Science humor
The science community usually takes their work very seriously and for good reason. At any moment an accident could occur and life-threatening chemicals could be spilled or released into the air. If you work with new machinery, malfunctions could happen which can jeopardize the entire experiment and cut funding.
So it’s no wonder why this scientist who specializes in physics felt ridiculous when he forgot the word for ‘photon’ and used ‘shiny crumb’ instead. We feel for you man, all those years of education and you slipped up once, resulting in your peers never letting you forget it. Proof that reputations can be destroyed in seconds.
