophy at City University in London) is that the murderer example came up during Kant's life and he did try to address in an essay.  If this summary from Wikipedia is any guide, Rickman's optimism about Kant coming up with a "lesser of two evils"resolution seems ill placed:
This challenge occurred while Kant was still alive, and his response was the essay On a Supposed Right to Tell Lies from Benevolent Motives (sometimes translated On a Supposed Right to Lie because of Philanthropic Concerns). In this reply, Kant agreed with Constant's inference, that from Kant's premises one must infer a moral duty not to lie to a murderer.

Kant denied that such an inference indicates any weakness in his premises: not lying to the murderer is required because moral actions do not derive their worth from the expected consequences. He claimed that because lying to the murderer would treat him as a mere means to another end, the lie denies the rationality of another person, and therefore denies the possibility of there being free rational action at all. This lie results in a contradiction in conceivability and therefore the lie is in conflict with duty.

I also note that in what can be argued is a sign that philosophy is either:

a. a lively, relevant and engaging activity relevant to the modern world; or
b. stuck in endless and unproductive repetition and should be replaced with more drinking

you can Google the topic "Kant and conflict of categorical imperatives" and get 225,000 links, including to this one, from a discussion in 2011 which is pretty good. The modern issue of lying to the axe murderer at the door is usually reformulated to the more historically relevant "what should good Europeans have done if they were hiding Jews in their house and a Nazi came to the door asking awkward questions". The "best" answer to the question in that last link notes that strict Kantian thought would deny there really was a conflict; the lying can never be justified. It also points out that Kant would argue that the truthful house owner would not be morally responsible for the deaths of the Jews, which is technically true but no doubt hardly a source of comfort to most people. But the other interesting point is that Neo Kantians have another way out of the specifically Nazi based example:
It's also worth considering that a neo-Kantian would take issue with your example on technical level, arguing that it's not a good example because the Holocaust is an exceptional situation, a special case, if you will. More specifically, the German state at the time formed an illegitimate government, and the SS officers were acting as agents of this illegitimate government, this state that is on face unjust. Given such case, one could argue, his entire corpus of ethics does not apply, as it was only intended to apply to situations involving a just government. (For more on this, see Kant's "Doctrine of Right" and Metaphysics of Morals 6:264, etc.)
That's not helpful if a real revenge seeking violent person comes to your door looking for your relative, however. The last link also provides a link to a philosophy journal discussion of the issue from Nov 2010, which looks interesting indeed, but is behind a paywall.  Here's what we can see, from the part of the abstract that is available:

 Sorry about the fuzzy quality of the image: I did my best.

The author of the article is Helga Varden, an assistant professor of philosophy at the University of Illinois, and her list of work indicates she's quite the Kant fan.   I see she has one paper entitled "A Kantian Conception of Rightful Sexual Relations," which sounds like a blast from a man who thought masturbation was more degrading than committing suicide.

Anyhow, it's interesting to note how Kantian philosophy continues to intrigue and be debated after all these years.  The motivation, I suppose, comes down to wanting to ground morality and ethics on something rational other than utilitarianism, which has its own distinct problems (which, incidentally, get discussed in an article in the same issue of Philosophy Now about the "trolley problem".)    

Back to normal programming soon...

