@TheDoctorDoodle 11 лет назад

Awesome video. In my doctors office, I have a very hard time convincing some parents that they can not "tell the temperature" of their child by feeling the child's forehead with their hand. What we feel when we touch the forehead is actually how much heat it is giving off, which has more to do with the amount of vasodilation (dilation of blood vessels) than the true temperature of the child. I've been thinking about doing a doctor doodle on this, but you did a awesome job.

Can you please do a video about the effects of freezing time like in the movies?? It would be really cool to see the effects on gravity and light. I think it would be super awesome and I really want to know what else would happen.

@timothymclean 8 лет назад

"Freezing time" is such an aphysical concept that the answer relies entirely on how the writer decides to violate the laws of physics to make the plot work.

@blxxd_ 8 лет назад

well TECHNICALLY, due to how "time" is mainly a perception of decay/regrowth of everything surrounding us, and caused by gravity, it wouldn't be possible to "freeze" it, or at least as people expect you to. you COULD "freeze" a local area (such as a planet) by increasing the gravity or it's speed, as both of those factor to the progression of it. now, while it would INCREMENTALLY change a lot of physics, we can entertain the idea for a moment, and say most things stay the same. for us, the progression wouldn't change. however, to the rest of the universe, the earth COULD get close to stopping in time, however its gravitational pull would have to be greater than most black holes, if not all. the same would work for speed, it would be more effective if you could make a rail around the earth that compensated for thermal expansion, and depressurized it to about 0.001 an atmosphere, using magnetic thrust to achieve very fast speeds, time around you would seem to speed up, but you would technically be "frozen" in time, or what will actually be happening, slowed. now, the reason this isn't possible is for OBVIOUS reasons (excuse my caps, people tend to not read stuff well and don't do any research) with the gravity one, the planet would collapse in on itself and become a black hole, it would likely pull itself closer to the most influential source of gravity near it (the sun) and consume it, but if not, due to size, it would evaporate. as for the speed, the gravitational force exerted on you would kill you, if not cause serious health problems, that would also likely lead to death. but, it's still possible.

@timothymclean 8 лет назад

Bleedoutkid _ Gravity can _slow_ time, even to the point where it _looks_ stopped, but it can never be technically 100% stopped.

@blxxd_ 8 лет назад

it's not pseudo science, it does work. gravity slows time. speed slows time. you could get enough of both to "freeze" time, or since you're apparently stupid, that means at most get 99.9% of complete time stop. relatively speaking, of course, to you things would feel normal, to the rest of the universe you would be completely frozen in time until you somehow ended either of the things. can we do it with current technology? yes, but only to very small SMALL particles, and it only keeps them alive a tad longer than normal. can we eventually do it to humans? well of course, how else will we travel across space to find a planet that we can live on before ours dies? we have a good bit of time left, so as long as we don't go extinct from idiots with their wars, idiots like you overpopulating the people who can make it happen, or our atmosphere giving up, and in that time we can easily have it made, perfected, and in use. will you see it in use? nope, you, I, and most people in these comments will be completely decomposed by the time they get it started. don't chock things you don't understand up to being pseudo science. go study all of relativity and come back to me. if people can't use science that we have to make predictions of how we can use or advance it, then we will never learn anything new.

@revolution0357 8 лет назад

Well I can answer that for you. Nothing would work. If time froze, then everything will stop moving, thus becoming a solid. So even if you could freeze time but leave yourself unfrozen, the now solid air would suffocate you. In lay mans terms, it would be a pretty bad weekend for you.

Why are some atoms a better insulator than others? Like a piece of iron is a worse insulator than fabric, so what makes them so different?

@mtr1x851 4 года назад

Zachary Schreiner Because for any substance to be a good conductor, it needs to have proprieties that makes it spread particule jigling easily. Metals do own this attribute. For example in a nail like any other metal in solid form, the atoms are bound such as they are quite compact and their peripheral electrons mobile enough so that energy is propagated more or less efficiently.

