Validate precise scale with less precise scale
Is it possible to validate the measurements of a precise scale with a scale wich is less precise? Let’s say I have a scale wich can display values down to 1g and another scale which can display the...
View ArticleHow is the total spin of a particle actually measured?
Say I have a fermion whose total spin I do not know. I then use a stern gerlach setup to measure $S_z$. If I find +1/2, I could say that the total spin is $1/2$. But it could also be the eigenket...
