If the great wall of china started from your city?

Now you must shocked reading this. But what can i do, that is true now. It's possible by BBC it's map. BBC has launched new setvice or can say function in which you can overlap the great wall of china on your city as making your starting point. This is for you to exactly know how big is that place where you are going to go or about that you are thinking. This service is already launched by BBC. I have posted too many articles on Google's new service with its growing business. But this is the best innovative idea of Google I feel ever.

 this is the greag innovative idea of BBC's advanced engeneer gets in their genious mind. for that you can choose any place as example your city and overlap the place where you want to know how big is it? So, that you can know exactly how big is that place. I hope in this function it will be available to overlap your city to the place where you want. you will never know if you see only any place in your map. but to compare there when ever you lap on your knowing area you can know how bug is it?

Dimensions takes important places, events and things, and overlays them onto a map of where you are.

Dimensions is an experimental prototype for the BBC. We want to bring home the human scale of events and places in history. The D-Day landing beaches measured from London to Norfolk in the UK. How far would the Titanic stretch down your street?

Dimensions simply juxtaposes the size of historical events with your home and neighbourhood, overlaying important places, events and things on a satellite view of where you live. Certain "Dimensions" can be transformed into short walks, so you can get a physical appreciation of the distances involved.

Type in your postcode or a place name to get started. That's the really great thing for us and for technology developing at every 45 seconds.

How to measure a website's IQ?

The creator of the world wide web, Tim Berners-Lee, has made an odd request: for a kind of rating system to help people distinguish sites that can be trusted to tell the truth, and those that can't.

Berners-Lee was speaking at the launch of the World Wide Web Foundation, which aims to ensure that everyone in the world benefits as the web evolves.

In his speech he referred to the way fears that the LHC could destroy the worldspread like wildfire online. As the BBC puts it, he explained that "there needed to be new systems that would give websites a label for trustworthiness once they had been proved reliable sources."

He went on to say that he didn't think "a simple number like an IQ rating" is a good idea: "I'd be interested in different organisations labelling websites in different ways". Whatever process is used to hand out the labels, it sounds like a bad idea to me.

Berners-Lee himself directed us towards some of the its biggest problems:

"On the web the thinking of cults can spread very rapidly and suddenly a cult which was 12 people who had some deep personal issues suddenly find a formula which is very believable...A sort of conspiracy theory of sorts and which you can imagine spreading to thousands of people and being deeply damaging."

There are plenty of arguments online already about whether Scientology is a cult. I find it unlikely anyone will be keen to step in and label sites on either side as not to be trusted. Others might reasonably argue that all religions - whether established or not - should come with a warning message.
As for wading in to put a stop to conspiracy theories, I can't image anything their proponents could benefit from more.

Berners-Lee also mentioned the system would help people find out the real science behind, for example, the LHC's risks. You might think handing out rating for sites about science would be easier, with publishers of peer-reviewed science, for example, receiving a top rating without problems.

But there will be papers in the archives of any journal that have been entirely superseded. And a whole lot more that present results that are valid, but can be misleading to some readers. Web licences to ensure that people only read sites they can handle are the next logical step.

Fortunately it's much more likely that the whole idea will quietly be forgotten, which will at least prevent Berners-Lee receiving one of the first "potentially misleading" badges for thinking it up in the first place.

Let's hope the World Wide Web Foundation and its laudable goals have a rosier future.

Now Black Holes Can Be Reproduce in Laboratory

Black Holes have always fascinated scientist due to their mysterious properties, but there is much to be learned about them. These strange regions once thought to be absent of light before research found that actually these are the regions with such an extreme gravitational force that nothing, not even light can escape from their surface.

ccording to a latest invention Black Holes (imitation of Black Hole actually) can be reproduce in laboratory now!

Black Holes: What are

they?

Let’s understand it through the example of our own earth:

The mass of earth creates the gravity the pulls the things towards it. With enough power we can escape the earth’s gravitational force. This is how space vehicles leave the earth’s atmosphere.

Now if we squeeze the size of earth to that of a marble. This will increase the mass and gravitational force of earth to such extent that it would be impossible to bypass that force. Black holes are also regions with such a large mass and gravitational force that not even light can escape from them. Due to this it is not possible to view Black holes, but their presence can be realized only by the nearby activities.

Till now scientist have done extensive research about these strange regions in the universe. We know how they born, where they occur, and why they exists in different sizes, but there is much to know about them.

