Beautiful and useful
This beautiful thing has practical applications. Here are some examples:
Electronic devices
Ferrofluids are used to form liquid seals around the spinning drive shafts in hard disks. The rotating shaft is surrounded by magnets. A small amount of ferrofluid, placed in the gap between the magnet and the shaft, will be held in place by its attraction to the magnet. The fluid of magnetic particles forms a barrier which prevents debris from entering the interior of the hard drive.
Aerospace
NASA has experimented using ferrofluids in a closed loop as the basis for a spacecraft's attitude control system. A magnetic field is applied to a loop of ferrofluid to change the angular momentum and influence the rotation of the spacecraft.
Medicine
In medicine, ferrofluids are used as contrast agents for magnetic resonance imaging and can be used for cancer detection. The ferrofluids are in this case composed of iron oxide nanoparticles and called SPION, for "Superparamagnetic Iron Oxide Nanoparticles."
There is also much experimentation with the use of ferrofluids in an experimental cancer treatment called magnetic hyperthermia. It is based on the fact that a ferrofluid placed in an alternating magnetic field releases heat.

Be careful on the golf course
View_From_Here sent me this joke:
Two women were playing golf. One teed off and watched in horror as her ball headed directly toward a foursome of men playing the next hole...
The ball hit one of the men. He immediately clasped his hands together at his groin, fell to the ground and proceeded to roll around in agony. The woman rushed down to the man, and immediately began to apologize... "Please allow me to help. I'm a Physical Therapist and I know I could relieve your pain if you'd allow me," she told him.
"Oh, no, I'll be all right. I'll be fine in a few minutes," the man replied. He was in obvious agony, lying in the fetal position, still clasping his hands there at his groin. At her persistence, however, he finally allowed her to help. She gently took his hands away and laid them to the side, loosened his pants and put her hands inside. She administered tender and skillful massage for several long moments and asked, "How does that feel?"
"Feels great," he replied, "but I still think my thumb's broken!"
Thank you, View.

Quick thinking
Mrsgunka sent me this joke about two naughty ladies...
Two women were out for a Saturday stroll. One had a Doberman and the other, a Chihuahua. As they walked down the street, the one with the Doberman said to her friend, "Let's go over to that bar for a drink."
The lady with the Chihuahua said, "We can't go in there. We've got dogs with us."
The one with the Doberman said, "Just watch, and do as I do."
They walked over to the bar and the one with the Doberman put on a pair of dark glasses and started to walk in.
The bouncer at the door said, "Sorry, lady, no pets allowed."
The woman with the Doberman said, "You don't understand. This is my seeing-eye dog."
The bouncer said, "A Doberman?"
The woman said, "Yes, they're using them now. They're very good."
The bouncer said, "OK, come on in."
The lady with the Chihuahua thought that convincing him that a Chihuahua was a seeing-eye dog may be a bit more difficult, but thought,"What the heck," so she put on her dark glasses and started to walk in.
Once again the bouncer said, "Sorry, lady, no pets allowed."
The woman said, "You don't understand. This is my seeing-eye dog"
The bouncer said, "A Chihuahua?"
The woman with the Chihuahua said, "A Chihuahua? They gave me a damn Chihuahua?!"
Thank you, Mrsgunka.

Shameful
This nasty video is all over the internet. It may have not been filmed in Afghanistan, but what it depicts is very disturbing.
The BBC reports:
The US military has said it is investigating a video that appears to show a group of marines urinating on dead Taliban fighters.
The origin of the video is not known, nor is it clear who posted it online.
Marine Corps headquarters at the Pentagon said in a statement: "The actions portrayed are not consistent with our core values and are not indicative of the character of the Marines in our Corps. This matter will be fully investigated.''
These are some of the comments on the Liveleak website:
. Islam dictates that the body must be washed before burial - nothing wrong here, just helping out.
. It's "wet-down" time. Buy them lads a few beers so they can continue to piss all over the sand-monkies faces. If I was there I'd take a huge dump on one of those Taliban dude's heads. Hey, maggots gotta eat too!
. i'll bet it was cleaner than the water in that country.
. They should have shit on them first. Fuck the taliban, they are worth less than pig feed.
. They are dead. They don´t care.
. AWESOME!! Piss on those dead bastards!!!
. LOL! Final insult before they meet the maker and are cast to Hell with the rest of the MooSlimes.
. Excellent, well done lads, piss on them and what they stand for.
. They rolled up to the pearly gates expecting their 72 virgins and all they got was a stinky golden shower.
. HELL YEAH! done that to a grave but never on the body itself.. woohoo. must be awesome.
Whether the video is genuine or not, the fact that it has gone viral and has attracted these unkind comments doesn't do the US armed forces any good.

i-Laugh
Tumbleweed sent me this very funny story:
It all began with an iPhone...
March was when our son celebrated his 17th birthday, and we got him an iPhone. He just loved it. Who wouldn't?
I celebrated my birthday in July, and my wife made me very happy when she bought me an iPad.
Our daughter's birthday was in August so we got her an iPod Touch.
My wife celebrated her birthday in September so I got her an iRon.
What my wife failed to recognize is that the iRon can be integrated into the home network with the iWash, iCook and iClean.
This inevitably activates the iNag reminder service.
I should be out of the hospital next week!!!
Thank you, Tumbleweed.

