Claimed OU circuit of Rosemary Ainslie

See my posting above it has zero to do with Aaron's setup.

I saw your post.  Poynt's point was not valid.  Discussed by Harvey at some length.  And you will note that Poynt did not argue it.  The 'base line' ambient moves more slowly than measured ambient.  And 'apparent' cool to the touch - is not indicative of actual temperature. 


In any event, it's the phenomenon that intrigues me.  But it's apparently accommodated in mainstream physics.  Just never heard of it before.

Rosemary:

I didn't read Harvey's discussion.  From my searching what I found was not too clear and I had no energy so I gave up.

I think that the gist of it is this:  The measured temperature of an object in a room is determined by several factors.  The ambient air temperature will put thermal energy into the object because of the air molecules crashing into it and transferring their energy.  There is light energy and infrared energy shining on the object and some is absorbed and some is reflected off.  Then the object is radiating away the energy imparted into it at various wavelengths, I assume mostly infrared wavelengths.  Everything falls into balance where (air molecule + light input energy = radiated energy due to emissivity).  Therefore objects that radiate away more energy than other objects and/or absorb less imparted energy from external radiation have a lower baseline temperature.  I am really out of my realm here but I think that is the essence of it.  Thereofore the physical makeup of objects, their colour and surface texture and the materials they are made of will determine their baseline temperature.  The baseline temperature is normally lower than the ambient air temperature.  It's something like that.

Golly MH  A rare admission of doubt?  You're definitely growing on me.  I won't add to your summation here because I'm also not an expert.  But I'm inclined to believe that Harvey is.  So, unless I hear to the contrary I'll go with his explanation.

Don't mistake a non-response as an admission of error. There are other reasons for not responding. To be kind and not waste my time, I'd rather leave it at that.