@Muscleduck 11 лет назад

@freedom_aint_free 11 лет назад

What we feel aren't the T (temperature) but the dQ/dt (thermal flux, e.g: Joules per second). The example of the water is more complicate: as the water are one of the substance with the higher (molar) Heat capacity, his dQ = Cp * dT is far more higher then the hot air in the oven and besides that, the vapor in contact with the hands, condensates, and our hands gains further heat by receiving the heat of phase change: from vapor to liquid.

@chargerdave2046 10 лет назад

@mutanttipossu 10 лет назад

Maybe because you expect the coffee to be warm and the beer to be cold so your perception of temperature of the liquid gets messed up?

@chargerdave2046 10 лет назад

They should be the same temp. But i think your onto it. Maybe because we expect coffee to be hot and yada yada

@marlerism 10 лет назад

the carbonation might also be a factor. If the beer was sealed, it'll still be carbonated. To me at least, room-temp carbonated beverages always feel a little bit warmer than un-carbonated. The alcohol content might also be a factor.

@Baby1961-i5e 10 лет назад

But these guys left out a major part of physics. There is really no such thing as cold. Instead there is just the absence of heat. Like if there was an area of space that was at the true absolute zero, meaning no observer, no radiation of any kind, just complete emptiness (reminder; such an area in space is highly theoretical), since nothing is there, there is nothing to "giggle" and zero heat is the state of such a place. But as soon as ray of light, or an observer, or something along those lines is present, heat is something that is now in the area. So again, like I learned back at university in a physics class, there really is no such thing as cold. Just the absence or lower amounts of heat. We created cold as an adjective to describe the opposite of heat, but in reality if there was a bar graph involved, the bar on the x-axis would represent heat, and on the y-axis, which cannot go negative, there would be measurements like absolutely positively zero heat present (like in that theoretical part of space), and then climb up in whatever increments you want to represent how much heat is present.

@l337tub 10 лет назад

This isn't necessary to get across the point of the video though. While what you said is true about heat and the absence of heat, the term "cold" is still used to describe low temperature, when the video is just explaining that "cold" isn't really describing JUST low temperature, but rather the objects temperature AND it's conduction of heat.

@Baby1961-i5e 10 лет назад

l337tub I know people still say cold but I just thought it might have been a quick line they could have thrown in there about the absence of heat. But I got the main point of the video.

My biggest goal at the moment is to convince people to use different words for our perception of reality and reality itself. This principle goes for all our senses. Sound is just waves.

@talrajavheo7620 11 лет назад

Simply put (and far from complete): Consider your metal atom as a small positively charged ball of protons and neutrons surrounded by the negative electrons. When you then add more and more of your atoms to the mix the way they combine forms a lattice out of the positive cores and a 'sea' of electrons. These free electrons readily conduct electricity and it is easy for them to find others to interact with. With an insulator there are much fewer (ideally none), free electrons, so no conduction.

@sonicpsycho13 11 лет назад

You should see a more rapid change in the thermometer when it contacts the metal, because the metal has a greater thermal conductivity and transfers energy between it and the thermometer more rapidly than the less conductive book. It's this greater thermal conductivity that makes the concrete floor of your basement feel cooler than the carpeted floor. The concrete is removing energy from your body more rapidly than the carpet, and therefore, cooling you faster.

@hoaxygen 11 лет назад

There are neurons in your spinal chord that have a type of memory and function known as a reflex. Whenever you experience something hot, the arc reflex will move your hand away and the signal will go up to your brain where it's processed and stored for future reference. What probably happened was that the context made you expect it to be hot and what you experienced was a memory recall that fired the neuron in the spinal chord in order for your body to protect itself.

@ikannunaplays 11 лет назад

This is what I want to know, thank you for doing a better job verbalising it than I did.

