Politicians make anything and everything possible to win votes. Science is a systematized study of observation. Scientist and researchers study these observations and then work out certain laws from them. There is a multitude of natural phenomena taking place in this universe and all of them can be explained in terms of some basic laws.
For e.g. F = mg is true for you and me and also for a star. Thus, in science we see that various phenomena are related, they are soluble and can be explained with similar or the same law. This goes on to justify that science is the art of the soluble just as politics is the art of the possible.
