The future of a nation depends on the scientific temper of its new generation. The new generation is going to shoulder the responsibilities of the old very soon. The young should know that the universe follows the rules of nature. We have to discover these rules. Such discoveries give us great power. Man has made great advances in knowledge, science, technology, and thought. Other animals could not progress even a step further. This is because man doubts, mam enquires, man experiments, and man proves. Other animals do nothing but follow their elders. To know the truth is the basis of scientific temper. Doubt leads to an investigation. Faith leads us to fanaticism.
