Physical activity in the form of consistently opting for stair use instead of elevator use can have important health benefits. The article discusses a study assessing whether increasing the attractiveness and accessibility of a stairwell had an impact on stair use among students and employees of Maastricht University, the Netherlands. The…

It was obvious long ago that for mechanical behavior a gravitational field and an accelerating frame of reference are equivalent. Or in other words: it is impossible to decide whether you are in an accelerating elevator or in a closed room on a planet with a different value of "g". In the first section of this article I will describe a simple…

In this paper, we present a teaching proposal used in an Introductory Physics course to civil engineering students from Porto's Engineering Institute/Instituto Superior de Engenharia do Porto (ISEP). The proposal was born from the need to change students' perception and motivation for learning physics. It consists in the use of an integrator…

This study aims to find out the extent to which students attending the English Language Teaching Programme (ELT) at Ondokuz Mayis University are aware of the major spelling, vocabulary, and pronunciation differences between American and British English which constitute the most commonly used varieties of English. To this end, 42 randomly selected…

This document, approved by the Rehabilitation Engineering & Assistive Technology Society of North America (RESNA) Board of Directors in September 2005, shares typical clinical applications and provides evidence from the literature supporting the use of seat-elevating devices for wheelchair users. Wheelchair mobility is often only considered from…

The present study focuses on the way thought experiments (TEs) can be used as didactical tools in teaching physics to upper secondary-level students. A qualitative study was designed to investigate to what extent the TEs called "Einstein's elevator" and "Einstein's train" can function as tools in teaching basic concepts of the…

The drop towers of yesteryear were used to make lead shot for muskets, as described in "The Physics Teacher" in April 2012. However, modern drop towers are essentially elevators designed so that the cable can "break" on demand, creating an environment with microgravity for a short period of time, currently up to nine seconds at…

Unusual fears have long been recognized as common in autism, but little research exists. In our sample of 1033 children with autism, unusual fears were reported by parents of 421 (41%) of the children, representing 92 different fears. Many additional children had common childhood fears (e.g., dogs, bugs, and the dark). More than half of children…

Baltimore City Community College (BCCC) leveraged heightened student interest and enrollment in the sciences and allied health with Maryland's world-leading biotechnology industry to build a community college life sciences learning and research center right on the University of Maryland, Baltimore's downtown BioPark campus. The BCCC Life Sciences…

Objective: The authors evaluated whether motivational signage influenced rates of stair use relative to elevator use on a college campus. Participants: In March and April 2004, the authors observed students, faculty, staff, and any visitors accessing a college campus building. Methods: During Phase I, the authors monitored ascending stair and…

Publicists often advise authors to be ready at a moment's notice to give the "elevator speech" about their books to anybody and everybody who will listen. Dr. Melissa V. Harris-Perry, the Tulane University professor, MSNBC commentator and pundit, is no stranger to media interviews. When she talked to Diverse weeks before the book was due out, she…

The purpose of this study was to reduce the negative effects that self-perceived levels of test anxiety have on third-grade students. The participants in this study consisted of 177 third-grade students at two Midwestern public elementary schools. Students at one school were taught relaxation techniques, while students at the second school served…

This article describes how Beverly and Martin Ryfa, working with an architect who specializes in accessible design, were able to build a house that is handicap accessible for their 9-year-old daughter, Danielle, who suffered an intraventricular hemorrhage when she was three days old. The article describes the features of their house that make…

In 1907, Einstein described a "Gedankenexperiment" in which he showed that free fall in a gravitational field is indistinguishable from a body at rest in an elevator accelerated upwards in zero gravity. This paper describes an apparatus, which is simple to make and simple to operate, that acts as an observable footnote to Einstein's example. It…

Describes construction of an exhibit which uses the acceleration of an elevator to distinguish mass and weight. (CP)
