Related to Certain Peculiar Laws of Inexactitude Perversity
and Whimsey in Scientific Endeavor
MURPHY'S LAW - If anything can go wrong, it will.
SKINNER'S CONSTANT - That quantity which, when multiplied by, divided by, added to, or subtracted from the answer you get, gives you the answer you should have gotten.
(This is also known as Flannegan's Finangling Factor)
HORNER'S FIVE-THUMB - Experience varies directly with equipment ruined.
CAHN'S AXIOM - When all else fails, read the instructions.
THE SPARE PARTS PRINCIPLE - The accessibility, during recovery of small parts which fall from the work bench, varies directly with the size of the part - and inversely with its importance to the completion of the work underway.
GUMPERSON'S LAW - The probability of a given event occurring is inversely proportional to its desirability.
THE ORDERING PRINCIPLE - Those supplies necessary for yesterday's experiment must be ordered no later than tomorrow noon.
THE TRANSCRIPTION SQUARE LAW - The number of errors made is equal to the sum of the "squares" employed.
CHISHOLM'S LAW OF HUMAN - Anytime that things appear to be going better you have overlooked something.
RIDDLE'S CONSTANT - There are coexisting elements in frustration phenomena which separate expected results from achieved results.
THEORY OF INTERNATIONAL INTERACTION - In any calculation, any error which can creep in, will.
RULE OF ACCURACY - When working toward the solution of a problem, it always helps if you know the answer.
ADVANCED'S COROLLARY - Provide, of course, that you know there
is a problem.
