Confused Thinking

AI Thread Summary

The discussion centers on the concept of blackbodies and their temperature characteristics. It questions whether a blackbody maintains a constant temperature or if there is a temperature gradient based on proximity to a heat source. The consensus suggests that the temperature uniformity depends on the specific modeling scenario and the assumption of thermal equilibrium. Understanding these factors is crucial for accurate thermal analysis. The clarity on blackbody temperature behavior is essential for various scientific applications.

I've been thinking about blackbodies, and have become confused with regards to their temperature. Is the temperature constant throughout in a blackbody, or is there a temperature gradient dependant on which side is closest to the source of heat? Would it matter?

That just depends on what you are modeling, and whether you can assume equilibrium.

Thread 'The Physics of unloading sand from a barge'

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...

Thread 'Is space stretching or is new space being created?'

Do we even know? My understanding of dark energy is that particles come into existence, exert and outward force, then vanish. My problem with that is how, of course, then how does dark energy know to push everything in the same direction? The pressure exerted would be in all directions, even if the space was moving so why isn't stuff pushed all over the sky? Thanks - rev
