The Pen is Mightier than the Sword


This proverb means that a writer is more powerful than a fighter. Men like Napoleon or Alexander the great, might be able to impress the people of their times. But the influence of a writer lasts longer. The French revolution is a milestone in the history of mankind. It paved the way for drastic changes in many parts of the world. In a sense we can say that writers like Voltaire and Rousseau were able to shape the destiny of nations. Napoleon may be forgotten. Nelson may be forgotten. But Shakespeare will be remembered for ever. Homer will be remembered for ever for his contribution to our culture. Let us be proud of them.

Role of Scientist

The phenomenal progress of Science has brought about a revolution of development and prosperity in the modern age. Mankind is today living an entirely different life to what our forefathers used to live. The outlook of humanity has changed. Science has proved to be a great achievement for humanity and it has come to relieve mankind from all sufferings, pains, poverty and diseases. It is serving humanity in all walks of life. However, Science has also done great disservice to mankind in the field of armaments and destructive effects of war.
Science has helped man to increase production in various ways. Science has helped in growing textile and paper industries, sugar and fertilizer industries. Countries which are industrially advanced are most powerful and rich today. Rapid industrialization of a country is the slogan of humanity. Without Science, we cannot grow enough for feeding the increasing population. Extensive and intensive agriculture has been made possible by Science as a boon to the entire humanity. New agricultural machines and disease resistant varieties of seeds are some of the contributions to agricultural sector. The deserts of yesterday have been converted into major granaries of the world today by Science.
For humanity, time and distance have no sense today. Science has made man to cancer distances within seconds and minutes. The world has got narrowed down to a global. Highly advanced industrial economy has replaced the self-sufficient village economy thus making a change in every walk of life. If the scientists provide the technical know – how to underdeveloped countries of the world in respect of development in various fields, then definitely it will be a great service to entire man kind.
Science has made human beings reach other planets and conduct research work there. Various satellites made by man are moving around the earth. Man has landed on the moon. Science has given humanity very effective means of propaganda. Powerful means of communication like television, radio, the cinema and internet have made the entire world aware of latest technology – information and news. It is possible to create public opinion at the same time through video – conferencing. Man has begun to use his knowledge of Science for peaceful purposes. It is wished that science will enable man to remove horros of war completely from the mind of humanity.
In spite of all contributions of Science towards welfare of mankind, there are various disadvantages of Science. In many industries, human labour has been replaced by advanced machines, thereby leading to unemployment. Often there are instances of leakage of poisonous gases from factories either due to technical snag or human error. But it is mankind that is affected. Science has given atom bombs which make the entire mankind live in a constant fear of destruction and misery. Limitation of Science does not teach when to use the atom for curing purposes or when to kill with it. Threat of universal destruction always hangs over human being.
Another losing aspect of humanity due to Science is its spirit. Science has made man to forget the spirit. It is the root cause of all evils. With its breath – taking discoveries and inventions day – by –day, and with a promise of nothing for the spirit, man no longer cares for the development and upliftment of his spirit. Man has lost faith in religion. Religion is decaying along with sad plight of our art and culture. Science has made the man of modern humanity a moral dwarf. Science has no power to uplift man and inspire him with noble ideas. Truly Science has given power but not wisdom.
Scientists all over the world should be encouraged to carry on such research programmes through which they can promote welfare and prosperity of mankind and save it from complete extinction due to adverse impact of nuclear energy etc. Modern scientists should take it as their responsibility to divert the use of nuclear energy into channels which would make this world a safer place and better life for human being to live.

