Origin, History and Traditions of Halloween..





Halloween is a traditional celebration held on October 31st. Today, Halloween is an excuse for Halloween theme costume parties, and entertainment with horror films, haunted houses and other activities around the popular themes of ghosts, witches, Dracula, werewolves and the supernatural. Children love to dress up in halloween costumes and go from door-to-door in their neighborhood following the old tradition of trick-or-treating, collecting sweets and gifts, sometimes money.


Halloween began as an ancient Celtic festival in Great Britain and Ireland, and has survived most strongly among Irish, Scottish and Welsh communities. Immigrants from these communities carried the tradition to North America where it has gained in popularity. In turn, as part of American pop culture, Halloween has spread in popularity to most corners of the English speaking western world, and increasingly into Western Europe in recent times.


Originally Halloween was a pagan festival, around the idea of linking the living with the dead, when contact became possible between the spirits and the physical world, and magical things were more likely to happen. Like most pagan festivals, long ago it was absorbed into the festivals of the expanding Christian church, and became associated with All Hallows Day, or All Saints Day, which eventually fell on November 1 under the Gregorian calendar. A vigil for the festival was held on All Hallows Evening on October 31. In the vernacular of the times, All Hallows Evening became Hallowe'en and later the Halloween we know today.


The celebration of Halloween survived most strongly in Ireland. It was an end of summer festival, and was often celebrated in each community with a bonfire to ward off the evil spirits. Children would go from door to door in disguise as creatures from the underworld to collect treats, mainly fruit, nuts and the like for the festivities. These were used for playing traditional games like eating an apple on a string or bobbing for apples and other gifts in a basin of water, without using your hands. Salt might be sprinkled on the visiting children to ward off evil spirits. Carving turnips as ghoulish faces to hold candles became a popular part of the festival, which has been adapted to carving pumpkins in America.


Halloween is usually celebrated by both adults and kids. Some families celebrate by having costume parties and playing special games like bobbing for apples and telling ghost stories. Sometimes children go "trick or treating" - knocking on doors in their trusted neighborhoods collecting candy. Other times they may attend a community party instead. Parents should use common sense when supervising their child's Halloween activities.


In earlier years, Halloween was a time for playing harmless pranks. However, in more recent times, Halloween pranks have sometimes gotten out of hand - causing damage and injury to others.

India’s lunar mission finds evidence of water on the Moon

India’s lunar mission finds evidence of water on the Moon

Dreams of establishing a manned Moon base could become reality within two decades after India’s first lunar mission found evidence of large quantities of water on its surface.

Data from Chandrayaan-1 also suggests that water is still being formed on the Moon. Scientists said the breakthrough — to be announced by Nasa at a press conference — would change the face of lunar exploration.

The discovery is a significant boost for India in its space race against China. Dr Mylswamy Annadurai, the mission’s project director at the Indian Space Research Organisation in Bangalore, said: “It’s very satisfying.”

"The observations presented here show a combination of hydroxyl, OH (oxygen hydrogen molecules), and H2O (water) that resides in the upper few millimeters of the lunar surface," said Jim Green, director of NASA's Planetary Science Division. "The average amount of water reported, if we were to extract it, is about a quart of water per ton (of surface soil)."
To put it another way, he said, about 16 ounces of water might be present for every 1,000 pounds of surface soil near the moon's poles. For soil near the equator, only about two tablespoons of water is believed to be present in every 1,000 pounds.

Early results from Nasa’s Lunar Reconnaissance Orbiter (LRO) recorded temperatures as low as -238C (minus 396.4F) in polar craters on the Moon, according to the journal Nature. That makes them the coldest recorded spots in the solar system, even colder than the surface of Pluto, and could mean that ice has been trapped for billions of years, the journal said. The LRO has also detected an abundance of hydrogen, thought to be a key indicator of ice, at the poles.

