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.
What is key in the description of the scientific method just given is the predictive power (the ability to get more out of the theory than you put in; see Barrow, 1991) of the hypothesis or theory, as tested by experiment. It is often said in science that theories can never be proved, only disproved.
