I take it for granted that you have not read the texts, arguments and lengty argumentations about why science is what it is today. That is, what is
scientific method, why it is used, why we do not trust other methods that much and so on and so on.. I may be wrong, so I will also add some general
facts about science.
Lets start with this basic and general knowledge which is known by nearly every scientist on earth.
Science has a goal, and that goal is omnisciency. Basically this means knowledge about every mechanism and effect (solutions to problems are the stuff
engineers do, that's why I do not include a solution in context of purpose of science).
Scientists also know that science is an evolving thing, usually going forwards but sometimes we have been taken steps back as well. Because science is
an evolving thing, and because we do not know everything yet, it becomes obvious that science always goes closer and closer to truth. We may not have
a perfect knowledge about some effect yet, but our science always evolves to be more exact, more precies. I'll give you examples.
Newton first realized Three laws of motion. Those laws can be used to tell an exact spot a baseball hits when it is hit with particular force and
angle. The law is accurate enough so that we usually use it when we have to know a spot some object end up in. It is not _exactly_ accurate, but when
error is in micrometers, it really doesn't matter in everyday applications.
That means we use laws that are wrong, but which can still be used to accurately tell a lot of things when our treshold is large enough. Science is
right in that these Laws can be used in hundreds of differents fields of knowledge, manufacturing and development.
Then came Einstein, and created a theory that can explain these things even more accurately. His laws are great and are known in genral by most.
However, his laws are not needed in product development, manufacturing or everyday applications. We do not need an accuracy that good. Complexity of
his theories rule out most engineers as users of his theories anyway. Yes, we can measure orbits of planets quite accurately with his laws, but even
those calculations appear to be in error. But it doesn't matter, usually. If we know orbit on Mars, and that knowledge has an error of one inch, we
can safely say that his laws are extremely useful because such a small error only matters in timescales of hundreds of billions of years, which is
well above lifetime of the habitable universe.
Does this ring a bell? Science develops accuracy, and accuracy is nearly always better and better, yet previous laws known to be in error are almost
never useless, and can be used to explain a billion things, because error in accuracy is usually small enough to be ignored.
I always ask certain questions from people who think science hasn't developed into a state where we can be certain that some things really are true
and know.
One of those questions is this: You have a TV, which works because its function is solely based on physical laws. Those laws are known, and engineers
have developed your TV by _deducing_ how to do it _from_ physical laws.
Now, do you realize that TV would not work if logical deduction is somehow flawed or that those physical laws are somehow flawed? They aren't and a
working appratus based on those laws proves that. They may not be perfectly accurate yet, but accurate enough to actually create our current modern
civilizaion. Get that?
So, in a nutshell:
Science creates methods, of functions if you will, and engineers then use this knowledge and deduce solutions with logic (basically equals to math in
our context). If logic fails or if a usefullness of a law of nature fails, the appratus that they created does not work.
