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.
Science is a systematic and logical approach to discovering how things in the universe work. Scientists use the scientific method to make observations, form hypotheses and gather evidence in an experiment aimed at supporting or contradicting a theory.
