Why do we Learn Science?

We learn science to gain knowledge about the world around us. If we know more about what we are dealing about in life, we can deal with these things better than if we were uninformed. For example a scientist can figure out what an unknown substance is by observing it. For him to know if this substance is safe or not he must have good knowledge of how substances react under certain cicumstances. This also applies to all fields of science, doctors must know the human body to do their job properly engineers also must know their field of science. without knowledge of science we couldn't make advanncements because we wouldn't know about our world, how it would react, and what can be done with that reaction.
