All Murphy says is that if you drop a hammer, it will fall and do damage rather than just harmlessly fall or bounce.

Overmod Erik_Mag How does that jibe with Murphy's law of selective gravitation, e.g. a dropped hammer will land where it will do the most damage. That's not Murphy's law; it's a corollary of Finagle's Law (the perversity of the Universe tends to a maximum).

Interesting Wiki discussion involving two forms of heuristic bias:
"According to Richard Dawkins, so-called laws like Murphy's law and Sod's law are nonsense because they require inanimate objects to have desires of their own, or else to react according to one's own desires. Dawkins points out that a certain class of events may occur all the time, but are only noticed when they become a nuisance. He gives as an example aircraft noise interfering with filming. Aircraft are in the sky all the time, but are only taken note of when they cause a problem. This is a form of confirmation bias whereby the investigator seeks out evidence to confirm his already formed ideas, but does not look for evidence that contradicts them.[20]
Similarly, David Hand, emeritus professor of mathematics and senior research investigator at Imperial College London, points out that the law of truly large numbers should lead one to expect the kind of events predicted by Murphy's law to occur occasionally. Selection bias will ensure that those ones are remembered and the many times Murphy's law was not true are forgotten.[21]"
charlie hebdotwo forms of heuristic bias:
IMHO this is getting too complicated. Google simply says: Murphy's Law ("If anything can go wrong, it will") was born at Edwards Air Force Base in 1949 at North Base. It was named after Capt. Edward A. Murphy, an engineer working on Air Force Project MX981, (a project) designed to see how much sudden deceleration a person can stand in a crash.Aug 5, 2014
Simple: If anything can go wrong it will.
Of course a variety of the original have be created.
Remember the "KISS" rule. My wife in her elementary classroom changed the
last word to "sweetie" endmrw0317231830
And we can't forget:
Murphy was an optimist.
One modification: Everything takes longer and cost more than you think.
And one I've never heard anyone else mention but seems to apply to me: If there's a 50/50 chance of getting something right, somehow I'll get it wrong about 90% of the time.
I'm not sure this is qualifies as a Law, but if it is, we might call it Mickey's Law:
"The early bird gets the worm,
but it's the second mouse that gets the cheese."
A couple of favorites from the EE field:
When writing specifications, Murphy's Law supersedes Ohm's.
Oscillators won't, amplifiers will
If I remember correctly, Murphy was speaking about an engineer, and the original quote is something like "if anyone can get it wrong, he can".
One of my favorites was
* After the last of 32 hold-down screws has been removed from an access cover, it will be discovered that the wrong access cover has been removed.
* After the last of 32 hold-down screws has been torqued for an access cover, it will be discovered that the gasket has been omitted.
Overmod... * After the last of 32 hold-down screws has been torqued for an access cover, it will be discovered that the gasket has been omitted.
Remember - those 32 hold down screws had to be torqued in three steps to come to spec before the missing gasket was discovered.

To make this story more UNBELIVABLE this was a government project.
My mother had a 1st cousin, USS Meyer, named after him. He rose to be an admiral. He was in charge of building the first of this class ship. He had a philosophy of build sub parts and testing BEFORE attachment on the ship. Guess what: The first ship he built was.......UNDERBUDGET and AHEAD of SCHEDULE.
On that same note: Can we trust Bill Stephens reporting? Last paper issue, Trains pg 6, interview w/CP CEO. Wow what a read! Anyone find fault w/this man's philosophy? I emphasize there are good numbers there to back him up. Anybody with downside to this way of operating a RR? As Paul Harvey said, "What's the rest of the story"?endmrw0318321638

As Larry is a "ham", surely more than once he has soldered center conductor on the male fitting....only to discover he had NOT sliden the threaded ring on the cable before installing what goes inside it endmrw0318231646

This is getting way off subject, but it is too tempting to ignore. 2 Law of Thermo.....simply everthing tends to dissorder. I'm exchanging perverisity = disorder. I submit, to keep this on subject.

Yep. I was putting new ends on a couple of electrical cords the other day and even though I wasn't soldering the connections, I still checked twice to make sure the upper part of the connector was where it needed to be...

I got a lot of soldering practice rebuilding a molex connector or twenty after doing that.
I wonder if the OP could possibly edit the title of this thread so that, say, five years from now if someone were to search for the Springfield, Ohio derailment of 2023 it would come up toward the top of the search results.
I wouldn't necessarily remember "bites the dust" in that context.
