Although I have no idea what one can do with this I thought maybe someone with more scientific ability might try a crack at it?

Scientists in Colorado Create New Form of Matter Under Ultracold Conditions

BOULDER, Colo. (AP) - Scientists say they have created a new form of matter from a half-million potassium atoms chilled to within a whisper of absolute zero, the coldest possible temperature.

Fermions represent a class of elementary subatomic particles that includes electrons, and they are among the building blocks of atoms and molecules. According to a law of quantum mechanics, no two identical fermions may occupy the same quantum state.

On Dec. 16, researchers at the joint lab known as JILA used lasers to trap the small cloud of potassium atoms. By limiting their natural motion, they cooled the atoms to 50 billionths of a degree above absolute zero, or minus-459 degrees F.

Normally, subatomic fermions in these atoms would repel one another.

But the researchers said that when they applied a magnetic field to the ultracold atoms, the atoms briefly matched up in pairs and created a condensate, behaving in a coordinated wave pattern.

What do you make of this - opinions?

this article from cnn explains the use they were aiming at when they did this, it explains pretty well what they did also.

www.cnn.com...

WASHINGTON (Reuters) -- Scientists said on Wednesday they had created a new form of matter and predicted it could help lead to the next generation of superconductors for use in electricity generation, more efficient trains and countless other applications.

The new matter form is called a fermionic condensate and it is the sixth known form of matter -- after gases, solids, liquids, plasma and a Bose-Einstein condensate, created only in 1995.

All known particles are either fermions or bosons. Fermions have half-integral quantum numbers of spin: 1/2, 3/2, etc. They obey the Pauli exclusion principle in that no two fermions can occupy the same quantum state. Examples of fermions are the electron, proton, neutron, and quark.

No two electrons in an atom can have identical quantum numbers. This is an example of a general principle which applies not only to electrons but also to other particles of half-integer spin (fermions). It does not apply to particles of integer spin (bosons).

The Pauli exclusion principle is part of one of our most basic observations of nature: particles of half-integer spin must have antisymmetric wavefunctions, and particles of integer spin must have symmetric wavefunctions

so in other words, the fermion particles in the atoms(eg electrons) are not repelling each other, so they can be paired up. i am not so sure about the matter behaving in a wave like pattern. that is kind of beyond me (just trned 14) maybe sumone else could answer this question?

for a 14 year old you are amazingly knowledgable of physics, to bad there's not more people your age with that kind of intelligence.