India's Independence Day



"At the stroke of the midnight hour, when the world sleeps, India will awake to life and freedom. A moment comes, which comes but rarely in history, when we step out from the old to the new…India discovers herself again."
- Jawaharlal Nehru
(on Indian Independence Day, 1947)


After more than two hundred years of British rule, India finally won backs its freedom on 15th August, 1947. All the patriotic hearts rejoiced at seeing India becoming a sovereign nation and the triumph of hundreds and thousands of martyred souls. It was a birth of a new nation and a new beginning. The only fact that marred the happiness of the fruits by the blood of martyrs was the fact that the country was divided into India and Pakistan and the violent communal riots took away a number of lives. It was on the eve of 15th of August, 1947 that India tricolor flag was unfurled by Jawahar Lal Nehru, the first Prime Minister of India, on the ramparts the Red Fort of Delhi.

The day is celebrated to commemorate the birth of the world's biggest democracy as a national holiday. Schools and people hoist the national flag through out the country and put them up on the rooftops and the buildings. People only go to offices to attend the flag hoisting ceremony. The Prime Minister addresses the Nation after the flag has been unfurled recounting the country's achievements of the year, discussing current major issues and future plans for the progress of the country. Recently, kite-flying has become a tradition on this day and people can be seen flying numerous kites of all colors, sizes and shapes symbolizing the freedom.

Rakhi: The Thread of Love



In India, festivals are the celebration of togetherness the celebrations of being one of the family. Raksha Bandhan is one such festival that is all about affection, fraternity and sublime sentiments. It is also known as Raksha Bandhan which means a 'bond of protection. This is an occasion to flourish love, care, affection and sacred feeling of brotherhood.

Not a single festival in India is complete without the typical Indian festivities, the gatherings, celebrations, exchange of sweets and gifts, lots of noise, singing and dancing. Raksha Bandhan is a regional celebration to celebrate the sacred relation between brothers and sisters. Primarily, this festival belongs to north and western region of India but soon the world has started celebrating this festival with the same verse and spirit. Rakhi has become an integral part of those customs.

An insight of Rakhi Rituals
On the day of Rakhi, sisters prepares the pooja thali with diya, roli, chawal, rakhi thread and sweets. The ritual begins with a prayer in front of God, then the sister ties Rakhi to her brother and wishes for his happiness and well-being. In turn, the brother acknowledge the love with a promise to stand by his sister through all the good and bad times.

Sisters tie Rakhi on the wrist of their brothers amid chanting of mantras, put roli and rice on his forehead and pray for his well-being. She bestows him with gifts and blessings. In turn, brothers also wish her a good life and pledges to take care of her. He gives her a return gift. The gift symbolizes the physical acceptance of her love, reminder of their togetherness and his pledge. The legends and the reference in history repeated, the significance of the festival is emphasized.

Unconditional Bond of Love
Raksha bandhan has been celebrated in the same way with the same traditions for many years. Only the means have changed with the changing lifestyle to make the celebration more elaborate and lively. This day has an inherent power that pulls the siblings together. The increasing distances evoke the desire to be together even more. All brothers and sisters try to reach out to each other on this auspicious day. The joyous meeting, the rare family get-together, that erstwhile feeling of brotherhood and sisterhood calls for a massive celebration.

For everyone, it is an opportunity to reunion and celebrate. People also share tasty dishes, wonderful sweets and exchange gifts. It is a time to share their past experiences also. For those who are not able to meet each other, rakhi cards and e-rakhis and rakhis through mails perform the part of communicating the rakhi messages. Hand made rakhis and self-made rakhi cards are just representation of the personal feelings of the siblings.

Raksha Bandhan in History..



Raksha Bandhan
The traditional Hindu festival 'Raksha Bandhan' (knot of protection) was came into origin about 6000 years back when Aryans created first civilization - The Indus Valley Civilization. With many languages and cultures, the traditional method to Rakhi festival celebration differs from place to place across India. Following are some historical evidences of Raksha Bandhan celebration from the Indian history.