@talrajavheo7620 11 лет назад

The actions of the lattice do, as it vibrates and releases phonons. And electron-electron interaction, causing them to jump up to a more excited state, release photons when they drop. Both are forms of energy, and as you know energy flows from high to low. The important difference here is that conductive materials have more of an opportunity to do so because they have more free electrons. So why the book in this example wants the energy from your hand, it simply is not as easy for it to take.

@PaoloScarabelli 11 лет назад

@jetx998 is right, choosing the laser based on what kind of light the mirror absorbs will make the job much easier. In example if the mirror doesn't reflect ultraviolet light it will be a lot easier to cut with an ultraviolet laser.

@pauljs75 11 лет назад

In terms of how heat transfer works, it gets even more fun when you figure how density affects the molecular jiggling of some fluids. So you can do stuff like freeze things by releasing canned air or starting a fire with a relatively simple piston.

@adrianu9987 11 лет назад

a good example of what the video explains is alcohol. if you pour alcohol (the one for wounds) on your hands, it will feel cold, not because of the temperature of alcohol, but because the alcohol takes the energy/heat out of your hands very quickly. very nice video.

@Jensaw101 11 лет назад

You are correct, temperature is a measurement of the average kinetic energy of a system (how much the atoms in an object "jiggle" as he says) and thus anything 'cold' simply has a lower average kinetic energy than the standard you are comparing it to (usually room temperature). What Henry is talking about here though, is not really temperature. As he explains, we do not feel temperature, this average kinetic energy, we seem to feel the magnitude and rate at which the energy is transferred.

@tennisdrums93 11 лет назад

Thermal radiation is not always in the infrared range. Anything that has a temperature emits thermal radiation. Most things near room temperature emit thermal radiation in infrared wavelengths, but if you make something hot enough it will start to emit thermal radiation in visible wavelengths and glow (heating up a piece of metal is a prime example). Infrared does not directly mean "heat radiation", it just happens that most things you see emit thermal radiation in that range of wavelengths.

@SpaceAndStarsGalore 11 лет назад

This makes so much sense now thanks HENRY!

@Prokasaurus 11 лет назад

When you're outdoors there is heat transfer via radiation through the sun, heating you up even though the ambient temperature is only 25 degrees C Also in an air conditioned room the breeze from the air conditioner increases heat transfer via convection from you're skin, increasing the transfer rate of heat from your body and cooling you down faster as opposed to outside where this effect does not occur if it is a still day with no wind.

@lghal1 11 лет назад

depends on your definition. for example, there is no thing called a "spell particle", its just something that happens when normal chemicals reacts with or nose (yes, i know its a lot more complicated, but i have limited space here). that reaction is what we call smell, so the very definition of smell is what happens when WE smell things. if we couldnt smell, smell would not exist. therefore we must be able to smell things. its the same thing with light and sound

@CultDiscordia 11 лет назад

You make my life better with every video. Thank you

@killerarmycowmovies 11 лет назад

Well, the way the video put it, is it's breaking it down into the technological terms and definitions. Such as I could say "You don't see people you think you're looking at, you see the light reflecting off them into your eyes" Or something relative to that. Breaking down the meaning of temperature doesn't mean you're not feeling temperature, you're feeling what we call temperature due to that.

@myfairjew 11 лет назад

It would be interesting to see a video on minute earth that explains why it feels cold/hot outside based on the three modes of heat transfer i.e. humidity (conductive), wind (convective), the sun (radiant), etc.

@FaDexVengeance 11 лет назад

and, based on one of his earlier videos, the energy equation is the same as the pythagorean theorem, as in E2=m2*c2, but because the mass of energy is zero, it would change it to e=mc2.

@CharlesJayUTA 11 лет назад

Well since pressure is infinitesimally small, temperature is also low. Thats one reason why its colder on top of mountains (lower pressure). So the extremely low pressure would cause gas in your body to lower in temperature (as well as boil oddly). So you would feel cold from the gas in your body, which is in your lungs and ears, as well as dissolved in most bodily fluids.

