Abstract: Liquid crystals are states of matters featured by local anisotropy typically generated by rigid molecules. The description of local anisotropy leads to distinctive ingredients in liquid crystal models. We discuss the following topics: symmetry, order parameters, free energy, relations of molecular parameters and coefficients in the models, hydrodynamics, entropy term and closure approximation. In particular, the most computationally challenging problems always involve the entropy. We propose an elementary-function substitution of the original entropy, called the quasi-entropy, that is prospective in resolving these problems.