How to Know More about Black Holes?:

Dartmouth researchers have now proposed a new way to explore Black Holes. They plan to reproduce the black hole at a smaller scale in laboratory.  A paper has been published in this regard in Physical Review Letters, August 20 issue.

This method of creating tiny black holes of quantum size will help scientist to understand the insights of Black holes. Stephen Hawking, eminent space scientist had proposed that, Black Holes are not totally void of activity and they emit radiations in the form of photon. This radiation is known as Hawking Radiation or Bekenstein-Hawking radiation.

According to Paul Nation, a co-author of paper and Dartmouth graduate student,

“Hawking famously showed that black holes radiate energy according to a thermal spectrum. His calculations relied on assumptions about the physics of ultra-high energies and quantum gravity. Because we can’t yet take measurements from real black holes, we need a way to recreate this phenomenon in the lab in order to study it, to validate it.”

Scientist has shown that how a magnetic field-pulse microwave transmission line containing an array of superconducting quantum interference devices can reproduce physics analogous to a radiating black hole. This system can be controlled in laboratory and quantum mechanics properties. They can also manipulate the strength of applied magnetic field.

Past Attempts in this Field:

Creation of Black Holes in Laboratory has been proposed before by scientists. It has been proposed using supersonic fluid flows, ultracold bose-einstein condensates and nonlinear fiber optic cables. But the main problem in these schemes was weak Hawking radiation or masked radiation due to overheating of device. This latest scheme is much more efficient than previous proposed models.

SWALLOWING DIAMONDS COULD FIND WHAT'S AILING YOU

THE GIST

• Swallowing nanodiamonds could someday to help diagnose disease.
• Plain nanodiamonds coat the digestive tract, coated nanodiamonds could target other organs and tissues.
• Nanodiamonds have been proven to be nontoxic and safe in animal tests.   

Scientists from Taiwan have developed nanodiamonds that, when swallowed, harmlessly coat the digestive track. When coated with special sugars or proteins, the nanodiamonds are absorbed into the body and attach themselves to specific cells.

The research, which is currently limited to animals, could eventually diagnose and eventually treat diseases in humans.

"This research work demonstrates that nanodiamonds are non-toxic in both cellular and organismic levels," said Yi-Chun Wu, a scientist who, along with Huan-Cheng Chang and their colleagues in Taiwan, co-authored a new study in the journalACS Nano Letters.

Nanodiamonds are tiny pieces of pure carbon only a few of nanometers across. (One nanometer is about 100,000 times smaller than a human hair.) Most nanodiamonds are formed by blowing up TNT or other explosives to create high temperate and high pressures that bond carbon atoms together in a classic 3D diamond nanostructure.

These nanodiamonds are not solid, however. Inside those tiny structures are tiny holes, called vacancies, where a nitrogen atom from the air has replaced two carbon atoms. Nitrogen vacancies in diamonds are common. Natural diamonds with lots of nitrogen have a yellow tint to them. The nanodiamonds the scientists from Taiwan used absorb yellow light and emit violet light.

Next, the scientists fed two types of nanodiamonds to the round worm C. elegans. The first batch of nanodiamonds were uncoated, just pure carbon with a few nitrogen atoms. Those nanodiamonds coated the digestive tract of the transparent roundworm.

The second batch of nanodiaonds the roundworms ate were coated with a special sugar. Once inside the roundworm, the nanodiamonds passed through the digestive tract and into the body of the worm, congregating at various points inside the body.

Both the coated and uncoated nanodiamonds glowed purple when yellow light was shined onto the roundworms, revealing their location inside the worm. All the bejeweled worms had normal lifespans, and none of them showed any sign of distress, said the scientists.

The scientists fed the nanodiamonds to the worms just to measure their toxicity and to see where the diamonds ended up. More specific functions will come soon though, said Vadym Mochalin, a scientist at Drexel University who uses nanodiamonds in his own research.

Virtually any kind of protein or chemical can coat nanodiamonds. When placed into the body, those coated nanodiamonds could seek out and attach themselves to cancer cells, immune cells, pathogens and other cells.

At first, coated and glowing nanodiamonds will likely help doctors and scientists find and map cancers and other things that harm humans. After that nanodiamonds will likely be used to deliver low doses of powerful drugs to help treat those diseases.

Some researchers are most excited about using nanodiamonds to track stem cells.

"One of the most exciting applications of [fluorescent nanodiamonds] in humans is the long-term imaging, tracking, and sorting of human stem cells," said Chang.