Atomic Power and Its Impact

It was America which tested the atom bomb in the deserts of Mexico, but Otto Habur, a German scientist was the first to succeed in making the atom bomb by splitting the atom. For this he got the Nobel Prize for 1944 – 45. Later on, America dropped two atom bombs on Japan to bring the World War II to an end. The first was dropped on Hiroshima and the second on Nagasaki on 6th and 9th August 1945, respectively. Both the cities were ruined. America came out as the mightiest country of the world.
Now the atom bomb is the thing of the past. Hydrogen bomb which is made by fusion of hydrogen atom into helium is many times more powerful than the atom bomb. And in this series most destructive (powerful) is the neutron bomb.
Today, the world is sitting on a volcano. The fear of use of the bomb in war has started a mad race among all the nations, especially those who are rich, can invest huge amount on nuclear weapons. Dr. Einstein, the world famous scientist once said that the fourth war, at all it breaks out, will be fought with bricks and stones, because a third world war will bring everything in the world to ashes. Therefore, it is a challenge to mankind. Either man should put an end to war or war will end him.
The association of atomic power with destruction has all along raised the question whether atomic energy should be developed at all. After the incidents of Hiroshima and Nagasaki, man has begun looking on atomic power with horror and suspicion.
His horror is certainly well founded. The superpowers like America, Russia, Germany, France, China etc. have stockpiled deadly atomic weapons in their arsenals. There is tension and suspicion, distrust and fear of each other. If a war starts between the nuclear powers, atomic or nuclear weapons may certainly be used and then mankind will witness a destruction of all the fruits of civilization and culture, all beautiful things which science has given for our comforts, well being, pleasures will be wiped out of existence. Instead of bustling of life there will be deadly silence of death. All those who love life, its beauty and goodness would like the atomic power to be brought to an end.
India has always opposed the use of atomic energy for the destruction of mankind. Though on May 18, 1974 history was made at Pokhran by exploding the first nuclear device. Then after a gap of 25 years, on May 11 and 13, 1999, India again tested successfully its nuclear power. This has led Pakistan also to test its nuclear power. It also successfully launched in May itself, though both are committed to the use of nuclear energy for peaceful purposes only.
Atomic power harnessed for peaceful purposes can bring enormous benefits to humanity. It can solve the energy problem. Nuclear power can be used for canal excavation, natural gas stimulation, underground mining, oil and extinguishing gas fires. Agricultural production can be increased manifold by making use of radioisotopes. Industrial production will go up. There will be no pollution due to smoke and fumes coming out of chimneys. A revolution can be brought about in the medical science. We know that radium rays are used for treating cancer and other diseases. Atomic energy can be used in place of conventional sources of energy in transport. This will make transport quicker cheaper and more comfortable.

Science in Daily Life

In the history of mankind, advent of Science is the greatest blessing. Science has come to relieve mankind from sufferings, ignorance and to control nature. It has been defined as a systematized body of wisdom and knowledge which can give rise to greater and greater inventions. Science has also been known as a faithful servant of man who serves all his life and as per the orders of man. Science can be harmful if we misure it.
Science has brought about far-reaching changes in every sphere of our daily life. Now everybody can afford to avail the benefits of luxuries and comforts created by Science. Science has made goods cheap and readily available and has brought them within reach of every individual. All kinds of gadgets of music, entertainment and communication have been brought to our door with the help of Science. Surely, the life of man is very different from what it used to be few years back. Truly, Science has given ears to the deaf, eyes to the blind and limbs to the crippled.
In everyday live, we have to communicate with different friends and relatives, various official people and for general purposes. And many people to be contacted can be at very far off distances. However, time and distance both have been conquered by Science. Whether we want to communicate or travel, both are possible within seconds. For communication, we have telephones, mobiles, wireless, E-mail, VSATs and internet etc., For faster traveling, aeroplanes are being used. Railways have made journeys swift, safe and comfortable. Entire world has shrunk into a small family. Modern ships have conquered turbulent waters and are perfectly safe for traveling and transportation of goods.
Health is wealth. This has been made possible with modern machines. Science has invented ways to peep inside the human body to tackle diseases of human beings through X-ray machines. Diseases can easily be detected and various tests conducted within a matter of few seconds. Complicated operations are possible and are successful with the help of equipments and machines invented with the help of Science. Human life would get transformed into new horizons and heights of prosperity when atomic energy is fully utilized for peaceful purposes.
A big contribution of science in our daily life is electricity. Without electricity, there would have been complete darkness after evening hours and no industry could function without the power of electricity. We have been able to control the effects of weather change with electrical energy. All fans, coolers and air-conditioners in summer and all kinds of heating gadgets in winter, functions with the help of electricity. Entertainment through cinema is one of the most remarkable invention of science in our daily life. It provides us cheap and enjoyable pastime and comfort from tensions of daily life. Now each household has television and radios which are the fastest medium of mass communication made possible by Science.
Science is proving to be of great help in our daily life. The world would have come to a standstill without inventions of Science. There is shortage of space everywhere and as such, high – rise buildings are constructed both for commercial and residential purposes. Inventions of lifts working in these buildings have made life very easy. A housewife can cook tast with the help of electricity run kitchen machines. Thus she saves a lot of her cooking time and is able to devote that precious time in many other activities related to family life. The washing of clothes for her has become really an enjoyable game of few minutes. Even she need not run here and there spreading wet clothes for drying. All this is possible with the production of fully automatic washing machines.
In spite of Science as a blessing in our daily life, we remain in constant fear of mass destruction weapons invented by Science. Another disadvantage of science has been the misuse of mass media for propaganda. Sometimes information stories facts are blown out of proportion leading to tension among the masses. Much of communal tension withing the country has been the creation of media. Mass media is used by anti-social elements to spread rumours and false information. Once a story is circulated, it spreads like a forest fire, thanks to mass media. It is certainly upto mankind to utilize the benefits of Science for welfare of all or to indulge in making mass destruction weapons for miseries of future generations. Science can further be utilized to make our daily life more prosperous, comfortable and full of happiness.

