YOU NEED: • Two paper clips • A magnet It is easy to hang a paper clip on the bottom of a magnet, as in the illustration. With a little more care you can suspend a second clip under the first. Once the two paper clips are connected, carefully lift away from the magnet the top clip of the chain. Once its is away from the magnet, will the second clip drop free? Interestingly, it will not! More powerful magnets will support a chain of three or more paper clips.   HOW DOES IT WORK?  In most objects the atoms have a tiny amount of magnetic force, but because their poles are not aligned with each other, these forces cancel each other out. In a magnet many more atoms are aligned, so they work together to create a greater force overall. A magnet also has the more...

YOU NEED: • A banana • A spring weight measure   The fact that weight is a force can be proved by weighing an object such as a banana, with a spring balance. Weigh it in air and re-weigh it submerged in water. You will find the banana weighs less in water. HOW DOES IT WORK? Since water exerts an up-ward thrust it reduces the pull of gravity on the banana. Therefore weight of water displaced by the banana equals the amount of up thrust exerted by the water which is why it weighs less.

YOU NEED: • Apiece of cardboard • Two pins • Some thread • A wooden board   On an oddly cut piece of cardboard punch three holes in three corners. Mount the shape on a board with a pin weight to a piece of thread. Hang the weight from the pin and draw a line along the thread. Repeat the procedure with the other holes. The point of intersection of the three lines is the centre of gravity.

YOU  NEED :

• Two pencils & Two Glasses
• Some wire
• Two strip
• 9 volt battery

  Sharpen two pencils at both ends with a long lead at one end of each pencil. Attach a wire to each pencil by wrapping its stripped ends around the long lead on one end. Connect the wires to a 9 volt battery. Now place the pencils in a bowl of water and add a tablespoon of vinegar to speed up the electrolysis. Take two glasses and place them, one over each pencil. At this stage electrolysis is breaking up the components of water and collects as hydrogen gas on the pencil connected to the negative terminal and as oxygen gas on the other terminal. Remember water contains twice as many hydrogen atoms as oxygen atoms.

"The Heights by the great men reached and kept, were not attained by sudden/light, But while their companions were slept, They were toiling upwards in the night."  It was a great moment of pride for India and the Indians, when the great Indian Economists, Prof. Amartya Sen was chosen for the Nobel Prize for Economics 1998. Prof. Sen was conferred the most coveted international award for his elegant contribution to "Welfare Economics" which throws light on the understanding of the economic mechanism under the circumstances of famine and poverty. With the recognition for his contribution to welfare economics. Dr. Sen, 64. Master of Trinity College at Cambridge University, became the sixth Indian to get the Nobel Prize and the first Asian to merit it for Economics. He is also the first solo winner of the prize for Economics since 1995. Prof. SenwasbomonNov.3, 1933 in Shantinekatan (Bengal). When he was just more...

"Oh, we want a new breed of men before India can he cleansed of her disease. We want deeper sincerity of motive, a greater courage in speech and earnestness in action. We want men who love this country and are full of yearning to serve and succor their brothers and not to further aid in their degradation by insincerity and self- seeking. 0 how I hate shams and prejudices: how I hate all sectarian narrowness, alt provincial limitations of vision and purpose, all the arrogant sophistries of man-made divisions and differences: how tired I am to death of the reiterated resolutions that have become almost meaningless by lip repetition: uncorroborated by the hearths conviction and unsuslained by practical action—all this stirs me more deeply just now because of the coming national week. What a. week of inspiration it should be to all partaking in the various activities, if only all more...

"Vallabhbhai Patel was born in Gujrat. He studied law in England but returned (1915) to India and practiced in Ahmedabad. Influenced by the nationalist leader Mohan Das Karam Chand Gandhi, he joined the civil disobedience movement and successfully organised (1928) the landowners of Kardoli against British tax increases, lit 1931 he served as President of the Indian National Congress. The British imprisoned Patel a number of limes for his activities. As home minister, minister afflatus, and deputy prime minister (1947-1950) under Jawaliarlal Nehru, Patel adroitly achieved the peaceful integration of the princely Indian Slates into the Union.

A lot of blood was sacrificed from the heart of Bengal to make India free. Mothers lost their children and wive their husbands. But none had wept because the stake was too high the chances too great and the ultimate result too fabulous to dream. At his tender youth, when Khudi Ram Bose became a martyr everybody wept silently but were inspired by his courage and took up arms for a battle against all odds.  Khudi Ram Bose was bom on 3rd Dec 1889 in Habibpur of Medinipur to Laxmipriya Devi and Trilokyanath Bose.

WTO, an International organization, is the outcome of several years of deliberations beginning from the end of Second World War and formulation of GATT in 1947. The GATT (General Agreement on Tariff and Trade) was established to regulate and facilitate the trade among the member nations for the sole purpose of boosting the economic growth and overall development. The first seven round of negotiations under GATT were focused to encourage the international trade by I reductions in trade barriers and trade tariffs. But with gradual changes in the world economic scenario, the developed countries to enhance their share trade with developing countries felt the need of a permanent body to look after the international trade and other related aspects. The 8th round of multilateral Trade Negotiations, known as Uruguay Round took place in 1986. The Uruguay round contained the mandate to have negotiation in 15 areas, while part I contained more...
