Murphy's Laws

Maybe someone has heard of Murphy's Law, but few know exactly what they are. Today I will try to answer this question.

For the uninitiated, these laws, so famous in the U.S. to be present in some dictionaries are written humorous phrases whose intent is to mock all the negativity that the newspaper describing it offers so overly pessimistic. In general, those images and scenes described with phrases didactic frustrating and can be summarized in the First Axiom of Murphy

"If something can go wrong, it will"

Despite the ironic meaning assigned to them in the imagination policy, the laws have a deeper meaning, known to anyone involved or interested in security: even if a certain event has a very low probability of occurring, this can always happen. In practice the laws are the exaggeration of the reasons why doing prevention.

If you search for the author of all these laws, you will find the name of Arthur Bloch, the person who has collected and written in a book. In this book he cites the original as a writer Edward A. Murphy Jr.
This figure nothing is certain. It seems that American aviation was an engineer in 1949 and was working on an experiment where you had to apply 16 sensors on a man for the strength of the human body to acceleration. Each sensor could be applied in two different ways on the body and because they were never mounted in the right way uttered a phrase that passed into history:

"If there are two or more ways to do one thing and one of them can lead to a catastrophe, someone will do just this, "

The phrase became famous because the subject test, Major John Paul Stapp, repeated it during a press conference a few days later.