Air Transport a Marvelous Gift of Science

Science is a great blessing to mankind. It has transformed our life to a great extent from what it used to be few years back. The triumph of science is seen everywhere. Science has changed the face of the earth, the world has changed more during the past 100 years than during 4000 years before. In fact, we have ceased to look upon trains or motor cars, electric fans or telegraph or radio as marvels of Science. Today, we see the greatest and marvelous gift of Science that is, ‘fly like a bird’ in the open sky. Since long, man was satisfied with buses, trains or even ships. He wanted to fly in the sky like birds. He craved for wings. This desire of man let to the invention of the aeroplane by the Wright brothers in 1903.
Aeroplanes are the gift of Science as mode of air transportation. Science has made traveling a pleasure particularly air travel. Through air travel, Science has spanned the sky, measured the oceans and wrested from nature many of her hidden treasure. It has annihilated time and distance and made the contact with world easier and quicker. Early man used to go from one place to another on foot and then gradually he used animals as beasts of burden. Thus, road transport progressed and then railways and water transport was invented. However, human being was not satisfied with all this. He invented aeroplanes. With air travel, The whole world is well-connected by a network of different airways.
In today’s world, man has become very tast going and is always occupied with many tasks at one time. He wants to save time in every respect, particularly, when he is to travel from one place to the other place. He doesn’t want to waste a single moment in transit. Under such circumstances, it is air transport only which has helped him in a big way.
Air – travel is found to be most comfortable. There are no hindrances and traffic jams as is mostly there in road transport or problems associated with railways. In India, Tata Sons and National Airways began air operations in 1932 with light and single engined aircraft for the purposes of mail transportation. It was only after World War II that full-fledged advanced type of aircraft started operating in India. They connected all important destinations. Then, in 1953, civil air transport was nationalized in India due to financial constraints being faced by the sector. Since then, tremendous progress has been made. Today, there are various domestic and international airlines carrying passengers to different parts in India and to the various parts of the world.
Though air travel is considered as one of the best contributions of Science yet it has got various limitations. Firstly, it is very costly and only the rich people can avail the facility of air transportation. A common man can travel in the train only. Secondly, air travel can be risky and dangerous. This is because if there is any mishap or accident, there is no chance of survival. Accidents prove to be very fatal and loss of life and property in a huge manner. Also the air travel becomes dangerous whenever the weather condition are adverse.
There has been a constant desire of a man to develop more advanced and sophisticated aeroplanes. He has not been deterred by the hazards of accidents in traveling by aeroplanes. Man has seen the importance of aeroplanes in war times. Today, the United States of America has the most sophisticated fighter planes which can destroy enemy camps within seconds and at any time of the day or night. Today wars are won with the strength of air power.
This wonderful invention of Science in recent years has progressed by leaps and bounds. The emphasis is on more speed, safety, passenger – comfort and convenience. There is more and more competition among various airlines to offer the most competitive rates and most convenient timings. The future of air-travel is bound to get brighter in the times ahead. The efforts are being made to make the air transportation more safe and economical through new researches.

