Acceptance: a theory is said to be accepted if it is taken as the best available description of its object // object can be physical (ex:apple, tree), social (ex: group of people, social institution), formal (ie. number) Use: a theory is said to be used it is it taken as an adequate tool for practical application. Pursuit: a theory is said to be pursued if it is considered worthy for further development- worthy of further elaboration. 1)classical physics (newtonian physics) no longer believe this is the more accurate theory to describe reality but its still relevant and easier to use. 2)m theory pursued because this might be the next big thing in physics. 1)ptolemeic astronomy: coper(cid:374)i(cid:272)us" astronomy (useful in calculating the distance of planets)
