[quote]A team of researchers from Cologne, Munich and Dresden have managed to create artificial magnetic monopoles. To do this, the scientists merged tiny magnetic whirls, so-called skyrmions. At the point of merging, the physicists were able to create a monopole, which has similar characteristics to a fundamental particle postulated by Paul Dirac in 1931. In addition to fundamental research, the monopoles may also have application potential. The question of whether magnetic whirls can be used in the production of computer components one day is currently being researched by a number of groups worldwide.
When a magnet is divided, a new magnet with north and south poles is always created. However, a monopole, i.e. a north pole without a south pole or a south pole without a north pole has not yet been discovered. In the current edition of the journal Science, researchers from Cologne, Munich and Dresden describe the discovery of new type of artificial monopole in a solid, i.e. particles, which have similar characteristics to monopoles, but which only exist within materials.[/quote]

Motherfucking magnets, bitch.
Translation: Dirac predicted that there might be a particle out there which does not have a magnetic north and magnetic south pole, but only one or the other. We've never found one, but these guys created something which behaves like it inside a material.
Where's the translation??

I'm with this guy
Every time these scientific breakthrough news stories get posted, I never understand them but it sounds like good news so I'm happy anyway
This is absolutely awesome, despite the fact I barely understand it.
However when I read monopole I keep thinking of this bastard:

Added to OP. Let me know if I should clarify anything else in it.

Clear and concise. TYVM
[QUOTE=sYnced;40860020]Where's the translation??[/QUOTE]
Magnets have a north and south, the magnetic inside this material only has one but not the other.
so these are more quasiparticle excitations, right: what makes them different from the other reported things-which-act-like-magnetic-monopoles?

that's the weirdest thing I've seen in ages. they're like little slices of the B-field inside a wire. how the fuck does it propagate?
[QUOTE=Trumple;40860320]buh-but Maxwell's equations told me....they....Maxwell? :([/QUOTE]
They can be modified to include magnetic monopoles.
[QUOTE=Trumple;40860320]buh-but Maxwell's equations told me....they....Maxwell? :([/QUOTE]
Apparently Maxwell believed that something akin to a 'magnetic charge' should exist so that his equations for the electric field and magnetic field would have symmetry (or so a lecturer of mine told me a few weeks ago). Free 'magnetic charge' would add what he considered a missing term to his equations.
Right, so how exactly does a monopole function?
I'm just thinking of the classic north-south bar magnet with some iron filings showing off the magnetic field, so what the hell would the magnetic field for a monopole look like?
[QUOTE=sYnced;40860020]Where's the translation??[/QUOTE]
If you surround the magnet with a gaussian surface you will find that the net flux is non zero so its kind of a big deal.

This is actually a severe problem, our society is separated from science due to the fact that it takes a large investment in order to understand it (invest of time or something), the small amount of things that readily translate new breakthroughs into laymans terms leads to our society not really giving a fuck about science until it directly effects it. This, in turn, leads to a smaller amount of people interested in STEM career than should/could be.

It would look exactly like the electric field diagram for a single electrically charged particle.

Now we need just electric field dipoles and we have a complete set
This is awesome, for a second I thought they discovered the particle but this is the best next thing :D
Everything will be found eventually, even proton decay.
Science is awesome.
Am i smart if i understood it without the capsule translation? :v:
This sounds big, I'm not rather keen on the potential use of monopoles, but does the falstad simulation of one accurate to the magnetic whirls (It instead simulate opposing current loops to focus the outwards field from a current loop 'cube' )?

Total matter-to-energy conversion reactors, any day now.

How did you jump from magnetic monopoles to that
metamaterials, fuck yueah
This is like holy shit if reproduced.
Doesn't some doomsday event pertain to magnetic monopolies?
[QUOTE=No Party Hats;40864963]Doesn't some doomsday event pertain to magnetic monopolies?[/QUOTE]
No?
Robotics;Notes or not idk ..
Those magnetic swirls? They're called skyrmions.
Damn that's cool.
[QUOTE=No Party Hats;40864963]Doesn't some doomsday event pertain to magnetic monopolies?[/QUOTE]
I could've sworn there was something like that on Exit Mundi, but I can't find it now. It does sound familiar.
[QUOTE=No Party Hats;40864963]Doesn't some doomsday event pertain to magnetic monopolies?[/QUOTE]
Yeah pretty sure that was anime
never heard of the anime, seems p. cool though
but uh, i was thinking of what people were predicting the LHC to create at first.
Magnetic monopoles, vacuum bubbles, that stuff
