Is There a Crystal Lattice Possessing Five-Fold Symmetry?

Kepler’s Mosaics TheGermanscholar Johannes Kepler (1571–1630), who worked as a court mathematician for the Holy Roman Emperor Rudolf II in Prague, is well known especially for his astronomical discoveries.We still today admire his ability to obtain his three laws of planetary motion from data analysis of Tycho Brahe’s observations of Mars. Another outstanding discovery is Kepler’s equation desc...

Is there gender symmetry in intimate partner violence?

‘Gender symmetry’ is one of the most topical and controversial debates in the contemporary domestic violence literature. National survey data, particularly from the USA, has been utilized to support the concept of gender symmetry of violence between intimate partners. Both these statistics and the reliability of the methodologies used to obtain this data have been the focus of fierce criticism ...

Are there capacity limitations in symmetry perception?

Previous researchers have proposed that there are two types of symmetry detection: one based on crude preattentive symmetry judgments and another based on detailed scrutiny of individual parts (Barlow & Reeves, 1979; S. E. Palmer & Hemenway, 1978; Royer, 1981). Four experiments were conducted to examine capacity limits in different symmetry judgments. Observers were required to discriminate bet...

What Is Pt Symmetry?

The recently proposed complexification of Hamiltonians which keeps the spectra real (and is usually called PT symmetry) is re-interpreted as a certain natural linearalgebraic alternative to Hermiticity.