Science and Education

The greatest blessing to humanity is the advent of Science for bringing social prosperity through spread of knowledge and education. Science has helped man to the sky, measure the depth of oceans and wrest from nature many of her hidden treasures. In recent times, it has transformed human life beyond all imagination. Through its advanced inventions and discoveries, Science has cast its great effects on social life of the human and removed sufferings, ignorance and hardship. Science has extended the frontiers of knowledge of society in various ways and in various directions. It has enabled man to fight natural calamities and to revolutionise industrial and agricultural processes.
The level of education has greatly improved with the help of Science. Now people are more aware and want to know more and more about the latest happenings all round the world. In the modern era of Science, greater emphasis is being given to television in educational, social and moral spheres. Now it has become possible for man to sit in the cosy confines of his living room and watch the latest happenings of the world from his home. The expantion of education through television has been tremendous. Moreover, it has a great educative value. As on date, there are various programmes run by University Grants Commission to teach various subjects through the media of television. If proper methods are adopted, various subjects like Chemistry, Physics, English, Commerce and Mathematics etc., can be very well taught through television programmes. The students also gain a lot from such lessons taught in the form of pictures relating to various topics.
The subject matter taught on television has a more enduring and effective impression on the minds of the viewers. Further, it is all the output of the experienced teachers who understand the problems faced by students who pursue education along with their jobs or cannot afford to go to a regular college. In a large country like India, where most of the population is uneducated, the role of science in dissemination of education through television cannot be denied.
Science has also contributed the most advanced and well equipped laboratories for students to learn and conduct practicals. The launching of INSAT and other communication satellites in the space has given further fillip to the cause of education. Now the boundary of a state or a country is not the limit to get qualification of a particular university. The student can go through various courses through satellite – run programmes. The greatest and most significant achievement of science in this regard is launching internet. The internet has brought about a big revolution in the world of education and information. The click of the mouse can help him access a world of information in a matter of seconds.
With the help of Science, even the minute details of any kind of information or data is recorded wither on cassettes, disks or printed in any kind of books. The libraries of the schools, colleges and universities are full with latest books and journals on all subjects topic wise. A student can opt to go through any subject either on computer, or by going through a book. He has all the options available with him. Science has given him options to study various new fields in the research and development of science itself.
Science has helped the students to travel all across the world not only for pleasure but to educate himself about various wonders of nature and see historical places. He can avail the facility of cars, trains, ships and aeroplanes and reach his destination in time. Even he can talk to any relative or friend living in any part of the world at any moment of the day or night. Thus he has no tension and can concentrate better on his studies. A student can complete a work of months and years in a matter of hours. Communication and transport have really made the life of students more comfortable.
All other forms of entertainment have been brought to the door of the student by Science, Radio, television and cinema is helping the student in relieving the daily tensions of life by providing him the best and affordable entertainment. Surely, the daily life of students is very different and has improved a lot with the inventions of Science. Truly, Science is unlimited knowledge for a student and is going to be an eternal source of new blessing in the cause of spread of education across all horizons of the world.

Science and Social Prosperity

Science is the greatest blessing to mankind. It has transformed human life, Nothing better could happen in the history of mankind than the advent of Science and great uses of it to the social life of society. Before Science could cast its great effect on social life of humans it was all a world of sufferings, ignorance and hardship. Science came as a blessing to relieve society from suffering and difficulties of daily life. The triumph of Science can be seen in every aspect of daily life. According to a famous writer, Science has changed the face of the earth and the society more during the last 100 years than what it changed in 4000 years before.
Science has helped man to scale the sky, measure the depth of oceans and wrest from nature many of her hidden treasures. Traveling has been made a pleasure by science with the invention of motor cars, trains, ships and aeroplanes it has become easy to travel distance.
No longerman has to wait to meet any friend or relative in trouble at a faroff place. He can just catch the first train or fly like a bird and within minutes see his dear ones. Even he can talk to any relative or friend living in any part of the world at any moment of the day or night. A person can have his morning tea in Delhi and breakfast in Mumbai and lunch in Chennai. The work of months and years can be completed in a beings more prosperous and comfortable.
Science has extended the frontiers of knowledge of society in various ways and in various directions. It has enabled man to fight natural calamities and to revolutionise industrial and agricultural processes. Gone are the days when only the rich could afford the luxuries of modern life. Science has made the goods particularly the electronic gadgets so cheap that they are within the reach of almost every common man. It has enabled industries to produce goods in greater quantities thus making things affordable. Books, music and all other forms of entertainment have been brought to the door of the common man. Radio, television and cinema helps the society in relieving the daily tensions of life by entertainment. The quality of life in society has improved a lot with the inventions of Science.
Science has changed the life of the housewife in our society. Now she need not spend her whole time cooking meals for a big family. Hundreds of modern gadgets have been deviced by science to help the housewife in the kitchen. There are various electric food processors, grinding machines, cookers and ovens. Cooking has become a pleasure with no smoke, dirt or suffocation. The availability of fully automatic washing machines and dishwashers have made life very easy and fast. Now the women can take time from their homes to participate in various other functions of the society and contribute towards common welfare of mankind in general. Science has given time to housewives, to spend it with their children, to study in their leisure time and to handle business or work in offices. It is all sign of social prosperity.
The face and look of society has changed with the developments brought about by Science. People would not have been so well-dressed in the absence of the textile industry. Now the market is flooded with enormous variety of clothes whether they are required for summer of sever winter. Today, India is producing clothes to such an extent that it can export to other countries after meeting its own demands. Electricity has changed the entire scenario of society. With the help of electricity, man can do any number of activities and has progressed in every part of the industry and daily life. At nighttime, the place can be changed to daylight conditions. Even matches are played under flood lights.
The most wonderful invention of science is man-made satellites. The wildest dream of human beings has come true. Man has landed on the moon. The force of gravity has got no meaning for man and he has conquered it. The society is getting information of all other planets and research is being made continuously to know more and more about other planets. Weather conditions are being predicted with the help of pictures taken by these satellites.
The change brought in by Science is clearly visible in our ways of living. The agrarian society is fast changing into an industrialized and highly advanced culture. Big industrial towns are coming up into existence with their own multiple infrastructure. The world has contracted and time and distance have no relevance left. Fast and sophisticated means of communication and transport have brought the different societies closer. In short, the advancement of science has made our social life prosperous.

