- - - - - - - - - Truth and learn, it would be a very inefficient system. In honesty are fact, the early civilization progress was slow for needs for this very reason. But our brain is not just any survival. computer, but a self-learning computer. This All values are built up means that, with the given information we can from the increase the useful output by many permutations needs of and combinations. Let us suppose, we have learnt human from our work that the mango tree flowers better society. after a period of drought. If we have this experience, the human brain has the capacity to extrapolate this information to other flowering trees and test the conclusion. This is the basis of scientific research. It is in-built in the human brain to extrapolate and test earlier results. In all activity, we try to anticipate results and then consolidate or modify our "hypothesis' depending on how it stands the test. The major importance of this ability is that the rate of acquisition of new knowledge becomes related to the amount of knowledge already present. This is exactly the situation (as a mathematical equation) that gives exponential increase of knowledge. In common language it means that, like compound interest, the knowledge grows explosively. Thus, keeping up with work activity, the knowledge growth keeps increasing. And therefore we cannot rest and say we have enough mental patterns and we shall keep playing with the same old patterns. This is what we do now in our school education, we keep playing with a small stock of experience. The implication of exponential growth (as against linear growth) is two fold: A: Even if we go slow in the primary school, but make sure the learning is proper, the acquired knowledge will grow fast later. On the other hand, if our learning is not proper at the primary level, it will not give exponential growth and later growth will be slow. So give a firm foundation to the primary school education. « Rural Development Through Education System 105
