The origin of Murphy's law
Edward A. Murphy is a captain engineer at Edwards Air Force Base in the United States.
1949, he and his boss, Major stapp, participated in the deceleration overweight experiment of MX98 1 rocket conducted by the US Air Force. The purpose of this experiment is to determine the tolerance limit of human beings to acceleration.
One of the experimental projects is to hang the 16 rocket accelerometer above the subject. At that time, there were two ways to fix the accelerometer on the bracket, but incredibly, someone methodically installed all the 16 accelerometers in the wrong position.
So Murphy made this famous conclusion that if there are many ways to do a job, and one of them will lead to an accident, then someone will do it in this way.
