Science is not a mindset or field. It is an act of accomplishing understanding. If there is something mankind can reason about, we can also do science-y stuff with it.
"What about a poll among 33 leading thinkers at a conference in Austria in 2011. This group of physicists, mathematicians and philosophers was given 16 multiple-choice questions about the meaning of the theory, and their answers displayed little consensus."
"One of the most telling questions in the Austrian poll was whether there will still be conferences about the meaning of quantum theory in 50 years time. Forty-eight percent said “probably yes”, only 15% said “probably no”. Twelve percent said “I’ll organize one no matter what”, but that’s academics for you."
From a BBC article by Philip Ball.
When we observe this, we come up with explanations as to how it happened, describe it using mathematics or chemical symbols or whatever is appropriate. In this way, science is done.
There are still a lot of mysteries out there today. Scientists are working on explaining them.
Suppose we observe that when A happens, B occurs. This does not imply that A causes B. In fact, we can never confirm that A causes B, regardless of how closely we measure the reaction. 'Preposterous!' I hear you say on the other end of the intertubes.. but alas, it is true. Beyond the realm of reality and hubris we might observe that in fact X causes Y, and that A is simply an observable effect of X. Similarly, B is just an effect of Y. If you really want to explode that mind, think about how broadly this concept can be applied.