A short history of drinking on New Year's

Why we get wasted on New Year's

Salon has a fun look at why drinking and New Year's go hand in hand. Here's a key paragraph:
Across ancient Europe, the yuletide holidays were a free-for-all, made dicey by role reversals: The poor invaded the homes of the rich, men dressed as women, and the lord bowed to the peasant. The 12 days of Christmas, from Dec. 25 to Jan. 7, were set in the mold of the Roman holiday Saturnalia: The holidays were a period of truce, when old grudges should be forgotten (at least temporarily), and anger swallowed. But despite all this brotherly love, the Christmas season had a sinister playfulness, similar to the original concept of trick-or-treating. Echoing Saturnalia’s public ridicule of society’s laws and customs, rowdy bands of peasants invaded the manor, demanding food and drink. In exchange, the lord received his subjects’ blessings and goodwill for the coming year.
It's unfortunate that we can only manage fun for about 8 or 9 days, in this modern world. However, if you had money, you probably would tire of "wassailing"pretty quickly:
By the 17th century wassailing was a holiday tradition. Girls gussied up in holiday finery would carry a dubious alcoholic punch (usually spiced beer with apples) from door to door. The wealthy were expected to drink a toast and offer the wassailers payment in return. Far from the beatific carolers of today, the mobs were known to get unruly: Wassailers would prank or menace householders who refused them booze or money.
After noting that Puritans did not approve of this festive season, we at least can be thankful that we do not have to watch our national leaders emulate the Sumerians:
Mather no doubt was equally horrified by New Year’s Eve, which always marked an apex of drunken revelry. This is true around the world and throughout time: Although the New Year is celebrated from June to January and from Tallahassee to Timbuktu, almost all cultures have used the passing of one year to the next as an excuse to really party. Take for instance the fine old Sumerian tradition wherein the king had public sex with the high priestess of Ishtar, symbolizing the conception of Ninkasi, the goddess of beer.

A deep and meaningful end to 2011

Hegel and Hegel's God - The Philosopher's Zone - ABC Radio National (Australian Broadcasting Corporation)

I read an article in Philosophy Now by Robert Wallace about Hegel's idea of God, and found it pretty interesting. He was in Australia last year and did an interview with Alan Saunders on the Philosopher's Zone, and it covers the same material.

I found it rather interesting, but you must read it all.

At GOMA today

It was time to make another school holiday visit to the Gallery of Modern Art today.  It's hard to dislike modern art when it's in such a nice building.  Some highlights included a exhibit by a Japanese avant garde artist who's infatuated with dots (I think I had heard of her before), and some Aboriginal dogs from North Queensland.   I'll just post the photos to give you an idea:




If ever you are in Brisbane, you must visit it.

Green Philosophy by Roger Scruton – review | Books | The Guardian

Here's a somewhat cynical, but nonetheless interesting, review of Roger Scruton's new book on his version of being Green.

You have to read it to understand the title of the post.

Here comes the AP1000

New Toshiba reactor model gets U.S. nod | The Japan Times Online

I meant to post about this before Christmas, but forgot:
The U.S. Nuclear Regulatory Commission has approved Toshiba Corp.'s AP1000 reactor design, paving the way for the first new reactor construction license to be issued in more than 30 years.

The five-member agency voted unanimously Thursday in favor of certifying the reactor's design.Southern Co. and Scana Corp. are seeking permission to use the next-generation reactors to expand nuclear power output at existing sites in Georgia and South Carolina. The certification "marks an important milestone toward constructing the first U.S. nuclear reactors in three decades," Energy Secretary Steven Chu said Thursday in a statement.
Well, they certainly take their time with new reactor approvals. As the report goes on to note:
The biggest difference between the AP1000 and existing reactors is its safety systems, including a massive water tank on top of its cylindrical concrete-and-steel shielding building. In case of an accident, water would flow down and cool the steel container that holds critical parts of the reactor — including its hot, radioactive nuclear fuel.
An NRC taskforce examining the Fukushima nuclear crisis said licensing for the AP1000 should go forward because it would be better equipped to deal with a prolonged loss of power — the problem that doomed the Fukushima No. 1 plant.
Good to see better passive safety being considered so important in new designs, but I would assume you could better than having a water tank on top.

