    Sixth state of matter: Fermionic condensate

    you've also got that state of matter which i forgot what it is called but neutron stars are made from it...where all atoms strip down to a neutron superfluid

    sorry but can anyone here explain Bose-Einstein condensate and fermonic condensate to me?
    i read it somewhere it rings a bell but it makes no sense to me :p

    Sorry to barrage with questions, I hope it's not too much trouble. To quote:
    Why would that be possible? Is it just saying that they could levitate by using resistance that didn't lose energy? Or something to that effect?

    baryon degerate matter.
    Click on the link in Monique's last post; it's a good summary. For further info, google on Bose-Einstein condensate, and chose one of the articles to suit your level.

    Seventh: dark matter (may be more than one kind :wink: ).

    BEC is a supercooled particles of bosons, which act as a single molecule. The fermionic condensate is made up of the other kind of particles: fermions.

    What I don't understand: how do rubidium atoms belong to the bosonic class? I thought fermions are regular particles as we know it and bosons are force-carrying particles?

    Its simply a matter of friction. A train that doesn't touch the tracks has only air resistance to worry about.

    I see...I get that part...but I jsut don't get how a superconductor (to my understanding, something that can carry energy close to 100% efficiency) could make something have no friction.

    Well, if that superconductor has magnetic properties..

    the train will have no friction because it is not touching the tracks, but floating ABOVE them.

    I understand that it wouldn't have friction, because it would levitate. What in the world would make it levitate? Sorry if it's a dumb question.

    PS: Is that you in your pic Monique? Lookin sharp!

    It levitates due to electromagnetic repulsion.

    Bosons are particles that behave according to Bose-Einstein statistics. It turns out that this is equivalent to saying that "bosons are particles with an integer spin" (as opposed to being 1/2, 3/2, etc).

    When atoms (which are, in general, fermions) form pairs, they may do so in such a way that their spins are "aligned" and add up to an integer, which makes the system behave as a boson.

    This is what I found on the web:

    I wonder what would happen with someone with a pace-maker if they come close to a maglev (magnetic levitation) train?
