Quote from Robert A.Heinlein on science

 There are but two ways of forming an opinion in science.One is the scientific method;the other the scholastic.One can judge from experiment,or one can blindly accept authority..To the scientific mind,experimental proof is all important and theory is merely a convenience in description,to be junked when it no longer fits.To the academic mind,authority is everything and facts are junked when they do not fit theory laid down by authority.-Robert a.Heinlein,LIFE LINE.