Those stem cells could jump-start immune responses, help repair nerve damage, and potentially even regenerate entire organs if the research pans out. Those kinds of advanced therapies are still years, if not decades away however, caution scientists. But this research, along with dozens of other papers and groups working with nanodiamonds, opens the door for powerful therapies in the future.

"The nanodiamond looks very promising compared with other carbon-based nanoparticles," said Mochalin. "It's the least toxic carbon-based nanomaterial to date."

 

sony's show for latest gadget with new technology :Sony Expo Showcases Latest Tech

The annual Sony Hawaii Expo was held this week at the Ala Moana Hotel Hibiscus

 Ballroom.    Highlight of this year’s Sony Expo was the desktop Sony OLED flatscreen TV (shown above). The hallmark of this high tech wonder is its small size and crystal clear high definition picture. The screen itself is thinner than a compact disc jewel case.

Another hyped product at the Sony Hawaii Expo is the new Sony Rolly MP3 player. It is a new portable device that is shaped like a little barrel and moves to the beat of the music. The speakers on this device are positioned at both ends and open up with winglike flaps on each end. The device will not be marketed in the U.S. and is aimed only at consumers in Japan. If it were sold in the U.S. the price would be at around $400.

The Sony Rolly MP3 player. Sold only in Japan.

Face recognition “smile” technology for Sony Cybershot cameras were also a new this year. The new Cybershots can sense when a person smiles and fires only at that time. People were happily smiling for the demo at the Sony Cybershot booth. There were many other Cybershot digital still and video cameras that were also on display for consumers to play with.

I was most interested in the small super zoom, SLR-like cameras that I may want to get in an effort to find a capable SLR-like digital camera without all of the weight and bulk.

Last year’s hot product, the Sony Playstation 3 was almost like a has-been this year. Yes, there were displays of the venerable Playstation 3 for people to use, but the crowds around those stations were not very big. Sony is still marketing the Playstation 2 which is still the most popular game console of all time, despite Nintendo running away with the market lead on their new generation Wii product.

I am still interested in perhaps getting a Sony PSP, mainly for the fact that it can surf the web with its wireless internet feature. Another wifi device that was touted last year, the Sony Mylo, was nowhere to be seen this year. Sony still sells the device.

HDTV are the big products Sony is pushing this year as the Expo was dominated by flatscreen high definition sets all over the place. Going hand in hand with that were several Sony Blu-Ray HDTV DVD players. the pictures on the sets and from the players are incredibly clear.

People clamor around the latest Sony digital cameras.

Don’t know if I am ready to sink money in either of these technologies, especially Blu-Ray since it is locked in a format war with the rival HD-DVD. Beta vs. VHS all over again. I’ll wait for the dust to settle on this one.

Overall the Sony Expo was a great little venue to check the latest technology from one of the most popular electronic companies on the face of the earth.

NASA with space telescope !!

How Real Satellites/Space Telescopes Come About
A December 2007 artist's conception of the James Webb Space Telescope.Credit: NASA › Larger imageIt takes years to bring a real large space telescope from basic concept to hardware reality. First, a scientist comes up with an idea to study some aspect of the Earth or the cosmos. The idea is discussed, reviewed and developed by committees of scientists. It is proposed to NASA, who makes decisions on what missions to go forth on, and which missions to pass on. If a mission is selected for study a timeline is created to develop the mission.

One of the most difficult aspects of creating a new mission is convincing others to fund it. Once a mission is funded, the team of scientists and engineers "pitching" the mission can then investigate how it could come together. Later, NASA usually selects a prime contractor to help design the telescope and other systems that will fly on the satellite. Northrop Grumman was selected to build components for the Webb telescope. The instruments, or cameras, on the telescope are selected as well, with teams of scientists to watch over the design.

The design process usually includes a number of different designs, which are all tested to see which would yield the best result for the type of object the instrument would study. For example, various types of infrared cameras may be developed and tested, and the one that gives a scientist the best result, would be chosen to be built as a test unit.
Engineering Test Units
The life-sized James Webb Space Telescope model sits in front of the Royal Hospital Kilmainham, in Dublin, Ireland.Credit: Richard Bent, Northrop Grumman Space Technology › Larger imageEngineering test units, or ETUs are created before an actual instrument is built, so that engineers and scientists can make sure it would work properly. ETUs are a replica of the flight unit that can perform certain flight functions for testing purposes. ETUs are also used when engineers are practicing installation of an instrument into a satellite's mainframe or "bus." The outcome of the tests on ETUs may lead to a change in handling procedures of the actual flight instrument, but not a change in its flight construction.

