Science had made rapid progress in the recent years. Much of our comfort in life is due to the work of famous scientists. We turn a switch on and the whole of the building is illuminated with a dazzling light. This is just like Aladdin’s magic lamp.

It has given us discoveries and inventions that have revolutionised the ways of our life and our outlook in general. Science with its invention of aeroplanes and ships has made us the lord of air and water. We fly in the air and sail on the bosom of the seas and oceans.

Science has harnessed the forces of nature. The river valleys are dammed up to arrest water and then to make it available for irrigation through the network of canals. The deserts are changed into fertile arable fields. The waterfalls made artificially are generating electricity for varied uses 

Train, ships, vehicles and aeroplanes are the gift of science. They have made transport and journey easy, quick and comfortable. Long journeys that used to take days and weeks can now be covered in very short periods of time. 

Science has given us weapons for safety; television, radio and cinema for entertainment. It has controlled the most fatal diseases. So the wonders of science are uncountable. There is no sphere in life in which science has not brought a change. Today we have many things of which our ancestors had never dreamt.

Electronic stoves cook our meal and X-rays tell us where a bullet is embedded in our body. Electric shocks are given to men of deranged brains. Radium is no less important than electricity. A tiny particle of it can drive our trains. It also provides a cure against deadly diseases, such as cancer. Exposure to its rays burns up the  disease. Then atomic  energy is another discovery of science. If put to constructive use it is a boon. 

Science has given eyes to the blind and ears to the deaf. Science has made serious operations a reality. Transplantation of heart has become a possibility. Thus we see that science is a double edged weapon. It is useful if we use it for our comfort and convenience.

 Science has dazzled humanity. It has turned impossibilities into possibilities. Time and distance have killed. Agriculture has been considerably mechanised. There is a remarkable development of industry. The radio brings to us the songs of the greatest musicians of the world. The television enables us not only to hear distant voices, but also to se distant functions, matches and other sights. Many diseases have been conquered. Germ die, victims live.

But there is another sight of the picture. Science has invented atom bombs and hydrogen bombs which destroy millions in a split second. They let loose death and destruction on the head of humanity. Science has, on the one hand, given us numerous comforts and amenities but, on the other hand, it is also driving us into the valley of death. It is signing the death warrant of humanity. It is murdering the humanity.

Man has become the slave of machine. One factory throws thousands of laborers out of work. Unemployment is ever on the increase. Gandhiji favoured not mass production of mills and factories but production by the masses.

Another curse of science is that it has made man godless. Science has fed our body but starved our soul. How does man benefit himself if he gains the whole world but loses his soul in the game? It has destroyed man’s character and personality. Man has lost neighborliness, sympathy, love and fellow feeling. He has become a brute. He has become mad. Science has created more problems than it has solved. It has brought comforts, but it also brought death with it. Science is the murderer. A murderer cannot be exorcised on the ground that before killing his victim, he feasted him or gave him comforts. Science has placed untold power in the hands of man and man misuses it. The memory of death and large scale destruction that followed in the two beautiful cities of Hiroshima and Nagasaki of Japan is still fresh in our memory. The same story may be repeated in a much more virulent form. 

To sum up, we must use science for the good of humanity and not for its destruction.

 Exercise is good for health. It keeps us fit and healthy. It keeps the diseases away. It gives us energy and strength. We should take exercise daily.

There are many types of exercises. Swimming, walking, jogging, cycling, swinging, running are different forms of exercise. Different people have different choice of exercises. Some people like light exercise. Many choose running and swimming as exercise. Some people join gym for regular and proper exercise.

Modern life is very fast. People do not find time for exercise. This is not good for health. We should always do exercise. We should walk on foot. We use scooter, bicycle or motor cycle even for a short distance. This makes our body lazy.

The best way to keep our body healthy is through exercise. Walking is the easiest exercise. Morning walk is the most useful. Morning is the best time to take exercise.

 Radio is a means of mass communication. It is one of the cheapest media of entertainment and information. It is still a popular means of mass media. Both old and young, educated and uneducated, rich and poor listen to the radio with great interest. It is equally popular in villages and metro cities.