@EpicUnderscoreJdog 11 лет назад

Well, the heat is a physical change where as the burning is a chemical change. So, the heat you feel from the burning is the stuff in your skin jiggling, where the actual burning, where stuff changes colour and becomes smoke, is an actual change in the stuff that jiggles. That's why you don't feel a really bad burn - the stuff that senses the jiggling no longer exists in its current state as a heat receptor.

@PaoloScarabelli 11 лет назад

@maxxisblitz it is possible to cut a mirror with a powerful laser as no mirror is 100% reflective and some of the radiation will be absorbed by the material and impurities. I think the hard part it so make the first dent, as the surrounding area will be damaged by the heat it will become much less reflective and easy to cut. At this point you will just just need to keep moving the beam slowly enough so it hits areas already damaged.

@shynnsup8383 11 лет назад

Oh thanks, its clear to me now. Suppose after all heat exchange is done the thermometer shows a temperature of 30C and this took 5minutes. At minute 4, the thermometer for the metal will be at 20C and for the book at 15C (example, not accurate).

@Lemon_Planter 11 лет назад

Copycap is right, though, energy and mass are equivalent. Yes, they're equivalent by a factor of c^2, but equivalent just means that they can be expressed in the same units. If you used different units for energy, mass, and c (and therefore all metric distance), and say that c is equal to 1 in new units, and energy WOULD just be equal to mass, the other units would just scale proportionately. One "Zulon" of energy could be EQUAL to one "Krepto" of mass. The point is, they're interchangeable.

@davidimperato7216 11 лет назад

That simply means that too much heat was transferred to your hand from whatever you were touching- even including air. Heat does all sorts of things to you when it burns you- for example, considering we're mostly made up of water, the heat evaporates the moisture in your hand leaving the skin very dried out, peeling and irritated.

@masterblade713 11 лет назад

the sweat will conduct heat away, and then proceed to evaporate, which cools the body, its not so much the sweat cooling, but the evaporating that causes the drop in temperature. though im not sure how, and since im not sure, i wouldn't take my word for it, and recommend doing a Google search to actually find out the true reason

@Darkwhite101 11 лет назад

If you watched the video you'd see we only feel our own temperature, we can't judge the temperature of another object well as we feel the effect it has on our skin, an insulator will have a much lower effect so feel less cold/hot than a conductor despite being at the same temperature. So no, we can't really feel temperature very well.

@DynamicCosmo 11 лет назад

Dear Minutephysics; Your show is very productive and entertaining and i hope it'll stay that way as well. But for this episode I have only one question: are You sure it is correct to say and use the term "temperature"? Because, there is no such thing as "feeling" the temperature; we only feel heat, and heat is the measurement for the amount of energy a certain object emits. Best regards...

@ThadGillespie 11 лет назад

"radiating isn't as efficient as conduction" that's only true for relatively small temperature differences. Conduction is linear (Ta-Tb), but radiation is nonlinear (Ta^4-Tb^4). If you were out in space, there would be about 300K temperature difference and that will draw a lot of heat out of your body, pretty quickly. That is, the parts of you not facing the sun, at least.

@PrimusProductions 11 лет назад

We can feel sound and sight, we just use different words for them. We already have far more than 6 let alone 5 senses, balance, hunger and temperature (mainly linked with touch).

@GwresYnKernow 11 лет назад

I can't remember exactly why, but I know it's something to do with your body's natural emergency reaction system. The body spends far more energy on keeping the bits that are vital for survival (like the chest and torso, where almost every vital organ is located) warm, than it does the bits it doesn't need for survival (arms and legs). This is also why most of your vital organs are in the same place to begin with - easier to keep warm if they're close together.

@ThatGuyYouArent2 11 лет назад

When I freeze-dry something at work, the drying chamber is at around -50 C. Once I open the air admit valve and grab the samples, they always feel as if they were at room temperature, despite having been in -50 C no more than five minutes ago. If it's not completely dry yet, then the object feels really freaking cold. So yeah, I don't need convincing on the book vs metal front. It makes sense. :)

@woduddl0303 11 лет назад

if we are able to slow down the time, we would freeze to death since time is effecting everything. However, since time is in factor of EVERYTHING, freezing to death would be the least things to worry about since the act of slowing down the time just caused the universe to slow down which can have unimaginative chain reactions.