Anyway, you can have a detailed look at the design at the reactor's own Westinghouse/Toshiba website. It's full of reassuring statements like this:

The AP1000® pressurized water reactor works on the simple concept that, in the event of a design-basis accident (such as a coolant pipe break), the plant is designed to achieve and maintain safe shutdown condition without any operator action and without the need for ac power or pumps. Instead of relying on active components such as diesel generators and pumps, the AP1000 relies on the natural forces of gravity, natural circulation and compressed gases to keep the core and containment from overheating. However, many active components are included in the AP1000, but are designated as non safety-related.
Multiple levels of defense for accident mitigation are provided, resulting in extremely low core-damage probabilities while minimizing occurrences of containment flooding, pressurization and heat-up.
The AP1000 meets the U.S. NRC deterministic-safety and probabilistic-risk criteria with large margins. Results of the Probabilistic Risk Assessment (PRA) show a very low core damage frequency (CDF) that is 1/100 of the CDF of currently operating plants and 1/20 of the maximum CDF deemed acceptable for new, advanced reactor designs.
I hope they are right.

From The Guardian

The Guardian may have helped caused the closure of the News of the World by reporting some policeman's wrong theory about how voicemails came to be deleted from a murder victim's phone, and been in bed with Julian Assange until it decided he really was only in it for himself and filed for a divorce,  but I still find it one of the best newspaper websites around.   Take these items from its Comment is Free section, for example:

*  Stephen Kelly, a freelance journalist who still seems to like really big glasses, writes about the deification of Dr Who, which did become a key feature of the show under Russell T Davies, and continues under Steven Moffat.  He writes:
The Doctor, of course, isn't marketed outright as a messianic figure but it's all there: "the lonely god", more of an idea than a man, who resurrects himself in a crucifix position; who has, literally, defeated the devil, resisted temptation and forgiven his greatest enemy; "he's like fire and ice and rage", it was once said. "He's like the night and the storm in the heart of the sun. He's ancient and forever. He burns at the centre of time and can see the turn of the universe. And … he's wonderful."

Even the main premise of the show is built upon the concept of existential salvation: the idea that one day this wonderful being will drop out of the sky to rescue us from the crippling tedium of adult life, to make us believe that there is more to existence than work, bills and over-thinking popular tea-time television shows.
All quite true, but it has really started to weigh the show down.

Denis Alexander (a British biologist and Christian) has a short but pretty good attempt at reconciling Genesis with evolution and atonement through Christ.  Here's the key passage:
The tradition of interpreting the early chapters of Genesis figuratively – as a theological essay, not as science – goes back to two great thinkers from Alexandria: the first-century Jewish philosopher Philo, and the third-century church father Origen. In 248 Origen wrote that Genesis references to Adam are "not so much of one particular individual as of the whole human race". Figurative understandings of the Genesis text have been part of mainstream theology ever since.

The first mention of Adam in the Bible is clearly referring to humankind (Genesis 1:26-27) and the definite article in front of Adam in chapters 2 and 3 – "the man" – suggests a representative man, because in Hebrew the definite article is not used for personal names, with Eve being the representative woman.

The Genesis narrative tells the story of humankind going their way rather than God's way. On the day that Adam and Eve sin, they do not drop dead but proceed to have a big family, albeit now alienated from friendship with God, causing spiritual death. Nowhere does the Bible teach that physical death originates with the sin of Adam, nor that sin is inherited from Adam, as Augustine maintained. But the New Testament does teach that humankind stays true to type – all people sin by their own free will – and Christ dies for the sins of all. Christ is the second Adam who opens up the way back to friendship with God through his sacrifice for sin on the cross. The result is the "at-one-ment" that the first Adam – Everyman – is unable to accomplish by his own efforts.
I'm not sure I'm entirely convinced, but it seems this is a summary of an argument he puts in an entire book on the subject, and it may be worth the effort.

*  On a lighter note, kind of, a writer looks at the latest report of Japanese retreat from relationships, and brought to my attention this story from earlier in the year:
Virtual girlfriends became a sensation last summer, when Japanese game-maker Konami released its second-generation of its popular Love Plus, called, aptly, Love Plus +, for the Nintendo DS gaming system. Konami skillfully arranged for an otherwise deadbeat beach resort town called Atami to host a Love Plus + holiday weekend. Players were invited to tote their virtual girlfriends, via the gaming console, to the actual resort town to cavort for a weekend in romantic bliss. The promotion was absurdly successful, with local resort operators reporting that it was their best weekend in decades.
He ends on this point:
"Maybe we're just advanced human beings," says a Japanese friend of mine over dinner this week in Tokyo, who won't let me use her real name. She is an attractive, 40-something editor at one of Japan's premier fashion magazines, and she is still single. "Maybe," she adds, "we've learned how to service ourselves."
Seriously, if research leads to more advanced ways for men to derive more, ahem, pleasure from virtual interactions with their electronic girlfriends, Japan is over with faster than even currently anticipated.

