Is it not like saying: Basically Special Relativity is a theory about observations that occur in a common-sense classical world - its not quite as weird as some popularisations will give the impression it is eg length contraction is not required, particles do not time dilate - all the really...

I just want to know whether the metal case heating up is caused by convection or ir radiation.. what is usually the case.. that's all.

notice the black metal case is like a blackbody (because it's painted black) and the chip is black too.. so the question is.. would there be significant transfer of heat from the chip to the metal case by plain ir radiation? I think it should, isn't it. because I can't see how conduction by air...

atyy, bill.. I think there is a mistake inside the paper above.. specifically in section 1.2.3 where: "However, note that even though 2 = 3, their physical interpretation is not quite the same. System 2 is in a definite deterministic physical state, whereas system 3 is part of a composite...

or let's just use a very simple setup... just two metals let's say one inch apart.. when one is heated 70 degree celsius.. is there significant radiative heat transfer from one metal to the other? i thought IR radiative heat transfer is only important for the sun-earth heat transfer bec the sun...

Here's an actual setup I tried. The square metal case is 1 inch high and 1.6 inch in the 4 of its sides. There is a small camera processor (13mm x 13mm) at bottom with temperature of 70 degree Celsius.. I opened the top metal cover to test if the temperature just rise straight up to outside from...

Let's say you have a small metal case that is 3 inches by 3 inches versus 2 inches by 2 inches. Inside at center is a heat generating source (let's say a small processor chip). How efficient is the transfer of heat from the processor to the air... and from air to metal between the 2 different...
