This is the age of science. Science has made man’s life and living more comfortable. It has solved the problems of time and distance. It has made the world happier. It has made life easier and worth living. In olden days our forefathers had no benefit of scientific inventions. They used to go from one place to another on foot or in bullock carts. They used to light earthen lamps in their houses. Radio, telephone and television were unknown to them. There were no aeroplanes in those days and the idea of the conquest of the moon was considered a cock and bull story.Science has revolutionised human life and has done great service to humanity. In the field of transport, now we have cars, buses, tramways, railways, aeroplanes and ships. In a car we can travel with great comfort. Buses are an important means of public transport these days. Railways are the cheapest and safest means of transport. They pass through deserts and forests and carry passengers and goods to far off destinations. Aeroplanes are the fastest means of transport. There are supersonic aeroplanes, which fly faster than sound. Now you can have your breakfast in Delhi and your lunch in London. There are large ships which carry passengers and goods across the seas and oceans. Time and distances are no problem. The world has grown smaller. The credit for all these achievements goes to science.Science has influenced our means of communications as well in a big way. In the olden days messages took months to reach distant places. Messengers and horse-riders carried messages. But now we have telephones, wireless, radios and televisions. On a telephone you can talk to your friends, relatives and business partners at a distant place in half a minute. With the help of wireless apparatus, messages may be conveyed to far off places in no time. Radios give us news from all the corners of the world. They are a source of enjoyment and recreation as well. On the television screen you can see happenings of far off lands. These marvels of science have changed our way of life.Our life has become more comfortable. In the summer electric fans provide us cool breezes. Coolers and air conditioners cool our home, offices and public halls and make our life more comfortable. Refrigerators prepare ice-cream forus. In winter we use room-heaters to warm our rooms. We use electric iron to press our clothes. With the help of water-heater we get hot water for our wash and bath. In our kitchen we use electric stoves, hot plates and electric kettles. These apparatuses make cooking easier. Call-bells in our houses are operated by electricity. Electric bulbs light our houses and streets. A large number of factories are run by electric power.Science has conquered diseases. Wonderful medicines have been invented to prevent and cure diseases. There are sulpha drugs to cure many dreadful diseases. Medicines for treating tuberculosis successfully have been invented. Tuberculosis is no longer an incurable disease. The discovery of X-ray and radium has made new advances in the field of medicine. Now defects, deformations, tumours and injuries inside the body of a man can be found out with the help of X-rays and radium. Another grand success in this direction is plastic surgery. Now it has become possible to transplant various parts of the human body such as kidneys and hearts, etc,Vaccination has made small-pox a thing of the past. Injections and inoculations work as a guarantee against an attack of cholera, plague or typhoid. In olden days epidemics used to take a heavy toll of life, but now scientific methods and medicines have brought them under control.Atomic power is being used to run huge factories. Atomic power stations are becoming very popular. Scientists in the atomic field have made valuable contributions to medical science. Their researches have resulted in easy detection and Cure of certain diseases.Science has made our defence more effective. Many new„ ‘. j and weapons have been invented for the use of our, defence forces. They have increased our defence preparedness.Man’s life has become easier, happier and more comfor-e( because of scientific machines which save labour and do 9|l in less time. It is with the help of science that man reached the moon. Several successful flights have been to this only satellite of our world.ioicntific appliances are doing almost every thing for ind so man can spare and utilise his energies and time |her und nobler achievements. Science has made the free from superstitions and has made man more ! It has taken the world community out of the shell nationalism and has opened up new vistas of truthth« development of nuclear weapons and the devasta-’ by the use of atomic bombs (used for the first tJ I A, against Japan) have sullied the fair name of collected rock samples from the surface of the moon. These spaceships, robot and even the carriage named Lunokhod, were being controlled from the earth. Afterwards three Russian cosmonauts lost their lives in Soyuz, a Russian spaceship. The Russian scientists have successfully carried out many miraculous experiments in the field of space flight.
The Soviet Union’s two cosmonauts linked up with the orbiting space station Salyut 4, then went aboard to carry out experiments. In January 1975, Lt. Col. Alexei Gubarev and Flight Engineer Grechko—both aged 45—carried out the docking of their Soyuz 17 space craft and the space station in two stages. The initial approach was controlled automatically by equipment aboard Soyuz, But the cosmonauts used manual control from a distance of 100 metres to bring the two crafts together and perform the actual link up.
Another important event in this direction was the docking of American Apollo 17 and Soviet Soyuz 19 spaceships in the orbit on the 18th July 1975. Astronaut Thomas Stafford and cosmonaut Alexei Leonov met in the docking tunnel between the two ships to exchange greetings and the flags of their nations. The joint U.S.A.-U.S.S.R. space experiment has opened new vistas of space research and technology.
In August 1976 the Soviet cosmonauts returned to earth after 48 days on board the orbiting space station Salyut. The Soviet cosmonauts aboard Soyuz 22, collected information about geological and geographical characteristics of outer space and studied the effects of weightlessness on the formation of sprouts on higher plants. Other landmarks in space travel are the journeys performed by Soyuz 24, and U. S. space shuttle ‘Enterprise’ in February 1977.
Though man has conquered the moon, he is not yet satisfied-His efforts to conquer other planets are afoot. There has been rapid progress and development in the field of space research and technology. Many valuable scientific facts about Venus have been successfully obtained by landing certain scientific apparatus on the planet. The American spaceships Mariners have ventured to make certain discoveries and have taken certain photographs of Mars. Scientists are busy finding out whether there is any life or vegetation on Mars. Looking to these researches and advances in the field of space travel, it is hoped that man may land on Venus and Mars as well.
