Kemangudi, a place called trackers hill station, its some what 280-290 km from bangalore a overnight journey. Really awsome place to hangout with friends.

Its not that famous like ooty and kodai, as its under developed hills station, The weather is so pleasant you will forget everything, you will just see fog and dark out by 4 pm in the evening.

But make sure to carry your own food as there is only one hotel whihch is not good, also only one place to accomodate so book in advance.

a long downward tracking towards the fall makes it more happening, just feel the very cold water in d fall.

But be cautious about the litches, its everywhere in during tracking, its advisable to carry salt or detol with you.

also while going its recomended to wear tight shoes and full jeans to avoid litches, thats the only scarry part of tracking else everything is awsome.

after coming back from tracking you will be so tired, a cup of tea makes you feel the taste of wiskey :)

You wont get anything except tea and normal food there so advisable to carry your stuffs well in advace.

The air is so fresh you will love to breath like anything.

I will recomend the travellers to visit the place once. I have seen many places till the date, but I like it the most. a hidden place still good and in full nature because of less human activities.

Kemangudi a track for trackers.

Man has always been curious to know about things and places. It is this curiosity which has held led him to discover and explore various places on this earth. One good thing about adventure or exploration is that there is no age bar for it. Even a child or a very old man can go on an adventurous journey. Let us know about the adventures of Marco Polo, who was an Italian boy.

Marco polo was a boy of seventeen, ant not very strong, when he set out on his travels. He went to China with his father and uncle. It was the year 1271, and the place where he lived was Venice in Italy. Marco polo’s father and uncle had already been once to china and had come back to visit their home. This time they decided to take Marco polo with them. They had to go over mountains, cross terrible deserts, through hot burning lands and laces where it was freezing cold. At times, Marco polo was ill on account of the hard and hazardous journey, but he got better and kept bravely on.

It took Marco polo, his father and his uncle there years to reach china. Kublai khan, the great king o china, welcomed them at is court. Marco polo grew up at the Chinese court and became a great favorite of the king. He learnt to speak several languages and was so clever that the king sent him to India and other lands as his ambassador. Each time when he came back, he told the king all. About the places he had visited how the people there lived, what their trades were, what the big cities were like and what messages were given to him for the king. Kublai khan was so happy with Marco polo that he heaped riches on him, his father and is uncle.

The Polos were happy at the Chinese court. Still they wanted to return to Venice. The king was unwilling to let them go, but he consented in the end and they left china for their native land. It was 1295, when the three travelers arrived in Venice. They were dressed in threadbare clothes and they spoke a strange language. Nobody recognized the, for they had been away for twenty-four years and even their family and given them up for dead. But they insisted that although they had forgotten to speak the Italian language, they were Italians and Venice was their home. Marco, who was a seventeen-year old boy when he had left, was a middle aged man now.

Marco polo told the people of Venice wonderful things about china. The Chinese, he explained, did not write their books by hand- instead, they printed many books t a time. They used clocks which were powered by water. They made colorful fireworks from a strange thing called gunpowder.

At that time in Italy, o one had heard about gunpowder or printing or clocks. People thought the three men were mad. Suddenly Marco polo cut open the patches in his old clothes and out tumbled several jewels like diamonds, rubies and pearls. Then the people believed that the strangers were really the Polos, back from a marvelous journey to far –off lands and that all Marco polo’s wonderful tales be true.

In 1298, Marco polo wrote down his experience in a book called description of the word. This book influenced many European explores including Christopher Columbus.

The first of the Hindu mathematicians was ARYABHATTA who lived in or near the present city Patna on the Ganges, in Bihar state of India. He was born in Kusumpuram and wrote his famous work The Aryabhattiya in 499A.D at the age of 23. In addition to the other contributions of Aryabhatta this voluminous work is enough to place him among the first ranking astronomers and the mathematicians of the world.

From the writings of Bhaskara, it appears that Aryabhatta took up the profession of a teacher. He earned fame as a great scholar and a teacher of astronomy.

Aryabhatta's contribution to the field of mathematics is extremely significant. He gave a systematic approach to Arithmetic, Algebra and Trigonometry. He was the 1st mathematician who gave the value of ∏ (pi) correct upto four decimal places.

Aryabhatta gave a method to find the cube root of numbers and dealt with arithmetic,geometric and indeterminate equations in algebra. He dealt with square,cube,triangle,trapezium,circle and sphere in geometry.

Aryabhatta occupies the 1st position among the astronomers of not only India but the whole world by telling that Earth is moving around the Sun. This knowledge about the Earth given by Aryabhatta was much beyond the imagination of scholars even after 1000 years of Aryabhatta.

However, Parthdak Swami(860A.D) and Copernicus(1600A.D) supported Aryabhatta and his Principle of rotation of the Earth around the Sun.
