In 1949, an american engineer, the captain Edward A. Murphy, worked for the Us Air Force on the MX 981 project and had to study the effects of deceleration on Men during a crash. For this experience he had to dispose sixteen sensors on the body of a pilot.  This mission was entrusted to a technician, knowing that each sensor could be applied according to two positions: the good and the bad. The technician installed the sixteen sensors in the bad position. After what Murphy emitted the sentence "If anything can go wrong, it will".  This Law of pessismism  or also called the Law of the buttered toast (because a toat always falls on the buttery side) has become so popular that all around the world, people have created some proverbs, some other Murphy's Law around the same principle.

 

Here are a few of them:

 

          "If everything seems like its going well, you must have neglected something."

"Every solution brings another problem."

"Everything that brings pleasur is illegal, immoral or makes you gain weight."

"The most interesting men and women are already taken, and if they are not taken, there is a hidden reason."

"If it feels too good to be true, it probably is."

"The qualities a women seeks in a men are sually the ones that she can't stand after a few years later."

"Love is the victory of imagination on intelligence."

"Friends come and go, but  we accumulate ennemies."
