A Bridge that Rotates… An Engineering Marvel !!!
So what happens when you combine Engineering and limitations? Engineers are usually accustomed to thinking out of the box but every once in a while they tend to come up with something quite magnificent and legendary, such as; The Gateshead Millennium Bridge. The Bridge has been constructed upon River Tyne in England and is different from other bridges in a very unique way. We have Gateshead’s Quays arts quarter at the south bank while Quayside of Newcastle on the north bank.
Bridge itself is essentially an assembly of two peculiar curves. One of these curves serves as the deck while the other supports it via cables. The idea was to entertain pedestrians and cyclists while also entertaining the ships that make use of river. So whenever a ship needs to pass through, the whole bridge rotates as a single assembly where both curves counter-balance each other as one rises up and the other drops down to give way to ships. These curves, parabolic in nature, extend the crossing distance of 105 meters to almost 120 meters providing an adequate length for the clearance above water.
The Bridge is also known as ‘Blinking/Winking Eye’ because of the way it looks when it is in motion. Stylish and elegant are the words used to describe the motion of this bridge and watching it work is always a great view to look at. The operation of the bridge requires the use of six 45 cm diameter Hydraulic rams, equally distributed and each requiring the power of a 55kW electric motor to function. The bridge rotates a total of 40 degrees and it takes around 4.5 minutes to complete the rotation,though wind speed has a say in this time too.

bridge has won quite a number of awards over its design including the architects Wilkinson Eyre, the 2002 Royal Institute of British Architects (RIBA) Stirling Prize, the 2003 Gifford IStructE Supreme Award, and in 2005, the Outstanding Structure Award from International Association for Bridge and Structural Engineering (IABSE).

Message For the Day…” Have Tolerance and Patience with Mutual Helping Attitude “..
|
Spiritual Practice (Sadhana) must be done in a disciplined and systematic manner, in an atmosphere filled with virtues. Just as fans in a large hall cool the atmosphere and provide soothing breeze to the people gathered there, so too, the fans of Truth, Right Conduct, Peace and Love (Sathya, Dharma, Shanthi,and Prema) are necessary to reduce the sweltering heat of ignorance, falsehood, injustice and indiscipline (Ajnaana, Asathya, Anyaaya and Akrama). In a world where noble conduct is being insulted and denied at every turn, peace and tolerance are the only means through which you can save yourself. This is the most important aspect that I ask you to cultivate. In every act, have tolerance and patience with a mutual helping attitude. In the family, cultivate patience and mutual respect; in the community, have righteousness and justice.

Is it True NASA Used Space pens and Russia Used Pencils ???!!!
NASA Spent $12 Million For a Space Pen While the Russians Just Use Pencils-Fiction!
Summary of the eRumor
The message says that the U.S. National Aeronautics and Space Administration spent ten years and $12 million developing a pen that writes in zero gravity for use by astronauts. The pen will write upside down, underwater, on almost any surface and is functional at extremely hot and cold temperatures. The Russians, however, filled the need for a space writing instrument by simply using pencils.
The Truth
For some people, it’s sport to point out government waste and bureaucratic stupidity, but this story about the space pen won’t provide ammunition for it. The government did not fund the development of the pen, it did not cost $12 million to perfect, and neither the Americans nor the Russians consider it desirable to use pencils in space. In fact, both Americans and Russians use the space pen for their flights.
The famous space pen, which is still a popular product today, was developed by Paul Fisher the founder of the Fisher pen company. An engineer who improved ball point technology, he created his “bullet pen” in the 1940’s, which became one of the best-selling pens of the Twentieth Century. Later, he perfected a pen that was sealed with pressure inside of the cartridge that made the ink to flow regardless of gravity. It also worked in high and low temperature extremes, underwater, and wrote on many kinds of surfaces. According to the Fisher Pen company, after extensive testing, NASA chose the pen in 1967 for use by Apollo astronauts and it’s been a part of space travel ever since. The company says it took Fisher about 2 years and $2 million to develop the space pen. Prior to 1967, there were no pens that worked in space so there were pencils used, but there were concerns about pencil dust floating around the space capsules as well as fears that if the tip of a pencil broke off and drifted into the electronics, there would be problems.
A real example of the eRumor as it has appeared on the Internet:
When NASA first started sending up astronauts, they discovered that ball-point pens would not work in zero gravity. To combat this problem, NASA scientists spent a decade and $12 million developing a pen that writes in zero gravity, upside down, underwater, on almost any surface including glass and at temperatures ranging from below freezing to over 300C.
When confronted with the same problem, the Russians used a pencil.

