e.g.: devoted scientists: Kepler, Einstein

never satisfied with own results

its results: regarded as approximations

can be falsifiable

takes the risk of clashing with reality

consists of: bold (daring, unacceptable) conjecture

Science

based on truthfulness

looks for confirmation not falsification

immunized against criticism

observation, hypothesis, testing

Non-science or Pseudo-science
