Have you ever received a phone call the minute you stepped outside
your door? Has the bus you were waiting for ever appeared from
behind a parked truck the instant you light up a cigarette? Certain
astute individuals have noticed that such events are not the
exception but, rather, the rule. Men like Murphy, Peter and
Parkinson have made it their life work to ferret out the operating
principles - the laws that govern the frustrating lives that we
mortals live. Here is a small sampling of these laws.
Murphy's Law
If anything can go wrong, it will.
If anything can't go wrong, it will go wrong.
If anything can't go wrong on its own, someone will make it go wrong.
O'Tool's Commentary on Murphy's Law
Murphy was an optimist.
Murphy's Law for Engineers:
The more innocuous a design change appears, the further will its influence
extend.
Any error that can creep in, will. It will be in the direction that will do
most damage to the calculation.
A transister protected by a fast-acting fuse will protect the fuse by
blowing first.
