      They are public domain videos which I downloaded 15 years ago - I can't remember the site I got them from. The sound on them was quite bad and I had to do quite a bit of processing to improve it. I did physics at university and this happened to be an area I was interested in, along with superconductivity (which is closely related).

  • @treatb09

    Ive speculated this. That superfluid helium to experience inertia must break superfluid effect at a frequency. So the boundary layer is experiencing that break before returning to a superfluid state. And on different gravitational spectrums. We can experience the fan turning or not. But the physics is insanely complicated.

    Motor experiment needs to be repeated with the chamber evacuated. I allege that the paddle wheel could be dragged around by induction from the rotating magnetic field, or from diamagnetic hysteresis effects. If this is true, the vacuum experiment will show this as there is nothing in the chamber.

    • @Zantorc
      @Zantorc 2 ปีที่แล้ว

      The paddle is made of wood for that reason; (BTW wood is paramagnetic rather than diamagnetic, with a relative permeability 1.00000043). The speed with which the paddle started to turn leaves little doubt that it was due to bulk flow of the liquid helium and not due to any magnetic effect on the paddle.

      "I wonder if we should see the fountain effect with all superfluids." Yes I think you would, though demonstrating it with anything other than Helium could prove to be a problem - other materials require temperatures measured in nano degrees K and has only been achieved with few hundred thousand atoms.

      @@mykulpierce When you look at it what they observed was superfluidity in 14 to 16 molecules of hydrogen. You won't see it in bulk because hydrogen freezes, unlike helium which doesn't freeze solid under normal conditions. Having said that, under enormous pressure (such as the interior of Jupiter ) it is possible to form metallic hydrogen and there may be an ordered states of that which involve superconductivity as well as superfluidity. The interior of neutron stars is another place where superconductivity and superfluidity are likely to coexist.

    This is some evidence based material proving that an elements with a specific atomic weight surrounded by more of the same element with the same atomic weight can possess different but predictable properties. Application of quantum physics in real world. The same should/would apply to metals of periodic table of elements. How do you form metals of a specific element with all atoms possessing same atomic weights together? Each specific atomic weight class for every specific element would have different properties or slightly different properties, but predictable after observed. If these metals could be produced, the applications for use in technology are mind baffling. I am not a physicist, I hope people smarter than me are looking into this right now. Unfortunately, research like this is typically done behind closed doors in secrete. I understand why, from my limited perspective, but still unfortunate.

      It is a quantum mechanical phenomena, there is no possible classical explanation. The superfluid component of the helium has to be treated as a single particle not as individual atoms because individual atoms no longer exist in the superfluid state. "Those who are not shocked when they first come across quantum theory cannot possibly have understood it" - Niels Bohr. “Not only is the Universe stranger than we think, it is stranger than we can think” - Heisenberg.
