  I have spent the whole day reading...spin glasses, dipolar glasses, relaxors and nonlinear behavior. Hmmm, my brain is probably gone and that's probably the reason why I am thinking how amazing would it be to consider the semantic and philosophical approach of choosing the names for these stuff. So spin glasses are really things that spin around (instead of their spins spinning around! ) and dipolar glasses have a double personality, relaxors are just too relaxed to respond or kind of respond lazily, nonlinears are the one that behave out of the line... Sometimes, I think the basic science would be so much easier if we just change our approach to it. ... Yes, my brain is completely gone.