Lost goat
MD sent me this. It's ingenious!
At a high school in Montana, a group of students played a prank... they let three goats loose inside the school.
But before turning them loose, they painted numbers on the sides of the goats:
1, 2, and 4.
School administrators spent most of the day looking for...
No. 3...

Comic book setting a good example for the real world
The Daily Mail reports:
The Life With Archie #16 issue due out on Wednesday features for the first time a same-sex wedding between characters Kevin Keller and partner Clay Walker.
After months of anticipation from fans of the comic book, readers will able to see soldier Kevin marry doctor Clay in front all their friends and family.
In the issue, Kevin has joined the army but is injured while serving a tour in Iraq.
While recovering from his injuries in a hospital rehabilitation unit, he meets Clay and they eventually fall in love.
Kevin is the series' first gay character and was introduced to the comic series in April 2010.
Last month, chief executive of Archie Comics Jonathan Goldwater told CNN Kevin was introduced 'to reflect what's going on with kids today in the real world'.
If only certain politicians made an effort to move into the 21st century as well...

Tony Blair, in a rush to hide his money and dodge taxes
This is from the Daily Mail:
Tony Blair's money-making has soared to unprecedented levels as official figures reveal his companies posted a bonanza 42 per cent rise in income last year.
The former Prime Minister's secretive business empire declared a £12million turnover, up from £8.5million the year before.
Yet this is potentially only the tip of the iceberg, since Mr Blair exploits a perfectly legal loophole to keep his finances secret.
The full extent of his income is cloaked in secrecy because he has constructed a complex web of shadowy companies and partnerships which let him avoid publishing full accounts detailing all the money from his commercial ventures.
The £12million turnover was posted by Windrush Ventures, one of at least 12 companies and partnerships controlled by Mr Blair, already thought to have channelled tens of millions of pounds through his various firms since leaving Downing Street in June 2007.
But the company posted an administrative cost of nearly £10.2million to another company owned by Mr Blair, leaving him with a profit of just over £1million.
With the corporate tax rate of 28 per cent, this left Mr Blair with a tax liability of just £315,000.
Money cascades through the interlinked Windrush firms, which have been described by accountants as an 'opaque' business model which shields the true amount of money being paid to Mr Blair.
Accounts filed at Companies House yesterday revealed that £10.2million of the £12million income from Windrush Ventures Ltd was paid into it from Windrush Ventures No 2.
Income for Windrush Ventures No 1 and Windrush Ventures No 2 is not disclosed in their accounts, and there are no accounts at all for Windrush Ventures No 3 because it is a limited partnership and not required to file accounts.
Mr Blair has set up a mirror-image to the Windrush structure of four companies called Firerush Ventures.
The nature of business undertaken by the Firerush companies has never been disclosed - though limited partnership Firerush Ventures No 3 has been permitted to conduct business by City regulator the Financial Servcies Authority - suggesting a money managing activity.
Mr Blair's astonishing earnings include lucrative after-dinner speaking, consultancies with banks and foreign governments, a series of deals with foreign companies, and the pension and other perks he enjoys as a former Prime Minister - including taxpayer-funded police protection.
Critics also point out that a large proportion of his earnings comes from patrons in America and the Middle East - a clear benefit from forging a close alliance with George Bush during his invasion of Iraq.
What next? Is he going to create water and earth rush ventures to hide money from the wind and fire?
I can't forgive Tony Blair for turning the Labour Party into a gateway to his money-making ventures. I can't forgive him for taking Britain into an illegal war and making a profit from it. He's a narcissistic money grubbing con artist with a big, smug smile on his face. Sounds familiar?