Once the ETUs test successful, then the actual instruments that will fly aboard a satellite or space telescope can be manufactured. Those instruments go through their own set of rigorous tests by the manufacturing contractor, NASA and other partners. On the Webb telescope, NASA is partnering with the European Space Agency and the Canadian Space Agency.
Testing the System

Satellite and space telescope instruments can endure harsh temperature swings as big as 200 degrees Fahrenheit, micro-meteor impacts and exposure to solar radiation. On top of that, before a spacecraft like the Webb can operate in orbit, it has to survive a ride on a rocket to get there. That's where environmental testing chambers like the ones at NASA's Goddard Space Flight Center in Greenbelt, Md., come into play. Hardware gets run through NASA Goddard's centrifuge, acoustics and thermal vacuum chambers to ensure they can endure the rigors of launch.

The centrifuge simulates the increased feeling of gravity's pull during a launch. For astronauts, that's normally a few minutes at two or three times the force of Earth's gravity, measured in Gs. The Webb telescope can experience 6-7 G's due to the Ariane 5 rocket's combined acceleration and vibration. The Webb telescope will be launched on an Ariane 5 ECA rocket. The launch vehicle is part of the European contribution to the mission.

Launching a rocket carrying a satellite or space telescope creates extraordinarily loud noise, so engineers use an Acoustic Test Chamber to make sure an instrument can handle it safely. In Goddard's 42-foot-tall chamber, technicians expose payloads to the noise of a launch. To do that, they rely on 6-foot-tall speakers. The speakers (more accurately called horns) use an altering flow of gaseous nitrogen to produce a sound level as high as 143 decibels for one-minute tests. That's about the level of sound heard standing next to a jet engine during takeoff.

The hardware is also tested in the thermal vacuum which exposes them to conditions they will experience in space. The chamber has massive mechanical vacuum pumps and cryopumps to ensure that the hard vacuum of space is simulated in the test chamber. The cryopumps use gaseous helium to condense remaining gases out of the chamber once the mechanical pumps have done their work. The two types of pumps work together to eliminate all but the tiniest trace of air in the chamber, down to about a billionth of Earth's normal atmospheric pressure.

Because the Webb telescope is operating in the infrared portion of the electromagnetic spectrum it is designed to operate at very cold temperatures. To simulate this environment an additional cooling system, a helium refrigeration system, was added so the thermal vacuum chamber could reach temperatures in the -413 Fahrenheit (F) range. "The ISIM structure was tested in our thermal vacuum chamber down to about 26 Kelvin, or minus 413 F," said Jon F. Lawrence, Webb telescope Mechanical Systems Lead Engineer/Launch Vehicle Liaison at NASA Goddard.

This test program starts at the lowest level of assembly, instrument or spacecraft components and is repeated at each next level of assembly. Once the instruments pass these tests they are all put together into the structure which holds them and the unit is tested again. The instrument structure is connected to the telescope and the whole observatory is tested yet again. There isn't a vacuum chamber large enough to hold the entire Webb observatory at NASA Goddard, so the telescope will travel to NASA's Johnson Space Center in Houston, Texas, to be tested in a chamber that was originally built for testing the Apollo command module to simulate the trip to the moon. The next stop after that is launch into deep space.

Currently, ETUs or actual flight hardware for the Webb telescope are being tested in various ways.

The James Webb Space Telescope is the next-generation premier space observatory, exploring deep space phenomena from distant galaxies to nearby planets and stars. The Webb Telescope will give scientists clues about the formation of the universe and the evolution of our own solar system, from the first light after the Big Bang to the formation of star systems capable of supporting life on planets like Earth.

The Webb Telescope project is managed at NASA's Goddard Space Flight Center in Greenbelt, Md. The telescope is a joint project of NASA, the European Space Agency and the Canadian Space Agency.

Cruise Ships - Oasis Class (Oasis of the Seas)

The Oasis class (formerly known as Project Genesis) is a class of Royal Caribbean International cruise ships that are the world's largest passenger ships. Two ships were ordered in February 2006, named Oasis of the Seas and Allure of the Seas. Oasis of the Seas was completed and delivered on October 28, 2009, while Allure of the Seas is under construction and is expected to be completed by late 2010.

General Characteristics

Tonnage:	225,282 GT
Length:	360 m (1,181 ft)
Beam:	47 m (154 ft) waterline 60.5 m (236 ft) extreme
Draft:	9,3 m (31 ft)
Capacity:	5,400 passengers double occupancy; 6,296 total

The Oasis class have surpassed the earlier Freedom class as the world's largest passenger ships. At 360 m (1,180 feet) in length Oasis is 21 metres (69 ft) longer than the prior largest passenger ship, the Independence of the Seas and classmates. Oasis also is 8.5 metres (28 ft) wider, and with a gross tonnage of 225,282, is almost 45% larger. Oasis class vessels carry over 5,400 passengers.