Radio is a powerful means of information and entertainment. We have speeches, songs, news and debate and discussion. Even a poor man can have a radio set. It is a very cheap and so everybody can afford it. It helps to create public awareness. A village farmer gets information about latest technology of farming through radio. Radio helps him to learn about the weather condition. An illiterate woman can learn through radio about her household activities. Radio is important for students. They learn new things with the help of radio. Thus, radio holds great importance for a country like India.

 Trees are valuable natural resources. They are the gift of nature. They provide shelter. They give us fruit. They are the source of herbs and medicine. Trees give us wood also.

Trees are very helpful to man. They control pollution. They prevent soil from  erosion. They maintain the fertility of soil. They bring rains. Rains are very important for India. India is an agricultural country. They give us food, fruits, etc. Papers are made from wood pulp. We write on the papers. Rubber, lac, silk, etc.  are produced from the trees. These things have great commercial value.

Trees give us fresh air. Fresh air is good for health. They absorb the carbon dioxide and give out oxygen. We breathe in oxygen. Trees provide shelter to birds and animals. Trees help to check floods. Floods are great natural calamity. So, we should protect trees. We should plant more and more trees.

Some trees like mahogany, sal and rosewood give us hard timber to make furniture and doors, etc. Some trees like poplar give us soft wood to make corks. Leaves, branches and fruits of many trees have medicinal value.

 Telephone is a gift of science. It is the fastest means of communication. We can talk to a person sitting thousands of kilometres away. The communication is held with the help of wires. There is a wide network of wires. Telephone is becoming very popular. Today, even a common man can afford this.

Telephone was invented by great scientist Alexander Graham Bell in 1875. This invention proved to be a great boon to mankind. It became popular all over the world. Communication became fast.  Before it’s invention, communication was very difficult. It took many days for the message to reach its destination. But telephone has reduced the time of giving and receiving messages. Within a minute, a man can have a contact with a person sitting too far.

Telephone has greatly helped people. It has helped in trade and business. It has contributed to the growth of education. Now the telephone facilities are available in the remote villages.

 Computer is an electronic machine. It is very common these days. It can be seen everywhere. It is widely used in banks, post offices, offices, factories, schools, colleges, shops and malls.

Computer works very fast. It’s results are very quick. Computer is superior to human brain. It remembers masses of data and performs calculations at lightning speed. It is highly efficient. Life cannot be imagined without computer.

Computers are very useful to school students. They help students learn new techniques of study, graphic designs, games and other useful applications. They are also helpful for office executives and college students. They help the librarians in efficient management of libraries. They are used in space science and laboratories. Any information can be found by surfing internet. Computers have become a necessity today.

Students should learn computers. They are easy to learn. They help in their education. They enrich their knowledge.

 Pollution is a serious problem. It is a cause of great concern for mankind.

Pollution is of many kinds. They are air pollution, water pollution, noise pollution and soil pollution. With the growth of population, pollution is also increasing. Industries have added greatly to pollution. The air we breathe is filled with smoke. Water is polluted.

Towns and cities are growing fast. Population is increasing. New factories are being set up. Trees are being cut. The wastes of the factories go into the rivers. They cause water pollution. Household wastes also fall in the rivers. They also make source of water dirty.

The number of buses, cars, scooters and motorcycles is multiplying. They emit poisonous gases. The smoke of factories also adds to the air pollution. Uses of loudspeakers and DJs create noise pollution.

We should be aware of these problems. We should plant more and more trees and eco-friendly habits. Lf we do not pay proper attention to the problem of pollution, the life on this Earth will become difficult. Health standard of people will fall.

 India is a democratic country. As per the constitution, the rank of President is the highest. Smt Pratibha Patil is the first woman President of India.

 More than fifty years ago, traveling was dangerous and difficult because modern means of transport such as trains, buses, cars and aeroplanes were very rare. But with the advancement in the means of transport, traveling has become a means of education, and is no longer limited to books or the teachers.

