Professor Charles Friedel

Professor Charles D Meigs (1792-1869) of Philadelphia and persistent fetal circulation.

Charles Delucena Meigs was born in Bermuda in 1792. In 1799 the family moved from New Haven to Athens, Georgia, when his father was appointed president of the college there. Charles graduated in classics at the University of Georgia in 1809. His health was delicate so he then took a year off learning to ride and shoot with the Indians in Cherokee country. Next he studied medicine in Augusta, Ge...

Analysing Friedel averages and differences.

Various practical applications of the average (A) and difference (D) of Friedel opposites are described. Techniques based on the resonant-scattering contribution to Friedel differences are applied to see whether a crystal is centrosymmetric or not, and to determine the point group of the crystal. For the validation of a structural study, plots of A(obs) against A(model), and D(obs) against D(mo...

Intensity statistics of Friedel opposites.

A previous analysis of the average intensity and mean-square intensity difference of Friedel opposites, confined to the space group P1 [Flack & Shmueli (2007). Acta Cryst. A63, 257-265], is here extended to all the non-centrosymmetric space groups. The present analysis presumes purely non-centrosymmetric content of the unit cell. An important result of this study is that the average intensity a...

Charles Spence

Working at the Crossmodal Research Laboratory in Oxford, Charles Spence tries to apply the latest insights from our growing neuroscience understanding of the rules governing multisensory integration to the design of better products, packages, places, interfaces, and foods, an area that can perhaps best be captured under the title of neuroscience-inspired multisensory design.
