"Politics is the art of possible." Similarly, "Science is the art of soluble." Explain this beautiful aphorism on the nature and practice of science

It is said that word ‘impossible’ is missing in the dictionary of a politician. Politics is, therefore, treated as an art of making every impossible thing possible for a politician. Similarly, there is hardly any scientific problem which cannot be solved by a scientific approach. Science is therefore treated as an art of getting solutions for those problems also which appear to have no solution because even most complex phenomena of nature have their explanations in terms of a few basic laws of physics.
