Perfect crystals show translational symmetry which allows the application of group theory.
But unfortunately, in our field, the considered systems are large and disordered. Disordered systems in solid state physics are for example glasses, resins, aerogels, cross - linked polymers and others. Since these systems do not show translational symmetry like crystals, they have to be treated with different methods. It means that an object looks the same on many different scales of observation. Or if you take photos of cauliflower and you do not know the magnification factor, you could not say, if the photo is taken from the whole object or from a small part of it.
