      You don't ware gloves while dealing directly liquid nitrogen because it will not actually contact your skin because it will boil off before it does and if you ware gloves it will freeze the gloves then that will freeze your skin, you do when you are handling solid things that have been cooled by it though polistiren or other poor thermal conductors should be ok to handle for short times due to it's poor thermal conductivity.
      Which I think the model was polistiren although that paint will have better conductivity probably.

    Stick a little fan to it, and you don't need to push it.
    Connect that fan to a remote controller, and you can drive it around.
    Connect multiple fans, and make the track fatter, and you have a car that can steer.
    Make multiple cars, and you have a race track.
    Imagine that: a mobius strip superconductor racetrack. Since you use superconductors, you could make it go ridiculously fast. If that isn't a cool idea for a toy, I don't know what is.

      Using carbonnano tubes we could make quasi super conductors. Not really superconductor, but something like 1000 times better than cooper Pair it with a small battery and circuit you could make something that works the same way with out using superconductors.
      We can do it today to with copper coils, but the the battery will run out in 2 minutes, with carbon nanotubes it will last for hours.
      There is actually toys that work this way.
      Levitron World Stage Levitating Globe - www.earthtechproducts.com
      The magnet is in the glob insted, and there is a coil doing the same work as the super conductor. A small transistor feed in losed power into the coil to it act the same way as a super conductor.
      Also, Transrapid Magnettrain, works the same way, no superconductor. Thow SC-maglev magnettrain in Japan doe use superconductor.

      "1st:super conductors that work on room temperature"
      Already done. But we don't know how to produce it pure (only a small part of the conductor is the superconductor, giving you a small jump in resistance when going above Tc of that part which is superconducting).
      We don't know how to cheaply mass produce it.
      The usual problem of high temperature superconductors (all the ones that work with liquid nitrogen cooling) remain. Superconductors can't withstand very strong magnetic fields, or the superconductivity disappears. Type II superconductors form magnetic vortices, that channel the magnetic field in "pillars" of normal non-superconducting material, in a sea of superconducting material; this allows the critical field to be higher before the superconductivity breaks down. For high temperature superconductors this critical magnetic field tends to be too low for most interesting applications, even if it's a type II superconductor.

(for those that don't know graphene is a single sheet of carbon atoms arranged in a hexagonal patterns for maximum efficiency and its used as the walls of a carbon nano tube).

      *****, it would be a rough halt, but probably not so sudden as to threaten the lives of passengers. While you lose the zero friction, the movement along the plane doesn't go anywhere. Imagine a very heavy metal piece landing on a metal surface while in motion. The gravity is great, but it would still keep going, producing lots of sparks. But then of course, here we don't have the same correlation between inertia and forces of attraction. Can't tell for sure.

      In space you aren't "cooling", in space you can't reliably use enviroinment matter to establish a temperatural equilibrium, because there is barely any enviroinment matter.
      So if you're cooling - space matter can't warm you and if you're heating, space can't cool you.
      You have only 2 ways to share thermal energy - light emitting (and absorbing) and phisical contact. On the planet surfaces, second way is largely inflated due to you always being in contact with enviroinment matter (air, water, soil), in space there is none of it (virtually none of it) so in space to cool down you have to emit energy.
      Or so is my understanding of it, there are good reads on this, probably, that are worded better and have more recent facts than what's in my posession, so i recommend checking those.

    • @ChemicalRefugee
      @ChemicalRefugee 10 ปีที่แล้ว +6

      *****
      Superconductivity does not happen due to 'cooling' it happens at a certain temperature range. Cooling (the loss of thermal energy) is irrelevant. Now, in space (in a shadow with no infrared hitting an object to warm it) the basic temp is minus 455 degrees Fahrenheit (about 2.7 Kelvin). Things in space are subject to extremes of temperature.
      Here on the earth we use liquid nitrogen to get superconductors to work, because it is the cheepest method we have (liquid nitrogen is cheaper than beer). On the other hand, in space, in a shadow, there is no thermal energy past background (again - 2.7 Kelvin). There is no atmosphere in space to retain or to conduct or retain heat.
      A thermocouple can generate electricity quite well in space, because all it takes is an object with the cold of space on one side and the heat on the other side... with a thermocouple running through it. A lens or a set of mirrors on one side (the hot one) makes it easier ot get it HOT on the sun-ward side, given the extreme cold of space on the other side.