Rani Karnawati and Emperor Humayun
The story of Rani Karnavati and Emperor Humayun is the most significant evidence in the history. During the medieval era, Rajputs were fighting Muslim invasions. Rakhi at that time meant a spiritual binding and protection of sisters was foremost. When Rani Karnawati the widowed queen of the king of Chittor realised that she could in no way defend the invasion of the Sultan of Gujarat, Bahadur Shah, she sent a rakhi to Emperor Humayun. The Emperor touched by the gesture started off with his troops without wasting any time.

Alexander The Great and King Puru
The oldest reference to the festival of rakhi goes back to 300 B.C. at the time when Alexander invaded India. It is said that the great conqueror, King Alexander of Macedonia was shaken by the fury of the Indian king Puru in his first attempt. Upset by this, Alexander's wife, who had heard of the Rakhi festival, approached King Puru. King Puru accepted her as his sister and when the opportunity came during the war, he refrained from Alexander.

Lord Krishna and Draupathi
In order to protect the good people, Lord Krishna killed the evil King Shishupal. Krishna was hurt during the war and left with bleeding finger. Seeing this, Draupathi had torn a strip of cloth from her sari and tied around his wrist to stop the bleeding. Lord Krishna, realizing her affections and concern about him, declared himself bounded by her sisterly love. He promised her to repay this debt whenever she need in future. Many years later, when the pandavas lost Draupathi in the game of dice and Kauravas were removing her saari, Krishna helped her divinely elongating the saari so that they could not remove it.

King Bali and Goddess Lakshmi
The demon king Mahabali was a great devotee of lord Vishnu. Because of his immense devotion, Vishnu has taken the task of protecting bali's Kingdom leaving his normal place in Vikundam. Goddess lakshmi - the wife of lord Vishnu - has became sad because of this as she wanted lord Vishnu along with her. So she went to Bali and discussed as a Brahmin woman and taken refuge in his palace. On Shravana purnima, she tied Rakhi on King Bali's wrist. Goddess Lakshmi revealed who she is and why she is there. The king was touched by Her and Lord Vishnu's good will and affection towards him and his family, Bali requested Lord Vishnu to accompany her to vaikuntam. Due to this festival is also called Baleva as Bali Raja's devotion to the Lord vishnu. It is said that since that day it has become a tradition to invite sisters on sravan pournima to tie sacred thread of Rakhi or Raksha bandan.

Decision-Making Attack Drones..


Another terminator style weapon is soon coming but no Shawn Conner to save us from its wrath

Leave it to the military to dream big. In its recently released “Unmanned Aircraft Systems Flight Plan 2009-2047″ report, the US Air Force details a drone that could fly over a target and then make the decision whether or not to launch an attack, all without human intervention. The Air Force says that increasingly, humans will monitor situations, rather than be deciders or participants, and that “advances in AI will enable systems to make combat decisions and act within legal and policy constraints without necessarily requiring human input.” Programming of the drone will be based on “human intent,” with real actual humans monitoring the execution, while retaining the authority and ability to override the system. It’s all still extremely vague, with literally no details on exactly how this drone will come into existence, but we do know this: the Air Force plans to have these dudes operational by 2047. We’re just holding out to see what those “classified” pages are all about.

Another Biggest Tragedy In Human History-Tsunami will be back 22nd July 2009

I just wanted 2 let you all know “please stay away from the beaches all around in the month of July”
There is a prediction that there will be another tsunami hitting on 22nd July 2009. It is also when there will be a sun eclipse.
It is predicted that this tsunami will be a really bad one.
Countries like Malaysia (Sabah and Sarawak particularly), Singapore, Indonesia, Maldives, Australia, Mauritius, Si Lanka, India, Philippines are going to be badly hit.
Warning: STAY away from beaches in July.


I got this message via an email .




The first Tsunami that happen last time was shock the whole world and i believed, someone out there still leave a scare and hard to forget, the sadnest is some victims don't even got time to say out their last word...

