the religious debate is getting boring - lets debate something else, since you are concerned I am "breaking the rules". Lets talk sub-dimensional physics-

Hexagonal HoMnO<sub>3</sub> is a frustrated antiferromagnet (T<sub>N</sub>=72 K) ferroelectric (T<sub>C</sub>=875 K) with a rich magnetic phase diagram consisting of multiple temperature- and field-dependent phases. Previously observed anomalies in the dielectric constant at magnetic phase transitions indicate strong coupling between the ferroelectricity and the magnetism. Such coupling is of great interest for both fundamental physics reasons and for possible technological applications, but is not yet well understood. Neutron scattering is a versatile and powerful experimental technique, especially for magnetic systems, and is used to probe the magnetic properties of HoMnO<sub>3</sub>. Neutron diffraction measurements in a magnetic field reveal new intermediate-field phases at low temperatures. Inelastic neutron scattering measurements are used to establish the primary magnetic interactions, and demonstrate that the spin dynamics in HoMnO<sub>3</sub> are well described by a simple two-dimensional nearest-neighbor Heisenberg antiferromagnetic exchange J=2.44 meV and a temperature-dependent anisotropy D.

I borrowed it from R-man, kinda scared, don't know where it's been....

I googled it just to see what it would say. It is a paragraph word for word from a seminar hosted by this guy from the physics dept. at the University of Toronto.

On a side note, that post in the religious forum reminds me of the way that forum used to be, before they closed it to discussion and we could only post religious freebies in there. SO, I'm staying out of it for now on.

of course it is a cut and paste! I know as much about physics as some people know about .....oh, never mind! just trying to lighten the mood around here !:withstupid:

LOL...I was trying for the life of me to figure out what in the world it was even about. With all of the HoMnO<sub>3</sub>'s and (T<sub>C</sub>=875 K)'s I couldn't make heads or tails of it! :rolling
