Why my baggage needs to go thru X-ray to go out of airport in Panama City? Is it OK to create a third prong ground from a cold water pipe, for a 2-wire circuit? Is staying in the first job for a long time (>2 yrs) a bad thing?
Proposition is a statement about observable phenomena(concepts) that may be judged to be true or false.When a proposition is so formulated for empirical testing ,we call it a hypothesis..As a declarative statement about the relationship between two or more variables, a hypothesis is of tentative and conjectural nature.
My formal (but open to improvement) definition of 'science': A science is a method, a set of rules using fact and logic, for evidence gathering and testing truth claims in a given field of inquiry, rules which are publicly usable (i.e., neutrally applied to all participants), and which can reasonably be said to lead to the truth of that particular area.