Here is an unpublish and hidden infomation that i received :

There is a prediction that there will be another tsunami hitting on 2009 July 22nd, It is also when there will be sun eclipse. Predicted that it is going to be really bad and countries like Malaysia (Sabah & Sarawak), Singapore, Maldives, Australia, Mauritius, Sri Lanka, India, Indonesia, Philippines are going to be badly hit.

Look at the file picture below, you will find out. Please be more cautious as the warnings has been given.

However, this infomation had not yet been prove and i don't know where this infomation came from,( I received from my friend ), but is BETTER BE SAFE THAN SORRY.

So stay away from beach from today till after July 2009, I also don’t know the credibility of the content, but just beware.

Good luck, let us pray together hopefully the tragedy never happen or if so happen, it wouldn't affect human being so badly like last tim.

Solar for Dark Climates

Solar technology that generates both heat and electricity could make solar energy practical in places that aren't sunny.

Cool Energy, a startup based in Boulder, CO, is developing a system that produces heat and electricity from the sun. It could help make solar energy competitive with conventional sources of energy in relatively dark and cold climates, such as the northern half of the United States and countries such as Canada and Germany.

Solar generator: A prototype of a Stirling engine that's powered by a solar water heater.
Credit: Cool Energy

The company's system combines a conventional solar water heater with a new Stirling-engine-based generator that it is developing. In cool months, the solar heater provides hot water and space heating. In warmer months, excess heat is used to drive the Stirling engine and generate electricity.

Samuel Weaver, the company's president and CEO, says that the system is more economical than solar water heaters alone because it makes use of heat that would otherwise be wasted during summer months. The system will also pay for itself about twice as quickly as conventional solar photovoltaics will, he says. That's in part because it can efficiently offset heating bills in the winter--something that photovoltaics can't do--and in part because the evacuated tubes used to collect heat from the sun make better use of diffuse light than conventional solar panels do.

The system is designed to provide almost all of a house's heating needs. But the generator, which will produce only 1.5 kilowatts of power, won't be enough to power a house on its own. The system is designed to work with power from the grid, although the power is enough to run a refrigerator and a few lights in the event of a power failure.

The company's key innovation is the Stirling engine, which is designed to work at temperatures much lower than ordinary Stirling engines. In these engines, a piston is driven by heating up one side of the engine while keeping the opposite side cool. Ordinarily, the engines require temperatures of above 500 °C, but Cool Energy's engine is designed to run at the 200 degrees that solar water heaters provide.

The success of the technology, however, hinges on achieving the efficiency targets, says Dean Kamen, the inventor of the Segway, who is developing high-temperature Stirling engines for other applications, including transportation. "We need data," he says. The company's second prototype was only 10 percent efficient at converting heat into electricity. Its engineers hope to reach 20 percent with a new prototype.

A Stirling engine's efficiency is limited by the difference in temperature between the cool and hot side. Typically, reaching the necessary high temperatures using sunlight requires mirrors and lenses for concentrating the light and tracking systems for keeping the concentrators pointed at the sun. The concentrators require direct sunlight, so they don't work on overcast days, and they're too bulky to be mounted on the roof of a house.

To make a practical Stirling engine that runs at low temperatures and doesn't require concentrators, the engineers at Cool Energy addressed a problem with conventional engines that leads to wasted energy: heat leaks from the hot side of the system to the cool side, lowering the temperature difference between them. This happens because the materials required for high temperatures and pressures--typically metals--conduct heat. Working at lower temperatures, the engineers concluded, allows them to use materials such as plastics and certain ceramics that don't conduct heat, reducing these losses. These materials also help lower costs: they're cheaper than some of the metals typically used, and they don't require lubrication, improving the reliability of the engines and reducing maintenance costs.

Cool Energy's engineers are currently assembling the company's third prototype, which they say will allow them to reach their efficiency targets by the end of this summer, after which they plan to test pilot systems outside the lab. Within two years, they plan to manufacture enough systems to drive costs down and achieve their payback targets.
