Most people in our society take science as something strange and crazy, which are the works of Newton, Einstein and few others persons known as scientists. The works of so-called scientists led to the invention of rockets and bombs which are threats to human civilization. Also science contradicts the age-old belief on the existence of god, hell and heaven. Wrong notions about science and technological advancement are the main causes of our ignorance and backwardness. As a consequence, we are suffering from poverty, shortage of food, diseases and lack of medical facilities, lack of drinking water, shortage of electricity and so many other benefits, which people in the developed world enjoy.
We have to dispel our mistaken notion of science and technological advancement if we want to get rid of most of our problems related to underdevelopment. The history and survival of humankind is a story of the growth of science. The desire to survive led early human to learn to hunt. In that process, they devised tools. The discovery of agriculture led to the process of growing food through irrigation, farming and cropping. The curiosity to communicate with others led to the invention of language and the art of communication which continued to grow further in the form of written language, printing and wireless communication. This was a revolution continuing still today in the development and spread of internet. The urge to go to different parts of the earth led to the growth of transportation. Now the movement of humans is not confined only on the surface of earth bu to the top of the mountain, deep inside the sea and as far as the planet mars. People are thinking about inter-space travel. There are many other fronts of developments which are the direct consequence of the development of science and technology. Notably among them is the advancement of medical science and medical technology.
Science is not something which concerns only scientists. We wake up in the morning and see that the sun rises or appears in the east. In the evening the sun sets or disappears in the west. We are all familiar with the changing seasons. Some parts of the earth have heavy rain whereas other parts have snow and very hot deserts. The nature of plants and animals, even the colour of human beings in different parts of the earth differs. We need water to drink .We don’t drink water from all sources. Water from some source may upset our stomachs. We have diseases like malaria, typhoid, and hepatitis and nowadays AIDS. Insects crawl on grounds, birds fly and animals and human beings walk on ground. Many animals live on grass and green plants but human beings need cooked food.
During winter nights, if you look at the sky, you see tiny twinkling dots known as stars. If you look more closely, you find several differences among the stars. Stars appear only in nights. Moon also appears only in nights but not at all nights. Sometimes our sun and full moon are covered by strange black shadows known as eclipse.
We all are aware of the phenomena described in the last two paragraphs. We can cite many other natural phenomena which happen in our daily life. During illness we take pills and capsules of medicine and get cured. Sometimes we do take medicine in the form of injection but how many of us and how often do we ask ourselves why and how different natural phenomena happen? Why sun always rises in the east and sets in the west? Why do we get monsoon more or less in the same time each year? Why we need medicine when we are ill and how medicines cure us? How different varieties of breads, cheese and butter which appear in our breakfast table are prepared? Very recently we have started showing concern for our environment. What has happened to our environment and how? Why the rapid industrialization has dismantled some of the natural resources?
Many of us take all things and happenings around us without any wonder. But there are persons who wonder about these things. They are curious to learn more about their surroundings and the happenings with the question “Why?” and “How?” They wonder why the sun shines and what cloud is like. They wonder why a book falls to the ground when we drop it. They wonder at the stars, planets, and the moon.They wonder as how star is born, how many stars are there, why there are patches in the full moon, how vast is the universe and so many other questions. Most discoveries came out because someone wondered.
But discoveries are not made by wondering alone. You may wonder and ask questions as “How?” and “Why?”But who answers theses questions? You observe, listen, feel and learn to satisfy your curiosity. By doing so you make some idea about something or some happening. In other words, you come out with some explanation. If this explanation alone satisfies you, then you are not a scientist. The difference between a scientist and others lies here. A scientist likes to verify his/her understanding or explanation of something by experiment. In many cases we might have made a guess but we could not be sure. So we do the experiment and it can give us a true answer. Experiment and discovery go hand in hand.
A curious mind asks questions and comes across new riddles and puzzles. You may be bored and give up solving them. Others may come out with some valid explanations of these puzzles. But how do we know whether these explanations are correct? Those who continue to know the correct answers to these riddles and puzzles either by explanations or by experiments are scientists. Scientists have to correct their understanding or explanations and experiments again and again until they bring out the truth. Sometimes scientists discover the answers to their problems in a very short time. More often, they must experiment patiently and carefully for years before they find out what they want to know. They may do one experiment a thousand times, or a thousand different experiments just to discover one fact.
Now, if you are also intrigued to think like a scientist or think that you have a potential to be a scientist then think about the question, “Assume that the earth does not rotate around its axis. How will this affect us? Assume next that the earth does not go around the sun, what will happen?”
