Document Summary
Self-correcting: new evidence/observations new interpretations. Four steps of the scientific method: observe (where the evidence comes in, hypothesize (a reasonable explanation for the observation, predict (what are the other applications of the hypothesis?, test predictions (look for new evidence to support/refute predictions) Hypotheses and predictions must be able to be proven wrong: otherwise, the explanation is not a scientific hypothesis. While hypotheses can be very strongly supported, they can never be proven 100: but they can be disproven 100% Scientific theory is an explanation that has been tested repeatedly and has yet to be disproven the best theories incorporate lots of well-supported hypotheses. Theories are as (cid:272)lose to (cid:862)truth(cid:863) as (cid:449)e (cid:272)a(cid:374) get to.
