Nematic universality

In this work we will present theoretical arguments that explain why the nematic phase exhibits a universal behavior encompassing its entire range. By considering that the physical properties of the nematic molecules can be written as a product of two distinct terms, being the first a compound dependent term and the another a function characterizing the nematic phase, it will be shown that it is possible to remove from the experimental data the particularities characterizing an specific compound and a universal behavior is obtained. Furthermore, it will be shown that these universalities should be a direct consequence of a more fundamental universality, the universal geometrical shape of the nematic molecules.
