Karl Popper
a philosopher
tried to identify the nature of truth
said that a scientific statement must be falsifiable
rejected to the claims of scientists of seeking truth
the opinion of the scientists
many great scientific changes didn't come through falsification
object to his theory of truth
His picture of men of bold ideas
new and daring conjectures
daring if they take a risk of being false
they try first to find not being wrong
copernicus's,Aristarchus's conjecture
was bold as it clashed with all then accepted views
rejected hidden reality behind the appearence
the sun was on the center, but it is false
they didnt predict new observable appearences(un scientifc)
they made minor predictions(scientific)
Kepler
detailed predictions of the apperances
three laws of planetary motion
they approximate to truth but they r not true
Einestein's theory of graviation
led Popper to the philosophy of science
bold,not the truth that decidd the theory
regard his theory as refuted, and it was false
