Particle Physics and Sudoku

Particle Physics is in some ways like an infinitely difficult Sudoku.  An improper clue or a mistake anywhere in the progression may not show up until the final square. Then the entire effort crumbles. Everything that appeared to work then must be questioned.  At that point one must go back to the beginning and start anew since it seems impossible to backtrack.  To backtrack in theoretical or experimental physics is highly improbable, as each step along the way is a child of some great mind.  Some new thinker must say, ”Here is what you missed.”
