The concept of relativistic length is introduced and discussed. The definition is based on a measuring procedure that directly uses a clock and light signals (analogous to the radar method), and it has as a consequence the increase of the longitudinal dimensions of fast-moving objects. Furthermore, the concept of relativistic length introduced here is in logical accord with the notion of distance utilized in relativistic electrodynamics.

The relativistic transformation equations for the pressure, volume, energy, and momentum of a gas in a closed container are discussed. Considerations are given in support of pressure noninvariance, volume dilatation, and the fact that the energy and momentum of a gas form a four-vector. It is shown that the relativistic transformation formula for temperature resulting from the Lorentz invariance requirement of the equation of state of an ideal gas coincides with the Ott formula.

Martin Strel, a Slovenian hero, swam all 3004 km of Danube in 200, and Mississippi in 2002, to become one of nominees for the sportsperson of the year award. Surprisingly, an orchestrated attack on his status as a sportsperson and on status of his achievements as sport records followed successfully. Martin did not get the award. He continued with his activities, swimming Parana, Jang Tse, and Amazonas lately, but was never mentioned in sport context again. This case is examined to (...) show how definition struggles serve to strengthen the border control between sport as such, and its internationally institutionalised realm. To make a comparison, the case of art and its definition is mentioned. Martin Strel did not endanger sport, being a false pretender on sport-status, but he endangered sport management and sport business. He was thrown out of the ?sport city?, to swim ?extra portes? and to inhabit a place where sport as ?esportes? originally belonges. (shrink)

Introduction to Sexology [Vvedenie v seksologiiu] by I. S. Kon has finally been published after having made the rounds of publishing houses for many years. This is the first Soviet publication devoted to a description and an analysis of the genesis, development, and state of a new branch of scientific knowledge about man-sexology-which affects every one of us. To be sure, General Sexual Pathology [Obshchaia seksopatologiia], a textbook for physicians edited by G. S. Vasil'chenko, which came out in 1977, has (...) an extensive introductory chapter on sexology, but it is limited to medical problems. Kon's book is an example of an interdisciplinary approach that provides an idea of the most essential components of sexology; it is thus addressed not only to the medical profession, but also to sociologists, philosophers of culture, psychologists, pedagogues, etc. The book takes into account the latest publications in this area of science.
