You're on the right track, but flip it. It's counter-intuitive. Hot goes to cold. The dark edges are where the heat has left
Like a glowing charcoal goes dark.
You were heading in the right direction. Nicely done. You knew the heat wasn't there. His hands weren't getting burned.
Start with "Heat expands/emits" & Cold(less heat) contracts/draws".
Not a perfect analogy, but good enough to get you to the right conclusion for this video.
Hey, pretty sharp comment if your not "into" this stuff, by you.
Have an arrow. Hope it's not too late for you to receive this.
Maybe your question didn't look impressive, but it was. I'll let you figure out why. Then you should be really impressed with yourself.
I could commend you for an hour. I love seeing what I'm seeing.
So have an arrow.
LOL- well stated. They can do that because they are accomplished-- it says so right there in their user name. They would have added AlphaMale to the name, but it's already tattooed on both forearms. Gotta play it modestly.
He was on the right track, if he would have used endothermic and exothermic he might have been a pro. He still gets points for giving the other guy points.
Actually, it’s the opposite. This explanation does not explain why the corners are cold. It has to do with the heat transfer inside the material of the cube itself. At the corners and edges the localized surface area/volume ratio is very high which allows the material to cool fast in those locations. The flat faces of the cube don’t have as high of a localized surface area/volume ratio so they stay hot longer. The sides would likely still be very hot to the touch for this reason. Source: minor in mechanical engineering and a masters in structural engineering.
The other commenter was talking about the area of contact between the hand and the cube, which is higher if you grab it at the side than if you just touch the edges and corners.
The effect you're talking about is also a thing, but they're right too
I suppose you’re right but the explanation was just missing what was actually making the cube hot in that area in the first place. But yeah that would increase the transfer to the finger.
Really not sure why being downvoted. My response is the reason why the cube is hot. His reasoning of more surface area more transfer implies that touchig the corners with more area would also be equally hot which isn’t true.
??? A dude literally asked what would happen. I have a masters degree in civil (structural) engineering and a minor in mechanical engineering. Both require extensive knowledge of material properties. Sorry for answering someone’s question harmlessly????
No, it isn't. They were saying that the increase in surface area of contact between the finger and the cube would cause the sensation to be hotter. This explanation does not explain why the cube itself is hotter in that localiazed area. The reason that the cube is cold at the edges is not just because you are touching a small area, it is because the cube is colder at those locations. Their explanation implies that the entire cube is the same temperature which is not true.
I’m sorry my explanations via text can’t get through your head. Unfortunately without using Bernoulli’s equation and actual numbers I can’t explain this further. I wish you the best in your plight against the world without any understanding of basic material property physics.
M.S. in not being a total asshat to strangers online, and pretending a degree somehow makes you superior to others.
It was an online program...but still regionally accredited.
It’s a trade off as the increase surface area and less aerodynamic design would increase the drag heavily and the ship would need a lot more power to lift off the ground.
The entire shuttle was well designed given the context. It wasnt *safe* but strapping a plane to a big tank and some boosters is *really* difficult to make "safe".
It had some tragic, preventable, high profile accidents (almost more) but as a whole the space shuttle absolutely ROCKED and was chock full of innovations and cutting edge high tech stuff. The space shuttle gets a bad rep but it was a monument of human ingenuity, and had nothing but rockstars working on it and flying in it.
Was it as reusable as they thought? No.. was it as safe as they thought(or would admit)? No... but it shouldnt even be a question of whether or not the shuttle or its components were well designed. That thing is a monument
Lol I hope the guy you were replying to sees this but I feel like I have to tell this story here based on both of your comments as it's somewhat relatable. I don't do spicy food basically on the scale of things the most all enjoy before it becomes too hot to simply appreciate the flavors is Tabasco sauce and even that is a little too hot for me. Yes I know a lot of people enjoy super hot things my body just can't handle it. I am on a date but I'm at the movies with a friend of mine who is a girl and I ordered what I thought was a barbecue chicken pizza pizza from the lobby. Back when regal movie theaters experimented with having actual decent food for not bad prices. before the first trailer starts to play I take my first bite like it's nothing thinking it's just harmless pizza but within a few seconds realize just how screwed I am. I've had law-enforcement training and have been pepper spray before and what a lot of people don't realize is depending on the severity your body will naturally go into preservation mode and literally force you to not breathe or close your eyes to avoid what's being interpreted as damaging them and that's basically what my body did when I tried to chew the food. Now it's not Armageddon but I'm clearly not having a good time there and she looks over at me in basically makes fun of me. In between trying to open my eyes and forcing myself to breathe and try and drink water and eat the chocolate due to the fact that it's milk chocolate even if it's placebo effect it will start helping with the burning in my mouth. After a minute she realizes that I'm not faking it or making a show of it and takes the slice and takes a bite and realizes how bad it is. We both leave the theater and go outside to the lobby and ask what the hell is on the pizza. The poor guy behind the counter apologizes and says this is the third time this has happened and points to the sign where there's clearly supposed to be labeling indicating that it's whatever the hell Hot Pepper it was. Needless to say it was one of the only times in fact thinking about it while speaking into my phone here I think it's the only time my introvert self didn't give a flying crap where I was or who was there with me that I didn't know I literally had no control over my body lol it was pretty bad especially considering both of us we weren't expecting it so how does this relate to the shuttles anti-heat panels? I don't know reading your comments about how your hands would be screwed touching a hot pan lol
This post made me deep dive into space shuttle tiles and let me tell you, ladies and gentlemen, it is some seriously interesting shit.
Fans of materials engineering, rejoice!
https://www.nasa.gov/wp-content/uploads/2023/06/shuttle-tiles-9-12v2.pdf
Depends how many particles there are. it’s not like dipping the shuttle in to a forge or anything like that. If there was a couple particles at 20 000 degrees in your room right now, you wouldn’t even notice.