Education here does not mean purely bookish knowledge. Education here is referred to in its wider sense. It means the complete understanding of the different ways in which our society and the world work. It includes the field of industry, commerce, agriculture and thousands of other skills. It is only by coming in contact with larger sections of humanity, in different parts of the world, that we can receive the right type of education.

Bookish knowledge has its own importance. It give us the basic knowledge of human activities. We learn the theoretical details. But that knowledge becomes complete by gaining practical knowledge. It is, therefore, quite essential that we move from place to place. Only traveling can help us give a practical shape to the knowledge we have obtained from books. Therefore traveling is essential for the development of intellectual, moral and even commercial aspect of our life.

Students must travel now and then to know for themselves how the world is going. Businessman also have to travel to acquire knowledge of the business techniques. It also helps them to establish contacts with their colleagues at other places. Even doctors and lawyers must travel to improve the quality of their work.

 There is a great controversy going on in the world now a days about peace in the world. Some people believe that there can be permanent peace in the world. On the other hand some think that permanent peace is an impossibility. Let us examine these views critically.

There are some thinkers who believe that the world can have permanent peace, because science has developed to such an extent that the only alternative to peace is the total extinction of the world. As war will be suicidal to human race, there will not be any world war.

This view is based upon the sincere desire for living and letting others live. These people say that a man is a social being. Somehow or the other, the leaders of the world will not commit the folly of leading the world towards destruction.

These are some thinkers who are of the opinion that in our world permanent peace is not possible. According to professor C.E.M. Joad, our world has reached that stage, where even a single event may blaze the whole of it. The antagonistic attitude of the democratic world towards the communist block and vice versa resulted in the mad race of armaments. Various kinds of destructive weapons like atom bombs, hydrogen bombs and rockets are manufactured on such a wide scale that even rich countries have now no money left for useful, social, and political works.

In the UNO issues are discussed and voted on the basis of groupism. None cares for the honest, sincere and practical solution of the problem. Hence, it is foolish to think that there will be cessation of war. And if once there is a war, it will surely develop into a world war which means the destruction of the world.

If we think over these views seriously, we come to know that there is a particle truth in each of them and each view is one sided, as it is impossible to believe that balance of power will always remain with two antagonistic blocks. In the same way, it is also unbelievable that politicians of the world are so insane that an ordinary fighting between any two countries will lead to a world war. For example, in the case of Korea, Iran, Iraq, and Kuwait, the situation was not allowed to take a serious turn, though it is also true that the division of the world into two camps is certainly not in the interest of permanent peace.

 There are many problems before our country today. The problem of unemployment is one of  them. It is a serious problem. It implies an involuntary idleness. The individual who has no means of earning his bread by means of labour becomes a nuisance to the society. Unless every one is given work, the problem cannot be solved.

There are many causes of unemployment. The first cause is that the system of our education is defective. Much importance is given to theoretical and literary education. The practical side is almost neglected. The result is that the schools and colleges have become machines producing unemployed persons. When boy comes out of the school, he find himself unemployed. Whenever he goes, he finds the doors closed for him. In the end, he becomes desperate.

Machines are also responsible for unemployment. They have destroyed cottage industries which were a source of income to poor people. The result is that a man gets lesser amount of acres of land than his father used to have. Generally, it is seen that in villages there is no work to do when the farmers are unoccupied. 

In order to remove unemployment, our government should do her best; as unemployed citizens generally become a prey to the informal ways of living. The state which cannot provide employment to her people can never claim to be a welfare state.

The system of education should be changed. Emphasis should be laid on the importance of manual labour. Special attention should be paid to technical education. Cottage and small industries should be encouraged and money should be made available to the villagers on a nominal interest to run their industries. Some sort of arrangement should be made so that the landless workers must have some land to cultivate. Import of foreign goods should be stopped and Indian industries should be patronised.

Though our government is fully alive to the problem, yet any immediate solution is nowhere in sight. Unless the problem is solved satisfactorily, all talks of welfare state and Ramraj are meaningless.
