Parenting has become the most talked about matter of fact in the present situation. Parents are those who nature a  child in a rightful manner and guide him to lead a proper life. There was time when there was joint family system in our country. In those set-up the responsibilities of parents were not so much prominent as it is today because now parents are solely responsible for the brought up of a child. But time has become so tough for the parents that they hardly spare time for their child. It has created a crises in our developing society. Parenting has become a mystery and people are trying to find out the ways of successful parenting.  It has always been a concept that family is the first school for a child. A child begins to learn everything from his mother, father and the people who surround him. Parents make more...

What does the term 'Information Technology' really mean ? Information technology is that technology by which the information is processed, communicated, exhibited and retrieved in a fast, error-free and proper-way. Information  technology is a technology in which both telecommunication and  computer technologies work together to provide Information. Today's world is the world of information and telecommunication. Everyday new technology and inventions are being made in the area of information, processing and travelling. There is hardly any area which had not been affected by this. Due to all this, the word distance sounds ironical in present day context. The whole world has become a small place today. Any information can be exchanged by people in few seconds and that, too, in proper and effective way without any loss of data while it is being processed. On the one hand, all these different ways of telecommunication and information exchange have highlighted the more...

Imagine a world where broadband did not exist. Without this high-speed data transfer, would the Internet still be the hub of information, pictures, movie , and business opportunities it is today? The fast connection speeds required the invention of the cable modem, and the man who did that was Iranian-born American electrical engineer Rouzbeh Yassini (b. 1958). Yassini worked for General Electric in 1981 building television receivers. To understand how the signals flowed, he took home television sets and dismantled them to see how they functioned. This knowledge proved useful when in 1986 he joined Proteon, a data- networking company that used a network cable called "twisted pair" to carry data. Despite being told that video and data did not mix, Yassini realized right from the beginning that he could employ the same coaxial wire that carried cable television into people's homes to deliver other information as well. In 1990 more...

French mechanical engineer Eugene Houdry (1892-1962) is probably best known for inventing a process for "cracking" crude oil and turning it into high-octane gasoline—otherwise known as the Houdry process. However, he is also credited with inventing the first catalytic converter for cleaning up car exhaust fumes. Houdry had an avid interest in all things automotive and enjoyed car racing. This made him acutely aware of the need for high-performance fuels in engines, and he developed a way to make high- octane fuels from petroleum using what is known as a catalyst. A catalyst is a substance that can instigate or speed up a chemical reaction, without itself being changed during the process. In the 1950s, early studies about smog in Los Angeles were published and Houdry became concerned about the effect of harmful chemicals in exhaust fumes. The main .products from car exhausts are carbon dioxide, nitrogen, and water vapor, more...

"Tempoi parendum. [One should be compliant with the times.]" Maxim of Theodosius II The tempo of a piece of music, that is, the number of beats per minute, can be established using a metronome, a type of compact, adjustable, loud clock. The most common type is powered by simple clockwork and has a vertical metal rod that swings from side to side making a loud clicking sound at every swing. The rate of swing can be adjusted by moving a small weight up or down the swinging bar. Up decreases the tempo, and down increases it. This helps musicians not only establish the intended beat, but also maintain it throughout a musical piece. The first metronome was made in 1696 by the Parisian Etienne Loulie (1654-1702). This required a single-weighted pendulum, similar to that of a grandfather clock. It had no clock escapement to maintain the pendulum in motion, so more...

At the beginning of the twentieth century, New York City may have been very picturesque in the snow and ice, however, it was not much fun if you were trying to drive a trolley car at the time. Then the only solution was for the driver to keep the windshield up and constantly get out every few minutes to clear the slush that built up on the windshield. Mary Anderson (1866-1953) was visiting New York when she noticed this predicament, and when she returned home she jotted down a solution. Her device was a swinging arm with a rubber blade that is moved by a lever inside the car, keeping the driver warm and the window clear. In 1903 she received a patent for the novel device, but when she tried to sell it in 1905 nobody was interested. It was still three years before the Ford Model T and more...

In 1969 a company called Bolt Barenek and Newman won the contract to develop a communication network called ARPANET that would enable scientists and researchers to use each other's computer facilities. During its development, an engineer named Ray Tomlinson (b. 1941) started to experiment with the coding of two programs. SNDMSG allowed members of the same network to exchange messages among one another, whereas CPYNET allowed file transfers to occur between two separate networks. It occurred to Tomlinson that by combining the two he could create a system that would make message transfer possible between different users of independent networks. One of the most significant decisions made by Tomlinson was his choice of the @ symbol to separate the user's name from the host network name. It was a fairly logical choice, but one that revived the rather esoteric symbol and saved it from the brink of linguistic extinction. Unaware more...

India is a hot country. But it has an ocean in the south. In summer, the air becomes very hot. It rises very high in the sky. To take its place winds come from south. They are full of moisture. They strike against the mountains and cause rains. These winds are called monsoons. They bring a large quantity of rains for our country. The rainy season lasts from July to September. Sometimes it rains heavily for days together. We cannot see the sun. The clouds run in the sky freely they are of dark colour. Sometimes they are very thick. They make it dark even in the day. When the first rain fails, the whole earth becomes happy. Everything is mad with joy the frogs croak in the rain water very loudly. Sometimes we find it difficult to sleep soundly on account of their noise. We can see the peacock more...

The ability to use a computer to fully map out product or building plans was an effect of the microchip revolution. CAD (Computer Aided Design) completely changed the design process for almost all industries, making it easier and simpler to plan, refine, and optimize product designs of almost any size. The initial development of the CAD system began in the late 1950s, when Dr. Patrick Hanratty helped to design, first a system called PRONTO, a pioneering numerical programming tool, and then the DAC (Design Automated by Computer) system. This was the first computer graphics package that allowed user interactivity with the designs and was the forerunner to the beginning of the CAD system. The turning point came in 1963 with the unveiling of the SKETCHPAD system by Ivan Sutherland (b. 1938). Developed in the United States at the Massachusetts Institute of Technology for the first time the computer program allowed more...

India is basically an agricultural country where about three fourth of its population live in the villages. The villages have their own charms. They are generally cut off from the Cities and have a totally different kind of life. There are charms in village life. There is the pleasant rising with the morning star glittering in the sky. After sunrise the cattle are taken to the fields for ploughing. We can hear the bleating of the lambs and the chirping of the birds. How fascinating their sounds are! They leave a soothing effect on the mind. Apart from this, the flowing of the river with a murmuring sound, the beauty of the greenery of fields around are the various pleasures that abound in the countryside. The peasants work in their fields all day in sun or rain. Sometimes it seems that they play on the lap of Mother Earth, notice more...