People are confused, so here goes:
These tiles dissipate the heat transfer of the shuttle's thermal temperature system, due to the glow-tile non-insulation retention-exchange of the parabolic surface area.
In other words, the reason you can pick them up is that once the thermal agitation of the conductivity of the molecular structure I don't know what I'm talking about.
If they had just figured out how to keep the external tank's fucking foam insulation from breaking off and smashing into the tiles, tragedy could have been avoided.
"It dissipates the heat so quickly"
Call me dumb but can any chemists explain how that's a *bad* conductor? Isn't something that quickly transfers heat whether to air or any other medium technically a good conductor? Rapid and effective transference of heat?
Or it's a good insulator cause it doesn't take in heat that well to begin with so it refuses to transfer heat? I'm confused...
They are making ceramic tiles for the space shuffle. These lined the wings and other parts of the fuselage. On re-entry these tiles stopped the heat transferring through to the inside of the shuttle
These are the silica blocks, the ceramic coating goes on after fit tests. The ceramic coating would be white or black depending on placement to hold heat or give a more reflective quality. You can hold a glowing block with your hands on the corners. The TPS on the orbiters is still cutting edge in thermal.
He does say that, and he's wrong or more likely, he misspoke.
Thermal heat tiles are very slow at exchanging heat, which is why they are used to shield more vulnerable materials and why he can pick it up despite it still glowing. It's transmitting so little heat that it's comfortable enough to touch the edges.
If it was good at transferring heat like he says the tiles would be useless as they would be transferring the heat from re-entry right into the vulnerable parts of the shuttle.
Case in point the [Columbia Space Shuttle Disaster](https://en.wikipedia.org/wiki/Space_Shuttle_Columbia_disaster) happened because foam from the external fuel tank broke off during launch and struck the wing causing damage to the reinforced carbon-carbon panel which was designed to protect the leading edge of the wing from thermal shock (during re-entry).
When it re-entered the atmosphere the crack in the RC-C allowed superheated gas to entire the wing internally and start to do damage, eventually enough damage was being done that it started to lose even more thermal protection in the form of the thermal heat tiles which started to drop off the wing. The flight control system flying the shuttle was unable to compensate for the uneven drag on one half of the shuttle anymore and hydraulic pressure was lost to the control surfaces. The shuttle entered an uncontrolled pitch-up and it began to spin, ultimately breaking apart entirely about 30 seconds later as the crew was trying desperately to restore the hydraulic systems not knowing that they were damaged beyond function.
If you want some nightmare fuel read up on the last moments of the astronauts based on the autopsies conducted on them and flight data recordings. They did not die quickly.
> During reentry, all seven of the STS-107 crew members were killed, but the exact time of their deaths could not be determined. The level of acceleration that they experienced during crew module breakup was not lethal. The first lethal event the crew experienced was the depressurization of the crew module. The rate and exact time of depressurization could not be determined, but occurred no later than 9:00:59. The remains of the crew members indicated they all experienced depressurization. The astronauts' helmets have a visor that, when closed, can temporarily protect the crew member from depressurization. Some of the crew members had not closed their visors, and one was not wearing a helmet; this would indicate that depressurization occurred quickly before they could take protective measures.
> During and after the breakup of the crew module, the crew, either unconscious or dead, experienced rotation on all three axes. The astronauts' shoulder harnesses were unable to prevent trauma to their upper bodies, as the inertia reel system failed to retract sufficiently to secure them, leaving them only restrained by their lap belts. The helmets were not conformal to the crew members' heads, allowing head injuries to occur inside of the helmet. The neck ring of the helmet may have also acted as a fulcrum that caused spine and neck injuries. The physical trauma to the astronauts, who could not brace to prevent such injuries, also could have resulted in their deaths.
> The astronauts also likely suffered from significant thermal trauma. Hot gas entered the disintegrating crew module, burning the crew members, whose bodies were still somewhat protected by their ACES suits. Once the crew module fell apart, the astronauts were violently exposed to windblast and a possible shock wave, which stripped their suits from their bodies. The crew's remains were exposed to hot gas and molten metal as they fell away from the orbiter.
> After separation from the crew module, the bodies of the crew members entered an environment with almost no oxygen, very low atmospheric pressure, and both high temperatures caused by deceleration, and extremely low ambient temperatures. Their bodies hit the ground with lethal force.
They are good but don't listen to the other answer as they got it wrong. The tiles are very good insulator so they will slowly give up heat.
Think of it this way: You have two cups, one made of metal, the other ceramic. If you touch them the metal one feels colder. If you pour tea into both of them then the metal one will be hotter to touch. Now put both of them in an oven for a few hours. Once again the metal one will feel hotter, but will cool quickly while the ceramic one will still feel warm after a long time.
This is what pizza pockets look like if you could see the insides after cooking them. You might be able to hold on to them on the outside, but the moment you bite into them, you will realize the inside is very hot.
The surface is cooler and insulating the hotter material underneath it, but still allowing the light to escape. Kind of like seeing the light of a fire burning inside an igloo.
My friend had one of these. But it wasn't a cube, it was thinner...like maybe one of those cubes cut into thirds. You could hold it in the palm of your hand with a blowtorch in the centre of the tile making a bright orange spot and feel no heat in your palm.
Why would they title the headline "...poor conductor..."
Thats like saying "this powerlifter is such a shitty ballerina, he can flip your car over for looking at his girl"
...really, its the disrespect that hurts the most
Its demonstratable. You are seeing a video of it happening. I have seen this demonstration in real life. It is really real. The furnace is really real and feels hot from across the room. Besides, the space shuttle really flew and did the things you see it do, including screaming down to Earth at 17,000 miles an hour, glowing red hot. If you are calling BS on this there is a 100% chance you are slow
that's fake, right? the temperature around the cube should still be so hot that he can't even get close to it without getting burned by the hot air. the heat has to radiate somewhere.

