Webarchitecture aﬀects h, and (3) elucidate the transition from necessarily non-uniaxial chiral molecules to an essentially uniaxial macroscopic free energy. Since his zero for achiral molecules, it is natural to expect that hwill be proportional to some parameter measuring the “degree of chiral-ity” of constituent molecules. A chiral molecule is a type of molecule that has a non-superposable mirror image. The feature that is most often the cause of chirality in molecules is the presence of an asymmetric carbon atom. The term "chiral" in general is used to describe the object that is non-superposable on its mirror image. fits breeches blackWebIn art and architecture, chirality is an often seen feature in towers, columns, and staircases, to name a few.
