Cyberchondriacs
Much like hypochondriacs who obsess about any small ache or pain they may have, cybercondriacs frequently surf the internet to glean information about anything that affects them. They now form 84% of all adult net users.
The term could also refer to people who imagine they have a disease because their symptoms match those on a health website.

What is the Stolen Generation?
* It refers to the aboriginal children of Australia who were removed from their families between 1910 and 1970 to be raised in white households.
* Australia followed this assimilation policy during that period. Now Prime Minister Kevin Rudd had delivered a public apology from its Parliament to the aborigines. For this historic session, he had invited their leaders and they have participated heartily.
* Australia gained independence from Britain in 1901. But it retained Queen Elizabeth as its head of State. It is the Governor General who represents the Queen in Australia. At present it is Mr. Michael Jeffery who is the Governor General.

The world's largest bolometer camera
The world's largest bolometer camera for sub-millimetre astronomy has been put into service at the 12-m APEX telescope, located on the 5100m high Chajnantor plateau in the Chilean Andes.
LArge BOlometer Camera (LABOCA) was specifically designed for the study of extremely cold astronomical objects

Casimir force
It is the ultimate cause of the friction in the Nanoworld in particular in some micro-electrom-chanical systems.
this force normally causes objects to stick together by quantum force .It can be reversed in vaccum ,where objects start repelling each other.
By manipulating Casimir force the performance of everyday devices ,from car airbags to computer chips can improve.

What is Balck Swan?
* It is a term used to describe the stock market collapse. It was coined by Nassim Nicholas Taleb in his book “The Black Swan” to describe a large-impact, hard-to-predict and rare event beyond the realm of normal expectations.
Advanced Kalashnikovs to be manufactured in India
Kalashnikov 100, an advanced version of the AK-47 assault rifle used by security forces and terrorists alike with ease, will be manufactured in India by an undisclosed company under license from the parent company--IZHMASH OJSC. The undisclosed Indian company, in which the Centre has majority stake, is in negotiations with IZHMASH and details were being finalised, Mr Alexander A Zavarzin, Foreign Economic Activity Director of IZHMASH told reporters.
Mr Zavarzin, whose company is participating in the ongoing Defexpo here, said the new version of Kalasnikov would be an advanced series with a plastic handle instead of the wooden one which will be three times stronger than a wooden handle.
It will also be much lighter than the original version and will have a night vision arrangement. It will also have less recoil. Mr Zavarzin said he had visited many states and met several police chiefs and officials trying to persuade them to equip their forces with the upgraded Kalashnikovs.

Australia named world's 3rd best country for university education
A survey of overseas pupils has projected Australia as the third best country in the world in terms of university education.
As many as 11,000 prospective students from 143 countries participated in the survey.
The surveyors found that after Britain and the US, Australia was the third preferred study destination among the subjects.

Hagiography
It is the body of literature describing the lives and veneration of the Christian saints. The literature of hagiography embraces acts of the martyrs (i.e., accounts of their trials and deaths); biographies of saintly monks, bishops, princes, or virgins; and accounts of miracles connected with saints' tombs, relics, icons, or statues.
Hagiographies have been written from the 2nd century AD to instruct and edify readers and glorify the saints. In the Middle Ages it was customary to read aloud at divine office and in the monastic refectory (dining hall) biographies of the principal saints on their feast days. Besides biographies of single saints, other works of hagiography told the stories of a class of saints, such as Eusebius of Caesarea's account of the martyrs of Palestine (4th century AD) and Pope Gregory I the Great's Dialogues, a collection of stories about Saint Benedict and other 6th-century Latin monks. Perhaps the most important hagiographic collection is the Legenda aurea (Golden Legend) of Jacobus de Voragine in the 13th century. Modern critical hagiography began in 17th-century Flanders with the Jesuit ecclesiastic Jean Bolland and his successors, who became known as Bollandists.
The importance of hagiography derives from the vital role that the veneration of the saints played throughout medieval civilization in both eastern and western Christendom. Second, this literature preserves much valuable information not only about religious beliefs and customs but also about daily life, institutions, and events in historical periods for which other evidence is either imprecise or nonexistent.
The hagiographer has a threefold task: to collect all the material relevant to each particular saint, to edit the documents according to the best methods of textual criticism, and to interpret the evidence by using literary, historical, and any other pertinent criteria.

OXML and ODF format
* Microsoft developed the former format – Open eXtensible Markup Language – as a standard for sharing documents. There is a competing standard which is promoted by Sun Microsystems, IBM, Red Hat and others. This is called the ODF – Open Document Format. The adoption of either of these as an ISO standard is crucial for each camp. The ISO is slated to discuss the issue in Geneva later this month.
* So, both the camps are trying their best to get India vote for their document format. The Indian option is going to be for ODF, as things stand today. The BIS (Bureau of Indian Standards) has raised about 82 technical issues against the OXML standard.

WiTricity
* It is wireless electricity.
* The key technology behind this is to make the recharding device and
the device that needs power to resonate at the same frequency. This
allows them to exchange power efficiently.
* The power source is kept at a distance of 2 meters from the bulb in
this experiment.
* The word `witricity' was coined back in 2005.
* Witricity exploits the coupling between electromagnetic resonant
objects to transfer energy wirelessly between them.

A logical fact
Q.)Why muslims (hujaj) revolve anticlockwise in Haj (Tawaf)??
Ans.) In physics there is a right hand rule for detecting the flow of
current,by using this rule if we curl the fingers in the direction
of motion of people, the thumb point towards the sky....that is towards
Allah.