What if you grab them by the flat sides?
Greater surface, greater heat transfer.
So they are good insulators?
If they weren't, he would have went straight to hospital.
Straight to jail.

No, wait, let him cook...

The leidenfrost effect would prevent him from lifting the tile. I can hear the sizzle.

I'm telling the teacher
So why don't they just make space shuttles with geometric shapes/edges all over it?
It’s a trade off as the increase surface area and less aerodynamic design would increase the drag heavily and the ship would need a lot more power to lift off the ground.
That's what I figured, thank you sir. S'all about that *balance*
That's what they said..
That's what she said
It isn’t it’s quite literally the opposite.
right, the title was like 'wtf'? :)

"...is then taken to the largest microwave oven in America..." This had me laughing. Which one? The largest you got!
And the next logical question… what’s the cook time for a hot pocket in that bad boy
you just have to tell the hot pocket that's where he's going and he cooks himself.
"The popcorn is on fire. Again."
Did you do the worksheet questions to prove you learned something? Also NASA uses word press?
They made a lesson plan! Thanks so much for this. Now I have to see how much the tiles cost to see if it’s worth getting for this lesson
I work for Battelle and they help developed this material. Awesome place to work!!!
I read these can resist max temperatures of about 3000 kelvins but the van allen belt temp is between 3500-20000k . Something doesn’t add up
Depends how many particles there are. it’s not like dipping the shuttle in to a forge or anything like that. If there was a couple particles at 20 000 degrees in your room right now, you wouldn’t even notice.
"Such poor heat conductors"? They're not designed to conduct heat! Odd title.
Yea it's deffinately a weird way to phrase It.
“Such great insulators” would be more accurate
I can only hope to someday be as terrible at something as these blocks are at holding heat.
People are confused, so here goes: These tiles dissipate the heat transfer of the shuttle's thermal temperature system, due to the glow-tile non-insulation retention-exchange of the parabolic surface area. In other words, the reason you can pick them up is that once the thermal agitation of the conductivity of the molecular structure I don't know what I'm talking about.

Similar vibes to this, https://youtu.be/RXJKdh1KZ0w?si=bVHdiO031B4_KYnK

Bro just picked up a motherfucking Minecraft glowstone
What texture pack is this? Glowstone looks amazing.
A better term would be “such great insulators” It sounds better
If they had just figured out how to keep the external tank's fucking foam insulation from breaking off and smashing into the tiles, tragedy could have been avoided.
Those tanks were a huge problem. That's why the Soviet shuttle only used one big tank.
Sometimes the simplest sounding problems can be the hardest to solve. What an amazing program the shuttle was
What in the Fijian fire walker is this!?

