Scientific Progress

Most scientific progress is the result of careful consideration of work that has already been done. The wonderful world which lies before us today has been put up by hardworking men with clear heads and inventive mind, and these who follow them along life’s road will improve on their efforts. It is sometimes necessary to question and even to disbelieve some of the statements made by experts. Action or experiment can often end an argument or achieve a breakthrough.

When men were wondering whether it was possible to reach India by sailing westwards from Europe, and whether there was any land on the other side of the Atlantic Ocean, Christopher Columbus decides to act. He gathered some men, invited them to go on board his three ships, and set out across the dangerous waters of the Atlantic Ocean. He was successful in finding land, but it was not India. The result of his action was that the arguments came to the end.

Any young man who wishes to do research must be courageous enough to question old beliefs and do some original thinking about them. Although we seem to know so much, there are many things we don’t know. Even when we pull an atom to pieces, we do not really know what the pieces are, we often do not reach the reality behind what we discover, and the more we learn, the better we realize our ignorance.