Is Science a Blessing or a Curse

The gifts of science are indisputable and countless. There can be no denying the fact that science has made so much progress that life of a man, society, nation and the world has advanced tremendously. The knowledge gained learn through science and scientific technology speaks volumes about man’s ingenuity and skill. If all this was not achieved by science it would be no wonder that, even today, man might have been the animal as he was in the ages past – i.e. just another animal. It is science that has given us all the amenities of modern living that we can proudly boast of end enjoy.
The drudgery of household work has been reduced to an almost nil by the numerous gifts of science. You have much task to do, and there is a machine to do it for you. In its social aspect, no matter where we want to go, whomsoever we want to meet, the scientist has helped us and we have umpteen scientific modes of traveling to and fro. We want entertainment, the radio and then the television are at our doorstep to do the job, in our drawing rooms or in the bedrooms. If we want to gain knowledge we have other media – books. This is also the result of mechanization of solving problems. When we want to know more about other countries of the world, we have the internet to help us out. So, in a nutshell, we can say that, the twins of science and mechanism have brought us out of the darkness of the woods. Let us understand that, is the subject, and mechanization is the outcome. We can say the two are like two bodies and one soul.
Our lifestyle is now undoubtedly much above and the animal that of man ages back. This journey has taken man centres but, it has been worth it. Now, having studied the gifts of Science to mankind, it will do us some good if we do some introspection and try also to study how, and to what extent we are now misusing our scientific knowledge. As far as science is helping man to make life better it is very good but, does man stop there? He continues his so-called study and research which further leads him on to the destructive capability of science. We are in for making bombs, using nuclear energy for purposes of destruction. Today man has the most destructive weapons ever produced. One bomb can annihilate civilization. In the event of a third world war, there is no doubt that man will perish. It is at this aspect of scientific growth we must put a stop whose gain will it be, if the world is destroyed? I am sure it will benefit none. Yes, none at all. We must understand that we should not pursue the track that leads to annihilation. All the gifts of science must be enjoyed to the full and that can happen only if man survives to taste the fruits of mechanization. Production of destrictive weapons the greatest curse of science to men.
On the home front also it is felt that, too much mechanization, accounts for our inability to work of our own self. We get so used to machines that our bodies get absolutely frozen and become unfit to do any work. Moving about all the time in cars makes our physique. This creeps several diseases. We become basically very lazy.
On the national front, mechanization has led to industrialization which, in turn has given birth to extensive unemployment and capitalism. Machines being devices to save labour, have mercilessly thrown thousand out of employment, and capitalism has led to class struggle, the big capitalists exploiting the poor labourers.
At the lowest and smallest level of life, man has lost his own humaneness as though he himself has become a machine. He has got so enmeshed in the machines that the has lost all contact with his own species who make for his live company. This live company has been sacrificed for the mechanical idiot box. As son as man loses touch with his kin, he is most likely to become a machine whose company he keeps all the while. The human touch which was so special about a family and the society is getting lost as every individual has become more or less a machine.
Besides these mundane and down-to-earth results of scientific growth, there is one very important aspect which has got lost. Science leaves no place to accommodate God or religion. For the scientific and mechanical mind can understand only what he sees or, something that can be explained with some amount of reasoning. God and religion are two things that can have no mathematical formulae to explain. Today’s man cannot understand this so called foolish premise of the existence of any God.
This disbelief in God is leading to further degeneration of the family and the society, the two essential composites of a healthy nation. There does not in today’s context seem to be any force that can convince man of the necessity of being God fearing and thus being good. Man understand only what he can see and these days his vision is too blurred to see the place of God in the scheme of things. This irreligious attitude of man is further bringing down to the lowest ebb, the sensitivity of our very beings.
Thus we see that the blessings of science though innumerable, have a matching number of abuses. The abuses are so great that they even pose the danger of complete annihilation of the human race, both physically and mentally and of course spiritually. Looking at the sum total of the scenario the abuses outnumber the blessings. This is because man is basically destructive by nature and getting too much of scientific know-how will only confirm his doom.