Like the Freedom class, the Oasis class ships are built by STX Europe (formerly Aker Yards) in Turku, Finland. The first of the Oasis class, priced at US$1.24 billion (€ 900 million) reportedly is the most expensive commercial ship ever built. The option for a second ship of the class was exercised by Royal Caribbean on April 2, 2007. The second ship is to be delivered by STX Europe in August 2010.

On December 11, 2007, the keel of the first vessel of the class was laid down in Turku. In early 2008, Royal Caribbean ended months of speculation by announcing that their two Oasis class ships would be based year-round at Port Everglades, Florida.

On April 15, 2008, Royal Caribbean held a press conference in New York City to release the first official information and renderings of "Central Park", a 5-deck high area in the middle of the ship, open to the sky and filled with lush tropical gardens, upscale restaurants and shops. The area, one of seven "neighborhoods" onboard the ship, also features the Rising Tide Bar, which will move up and down through 3 decks. There will be 334 staterooms overlooking the Park, 254 with balconies - four of which are wheelchair accessible. Two arched-glass domes in Central Park called the Crystal Canopies will provide sunlight into the ship's inner public spaces.

one of the biggest !

Container Ship - Emma Maersk

Emma Mærsk is a container ship owned by the A. P. Moller-Maersk Group. When she was launched, Emma Mærsk was the largest container ship ever built, and as of 2008 the longest ship in use. Officially, Emma Mærsk is able to carry around 11,000twenty-foot equivalent units(TEU) according to the Maersk company's method of calculating capacity, which is about 1,400 more containers than any other ship is capable of carrying.

General Characteristics

Tonnage:	170,974 GT (55,396 NT)
Length:	397 metres (1,300ft)
Beam:	56 metres (180ft)
Draft:	15.5 metres (51ft)
Capacity:	156,907 DWT, 11,000TEU

By normal calculations, Emma Mærsk's cargo capacity is significantly greater than the listed capacity — between 13,500twenty-foot equivalent units(TEU) and 15,200TEU. The difference between the official and estimated numbers is because Maersk calculates the capacity of a container ship by weight (in this case, 14 tons/container) that can be carried on a vessel. For the Emma Mærsk, this is 11,000 containers. Other companies calculate the capacity of a container ship according to the maximum number of containers that can be put on the ship, independent of the weight of the containers. This number is always greater than the number calculated by the Maersk method.

The ship was built at the Odense Steel Shipyard in Denmark. In June 2006, during construction, welding work caused a fire within her superstructure. It spread rapidly through the accommodation section and bridge.

Emma Mærsk was named in a ceremony on August 12, 2006. The ship is named after Emma Mærsk, Mærsk Mc-Kinney Møller's late wife. The ship set sail on her maiden voyage on 8 September 2006 at 02:00 hours from Aarhus, calling at Gothenburg, Bremerhaven, Rotterdam, Algeciras, the Suez Canal, and arrived in Singapore on 1 October 2006 at 20:05 hours.

Emma Mærsk departed Singapore the next day, headed for Yantian in Shenzhen. She sailed on to Kobe, Nagoya, arrived at Yokohama on 10 October 2006, and returned via Shenzhen, Hong Kong, Tanjung Pelepas, the Suez Canal, Felixstowe, Rotterdam, Bremerhaven, Gothenburg and finally to Aarhus, with arrival at that port 11 November 2006 at 16:00 hours.

She appeared in headlines prior to Christmas 2006, when she was dubbed SS Santa because she was bound for the United Kingdom from China loaded with Christmas goods. The return journey after Christmas 2006 saw her return to southern China, loaded with UK waste destined for recycling in China.

Her appearance in the news prompted China's State Environmental Protection Administration to promise to "closely watch the progress of investigation into the dumping of garbage in south China by Britain". It added that no official approval had been given to any company in the area to import waste.

Emma Maersk's regular round trip involves Ningbo, Xiamen, Hong Kong (westbound), Yantian (westbound), Tanjung Pelepas (westbound), Algeciras (westbound), Rotterdam, Bremerhaven, Algeciras (eastbound), Tanjung Pelepas (eastbound), Yantian (eastbound), Hong Kong (eastbound) and Ningbo.
