On wine, chirality and crystallography.
As the first centennial of X-ray diffraction is inevitably drawing closer, it is tempting to reflect on the impact that this fascinating discipline has had on natural sciences and how it has changed the world we live in. Also, next year is the 160th anniversary of the fateful April afternoon when Louis Pasteur separated D- from L-tartrate crystals, an event that many science historians recogniz...

متن کاملChirality and T-duality
We consider four-dimensional N = 1 field theories realized by type IIA brane configurations of NS-branes and D4-branes, in the presence of orientifold six-planes and D6-branes. These configurations are known to present interesting effects associated to the appearance of chiral symmetries and chiral matter in the four-dimensional field theory. We center on models with one compact direction (elli...
متن کاملChirality and Protein Folding
There are several simple criteria of folding to a native state in model proteins. One of them involves crossing of a threshold value of the root mean square deviation distance away from the native state. Another checks whether all native contacts are established, i.e. whether the interacting amino acids come closer than some characteristic distance. We use Go-like models of proteins and show th...
متن کاملStegosaurus chirality
Introduction Most living things appear rather symmetrical: the external human form, for example, has a plane of mirror symmetry to good approximation. Snails, flounders, narwhals, crossbills, fiddler crabs and twining vines are members of the short but fascinating list of living things known instead to defy mirror symmetry by exhibiting exterior chirality. The study of this symmetry breaking li...
