Chirality, meaning right- or left-handedness, pervades much of modern science, from the physics of elementary particles, through organic stereochemistry, to the structure and behavior of the molecules of life, with much else besides (nonlinear optics, materials, nanoscience, electrical engineering, pharmaceuticals, astrobiology, origin of life, etc.). The word 'chirality' was introduced into science by Lord Kelvin in 1904. This talk will survey the fundamental physical chemistry aspects of chirality that define and govern many of its manifestations in molecular and biomolecular science. Symmetry properties, especially the time-even pseudoscalar aspect of the associated interactions and observables, will be emphasized.