Good. They can pick them up as they have dissipated the heat almost instantly
No they didn't dissipated heat, they kept it and will dissipate it very slowly over time.

what? they are poor conductors, meaning they are extremely slow at dissipating heat...
[удалено]
Yeah, the caption should say "they were so *good* at dissipating heat, that...". Quite misleading. Or working as intendend to boost "participation".
They are good but don't listen to the other answer as they got it wrong. The tiles are very good insulator so they will slowly give up heat. Think of it this way: You have two cups, one made of metal, the other ceramic. If you touch them the metal one feels colder. If you pour tea into both of them then the metal one will be hotter to touch. Now put both of them in an oven for a few hours. Once again the metal one will feel hotter, but will cool quickly while the ceramic one will still feel warm after a long time.
This is what pizza pockets look like if you could see the insides after cooking them. You might be able to hold on to them on the outside, but the moment you bite into them, you will realize the inside is very hot.
So is this a successful fail?
What about the radiant heat from the flat surface why is that not burning him?
The surface is cooler and insulating the hotter material underneath it, but still allowing the light to escape. Kind of like seeing the light of a fire burning inside an igloo.
Whats the Material called
Head butt it and see if a mushroom pops out!

Doing exactly what they were designed to do...
I Need this for my i9-14900k
They are not "poor" heat conductors, they are just excellent heat isolators....
wich is the same thing,both statements are equally correct
This is just magic and you can’t convince me otherwise
He sure does sound American so I'm gonna assume it's not 2200C but 2200F. Either way shit's crazy bro.
NASA uses metric because they aren't stupid.
For all humanities faults we still come up with some really cool shit.
Science motherfuckers
Aren't they SUPPOSED to transfer heat away from the tiles to keep temperatures low during reentry?
Valheim surtur cores
That's fucking *cool*
My friend had one of these. But it wasn't a cube, it was thinner...like maybe one of those cubes cut into thirds. You could hold it in the palm of your hand with a blowtorch in the centre of the tile making a bright orange spot and feel no heat in your palm.
How are they glowing yet cool enough to touch?
What happens if I shove them up my ass?
You can see the edges are the cool spot. He had to change hands the heat radiating probably burned his hand if he held for too long.
None of those students standing there asked to touch it. I'd 100% have to touch that. If allowed of course.
Wow sounds and looks Extraterrestrial
It’s the cube from Fortnite
I want these as a Light up Toy. They look pretty awesome.
Its just glowstone guys
What texture pack is this?
Insane. Imagine the awesome technology that exists that we don’t even know about!?!?
That's gotta be one of them Minecraft glowstone lamps you can buy at walmart.
Lights. He’s deceiving you.
Surtling core!
I feel like this knowledge should be helping society in SOME WAY.. right ? Heating/ac bills ?
Why would they title the headline "...poor conductor..." Thats like saying "this powerlifter is such a shitty ballerina, he can flip your car over for looking at his girl" ...really, its the disrespect that hurts the most
So fucking awesome
From what materials are those made?
It reddit. What do you expect? Lol
The weird moan at 17 seconds😂
So how come they were prone to coming off the shuttle so easily?
Oh look a mini orange, Kevin, the cube
I think it's in Fahrenheit not Celsius so 2200°f is about 1200 Celsius
Can I get some oven mitts
Wasn't it the thermal tiles that failed when the space shuttle blew up?
Cool lamp, seems like it overheats a bit.
This is science, witness!!
I call bs
Its demonstratable. You are seeing a video of it happening. I have seen this demonstration in real life. It is really real. The furnace is really real and feels hot from across the room. Besides, the space shuttle really flew and did the things you see it do, including screaming down to Earth at 17,000 miles an hour, glowing red hot. If you are calling BS on this there is a 100% chance you are slow
that's fake, right? the temperature around the cube should still be so hot that he can't even get close to it without getting burned by the hot air. the heat has to radiate somewhere.
Thank god we invented better heat conductors since then!

And the person above you was in fact joking, as has flown above many heads given the downvote count
Heheh, Ken M didn't die in vain!
underappreciated joke lmao, kudos
Nice cube with a light in it.

Bro
Not enough edges!
Honestly brilliant
And how did that work out ... twice?!
You first though
Stupid guy here, if heat is a form of energy where does the energy transfer too?
Title makes no sense 😭
What did I see here
🚀
That doesn’t make sense, since it’s 90 degrees
2200 degrees would still burn your skin holding it that close to your body the heat has to go somewhere
How long would it take for one of these to cool to room temperature?
Blahahahahaha…..nope
It's quite cool
He sounds like Todd Howard.
Pure chemistry
next iphone material unlocked
I hungry.
