Materials Science Mystery Of 'Hidden Order' Solved:

Has science taken a wrong turn? If so, what corrections are needed? Chronicles of scientific misbehavior. The role of heretic-pioneers and forbidden questions in the sciences. Is peer review working? The perverse "consensus of leading scientists." Good public relations versus good science.

Materials Science Mystery Of 'Hidden Order' Solved: How A New Phase Arises And Why
http://www.sciencedaily.com/releases/20 ... 091900.htm

Four physicists from Uppsala University, led by Peter Oppeneer and in collaboration with John Mydosh from the University of Cologne, who discovered the hidden order 24 years ago, show through large-scale calculations how the hidden order occurs. Extremely small magnetic fluctuations prompt changes in the macroscopic properties of the material, so an entirely new phase arises, with different properties.

"Never before have we seen the so-called ‘magnetic spin excitations'produce a phase transition and the formation of a new phase. In ordinary material this excitation cannot change the phase and properties of the material because it is too weak. But now we have shown that this is in fact possible," says Peter Oppeneer.
I was thinking about phase changes a few days ago and happened by this article tonight. (It always happens this way) I think this property is existent in more common phase changes, and sublimation, specifically with 'photons' (which I don't think really exist) causing the water to evaporate. This process could be implimented by plants through photosynthetic process. The relationship with the water cycle is key. Don't know where this should go, since any blathering I submit will warant this topic be degraded to mad ideas, but the original article may hold some EU merit.

Anyway enjoy.
