La loi de Murphy

Qui ne connaît la loi de l’emmerdement maximal? Son inventeur présumé, Edward Murphy, ne s’attendait sans doute pas à ce que son énoncé serve de titre à un film frais et léger, comme le cinéma français parvient parfois à en produire. Un vrai régal.

Personnellement, j’ai toujours pensé qu’il y avait plusieurs lois de Murphy. Peut-être une mauvaise lecture du ‘s de la possession. Je me souviens, cependant, avoir croisé un texte composé de plusieurs lois scotché sur la porte d’un chercheur, à l’ENST ou à l’INRIA, un peu semblable à celui-ci:

                        MURPHY'S LAWS

THE PRIME AXIOM: In any field of scientific endeavor, anything that
                     can go wrong, will.

 2.  If the possibility exists of several things going wrong, the one that
      will go wrong is the one that will do the most damage.
 3.  Everything will go wrong at one time.
      3.1 That time is always when you least expect it.
 4.  If nothing can go wrong, something will.
 5.  Nothing is as easy as it looks.
 6.  Everything takes longer than you think.
 7.  Left to themselves, things always go from bad to worse.
 8.  Nature always sides with the hidden flaw.
 9.  Given the most inappropriate time for something to go wrong, that's
      when it will occur.
 10.  Mother Nature is a bitch.
      10.1 The universe is not indifferent to intelligence, it is actively
            hostile to it.
 11.  If everything seems to be going well, you have obviously overlooked
      something.
 12.  If in any problem you find yourself doing an immense amount of work,
      the answer can be obtained by simple inspection.
 13.  Never make anything simple and efficient when a way can be found to
      make it complex and wonderful.
 14.  If it doesn't fit, use a bigger hammer.
 15.  In an instrument or device characterized by a number of plus-or-minus
      errors, the total error will be the sum of all the errors adding in
      the same direction.
 16.  In any given calculation, the fault will never be placed if more than
      one person is involved.
      16.1 In any given discovery, the credit will never be properly placed
            if more than one person is involved.
 17.  All warranty and guarantee clauses become invalid upon payment of the
      final invoice.
 18.  Murphy's Law: "If there are two or more ways to do something, and one
      of those ways can result in a catastrophe, then someone will do it."