படித்ததில் பிடித்தது …. “பெருமாளை துணைக்கு அழைப்பது ஏன் ?”
புரிந்தது …..தெளிந்தது !!!
ஒரு துறவி தன் சீடனுடன் குடிலில் அமர்ந்திருந்தார்.
ஒரு குடும்பஸ்தர் வந்தார்.
“”சுவாமி! எனக்கு ஆயிரம் கடன்கள். பெண்ணுக்கு கல்யாணம் செய்ய வழியில்லை. உடல்நிலையும் சரியில்லை. இந்த பிரச்னை தீர யோசனை கூறுங்கள்…” என்று கேட்டார்.
“”அப்பனே! இதுவிதிப்பயன். மாற்றலாகாது. பெருமாள் நாமத்தை மனதார உச்சரி; கஷ்டங்களைக் குறைக்கலாம்,” என்றார் துறவி.
வந்தவர் விரக்தியாய் கேட்டார்.
“”உங்கள் கூற்றுப்படி, விதிப்படி தான் எல்லாம் நடக்குமென்றால், பெருமாளை துணைக்கு அழைப்பானேன்! அவன் நாமத்தை
சொல்லுவானேன்!”.
குரு சிரித்தார்.
“”மகனே! பெருமாள் கிருஷ்ணாவதாரம், ராமாவதாரம் எடுத்தார். மனிதரூபத்தில் இருந்தார். அவர் நினைத்தால் எல்லாவற்றையும் மாற்றியிருக்க முடியும். ஆனால், அதர்மத்தை நடக்க விட்டதும், பெரும் துன்பப் போராட்டத்திற்குப் பின், தர்மத்தை வெல்லச் செய்ததும். விதியின் வலிமையை உணர்த்துவதற்காகத் தான்! காய்ச்சல் வந்தால், மருந்து சாப்பிட்டு அதைக் குறைப்பது போலத்தான் விதியின் பாதை. அந்தப் பாதையை மாற்ற முடியாது. ஆனால், அதன் கடுமையை குறைக்கவே கடவுளிடம் வேண்டுகிறோம், புரிகிறதா!” என்றார்.
வந்தவருக்கு நன்றாய் புரிந்தது, மனம் தெளிந்தது
ஒரு பணக்காரரும், பரம ஏழையும் திருப்பதி சென்றனர். வேங்கடவன் அருள்வேண்டி தரிசனம் செய்தனர்.
அது திருவிழா காலம். எனவே, வழக்கமான கூட்டத்தை விட இரண்டரை மடங்கு கூட்டம்.
தரிசனம் முடித்த அவர்கள், லட்டுக்காக வரிசையில் காத்து நின்றனர். பணக்காரருக்கு நான்கு லட்டுகள் கிடைத்தது. ஏழையால் ஒன்றே ஒன்று தான் வாங்க முடிந்தது.
அவனுக்கு மிகவும் வருத்தம். மலைப்பாதையில் திரும்பி வரும் போது, ஒரு துறவியைச் சந்தித்தான்.
“”சுவாமி! செல்வந்தர்களால் எல்லாமே வாங்க முடிகிறது. ஏழையாய் பிறந்த பாவத்தால் என்னால், ஒரு லட்டு கூட அதிகமாக வாங்க முடியவில்லை,”. அவன் பரிதாபமாக சொன்னது கேட்டு, குரு சிரித்தார். அமைதியாய் பேசினார், “”மகனே! அந்த பணக்காரனுக்கு நாலு லட்டு கிடைத்திருக்கலாம். ஆனால், அவரால் துளிக்கூட உண்ண இயலாது. அவர் சர்க்கரை வியாதிக்காரர். ஆனாலும், அவர் அவற்றை வாங்கியது ஏன் தெரியுமா! தன் உறவுகளுக்கும், நண்பர்களுக்கும் பகிர்ந்தளிக்க..! பக்தியின் நோக்கம் என்ன தெரியுமா?
பிறருக்கு பகிர்ந்தளித்தல் தான்! அவரவருக்கு கிடைப்பதில், எவ்வளவு முடியுமோ அவ்வளவை மற்றவர்களுக்கு பகிர்ந்தளிக்க வேண்டும். அது மட்டுமல்ல! இதிலே இன்னொரு தத்துவமும் புதைந்து கிடக்கிறது.
திருப்பதி லட்டு அமிர்தம் போல் சுவையானது. இதை யாருக்காவது சிறு துண்டு கொடுத்தால் கூட, இன்னொரு துண்டு கிடைக்காதா என ஏங்க வைக்கும். இறைவனின் கருணையும் அப்படித்தான்.
அவனது கருணை மழையில் சிறுதுளியாவது கிடைக்காதா என்றுதான், ஒவ்வொரு பக்தனும் ஏங்குகிறான்.
உனக்கு கிடைத்த இந்த ஒரு லட்டில் சிறு துண்டை, நீ எடுத்துக்கொள். மீதியை மற்றவர்களுக்கு பகிர்ந்து கொடு. ஏழுமலையான் உன் வீட்டிற்கே வந்து விடுவான்,” என்றார்.
ஏழையின் மனம் தெளிந்தது.