The comments following the article, from (I assume) mainly English people complaining about the difficulties in relationships indicate that the Japanese may just be a bit ahead of the curve.

*  Finally, the marvellously named Morven Crumlish talks about the Scottish celebration of Hogmanay (the New Year party which is, apparently, pretty full on in the drinking and fighting.

Interestingly, I see that they share the Japanese idea of cleaning up the house for the New Year.

But in comments, there are many people of Scottish heritage who say they are over the whole thing.  I liked this one:
Once you get out into the rural areas hogmanay is more community based with first-footing and the meeting up with friends. But in the big cities it has lost its main meaning. The Edinburgh hogmanay parties are just ugly vulgar spectacles packed out with interlopers and freaks, whereas in the west of Scotland the neds and radge use it has an excuse to act out the Battle of Helms Deep from the Lord of the Rings using tonic wine bottles has props. If memory serves the A&E departments in the West of Scotland at hogmanay and new years days are swamped with an insane amount of stab victims in the 18-24 demographic.

For once i think Glasgow council done the right thing this year by stopping the paid celebrations in George Square. theres a lot of people who are on the poverty line and cant afford a big swanky doo at Hogmanay. If anything the first-footing tradition of the lump of coal and mini bottle of grouse carries more symbolism than any amount of drunk hussies on Princes street.
Call me ignorant, but I can't say I've heard of "first-footing" before, so here we go:
"First footing" (that is, the "first foot" in the house after midnight) is still common in Scotland. To ensure good luck for the house, the first foot should be male, dark (believed to be a throwback to the Viking days when blond strangers arriving on your doorstep meant trouble) and should bring symbolic coal, shortbread, salt, black bun and whisky. These days, however, whisky and perhaps shortbread are the only items still prevalent (and available).
 The website I got that from goes on to explain some ever odder old Scottish New Year's traditions:

The traditional New Year ceremony of yesteryear would involve people dressing up in the hides of cattle and running around the village being hit by sticks. The festivities would also include the lighting of bonfires, rolling blazing tar barrels down the hill and tossing torches. Animal hide was also wrapped around sticks and ignited which produced a smoke that was believed to be very effective to ward off evil spirits. The smoking stick was also known as a Hogmanay.

Some of these customs do continue, especially in the small, older communities in the Highlands and Islands of Scotland where tradition, along with language and dialect are kept alive and well. On the Isle of Lewis, in the Outer Hebrides, the young boys form themselves into opposing bands, the leader of each wears a sheep skin, while a member carries a sack. The bands move through the village from house to house reciting a Gaelic rhyme. On being invited inside, the leader walks clockwise around the fire, while everyone hits the skin with sticks. The boys would be given some bannocks - fruit buns - for their sack before moving on to the next house.

OK.  I think we've all learnt something today.  Unless, of course, you are smarter and better read than me.

Chlorine and spirits - a ramble around Spring Hill

As it looked as if a storm might be on the way this afternoon, and the normal Council pools are not good places to be when lightning is around, I took the kids to the Spring Hill Baths in Brisbane today.

I hadn't been there for nearly 30 years, I reckon.  Built in 1886 and (seemingly) not changed much since, it's a good little bit of history tucked away in the inner Brisbane suburb which I have always liked.  Here's a photo of the interior, with the changing booths lined around the perimeter.  You can't see the "women only this side" and "men must not loiter at the end of the pool" warning signs, but they are there:


That photo, incidentally, is courtesy of a rather distinctive looking fashion blog, presumably run by a Brisbane woman.  Not my cup of tea, but worth a quick look.

