Universal Law for Naive Engineers

Engineering & Science Humor - RF CafeThese engineering and science tech-centric jokes, song parodies, anecdotes and assorted humor have been collected from friends and websites across the Internet. I check back occasionally for new fodder, but it seems all the old content is reappearing all over (like this is). The humor is light-hearted and clean and sometimes slightly assaultive to the easily-offended, so you are forewarned. It is all workplace-safe.

Humor #1, #2, #3

The Recommended Practices Committee of the International Society of Philosophical Engineers

Law #1: In any calculation, any error which can creep in will do so.

Law #2: Any error in any calculation will be in the direction of most harm.

Law #3: In any formula, constants (especially those obtained from engineering handbooks) are

              to be treated as variables.

Law #4: The best approximation of service conditions in the laboratory will not begin to meet those

              conditions encountered in actual service.

Law #5: The most vital dimension on any plan drawing stands the most chance of being omitted.

Law #6: If only one bid can be secured on any project, the price will be unreasonable.

Law #7: If a test installation functions perfectly, all subsequent production units will malfunction.

Law #8: All delivery promises must be multiplied by a factor of 2.0.

Law #9: Major changes in construction will always be requested after fabrication is nearly complete.

Law #10: Parts that positively cannot be assembled in improper order will be.

Law #11: Interchangeable parts won't.

Law #12: Manufacturer's specifications of performance should be multiplied by a factor of 0.5.

Law #13: Salespeople's claims for performance should be multiplied by a factor of 0.25.

Law #14: Installation and Operating Instructions shipped with the device will be promptly discarded

                by the Receiving Department.

Law #15: Any device requiring service or adjustment will be the least accessible.

Law #16: Service conditions as given on specifications will be exceeded.

Law #17: If more than one person is responsible for a miscalculation, no one will be at fault.

Law #18: Identical units which test in an identical fashion will not behave in an identical fashion

                in the field.

Law #19: If, in engineering practice, a safety factor is sent through the service experience at an

                ultimate value, an ingenious idiot will promptly calculate a method to exceed said

                safety factor.

Law #20: Warranty and guarantee clauses are voided by payment of the invoice.

Law #21: The rule for engineers: "Change the data to fit the curve."
