What actually defines science?
Is it the inclusion of facts and figures? Hypotheses and theories? The ability to think and analyse something that no-one else before has questioned?
Generally speaking, the majority of scientific discovery builds upon what has gone before. For example, Mendeleev didn't just coin the periodic table from thin air he worked from all the other basic predecessor tables, and then reworked the places for the elements to sit to match their characteristic properties.
It seems that science isn't only about 'discovery' but it is also about looking at something through fresh eyes and in a way that makes you stop and question a theory and dive a little deeper.
