No. tmiddles wrote: Also you are the only one calling an approximate number "randU". No, I am not. tmiddles wrote: I looked that up and it was a random number generator tool famous for being bad at being random. Guess you forgot that too. I explained what randU was. I'll go over it again just because I feel like it. Pay attention this time. This comes from random number mathematics. There are three types of random numbers: randR, randN, and randU. randR is the type of random number you get from dice. It has no memory. The number can repeat any number of times or never even come up at all. randN is the tpe of random number you get from cards. It has a memory. Once a card is pulled, you cannot pull it again, until a reset event occurs (such as a shuffle). randU is the 'predictable' random number. This is the kind of number that comes out of someone's head, or the algorithm for such a number. Any time you just make up a number out of your head, that's a randU. tmiddles wrote: So calling things an "randU" number is just confusing. Nope. It's now been explained for you AGAIN. Pay attention. tmiddles wrote: If you're saying it's random use the world random. What is 'random'? What makes a number 'random'? Because it looks 'random'? Just how 'random' is it? Imagine a person rolling a single die on a craps table. You could, theoretically calculate the position of the die when it's picked up, the size of his hand, how sweaty it is, how fast and how high he throws it, where it contacts the felt and at what speed, where it snags on the felt and begins to roll, where off the back wall it bounces, and where it lands, and what face will be showing when it stops. This calculation will require incorporating many large values and variables, all to generate a number from one to six. In other words, you need to calculate something of very high resolution to get a very low resolution number. So, what is 'random' and how 'random' is it? It is a number generated by a difference of resolutions. That difference can be expressed as a ratio, and directly indicates just how 'random' our random number is. This works for randR and randN, but what about randU? People also make up numbers. If you consider all the possible synapses that can fire to create some number, it IS random, but those synapses are generating that number for a particular purpose (usually to embellish an argument). Thus, this random number is 'predictable'. It is what computer scientists call the 'psuedo-random' number. It occurs anytime you think of a number to use. It occurs anytime you use words like 'all', 'everyone', 'none', 'most', 'few', 'some'; or if you use numbers to indicate such concepts. tmiddles wrote: In this case random is not at all the best way to describe a number which is an average or a common value within a range. You are not using an average. There is no data. You are just picking a number out of your own mind (or someone else is picking a number out of their own mind and you're just copying it). The concept of 'average' is often just a randU as well, since the dataset is not specified and no average is run. Remember, the dataset MUST be closed to generate an average. If you try to use an open dataset 'average', the 'average' itself is a randU. To attempt to use a randU as data is the argument from randU fallacy. Random numbers are not data. Now pay attention to this. Write it down. Copy this note into your files. I will not repeat it again for you. This is a branch of mathematics that is rarely discussed. For some reason they don't teach it much in schools either, not even computer science programs. The use of random numbers in any other branch or Domain of mathematics renders that branch incapable of the power of prediction, normally inherent in a closed system like mathematics.

tmiddles★★★★★ (3979)	Into the Night wrote: There is no such thing as 'net flow'. Heat only flows in one direction. Radiance does not only flow in one direction. If that's your theory it is exotic and unsubstantiated. You both offer nothing other than a circular definition of your own creation. I have proven it wrong with the first post of this topic. Neither of you have even offered an explanation as to how we aren't all freezing to death right now. Go ahead by the way, no one can stop you. To be clear on the crux of the issue: Your revolutionary claim that radiance from a cooler object, when it strikes a hotter object, is not absorbed, is disproven by my example. By the example of all of us right now sitting in rooms cooler than we are, radiating over 700 watts, and yet not freezing to death. That you both actually know I'm right is clear from the lack of any attempt at an explanation of your own.

Applying the Stefan-Boltzmann equation to values known to be in the range of what we find among people is a fallacy? How is that? Also are you able to explain anything. Anything at all. Pick one thing related to thermodynamics that's actually occurring in the world around us and give us your explanation with calculations to back it up.

