Hello,
According to the Academic Press Dictionary of Science & Technology science defined as "1. the systematic observation of natural events and conditions in order to discover facts about them and to formulate laws and principles based on these facts. 2. the organized body of knowledge that is derived from such observations and that can be verified or tested by further investigation. 3. any specific branch of this general body of knowledge, such as biology, physics, geology, or astronomy"
it seems to be like investigation ,discovering and known to unknown (research) always play a important part of science.