Message for the Day…”You are part and parcel of Universe Manifestation “…
Often you are aware that there is something behind and beyond all the fleeting fantasy; something that persists through all the successes and defeats, the tears and smiles, the mirth and moan – but you are unable to grasp it and realize that it is the same Entity that underlies the entire Universe. You are indeed one with the most distant star and the least little blade of grass – you shine as dew on the petal of the rose, you are part and parcel of all this manifestation! The scriptures teach you this truth through many a parable, and even directly through the experience of saints and mystics. Through meditation and practice of spiritual discipline, you can be aware of yourselves as all this. Hanuman may have the form of a monkey, but do not get carried away by the outer casement (Upadhi). The Lord was His very breath; every hair-end of Hanuman echoed with Lord Rama’s Name

SO THIS is what the plane spotters hang out for.
These unbelievable mile-high snaps have been released by aviation photographersAirTeamImages to celebrate its 10th birthday, and they provide a unique glimpse into life in the skies.
From hundreds of birds surrounding a Boeing 777 at Heathrow Airport, to a Boeing F/A-18 Super Hornet visibly breaking the sounds barrier above San Francisco, these remarkable mile-high moments are usually never witnessed by passengers.
Other highlights include the look on a pilot’s face as his small plane turns upside down, a jumbo jet swooping low over sunbathers, and a view of lightning from the cockpit of a Jetstar plane.

AirTeamImages was established in 2003 by the world renowned aviation photographer Derek Pedley.
“We are the largest supplier of aviation images in the world,” he said. “We have 200 photographers which I have hand-picked and we have a portfolio of images that tell the whole history of aviation right back to the 1900s.

Pedley’s love of planes began when he was a child.
“I have a real fascination with planes, which was probably kickstarted by me growing up next to Birmingham Airport,” he said.
“I would go with my friends and play football behind the fences which ran alongside the runways. When photography came along it helped to keep the interest going, and here I am today.”
