Paradigm for the Higgs mechanism[edit source | edit]
The Meissner effect of superconductivity serves as an important paradigm for the generation mechanism of a mass M (i.e. a reciprocal range,
where h is Planck constant and c is speed of light) for a gauge field. In fact, this analogy is an abelian example for the Higgs mechanism,[4] through which in high-energy physics the masses of the electroweak gauge particles, W± and Z are generated. The length 
is identical with the London penetration depth in the theory of superconductivity.[5]See also[edit source | edit]
Meissner effect consists of the range of the Fields ( like the magnetic field here) becoming finite, so quantized in the fundamental level, and which amounts to its particles being rendered massive.

Meissner effect is pretty cool actually. Every time I watch this kind of applications I feel amazing. Imagine the revolution in the transport field for instance, in the future, the new cars will probably use this kind of effects.
What I really like about this effect http://goo.gl/kug93 is it's similarity to the Higgs Mechanism at a phenomenological level. (yeah, I know, Higgs again !). Both of them (Meissner & Higgs effects) describe somehow the generation of the Mass.
In this video, you are probably looking at an indirect evidence of the Higgs Boson! ^^

Explain how this relates to the Higgs Boson please? I'm only a wannabe physicist :p

+Fahad Ayaz Actually, Meissner effect consists of the range of the Fields ( like the magnetic field here) becoming finite, so quantized in the fundamental level, and which amounts to its particles being rendered massive. However, when people unified Electromagnetism with the Weak interaction, the Higgs mechanism was created after to describe what we call now the spontaneous breaking of symmetry , which means the generation of Massive particles(W and Z boson of the weak interaction) from massless particles(photons of the Electromagnetic interaction).

Haha I'm going to have to do a whole bunch of research on what you just said!

I am sorry, this is the best thing I could do ^^ But keep in mind that both of them are treating the generation of mass from zero.

The problem is that you're still explain at too high a level that I don't understand most of it. I do want to learn more about it, but i don't want to waste your time.

+Fahad Ayaz I apologize, maybe we will have the chance to discuss and check this out soon again. I've been busy lately and I ain't doing Hangouts, but as soon as I will have time, we will enjoy learning physics and stuff together :)

+James Traver, Jr. For the Meissner effect check out some Advanced Quantum mechanics books and superconductivity. And for the Higgs physics, there is no way to avoid learning Special relativity and Quantum mechanics first, to learn then Quantum field theory. But a book like this one is pretty interesting. http://www.amazon.com/Quarks-Leptons-Introductory-Particle-Physics/dp/0471887412 Have fun dude :)

+James Traver, Jr. For more general books for non-physicists, you can always read Hawking's, it's always fun to read his books.
Otherwise, there are some amazing articles of Ed. Witten (maybe the greatest physicist alive) about the Higgs, especially Hunting the Higgs & When Symmetry Breaks Down. Check out the articles in this link http://www.sns.ias.edu/~witten/

+James Traver, Jr. You are most welcome. My favorite Hawking's book is A Brief History of Time. Then there are two amazing book The Universe in a Nutshell & The Large Scale Structure of Space-Time :) His last book The Grand Design is okay, but actually, it didn't add something new.
Brian Greene is awesome and clever too in his books, check out The elegant universe, and The fabric of the cosmos, Space, Time and the texture of reality and The hidden reality, parallel universes & the deep laws of the cosmos . I wish you will find them interesting.
However, here's a post of mine with a link to an amazing site of articles of Theoretical Physics https://plus.google.com/u/0/100264010813126229552/posts/f5F91Ayn2aH Enjooooy :-)

I'm going to have to research the physics behind this, but it sure does look cool. This is the kind of stuff that should be on TV inspiring kids to become physicists.

+Amine Benaichouche Can you explain why the superconductor disk does not drop when the magnetic bar is turned upside-down? Is the repulsion force from the magnet becoming attraction force then?

Handling a super cooled super conductor or any other object at about -190°C with bare hands doesn't give you cold burns? Or you must touch it for slightly longer periods of time?

I thinck it's not about attracting or repelling. The magneting field travels around the superconductor and just locks it in that position. I thinck for a very powerfull magnetic field you will need a lot of force to position or reposition the superconductor. :)))))

+Tri Do I think +Razvan Zaharia's explanation is right, and try to look at the Magnetic field as a Field filling the spacetime and forget the image of the Magnetic interaction as a Linear interaction. The Magnetic field in this effect enclose and surround the object.

+Razvan Zaharia Good remark. Yes, it is possible to handle briefly frozen objects in Liquid Nitrogen, but I say briefly, the body creates some kind of an insulating vapor layer for few seconds, this is the so-called Leidenfrost effect http://en.wikipedia.org/wiki/Leidenfrost_effect
