Georg Von Bekesy--Visualisation of Hearing.

Georg von Békésy received the Nobel Prize in 1961 for his research on the functioning of the auditory system. In psychoacoustics, Békésy both extended and perfected the lines of research begun by von Helmholtz in the 19th century. First in his native Hungary and later at Harvard, Békésy used novel and imaginative devices and methods to observe and model the functioning of the inner ear. He also...

Experiments in comparative hearing: Georg von Békésy and beyond.

Georg von Békésy was one of the first comparative auditory researchers. He not only studied basilar membrane (BM) movements in a range of mammals of widely different sizes, he also worked on the chicken basilar papilla and the frog middle ear. We show that, in mammals, at least, his data do not differ from those that could be collected using modern techniques but with the same, very loud sounds...

Hantzsche-Wendt flat manifolds

The purpose of this paper is consider some results concerning the special class of the flat manifolds (closed, Riemannian with zero sectional curvature) of dimension n with holonomy groups (Z 2) . In dimension two it is the Klein bottle and in dimension three it is a flat manifold first consider by Hantzsche and Wendt in [4]. Hence we shall call this class of the HantzscheWendt flat manifolds (...

Generalized Hantzsche - Wendt Flat Manifolds

We study the family of closed Riemannian n-manifolds with holonomy group isomorphic to Z n−1 2 , which we call generalized Hantzsche-Wendt manifolds. We prove results on their structure, compute some invariants, and find relations between them, illustrated in a graph connecting the family.
