The real purpose of the scientific method is to make sure nature hasn’t misled you into thinking you know something you actually don’t know.

For every fact there is an infinity of hypotheses.

The TV scientist who mutters sadly, "The experiment is a failure; we have failed to achieve what we had hoped for," is suffering mainly from a bad script writer. An experiment is never a failure solely because it fails to achieve predicted results. An experiment is a failure only when it also fails adequately to test the hypothesis in question, when the data it produces don't prove anything one way or another.

But slight mistakes accumulate, and grow to gross errors if unchecked.

Nature engenders the science of painting.

The aim of science is not to open the door to infinite wisdom, but to set a limit to infinite error.
