Pingie: HTTP:: Magnetized Gas Makes New Kind of Physics Possible

HTTP:: Magnetized Gas Makes New Kind of Physics Possible
--------
Atomic physicists were recently puzzled to discover a type of gas that could have the ability to start a new type of physics all by itself. The chemical exhibits some very peculiar properties, when its initial conditions are changed. For instance, when its temperature is dropped to the ultra-cold range, it begins to be magnetized, very much in the same way metals (including nickel and iron) do when placed near a magnet, ScienceNow reports. The scientists say that they could potentially use their newly discovered gas to rearrange the messy atomic structure within solid materials. However, not all the scientific community shares their enthusiasm. Some say that the team has not seen what it claims, and that the results of its investigation are still inconclusive, Science Now adds. Behind the research were scientists at the Massachusetts Institute of Technology (MIT), led by experts Gyu-Boong Jo and Wolfgang Ketterle. They analyzed a cloud of lithium-6 atoms, because of the!
spin similarities that these specific structures had with electrons. Though no one knows for sure, it is widely believed that magnetism inside a solid, for instance, is given by the way electrons arrange themselves in their orbit around a nucleus. This theory is based on the Pauli exclusion principle, a quantum-mechanics idea that s...