Equal opportunities
Back in the 90's I worked for social services in Surrey, an affluent area in the south of England. My job was to register and inspect childminders and playgroups. Childminders look after children in their own homes and playgroups offer informal educational opportunities for under 5s.
Part of the registration process involved attending a course on the various aspects of working with young children. The course covered several topics, such as food hygiene, play, the business side of childminding/running a playgroup, safety precautions, behaviour management and equal opportunities. I led the sessions on the last two topics.
This post is about equal opportunities, inclusion and challenging stereotypes regarding race, gender and disabilities.
Race was a tricky subject to explore in a predominantly white area. The sessions about it were always very heated. "Why should I have black dolls and books showing people of other races if all the children I look after are white?" they asked. "Why should I have to spend money buying ethnic toy foods and cooking implements if none of the children eat any of those things?"
Why indeed...
It was a lot easier to discuss these things in some other areas of the country, where the population comprised a varied mix of people from different cultures. It was easier to find positive and negative examples within a more diverse community. In Surrey, it seemed that these "other people" only existed in exotic locations, far, far away.
Advertising in those days reinforced this notion. Ethnic minorities were shown in ads for vacations or when charities appealed for money to help some famine stricken country. Apart from that, they didn't seem to exist. Ethnic minorities living in Britain didn't need mortgages, didn't buy insurance, food, clothes, toys, didn't have bank accounts, telephones, household appliances... What came across from their complete absence from ads about everyday life was that they should be seen as no more than a colourful backdrop for white people's vacations, dancing in their lovely typical garments, riding camels and elephants.... or pulling some charitable heartstrings, starving, with their bones protuding, their children covered in flies.
Things have improved in the past twenty years. Most toy shops now sell black dolls and books have improved, but other resources are still lacking. Ads these days generally reflect the cultural and ethnic mix of the British population. Children growing up in Surrey won't have the surprise of their lives when they move away from the area and see people with different colour skins, doing everyday stuff, just like themselves.
In the area of disability, however, things didn't move very far. Children and adults with disabilties still inhabit the world of charity. Advertising is a good reflection of the attitudes towards any segment of society. Disabled people don't need financial services, don't buy clothes, don't eat at fast food restaurants. They only appear in the commercial breaks when they're needy. Toys and books that move towards inclusion are not available outside specialist outlets. When dolls with Down syndrome and other disabilities became available in the UK, they caused controversy. Some parents objected to their children's disabilities being highlighted and made into an object of fun. I beg to differ. The idea behind such toys is to combat the invisibility of people with disabilities and to give children with special needs opportunities to identify and relate to dolls like them, developing a sense of self. I believe it also helps able bodied children to see disabilty as part of life, not something hidden, "over there," much like the ethnic minorities I discussed earlier.
Unfortunately, even when there are attempts at integrating children with special needs into UK mainstream schools, most of the time the schools miss the mark. They provide a special needs assistant and that's it. I have observed many children with Down syndrome who had assistants in the classroom. The teacher interacted with the rest of the pupils, the assistant alone interacted with the child and s/he wasn't involved in any of the activities, didn't work with the other children, didn't play with them. There were no classroom resources to help integration or identification. Paying lip service to integration by having a disabled child in the classroom who remains isolated and who interacts only with a glorified babysitter does nothing for the disabled child or for the able bodied children.
As for gender stereotypes, my research led me to the websites of some very popular toy retailers. The first category in their search boxes is "search by gender." I selected "boys" from the drop menu and had pages of construction toys, cars, train sets, firefighters' and policemen's outfits. Then I selected "girls" and was greeted by dizzying pink pages of dolls, cooking stuff, hairdressing kits, make-up sets, nurses' and fairies' outfits. Our little friend Riley had a good rant about it in a video I posted a few days ago...
What prompted me to write this long post was the inclusion of Ryan, a six-year-old model with Down syndrome, in the Nordstrom and Target catalogues. Without fanfare. He was just another child in group of children wearing nice clothes, visible and included.
I believe that providing the right resources in play and educational settings and increasing the visibility of minorities in everyday activities would go a long way in creating a more inclusive society. Ethnic minorities would no longer be seen as distant and exotic. People with disabilities would no longer be seen as strange, uncomfortable or simply needy.
Marketing forces seem to dictate how products are presented. Ethnicity and disability rank lower in the scale than the gender divide. Ironically, in these days of gender equality, it seems to be the most difficult stereotype to tackle...

Kiribati
Marakei Island in the Island Country of Kiribati near the Equator in the Pacific is a small atoll with an emerald green lagoon. The airplane dance tells the story of the WW II Invasion of their island. Dancers imitate the frigate bird in their style. Dancers often entrance themselves, and must maintain composure throughout the dance. This specific dance and style is only seen on the small island of Marakei.
I like the presidential residence. No frills and no false grandeur...
I was quite busy with other things today and didn't have time for a proper "trip" to Kiribati. I couldn't find any decent recipes, but will keep looking. Maybe some other time...