RE: Emissivity study data31-08-2019 00:03
tmiddles★★★★★ (3979)	So! Temp ~ 91F/33C/306K, Surface area ~ 1.5m2 of skin, Emissivity ~ 0.97 The mean surface temperature of the skin is approximately Temp ~ 91F/33C/306K, but there are variation all of which are heavily studied. One exmple: facts_about_skin The surface area is determined using the Mosteller calculation Here is the raw data, method of determination, for emissivity of skin measurements from 40 subjects here: https://www.spiedigitallibrary.org/journals/journal-of-biomedical-optics/volume-14/issue-02/024006/Novel-approach-to-assess-the-emissivity-of-the-human-skin/10.1117/1.3086612.full?SSO=1 Subject Emissivity Subject Emissivity Subject Emissivity Subject Emissivity 1 0.996 11 0.998 21 0.994 31 0.998 2 0.994 12 0.996 22 0.998 32 0.999 3 0.998 13 0.991 23 0.997 33 0.997 4 0.999 14 0.998 24 0.997 34 0.999 5 0.998 15 0.992 25 0.995 35 0.995 6 0.998 16 0.992 26 0.999 36 0.992 7 0.996 17 0.997 27 0.990 37 0.998 8 0.996 18 0.995 28 0.993 38 0.998 9 0.992 19 0.998 29 0.999 39 0.994 10 0.998 20 0.997 30 0.997 40 0.995 That's 40 subjects with emissivity all over 0.95 Now your exotic claim about a cooler objects radiance not being absorbed by a warmer body is debunked by my example based on the loss from radiance be too great for food energy alone to replace. (as in a person in a room would freeze to death if they couldn't absorb the radiance of the room). So there is a range for all three of the above parameters. Temp: 77-99F Area: 1-2M Emissivity: 0.992-0.998 All three correlate with the temp loss so the lower they are, the lower the temp loss. So let's pick a very very ill person, who's whole body is as cold as someones feet at 77F, the skin area of a small child at 1.0m2, and the low end of emissivity at 0.992. But they are still eating a robust 2000 calorie diet. Stefan-Boltzmann equation:___P(out)=σeA(T1^4) (5.67×10−8J/s⋅m2⋅K4)(0.97)(1.50m2)298K^4=-723W 0.00000005670.9921.07886150416=443.56 Watts So that's 443 Watts out from radiance as per Stefan-Boltzmann for our small child sized, deaths door they are so cold, adult diet eating test subject.

GasGuzzler ★★★★★ (2938)	I don't know anything about your equation, but I do know that the answer to your "freezing to death" in a 70 degree room has everything to do with conduction. Skin will conduct very little heat to air at 70 degrees, but sit in a tank of 70 degree water for an hour and you're going to find yourself in trouble. It's about the coupling for conduction. Air is a poor coupling. Beer in the freezer will get cold. Beer in ice water will get cold FAST. This is repeatable and I have done it SO many times. Edited on 31-08-2019 08:31

That it would make up for the energy lost through radiance? Bringing conduction into it is not a problem. According to the theory that ITN and IBdaMann have on the 2nd LTD there is no way that a person who is warmer than the room they can gain any energy from either radiance or conduction. Basically you can only be cooled off by the room. So to be clear: If a cooler body (includes the walls and air of the room) cannot contribute any energy to a warmer body (your body) you can only lose energy through conduction. That's why I ignored it in this post. It only makes the problem of accounting for the lost energy from radiance worse. According to ITN and IBdaMann the air, which is cooler than you, cannot "give you" any energy, only take it. So if you believe in the Stefan-Boltzman law then you lose that energy. If you believe in ITN and IBdaMann's version of the 2nd LTD then you could not calculate a way to maintain body temperature outside of a 14,000 calorie diet.

tmiddles★★★★★ (3979)	GasGuzzler wrote: If you reduce the current in a river does some of the water flow upstream? Can you reduce radiance? Would less cold air cause someone's radiance to be reduced? Would colder air increase their radiance? No. What does happen is simple. We absorb the radiance from the room. We only notice the difference between our radiance and the radiance of the room (just like with conduction). We are not magically immune from absorbing it. tmiddles wrote:Does it balance at 70F ? YES You don't sweat or shiver in a 70F / 22C room. Thermal energy balances with radiant emission -723 watts and radiant absorption +624 watts and your metabolism digesting food +100 watts. It's just not like one flowing river. It's two rivers that are able to pass through each other. Not even ITN and IBdaMann suggest that radiance from a cooler body is prevented from moving from the cooler body all the way to the hotter body, which would be your "up stream", they just have this bazaar idea it's somehow rejected when it gets there.

