Festival of Lights

The biggest and the grandest Festival of Lights is here. A time of the year to rejoice and get together with family. I do miss mine being in Singapore. Wishing you all a prosperous diwali.
A small blog about diwali.
A colorful festival that is celebrated by all Hindus worldwide is Deepavali, which is also known as the festival of lights. This festival usually falls around late October and November. One important practice that the Hindus follow during the festival is to light oil lamps in their homes on Deepavali morning. By lighting the oil lamps, the Hindus are thanking the gods for the happiness, knowledge, peace and wealth that they have received. The Hindus consider Deepavali as one of the most important festivals to celebrate.
The Legend - There is even an interesting legend behind this festival. The story goes that Narakasura, a demon, ruled the kingdom of Pradyoshapuram. Under his rule, the villagers suffered a lot of hardship as the demon tortured the people and kidnapped the women to be imprisoned in his palace. Seeing his wickedness, Lord Khrishna set out to destroy the demon and the day Narakasura died was celebrated as Deepavali, the triumph of good over evil!
Preparations - Preparation for Deepavali starts usually at least two to three weeks before the festival. It is known that the Hindus will be busy cleaning their houses to prepare for the festival. Some would even renovate their houses to prepare it for Deepavali. Usually the family will shop for new clothes and for accessories to decorate their homes. Prior to the festival, Indian shops will be selling festive items like Deepavali greeting cards, carpets, Punjabi suits and flowers. The Hindus will frequent these shops when they are shopping for Deepavali.
Celebrations - The Hindus usually awake early in the morning of deepavali around 3am and the first ritual will be having an oil bath, which is an important feature of Deepavali. Hindus will be dressed in their new clothes on Deepavali. Most of the ladies would be clad in silk saris or Punjabi suits of various bright shades. Hindus particularly dislike dressing in black on that day, as they consider black an inauspicious color for the festival. Hindus would also pay their respects to the elderly and most families would go to the temple after having breakfast. This is also an important practice for them. The reason why they would be going to the temples is to pray to get happiness and prosperity on Deepavali. The houses would be decorated with oil lamps and children will play with firecrackers to celebrate the festival. On the first day, they would not go visiting but would stay at home to welcome the guests who visit them.
Food - Visiting Hindus during Deepavali will be an interesting activity, as you will get to taste a wide variety of delicious food. In every home that you visit you are bound to be served with a tempting spread of sweets. Some of the popular sweets are halwa, burfi and laddu. Hindus love eating spicy food and for non-vegetarians they indulge in favorites like chicken tandoori, prawn sambal and fish head curry. In homes of Hindus who are vegetarians popular dishes like thosais, idlis and naans are prepared.

A nice book to read
I have chanced upon a book which my roommate was reading and i too started to read that book. Thought it is much voluminous and the topic of the book blocked my from setting hand on it, i discovered tat it was worth a read later. I havnt completed the book, but its first few topic kept me interested in it. This book requires a lot of patience and of course the ability to imagine the authors story for a rich feel of it. will post u my ideas on the various issues once i finish the book. Meanwhile try to go for it...
Its "INDIA AFTER GANDHI"..."RAMACHANDRA GUHA"

The Irony of the Indian Cabinet
That is the final point. It is good that Dr Manmohan Singh exercised his veto, but it is a shame that the world's largest democracy still has a chief executive who does not belong to the list of persons elected by the people.
P.S. With a note of thanks to rediff for the data

Tired of Charging mobiles and IPODs??
This is my true technical blog considering that i am a postgrad in electrical engineering. There is an interesting development going on in the electrical faternity for easing customer troubles. I had attended a IEEE (Institute of Electrical and Electronics Engineers) seminar of charging of mobile phones without the use of wires. It dealt with nano-transformers based charge pads. The charging could be done by just placing the mobile phone on a pad which would charge the phones. Upon further online scouting i found an interesting research going on in this field.
In a research presented at the American Chemical Society's 237th National Meeting in Salt Lake City, Utah on March 26,2009, scientists from Georgia describe technology that converts mechanical energy from body movements or even the flow of blood in the body into electric energy that can be used to power a broad range of electronic devices without using batteries.
"This research will have a major impact on defense technology, environmental monitoring, biomedical sciences and even personal electronics," says lead researcher Zhong Lin Wang, Regents' Professor, School of Material Science and Engineering at the Georgia Institute of Technology. The new "nanogenerator" could have countless applications, among them a way to run electronic devices used by the military when troops are far in the field.
The researchers describe harvesting energy from the environment by converting low-frequency vibrations, like simple body movements, the beating of the heart or movement of the wind, into electricity, using zinc oxide (ZnO) nanowires that conduct the electricity. The ZnO nanowires are piezoelectric — they generate an electric current when subjected to mechanical stress. The diameter and length of the wire are 1/5,000th and 1/25th the diameter of a human hair.
In generating energy from movement, Wang says his team concluded that it was most effective to develop a method that worked at low frequencies and was based on flexible materials. The ZnO nanowires met these requirements. At the same time, he says a real advantage of this technology is that the nanowires can be grown easily on a wide variety of surfaces, and the nanogenerators will operate in the air or in liquids once properly packaged. Among the surfaces on which the nanowires can be grown are metals, ceramics, polymers, clothing and even tents.
"Quite simply, this technology can be used to generate energy under any circumstances as long as there is movement," according to Wang.
To date, he says that there have been limited methods created to produce nanopower despite the growing need by the military and defense agencies for nanoscale sensing devices used to detect bioterror agents. The nanogenerator would be particularly critical to troops in the field, where they are far from energy sources and need to use sensors or communication devices. In addition, having a sensor which doesn't need batteries could be extremely useful to the military and police sampling air for potential bioterrorism attacks in the United States, Wang says.
While biosensors have been miniaturized and can be implanted under the skin, he points out that these devices still require batteries, and the new nanogenerator would offer much more flexibility.
A major advantage of this new technology is that many nanogenerators can produce electricity continuously and simultaneously. On the other hand, the greatest challenge in developing these nanogenerators is to improve the output voltage and power, he says.
Last year Wang's group presented a study on nanogenerators driven by ultrasound. Today's research represents a much broader application of nanogenerators as driven by low-frequency body movement.
The study was funded by the Defense Advanced Research Projects Agency, the Department of Energy, the National Institutes of Health and the National Science Foundation.