Now that I look at other, older photos, I see that it has changed quite a bit inside:


The photo is from 1910, and one suspects that life preservers were necessary at pools at the time due to women being pulled under by the weight of their wet bathing suits.

More about the history of the pool is found at the Queensland Heritage website, and I see it did have a very practical aspect:
Constructed for the Corporation of Brisbane in 1886 at a cost of £2,526, the Spring Hill Municipal Baths provided the city with its first inground public baths. They replaced in popularity the older floating baths in the Brisbane River, and provided an important hygiene/sanitation facility in Spring Hill....

On the evening of 9 December 1886 and amid great ceremony, the baths were opened by the Mayor of Brisbane, James Hipwood, who took the first plunge.

One of the principal reasons for establishing the Torrington (Arthur) Street bath was its location above the Spring Hollow (Water Street) drain, installed in 1884, the waste water from the baths providing a daily cleanse. River water from Petrie's Bight was pumped to a small reservoir at the top end of Albert Street, then gravity fed down Spring Hill to the Hollow, where it was stored in holding tanks (now boarded over) at the far end of the baths. Each evening the pool was drained and every morning the water was replenished in a process lasting several hours. This system of flushing the Spring Hill drain was employed for three-quarters of a century. Not until 1914 did the city council install a salt water supply scheme to which the baths were linked. As the Brisbane River grew more polluted, chemicals were added to the pool water, and finally a filtration system was installed in 1961.
Interestingly, when you look at the history of swimming pools at Wikipedia, it seems pools only really started being built in England around the late 1830's, with swimming clubs taking off about 30 years later.  Brisbane was relatively quick to get into the act.

The pool was also socially advanced: the Queensland Heritage article I linked to before notes that in 1927 it was one of the first pools in Australia to allow mixed bathing.

Given the age of the pool, it did get me thinking about when they might have started chlorinating it.  As you can see from the above extract about its history, the answer is not readily available; but then again, when did any pools start getting chlorinated?  The answer has not been so easy to find.

According to a brief article from America (which, incidentally, notes that the first American swimming pool was built in 1887 -  a year after the Spring Hill Baths opened):
....the first attempt to sterilize a pool in the United States using chlorine was at Brown University in 1910.  The 70,000-gallon Colgate Hoyt Pool was chlorinated by graduate student John Wymond Miller Bunker.
But it doesn't then go on to explain when it started being used more widely.  It does note, though, that:
Prior to the introduction of sterilization technologies most swimming pools were filtered to keep them somewhat clean and the water was changed frequently.
Given that the Spring Hill Baths were used as a daily iant flush of the Spring Hollow drain, this is obviously the way it was kept partially clean.

Oh, here we go:  I've found the full length article on the history of chlorination in pools that my earlier link only summarised:  it would appear that in the US, chlorination was introduced commercially in the 1920's, and by 1930, most high school pools used chlorine in one form or another.

So there's another small gap in my knowledge filled.

Anyway, after the swim and an ice cream, I took the kids down the road to the Spring Hill Spiritual Church.  Why would I do that?   Well, because (as mentioned at this very blog in 2006, but you probably weren't paying close attention), Sir Arthur Conan Doyle visited it in 1921.  I was hoping that the plaque recording this was on the outside of the Church, but it doesn't seem to be.  Oh well.

I can't find any photo of his visit either.  The best I can come up with of his trip to Brisbane is a photo of him visiting a Goodna bee farm.    The John Oxley Library blog entry on the visit notes that not only was Brisbane pretty fast at building a bathing pool, it had some surprisingly early enthusiasts for spiritualism too:

In closing Conan Doyle observed that he’d been told he could expect only “one person” at his Brisbane lectures.  In fact the city had a strong core of devotees and one of Conan Doyle’s special honours during his visit was to lay the foundation stone for the Brisbane Spiritualist Church. Already in the early 1880s a weekly magazine The Australian Spiritualist was being published in Brisbane and there were practitioners like the daughters of German-born musician Professor A. Seal who recorded musical scripts transmitted to them by their father from the grave.
This reminds me:  I think it was on a tour of the Noosa River many years ago, that I heard there was a historic house on it which was famous for its owners being heavily into spiritualism.

