I have a random physics question:
A solid sphere, in ordinary atmosphere, with a magical heating element at one pole and a magical refrigeration element at the other. If the sphere itself is stationary and at room temperature; one pole is super-cooled while the opposite pole is super-heated. (Edit: Assume the axis connecting the poles is horizontal.)
What effect does this have on air-flow around the sphere? Does it move? If so, in which direction?

Okay, so I have a "self-healing" router that ostensibly reboots itself once a week to "allow channel switching" and to "promote network health", and given that this seems to NOT mess up my internet access in one of several ways every tuesday morning only MOST of the time, it has been causing me stress absurdly out of proportion with the actual danger (of being without internet access/my ONLY link to the outside world, for a short time).
So, my question is, what the HECK does "channel switching" or "promoting network health" even mean, and is it actually important enough that I shouldn't just flat out disable my router's "self-healing" feature?
