A selection of my work on chirality is sketched in two distinct parts of this lecture. Symmetry and Chirality explains how the discrete symmetries of parity P, time reversal T, and charge conjugation C may be used to characterize the properties of chiral systems. The concepts of true chirality (time

PURPOSE: To analyze the relationships between refractive parameters as well as the relationship between fellow eyes in a normal population.METHODS: Both subjective refraction and auto-refractometry data of 500 patients were prospectively recorded. Refraction data were analyzed on three rectangular c

We report the observation of non-photochemical laser-induced nucleation (NPLIN) of sodium chlorate from its melt using nanosecond pulses of light at 1064 nm. The fraction of samples that nucleate is shown to depend linearly on the peak power density of the laser pulses. Remarkably, we observe that m

It was found, by electron-microscope observation, that D(or L)-12-hydroxystearic acid and its Li soap crystallize from a solution in various solvents in the form of a twisted fiber. The twist was left …
Like the residual late-medieval astronomy driven by Pythagorean investments and beloved by Kepler, (10) narrative embedding and its cousin ring composition revel in symmetry and enantiomorphism or mirroring, especially regarding ...
