What kind of brush: sable whetted with vinegar, or copper whetted with H2SO4, or ...

Your skull as a mop, whetted with the stupidity of John Larkin.

Both exhibiting their resultant heat addition to the world... nil, and the emissivity of your skull mop... zero.

You are both cold, retarded bastards... the weakest links in any society.

One more for the list, Michael.

You're an idiot. The pussy already has it, and you are the one months behind the curve. As usual.

No, that's another retread.

  • That is yet another surface preperation that would change emissitivity...
  • Now we are into Global Warming...

  • Global Cooling???

Does he have a real name?

John

It was 1 degreeF up here this morning. Bummer, I was hoping for zero.

It's up to 19 now. 8 feet of fresh snow. Maybe I'll go skiing.

John

"AlwaysWrong" is a real as he gets.

73F, now, and rather sunny. Tomorrow it's supposed to be colder (60F) and rainy. :-(

Does it ever really snow in San Francisco ?

He doesn't even have a real head. :(

73F overnight, around 82F for a high today. Another day without needing heat or A/C. :)

My heat came on one morning, Nov. 5 IIRC, just as I was going to work. THe month started out pretty nasty but has been pretty nice since. The AC hasn't been on since early October. We'll have a couple of months with electric bills under $100.

What part of NIL do you not understand?

The last two were $80 and some change.

Human skin has an emissivity close to 1. Hair probably has high emissivity, but it's a good thermal insulator, so an IR measurement of a hair-colored skull won't mean much.

Interestingly, water is high, something like 0.98 at thermal wavelengths. So is ice.

The medical IR thermomeneters that they stick in your ear have an ideal situation: a long tunnel with e=0.98, practically a perfect black body.

You're a total retard.
