There have been many cases that adopted proof by contradiction for creative researchers to prove their
theory and to explore the weak points of the existing theories. However, there has rarely been trials to
represent the problem solving process with the proof by contradiction as a diagram. This research explained
how to represent creative research’s contradiction resolution process applied with the proof by contradiction
as the Butterfly diagram. Archimedes solved the golden crown problem with the proof by contradiction in
a situation that was difficult to prove if the golden crown was pure or not. Galileo Galilei proved that
Aristotle’s law of falling bodies was wrong from the thought experiment. He proved that the bodies of
different weight fell with the same speed by proof by contradiction. Einstein proved that the velocity
addition law was contradicted with the law of light speed constancy. From the proof, he discovered an
error in Newtonian mechanics. This research represented the application process with the Butterfly diagram
for solving contradiction resolution in scientific history. In addition, this research proposed the valid
argument by a truth table
