Large Hadron Collider (LHC)

 

The Large Hadron Collider (LHC) is the world's largest particle accelerator complex, intended to collide opposing beams of 7 TeV protons. Its main purpose is to explore the validity and limitations of the Standard Model, the current theoretical picture for particle physics. The LHC was built by the European Organization for Nuclear Research (CERN), and lies underneath the Franco-Swiss border near Geneva, Switzerland.

The LHC is the world's largest and the highest-energy particle accelerator. It is funded by and built in collaboration with over eight thousand physicists from over eighty-five countries as well as hundreds of universities and laboratories.

The LHC is now operational, and in the process of being prepared for first collisions. The first beam was circulated through the collider on the morning of September 10, 2008. The first high-energy collisions are planned to take place after the LHC is officially unveiled on 21 October 2008.

When activated, it is theorized that the collider will produce the elusive Higgs boson, the observation of which could confirm the predictions and missing links in the Standard Model of physics and could explain how other elementary particles acquire properties such as mass.

Although a few individuals have questioned the safety of the planned experiments in the media and through the courts, the consensus in the scientific community is that there is no basis for any conceivable threat from the LHC particle collisions.

Onam activities

The most important things about Onam are the onakkodi, the new clothes worn on this day and onam sadya, a feast which is quite elaborate. This is usually a feast served on banana leaves and serves rice along with at least an array of 4 dishes. Traditional pickles and papadam are also served. Dessert is usually 'payasam', a sweet dish made of milk, sugar and other traditional Indian savories.

During Onam, people create a multi-coloured floral decoration on the ground in the front of their home calledpookkalam. Young children especially girls are often entrusted with the task of gathering and laying out the flowers in elaborate patterns. Competitions are held on onam day to create this floral design. It is usually 1.5 m in Diameter usually in circular shape. A lamp is usually placed as part of the design. In the recent years, the floral designs have evoloved from the traditional circular shape to unique designs depicting different cultural and social aspects of Kerala life.

The Vallamkali (the snake boat race) is another event that is synonymous with Onam. Well-known races include theAranmula Boat Race and the Nehru Trophy Boat Race. About 100 oarsmen row huge and graceful snake boats and men and women come from far and near to watch the snake boats skim through the water.

During the Onam, Keralite Hindus install an image of Thrikkakara Appan (Vishnu in the form of Vamana) in their home just as Hindus install images or murtis of Lord Ganesh on the Ganesh Chaturi festival.

This festival is also important because of its popularity with all communities within Kerala. Although the festival of Onam originated with, and is connected to the Hindu religion, it is celebrated today with equal fervour by the Hindus, Muslims and Christians of Kerala.

Many lamps are lit in Hindu temples of Kerala during this celebration. A palmyra tree is erected in front of temples and surrounded with a wooden balustrade and covered with dry palmyra leaves. It is lit with a torch and burned to ashes to signify that Mahabali went to hell as a sacrifice

Story Behind Onam

A long long time ago, an Asura (demon) king called Mahabali ruled Kerala. He was a wise, benevolent and judicious ruler and beloved of his subjects. Soon his fame as an able king began to spread far and wide, but when he extended his rule to the heavens and the netherworld, the gods felt challenged and began to fear his growing powers. Presuming that he might become over-powerful, Aditi, the mother of Devas pleaded with Lord Vishnu to curtail Mahabali's powers.

Vishnu transformed himself into a dwarf called Vamana and approached Mahabali while he was performing a yajna and asked for alms. Pleased with the dwarf brahmin's wisdom, Mahabali granted him a wish. The Emperor's preceptor, Sukracharya warned him against making the gift, for he realized that the seeker was no ordinary person. But the Emperor's kingly ego was boosted to think that God had asked him for a favor. So he firmly declared that there is no greater sin than going back on one's promise. He kept his word.

The Vamana asked for a simple gift — three paces of land — and the king agreed to it. Vishnu in the guise of Vamana then increased his stature and with the first step covered the sky, blotting out the stars, and with the second, straddled the netherworld. Realising that Vamana's third step will destroy the earth, Mahabali offered his head as the last step.

Vishnu's fatal third step pushed him to the netherworld, but before banishing him to the underworld Vishnu granted him a boon. Since he was attached to his kingdom and his people, he was allowed to return once a year from exile. Onam is the celebration that marks the homecoming of King Mahabali. It is the day when a grateful Kerala pays a glorious tribute to the memory of this benign king who gave his all for his subjects.
