Origins of Science:
We have seen that the primitive human beings acquired different kinds of knowledge from the use of implements and tools, from cooking on fire. from hunting animals and gathering fruits or seeds of plants for food. All this knowledge blended into one common pool and together with the rituals and myths of society formed their culture. What we now have to find is the origin of science in the womb of this culture. We can see developments in the following three broad areas, which had implications for science : a) Rational Mechanics By making and using tools, man was transforming nature according to his deliberate will. This laid the basis for mechanics of rigid bodies, motion and properties of materials. The handling of bow and arrow, the javelin or the boomerang are some example. Again, in the use of lever, it was possible to know before hand what would happen to one end when the other end was pressed. In the use of such devices, the useful results of interaction with nature could be 'seen' or 'felt'. Thus, understanding and confidence developed. At least, in one sphere, human beings were realising how things worked.
