I live in Delhi. It is my home town. It is one of the largest cities of India. Many historical buildings are found here. It has great historical importance. The city has survived many great wars and rebellions. Delhi is expanding very fast. More and more new colonies are coming up. The roads are always full of pedestrians. Tongas, cars, scooters, passenger buses, school buses and rickshaws are to be seen everywhere. There is hustle and bustle everywhere. Long queues at bus stops, milk booths and cinema halls are very common. Delhi is a big business and an educational centre. Hundreds of factories employ thousands of workers. Many cottage industries have also come up and produce several kinds of goods. There are hundreds of schools and many colleages in Delhi. Many students study in these schools and colleges. There are also many engineering and medical colleges. Delhi also has many more...

The earliest known breast implant was undertaken in 1895 by Austrian surgeon Vincenz Czerny (1842-1916). Czerny transplanted a large lipoma (a benign tumor composed of fatty tissue) from a patient's flank to create new breasts in a woman who had undergone a mastectomy. Details of the outcome went unrecorded. In the early twentieth century paraffin-wax injections were used to augment breast size, but discontinued due to disastrous complications such as "wax cancer." Other substances tried included ivory, glass balls, ground rubber, and ox cartilage. In the 1920s transplants of fatty tissue were attempted, where fat was surgically removed from the abdomen and buttock area and transferred to the breasts. The procedure was unsuccessful since the body quickly absorbed the fat, leaving the breasts in a lumpy, asymmetrical condition. However, modern transplants using the patient's own fat or muscle tissue are now much more likely to produce good results. Otherwise, there more...

"Damn the torpedoes.... Captain Crayton, go ahead! Joucett, full speed!" Admiral David Farragut, Battle of Mobile Bay, 1864 Despite its notoriety as a naval weapon, the first modern torpedo was developed in landlocked Austria,  or rather by a retired army officer in what was then the Austrian Empire stretching down to the Adriatic Sea. In 1864 Giovanni Luppis (1813-1875) presented his idea of using small, unmanned boats carrying explosives against enemy ships to Robert Whitehead (1823-1905), an English engineer producing steam engines for the Austrian Navy, Similar devices (spar torpedoes) were also employed in the American Civil War taking place at the same time. However, those contraptions consisted of manually driven steam launches with explosives hanging from a long pole. In order to set them off the crew would ram the end of the spar into the target vessel and then back off again, thus pulling a mechanical trigger by more...

If I were the Prime Minister of India. My first priority will be to remove unemployment. This will need complete reformation of education system. The education should be employment oriented Instead of examination oriented. The education up to Sr. Sec. or its equivalent would be compulsory and free throughout the country.  This would be my preference that the deserving students must get free education up to college level without any reservation on the basis of minority, regionalism and caste. Unemployment allowance would be given to educated youth. Maintenance of law and order is as important as education. It would be my prime duty to provide security to people of life and property. The properties of those people would be confiscated who give shelter to terrorists, extremists and secessionists. Those people will be shortly tried and capital punishment will be awarded to them so that others may take a lesson from more...

Astronomers observe light from stars many light years away and yet the thin atmosphere that surrounds Earth can play havoc with their results. Small volumes of the atmosphere have different temperatures and densities; they move around and this turbulence causes incoming light to change direction. The change in direction shows up as distortions in the data and can either render measurements useless or make their interpretation difficult. Observatories are often built on high mountains to limit the thickness of atmosphere the light needs to travel through. However, for the most detailed projects the thinnest atmosphere is still enough to cause problems. U.S. astronomer Horace Babcock (1912-2003) devised an optical system in 1953 that could adapt to the changes and correct the errors in real time. Although his design gave hope to toiling astronomers, it was not used until the 1990s when computers could keep up with the speed of the more...

"The ancient Greeks used dugouts and called them monooxylon, which means 'single tree.'" John Crandall, Dugout Canoes Sometimes there is no real need to be clever, or complex, or even particularly sophisticated when it comes to inventions. Sometimes simple wins. This is definitely the case with the dugout canoe. The people of 7500 B.C.E. needed a way to travel on water, but many of the materials used in the very earliest boatbuilding still lay a long way ahead in the future. So they came up with a simple answer using the technology that was accessible to them. The dugout canoe is, in its most basic terms, a hollowed-out log, nothing more than a tree trunk laid down on its side and its interior removed. All that was required was that the hollowed log had to be big enough for at least one person to sit inside, and the wood had more...

“I have no quarrel with you, good Sir Knight, but I must cross this bridge" King Arthur, Monty Python and the Holy Grail (1975) Primitive suspension bridges, in the form of vines and fiber ropes, have been used for many thousands of years throughout Asia, Africa, and South America, such as those by the Incas. It is thought that the iron chain first replaced these frailer materials in China inc. 100. The walkways of early catenary bridges were directly fixed onto the chains that spanned a valley, but in fourth-century India the road deck was instead suspended from the main cables to create a horizontal pathway that was more easily negotiable than its sloping predecessors. Basic suspension bridges were used in military campaigns in Europe, but the first permanent example in the West was a primitive catenary bridge built over England's River Tees circa 1741. The idea caught on in more...

The environment means the natural surroundings that we live in. This includes the trees, the plants, animals, mountains, rivers, oceans, sky, etc. The nature around us is the very essence of our survival and sustenance. Therefore it is the responsibility of every citizen of the world to preserve the environment and keep it safe as there are efforts to destruct it from many sources. Our earth abounds in natural resources and therefore we have no right to destroy them. Man does not realize that his attitude towards nature will one day make him pay a very heavy price. Man continues to pollute the environment. There is an increase in air pollution because of the growing number of vehicles on roads. The rivers are polluted because factories and houses throw their waste material into the river. Rivers are getting choked with silt, sewage and other pollutants. Factories processing chemical emit poisonous more...

The precise year of the hammock's invention is impossible to tell, but estimates of 1000 B.C.E. are considered reasonable, with the Mayan Indians most often credited with the invention. However, there is no evidence for this, and the hammock's creation is often attributed to a later inventor. In Greece, Alcibiades (c. 450-404 B.C.E.) was a student of Socrates, and some sources attribute its invention to him. Western European society was first introduced to the hammock in 1492 when Christopher Columbus returned from the Bahamas where he had found the native people resting and sleeping in them. He took some hammocks back to Europe and within a century or so they were standard issue for European sailors. In the cramped ships of the time their value was obvious, as they could be stowed away or hooked up for use almost instantly. More than any other form of bed, they allowed sailors more...
