HarveyH55★★★★★ (5197)	The law is: radiance = SBconstant * emissivity * temperature ^ 4 Still think there is some error in the calculations... How do you calculate the SBconstant for the human? The emissivity? I don't know the math involved for either. Think there is some difference between a solid inanimate body, and a living, breathing one. Which makes one wonder why no one considered that if the human expired, while in the room, would he still be warming from the cool surface? Of course not, and the police could use the ambient temperature of the room, and the internal body temperature to estimate the time of death. I don't know where the 700 watts, or 2000 calories come from either. Both seem kind of high. 70F is considered comfortable for many, little cool for my tastes, but not uncomfortable with it. From frequent experience here in Florida, 98.6 F isn't comfortable at all, might be the humidity that goes with it, here anyway. We don't need to work that hard to maintain internal body temperature. Pretty sure the equations fail, when applied to living things, instead of solid objects.

It's 0.0000000567 But, how do you calculate the SBconstant? It had to be derived from something, or was it just picked randomly? I've never needed this level of math for anything, nor real see much use for it, beyond this discussion, which is why I tend to stay out of it. Being warm blood, means being cold tolerant. We hold onto heat, as well as produce our own. But, all animals produce heat from activity. It's the skin, the layer of fat under it, and how the blood vessels are routed, that hold and regulate temperature for us. Emmissivity for human skin was gathered here. "Infrared images were acquired with a SATIR infrared camera, model S280 " on 40 volunteers and had a range from 0.991 to 0.999. I've only seen a few IR cameras used, so not real familiar. Not something I've had a need to know. It tend to learn things I need to use. Pretty sure though, it's thermal imagery. How would the readings been effected, if some of the volunteers had been more physically active, before the reading? Race or gender? I've only heard of Stefan-Boltzmann here, on this forum, so figure it's real world application is sort of limited. Which leads me to believe, it's not applied to everything for a reason. I work with electronics, as a hobby, and keep up with the technology. I don't read everything about all things though, would have time to actually build anything. But if something catches my interest, or I see some potential for a project, I'll look into it. Stefan-Boltzmann should have come up once or twice, in something. P(out)=σeA*(T1^4) Greek letters are shorthand for a page or two of math (exaggerating), but it's additional calculations. Only familiar with 2 or three of the Greek letters, in relation to electronics, the rest I have no idea. The shorthand, usually tells me it isn't quite as simple as it looks though. I only had a half year of Physics, in high school, over 40 years ago... So, really can't draw on that much, barely an introduction. It was a whole lot more fun and interesting, than Metaphysics in college.

HarveyH55★★★★★ (5197)	The laws of thermodynamics, physic in general, have always proven to be pretty solid, least the ones that apply to the physical world. I avoid the metaphysical, it's mostly just arguing and debate, not so useful or productive. If the laws of physics weren't solid, why no perpetual motion machines, or free energy devices? Thousands of people try, and there have been many clever attempts. Perpetual motion has been an interest of mine, since childhood. Though, it was never the belief that it was ever going to happen. It was more like a magic show. You know that magic isn't real, it's a trick, an illusion, but still entertaining. Think that there is actually some value in a few of these illusions, since they require a high level of efficiency. I seldom look at perpetual motion schemes any more, since it became a highly profitable fraud. The devices being developed, are intended to be misrepresented, and sold. It's not about trying to break the laws of physics, just break the laws in general, and get rich off it

Don't you think it's reasonable there would be one textbook in the world that teaches radiative heat transfer properly? I really never studied enough physics to know. All the light/heat stuff is outside my fields of interest. Most of the heat I've dealt with, is in electronics. I don't generally work with parts that generate a lot of heat, unless driven too hard, or incorrectly. There are some that generally require a heat sink, and don't really require math. I'm pretty sure that if common physics, an the laws of thermodynamics were proven wrong/flawed, it would have been big news. I've only had one textbook for physics, and it was a very long time ago. Could have been before the Stefan Boltzmann Law was invented, or Karl Popper redefined science. Most of my formal education ended in the mid 1980s, Karl Popper died 1994, so was probably taught science wrong, metaphysically speaking... I never look it up, but guessing the Stefan and Boltzmann were also philosophers, as was Karl Popper. Mostly, it seems Stefan Boltzmann Law applies to thermal imaging, and maybe that was the intended use, and it works well. The problem seems to be when it's applied in other ways. Works fine displaying information on a screen, and maybe useful deriving temperatures from an image capture with a camera (likely stretching it a little).

If you are saying that "some" heat flows from cold to hot, just less than that which is flowing from hot to cold, then you are acknowledging that some heat flows from cold to hot, i.e. exactly what Into the Night said. Your response should have been "Yes, that is exactly what I am saying, and here's the simple repeatable experiment that so demonstrates this principle."
