Nick Spark fell down a rabbit hole tracking down the origins of Murphy’s Law, the ubiquitous phrase that says “If it can go wrong, it will go wrong”. On this episode of Decoder Ring, we follow Nick on his journey while taking a few detours of our own to find out how Murphy’s Law was [maybe] born out of the rocket sled experiments of the dawning jet age. We talk to Nick, hear some of the recordings he collected during his own research, plus talk to researchers who are skeptical of Nick’s hypothesis, all to try and find out how an obscure engineering aphorism spread to world-conquering philosophical observation.