@wisosirius9648 11 лет назад

It's similar to some case of Phantom Pain. Phantom Pain sometimes occurs in amputees who notice their circumstance for the first time. Your body can have a stored memory of a time you burnt your hand, or you have seen others burn their hands because of this scenario. Your body gets such raw adrenaline coursing through you that you assume it is actually hot. This also plays on other cool things like assumption. When you assume something, sometimes the brain takes the assumption for real events.

@RisePatriot 11 лет назад

Great video, scientific and interesting. Now the practical side: A human generally has no need to sense small differences in temperature. As long as we can sense DESTRUCTIVELY hot or cold temperatures then our senses are functioning as intended. As long as we can see actual danger, the fact our eyes are tricked by certain patterns is academic entertainment.

@3llay 11 лет назад

@GkMrBane 11 лет назад

So in responce to myself the answer is: Its not possible anyway since time is a constant and the only thing that can speed up or slowed down is the preception of time not time its self. And to get the effect of moving through time faster than the space around us we would need to be able to move faster than any ground vehicle is currently capable of moving If our bodies were able to achieve this speed I think that we would most likley boil inside our skin from all the heat. Thanks for responces

@Lokheit 11 лет назад

Great vid but you didn't include one of the most common examples when this topic is brought: If you put a hand in hot water and another hand in cold water, and then you put both hands in mid temperature water, each hand will feel it the opposite way. This is explained by what you said in the video: The hot hand is giving energy and the cold hand is absorbing the energy so each one feels it different despite the water is the same temperature for both.

Color is a sensation. Lightness, loudness, slipperiness, those are all sensations in our brain made by organs that recept inputs (wavelength, intensity of light, texture of material). So, yes, color exists, but it exists in our brains.

1> Both yes, and not really. 2> Yes, by definition. 3> Yes, unless you mean figuratively.

Or the lack of pressure around you... Allowing you to expand very rapidly... Don't forget about that...

If you slow down time in a local area, it will not be slowed by your own perception (nor the space where your body resides). In essence, even if time was slowed down by a factor of a billion in your room, you wouldn't notice anything different locally. Outside of your room, 34 years or so would pass every second. You just wouldn't notice it, and it would affect the atoms in your body Unless you stuck your hand outside of the temporal field.

This a classic Sherlock Holmes style question. Carpet and tile work as well, they are the same temperature, but one sucks your heat out faster than the other. The objects want to all be the same temperature as your feet, so it sucks away. That's also how we get "room temperature".

My class and I watched this in class today, best middle school science class ever.

We've never measured the temperature of space to be 0 Kelvin (which is -273.15 degrees Celsius). The absolute scale of 0 Kelvin comes from the fact that at 0 kelvin, the pressure of all gases, no matter what type are equal. So far 0 Kelvin has been impossible to produce in labs, although we can achieve very close to it.

Seconded- True heroes, these guys are.

It's correct that energy can be converted to mass and that they can be seen as the same thing, but you guys are confused on a couple of things. First, it's only the 'c' that's squared. The equation is more clearly written as E=m*(c^2). Second, MidnightDaystar is having a bit of trouble factoring and FOILing. If I could see your work I could tell you what happened, but this is youtube, not a tutoring session so I'll spare the technicalities.

Your body is conditioned into a stimulus-response pair. It's classical conditioning. Heard of Pavlov's dogs? When a bell was rung food was presented and they drooled, eventually the bell itself made them drool without food. This has happened to you: You touch a "hot thing" and the heat makes you flinch, so on this occasion, touching the "hot thing" makes you flinch even without heat. Sorry if this is unclear, but I had an AS Psychology exam on this recently and I'm excited to know it :P