    • @danieleronchetti1314
      @danieleronchetti1314 2 ปีที่แล้ว +1

      Correct me if I'm wrong: you are wondering how it is possible to easily move the superconductor (SC) inside a magnetic field while having 0 resistence (R). This because a 0 R conductor (perfect conductor) moved in an external magnetic field would generate infinite eddy currents.
      I would takle this from two sides:
      First, the 0 R condition (also called perfect conductor) is not sufficient for infinite eddy current as @Jensen is suggesting. With 0 R you actually have persistent current, meaning that a current generated inside the perfect conductor will never cease to exist, but the intensity of this current will never be infinite. You would need an infinite change of flux to induce an infinite current, which you can see is impossible. Otherwise if a finite change in flux would generate an infinite current this would solve the energetic hunger problem.
      On the other side the SC is NOT a just magnet, it is way more than that. A SC shows the Meissner effect, namely NO magnetic flux can enter the SC. Similarly to how NO electric field is present inside a conductor (in static condition). And how can this happen? We can think that the SC generates a magnetic field such that the total magnetic field inside itself will be zero. Therefore when you move the SC this will modify the field that is generating and when you leave it the new field configuration will again be such that the internal field is zero. In this way you can see that there happen no change in the magnetic field flux inside the superconductor, because the field inside has always been zero, this implies no eddy currents.
      Actually there are also surface effects happening which complicate the picture, but the final result is similar.
      I hope that this intuitive picture would help you!!!

    I've got 2 ideas about this:
    First: Can you use this to set up a kind of REALLY long lasting newton's cradle, by just putting a bunch of these on a sloped track (basically a parabolic track where the magnets could move back and forth, pushing each other via magnetic repulsion? If you'd do that in a vacuum, that would mean they would continue on until all the kinetic energy is transferred to heat via induction in the neodymium magnets. I could imagine it'd take REALLY long for that kind of Newton's cradle to stop
    And the second: Can't you make something like this with a super strong magnet, with a weaker magnet attached to that, with their poles facing each other? Of course that'd be if you would make sure they are attached really strongly. If you'd put a magnet on top of that, it would be attracted by the strong magnet when far away, but repelled by the weak one when close by. So to illustrate, with lowercase representing weak and uppercase representing strong poles, it would basically be this: (n-s) (s-n N-S). The first magnet wouldn't wanna flip around to face the weak magnet, because it'd then face the wrong way for the strong magnet, but it can't come closer to the weaker magnet because it's repelled by it. I'd imagine there could be a situation where the ratios are exactly right and you could levitate something with that, right?

      There exists something called Earnshaw's theorem. It's a mathematical statement that pertains both to electrostatics and magnetostatics, and the gist of it is that you can never make up a distribution of charges or magnets that will allow a test charge/magnetic dipole to remain in stable equilibrium. Your arrangement, for instance, would only work in 1 dimension, like if you put the magnets in a pvc tube. The minute you allow sideways motion it becomes unstable and they all stick together.

      overTIMe the current trains are maglev, which use alternate magnets to both attract and repel the train, effectively hovering it in the right place, whereas the superconductor resists movement away and towards the magnets holding the charge, again locking it in place.

    • @PastelitoPapi
      @PastelitoPapi 11 ปีที่แล้ว +3

      The parts list was fairly straight forward. You'll need some material to make your track out of. It could be a number of different things like wood or aluminum. Then you'll need the magnets. There are going to be a lot so don't think it's a bit strange when the tab starts to go up. Then you'll need glue to keep them together and I recommend you have a vice. That'll keep all the magnets in place since you will be forcing the same poles to stick together. And lastly you'll need liquid nitrogen. If you don't have any the best bet is to go to a local school and explain what you're doing. Usually gas companies can be a somewhat skeptical as to why someone is asking for liquid nitrogen. Oh, and whatever you want to ride around the track. I had a hot wheels car laying around under my bed so I drilled a space in that and used it. I think between the superconductor and the magnets, that's what we spent most of our money on. The size of the track (if you choose to use one) will obviously dictate how many magnets you use. My dad is a chemist and physicist for a university so he got most of the the stuff on the school budget and used it later. Mainly the superconductor and the liquid nitrogen. But overall it's probably less than $300. But don't let that number scare you. I did mine and it was pretty huge. We actually had to break it up into separate parts to move it into the school. So yours could cost significantly less.