Let's take an example of a man in a cool room. By conduction, the cool air causes the man's skin to approach the room temperature, thus reducing the man's radiance. Also, the adjustment in human skin as it cools also happens to have the effect of reducing its emissivity and its thermal coefficient which reduces its radiance and conduction. tmiddles wrote: We absorb the radiance from the room.

Would less cold air cause someone's radiance to be reduced? Would colder air increase their radiance? No. What does happen is simple. We absorb the radiance from the room. We only notice the difference between our radiance and the radiance of the room (just like with conduction). We are not magically immune from absorbing it. It's not magick. No molecule will absorb a photon that has less energy than the molecule already has. tmiddles wrote: tmiddles wrote:Does it balance at 70F ? YES You don't sweat or shiver in a 70F / 22C room. Thermal energy balances with radiant emission -723 watts and radiant absorption +624 watts and your metabolism digesting food +100 watts. It's just not like one flowing river. It's two rivers that are able to pass through each other. Not even ITN and IBdaMann suggest that radiance from a cooler body is prevented from moving from the cooler body all the way to the hotter body, which would be your "up stream", they just have this bazaar idea it's somehow rejected when it gets there. Rivers don't pass through each other. You really ARE reaching now. You are close to a thought experiment that has much to do with the 2nd law of thermodynamics. Say you have a water wheel. Now hook the shaft of this wheel to another identical wheel, and use that wheel to pump the water back up to power the first one. Can you power the wheels forever this way?

By conduction, the cool air causes the man's skin to approach the room temperature, thus reducing the man's radiance. Would you be willing to do a calculation? What temperature would you say human skin is at in a 70F room and based on what data? (I have backed up the 91F temp). A persons temperature will reach 70F in a room of course upon their death. IBdaMann wrote: Also, the adjustment in human skin as it cools also happens to have the effect of reducing its emissivity and its thermal coefficient which reduces its radiance and conduction. What change would that be? It it's normally 0.98 in a climate controlled room what would it change to? Just making stuff up? IBdaMann wrote: tmiddles wrote: We absorb the radiance from the room. Warmizombies are forever claiming that physics applies to everything... Why don't you just do the calculation properly IBD? Enlighten us. Edited on 31-08-2019 23:35

No. Um you realize that's an insane theory right? If I have a book at 70F, it radiates. If I have a box at 70F it radiates. If I put the book inside the box, according to you, the entire radiance of the book and the radiance of the box would be emitted and then become permanently homless inside the box, building and building, unable to be abosrbed by anything.

Anything colder becomes warmer until equilibrium. Anything warmer becomes colder until equilibrium. You completely dodged the question. Again. Into the Night wrote: tmiddles wrote: IBdaMann wrote:Try again... ... That's all of it! Note the lack of ANYTHING resembling a response or rebuttal. Cherry picking fallacy. You did not show all of his responses. And once again the truly disrespectfully long quoting and replying from ITN, the false claim that something was said, but the refusal to quote that. Into the Night wrote: Now, what, in your opinion, has greater radiance than the whole Earth? The sun. Get on with it. And you guys are insane, so stop trying to play teacher. Into the Night wrote: tmiddles wrote: According to the theory that ITN and IBdaMann have on the 2nd LTD there is no way that a person who is warmer than the room they can gain any energy from either radiance or conduction. Basically you can only be cooled off by the room. So you must eat. How much? Calculate it. I did. tmiddles wrote:Since 2000 calories, 7/8 of a pizza, gives you 100 watts of heat you'll need 14,000 calories, and eat 6 large pizzas a day, working it all of, just to maintain body temperature! Into the Night wrote: tmiddles wrote: If you believe in ITN and IBdaMann's version of the 2nd LTD Thanks for the credit, but neither of us wrote that law. Oh no you did. Your version of a 2nd LTD where radiance is magically unabsorbable by hotter objects cannot be found anywhere else. Into the Night wrote: tmiddles wrote:t's just not like one flowing river.

Gasguzzler said it was like a river I said it wasn't. Radiance CAN pass through radiance. Edited on 31-08-2019 23:38

You are again forgetting something very large, very hot, and very significant. It's up in the sky. Do the calculation ITN I dare you. Sun warms planet and the building/room from the outside. The room is still cooler than the person inside. The person radiates over 700 watts. And ________? Edited on 31-08-2019 23:46