Oh.  It would appear to be on the island that Richard Branson built his mini resort.   Maybe it's haunted.

So, that's it for now.  I was going to mention my long time admiration of the Queensland Transport building at Spring Hill, but that will have to wait for another day.

Safer, cleaner, nicer

We have drift off: Balloons to the edge of space - New Scientist

New Scientist looks at a Spanish company that is actively developing civilian flights in helium balloons that would take the joyriders 34 km high before descending in on a guided parachute:

There is no doubt that it is possible, because it has been done many times before. In the 1950s and 1960s, more than a dozen crewed balloons journeyed to near-space. In 1957, for instance, Joe Kittinger of the US air force ascended to a height of 29 kilometres in a capsule attached to a helium balloon. He enjoyed the ride so much that when ordered to descend, he replied: "Come and get me."

Zero2Infinity hopes to spread that joy to the civilian population. The company has carried out several test flights of uncrewed balloons, and earlier this year got the funding needed to carry out its first flight carrying people.

The plan is to use a massive helium "bloon", as the company likes to call it, to carry a pressurised capsule with space for two pilots and two passengers up to 34 kilometres above the Earth. You can book now - but at €110,000 per ticket, you'll need a little spare cash.

Sure sounds like a safer option than Virgin's joyrides, which I predict is a business that will go defunct as soon as a fatality occurs.

The New Scientist article also points out that one study indicates that the Virgin rocket (which has particularly dirty exhaust) could have very adverse effects indeed:

All rockets inject pollutants directly into the stratosphere, which has various effects. In particular, hydrocarbon-fuelled rockets, such as the kerosene-powered Soyuz, produce a lot of soot, which warms the planet by absorbing the sun's heat. While soot in the lower atmosphere usually rains out after days, it can remain in the stratosphere for a decade or more, massively amplifying its effect. In 2010, Martin Ross and his colleagues at The Aerospace Corporation, a non-profit institution based in El Segundo, California, modelled the effect of 1000 sub-orbital launches each year with a rubber-burning engine like that of Virgin Galactic's SpaceShipTwo. The study concluded that the climatic effect of this kind of space tourism could be on a par with that of all commercial aeroplane flights put together.
Why hasn't this very anti-Green aspects of Richard Branson's vanity project ever had more publicity?

Japanese Jesus

Behold! Christ's grave in Shingo, Aomori Prefecture | The Japan Times Online

The Japan Times article on the (alleged) Japanese tomb of Christ is worth looking at, if only to see the road sign in Shingo pointing the way.

Kind of Christmas-y

Evolution of Angels: From Disembodied Minds to Winged Guardians

I see National Geographic had a story about angels for this Christmas, but it's a pretty quick overview that concentrates on Christian ideas of angels. This part reminded me of CS Lewis' Screwtape Letters:
Of course not all angels are angelic, according to some Christian traditions. Satan himself, it's been said, was once an angel named Lucifer.

The fact that angels can fall from grace is an important point, Catholic University's Root said—it implies that they have free will.

"You even had some theologians in the medieval and the early modern periods who thought that there was an adversarial angel, a fallen angel, assigned to each person as well as a guardian angel—though this was never an official thought," Root said.

The next part is also a bit novel to me:

As early as the second and third centuries, Christian scholars such as Origen of Alexandria saw important roles for fallen angels, Notre Dame's Cavadini said.

"For Origen and a lot of church fathers, angels participated in the governance of the universe at God's will," Cavadini said.

"That also meant that the fallen angels were intended to participate in the betterment of the universe, and that you have to take them very seriously, because they still did participate—but in a negative way."

Jewish ideas of angels don't get a mention, but I see Wikipedia gives a brief outline.