    To me the magnet is the super conductor, (able to conduct both positive and negative portions of magnetic waves) the material you are using is a semi conductor (its ability to conduct the positive portion has been frozen out), therefore the magnet is both repelling and attracting the semi conductor resulting in its elevated state. If you draw a line across the top of your round magnet you will see that it spins as you drop it into the copper tube, both the top and bottom are conecting to the tube the magnet is passing its energy into the tube and absorbing it back out of the tube from the opposite side.

      tallswede80 Excellent question. The Royal Institution is a charity based in London UK, dedicated to connecting people with the world of science through events, education, and videos like this. We’ve been around for more than 200 years, have been the home of some of history’s greatest scientists, and aim to make people think more deeply about the wonders and applications of science.
      There’s quite a lot more to the story, if you’re interested: rigb.org/our-history

    At 3:23, do we have a wrong arrow? North should point down for a clockwise current loop. The top pointing arrow is south, should be pointing inward.

    Nitrogen is safer with no gloves & your warm hand dispels it fast but if u spill on a glove it freezes on your hand 😳🔦🐱‍🐉fook
    ive watched many videos of people pouring nitrogen on there hands & didnt do chit :) BUT you dont hold your hand in it
    Nitrogen is a bit like fire like > pass your hand over a flame as u can with nitrogen - They both burn but depends what you do 🤪👉 🤵😲

    Is it safe for him to handle liquid nitrogen with his bare hands?

    • @IronJoeJac
      @IronJoeJac 10 ปีที่แล้ว +12

      Perfectly safe, it would evaporate before it touches him.

      It's called the LedenFrost Effect; If you have ever put a drop of water on a hot pan, you'll notice that it'll actually move around on a "cushion" of vapor before completely vaporizing. Here, the liquid nitrogen flows off his hand as his hand is very "hot" compared to it.

      @iknowsstuff 10 ปีที่แล้ว +11

      as long a its a spill there is no problem if you were to dip your hand in for a longer period then yes it would be bad, the reason you normally put gloves on when handling liquid nitrogen is to protect from intense cold of the flask and other surfaces not the nitrogen itself

    Do you see that little Red box beneath the title of this video? You know the one that says SUBSCRIBE? I certainly see it. And that's the button that I click when I subscribe. I chose to watch this video because of my interest in the Mobius Strip. Really wanted to see what you had to say and do. But your request for my subscription at the lower left corner and the box at the top with the elusive X so I can't get it off screen blocks out things. I know you have a lot of subscribers already, so obviously it doesn't bother them, but I'm one of those 'visual' type people. Can't stand distractions. I know. It's a personal problem -- which I deal with by not subscribing because I'm afraid that all of your videos are covered up in requests. Seriously. Not a troll I don't live under a bridge. But now I've got to go to the Library and see what I can find THERE on the subject. If the blocks were just put someplace so we could X them out after being made aware there's more to see, that would be so helpful.

    • @TheRoyalInstitution
      @TheRoyalInstitution  8 ปีที่แล้ว +5

      You make a reasonable point. We've replaced the old annotations with TH-cam's updated and less intrusive 'cards', so the hopefully you'll be able to enjoy the video in all its glory, unhindered by those clumsy boxes now :) Thanks for watching!

    • @TheAndroia
      @TheAndroia 8 ปีที่แล้ว +1

      The Royal Institution Thank you for your polite response to what I now think was a curt suggestion. I plan to revisit your video and enjoy it with relish. Like the girl with two left feet who so wants to be a dancer, I am a non-mathematic person who so wants to understand the world of physics and all things science. And because of some silly sci-fi book I read as a kid the Mobius strip has always fascinated me. I love science fiction and when I read it I like to be able to distinguish the science from the fiction. Thank you for fixing the boxes.

    In terms of feasibility, how does the energy required to keep the magnets cooled to such an extreme compare to the energy efficiency gained by eliminating track friction?

    The thing these guys are experimenting with, superconducters, will be incredibly useful if they can make them work at any temperature. Computers would be incredibly fast, our electrical problems would be fixed. So these guys are actually doing something important

    The idea of having a superconductor that reaches it's critical temperature at room temperature or higher, could be revolutionary.
