If I am to understand Bell’s theorem correctly, then I must suppose that if we are running a Stern-Gerlach experiment on entangled pairs of electrons and I measure one with spin up then I can be assured that if you measure its entangled partner its spin will be down against a given magnetic field direction. However, I cannot therefore do any physics or build any device that depends on that outcome if only I make a measurement. What does that even mean?

Pandemic question
After a year of masks and social distancing and lockdowns, the pandemic seems to be raging up over and over again with apparently more and more contagious mutations appearing. Could it be possible that what we’re really seeing is a consequence of a weakening in general of everybody’s immune system due to mask wearing? If we’re not exposed on a continual basis to pathogens our immune system lets down its guard so to speak.
