The value of 'PI" was first calculated by the indian mathmatician Budhayana. and he explained the concept of what is know as the Pythagorean theorem. He discovered this in the 6th centuary, which was long before the European mathmaticians.

The university of Nagaland built in the 4th centuary was one of the greatest achievements of the ancient india in the field of education. Ayurveda is the earliest school of medicine know to mankind. the father of medicine, charaka, consolidated ayurveda 2500 year ago.
Home From Many Lands:- The kind of home we live in depends on the kind of climate we have and the building materials we can use. The Bedouin tent is easy to carry about and good at keeping out the sun in the desert. The Swiss chalet has a sloping roof so that snow slides oft it. Ahouse on stilts is useful in a land where there are many floods. In cities there is very little land for building. Large numbers of people often live crowded together. Some people live on top of one another in tall apartment blocks. Example. Eskimose once used to build homes called igloos from blocks of ice, In the Middle East the wandering Bedouin tribes live in tents, A suit in the in the Philipines, Swiss chalet, Woven grass and branches make cool, movable homes in partys of Africa, All over the world people live in boats. This one is in India. An adult giraffe's kick is so powerful that it can kill a lion. When angered, the tasmania devil, a mansupial with mainly black fur, tums pinkish red. squirrels can climb tress faster than they can run on the ground. the hipoptamus has a 4cm thick skin so solid that most bullet can't penetrate it.
A grasshopper's blood is green in colour.
In India have 17 major languages and 844 dialects spoke in india. India was one of the richest countries on earth until british invasion in the early 17th centuary. India invented the number system and aryabhat was the scientist who invented the digit zero("0"). Chess also invented by india and it is the 6th largest country in the world, the largest democracy and one of the oldest cicilization. India has the most number of mosques, it has 3000,000 mosques which much more than the muslim world. it the one of the largest exporter of computer software products. before 1985, india was the only place in the world where diamonds could be found. The biggest and the largest employer in the world is indian railways emplying over a million people. India has the most number of post office in the world.

Although modern images and descriptions of india often show poverty, india was one of the richest countreis till the time of British in the earlyy 17th century. Christopher Columbus was attracted by india wealth and was looking for route to india when he discovered America by mistake. The art of navigation and navigating was born in the river sind 6000 over years ago. The very word 'Navigation' is derived from the Sanskrit word NAVGATIH. The word navy is also derived from the sanskrit word 'Nou'. Bhaskaracharya rightly calculated the time taken by the earth to orbit the sun hundreds of years before the astronomers smart. His calculation was time taken by earth to orbit the sun :(5th century) 365.258756484 days. ABC model A model to explain the gen etic control of floral organ determination during flower development. It proposes that the four principal organs-sepals, petals, stamens, and carpels-are specified by organ identity genes belonging to three classes: A, B, and C. The organs are arranged in four concentric whorls, and their identity is determined according to which combinations of genes are expressed in each whorl. Class A genes alone specify the outermost whorl of sepals; the forma tion of petals depends on activation of both class A and B genes; stamens are specified by class B and C genes acting together; and the innermost whorl of carpels is deter mined by class C genes alone.
The model was based on observations of mutant flowers in the thale cress (*Arabidopsis thaliana). Mutations in these genes cause the trans formation of one flower organ into another (i.e. homeosis); for example, a class B mutation causes sepals to develop instead of petals, and carpels instead of stamens. The genes corresponding to these homeotic mutations are now known to be *MADS box genes that encode transcription factors, cap able of activating different target genes de pending on what other transcription factors act with them.

compounds based on the general formula C.(Hâ‚‚O). The simplest carbohydrates are the *sugars (saccharides), including glucose and sucrose. *Polysaccharides are carbohy drates of much greater molecular weight and complexity; examples are starch, glyco gen, and cellulose. Carbohydrates perform many vital roles in living organisms. Sugars, notably glucose, and their derivatives are essential intermediates in the conversion of food to energy. Starch and other polysac charides serve as energy stores in plants, particularly in seeds, tubers, etc., which pro vide a major energy source for animals, in cluding humans. Cellulose, lignin, and others form the supporting cell walls and woody tissue of plants. Chitin is a structural polysaccharide found in the body shells of many invertebrate animals.
Carbohydrates also occur in the surface coat of animal cells and in bacterial cell walls. A tubular organ in animals that is divided into a series of zones specialized for the ingestion, *digestion, and *absorption of food and for the elimination of indigestible material (see illustration). In most animals the canal has two openings, the mouth (for the intake of food) and the *anus (for the elimination of waste). Simple animals, such as cnidarians (e.g. Hydra and jellyfish) and flatworms, have only one opening to their alimentary canal, which must serve both functions.
asexual reproduction Reproduction in which new individuals are produced from a single parent without the formation of gametes. It occurs chiefly in lower animals, microorganisms, and plants. In micro organisms and lower animals the chief methods are *fission (e.g. in protists), *frag mentation (e.g. in some aquatic annelid worms), and *budding (e.g. in cnidarians and yeasts).
The principal methods of asex ual reproduction in plants are by *vegeta tive propagation (e.g. bulbs, corms, tubers) and by the formation of *spores. Spore for mation occurs in mosses, ferns, and other plants showing alternation of generations, as a dormant stage between sporophyte and gametophyte, and in some algae and fungi, to produce replicas of the organism.
