Hypothesis Testing 
     vs. Theory
           “Don’t confuse “hypothesis” and “theory.”
           The former is a possible explanation; the
           latter, the correct one. The establishment
           of theory is the very purpose of science.”

     Hypothesis Testing Finds Truth
             “One finds the truth by making a 
             hypothesis and comparing the truth to 
             the hypothesis.”
