in our description of nature. Especially in physics, it had been assumed since the days of Isaac Newton that space and time were symmetric, i.e. that a space-time inversion of a closed physical system would not change its intrinsic interactions and dynamics. It was the discovery of the parity violation, first theoretically by Lee and Yang [@Lee1956] and immediately afterwards by the experiment of Wu and co-workers [@Wu1957] that put an end to this presumed certainty.\
From the point of view of a chemist, and especially a biochemist and molecular biologist, the preponderance of a certain spatial direction or configuration is a fact known since the middle of the 19th century. At that time, chiral molecules were discovered, i.e. molecules that occur in two mirror image structures. For most chiral species, only one of these so-called enantiomers was found in nature, a circumstance known as biological homochirality.\
After the discovery of parity violation, hypotheses to link this fundamental asymmetry to biological homochirality quickly arose. These hypotheses can be categorized into two main lines of thought: On the one hand, parity violation introduces a small difference in the energy levels of the two enantiomers [@Quack2002]. On the other hand, the asymmetry
