Thermodynamic processes are complex phenomena that can be understood as a set of successive stages. When treating processes, classical thermodynamics (and most particularly, the Gibbsian formulation, predominantly used in chemistry) only pays attention to initial and final states. However, reintroducing the notion of process is absolutely…

This chapter consists of a short history of the impact of computer technology on Christian evangelical mission research from the 1970's to the present. The trail winds through World Vision, MARC, the "World Christian Encyclopedia," "Operation World," SIL, OC International, DAWN, Global Mapping International, the AD2000 and…

The refraction problem, well-known in calculus and physics, continues to reveal new insights. This paper presents a geometric solution in which the trammel of Archimedes plays the prominent role. When properly configured, the trammel generates an ellipse and its family of normal lines. One normal line in particular intersects the boundary…

Experiments, as we all know, are especially important in science education. However, their impact on improving thinking could be even greater when applied together with the methods of inquiry-based learning (IBL). In this paper we present our observations of a high-school laboratory class where students used computers to carry out and analyse real…

Modern education technologies are destined to reflect the realities of a modern digital age. The juxtaposition of real and synthetic (computer-generated) worlds as well as a greater emphasis on visual dimension are especially important characteristics that have to be taken into account in learning and teaching. We describe the ways in which an…

This article will expand upon the techniques of Criminologist, D. Kim Rossmo, and Social Psychologist, David Canter for determining a serial criminal's base of operations. The basic framework for our investigation is that of Rossmo, but uses a different criterion for analysing the relationship of points within the hunting area defined by the crime…

This paper is based on three beliefs. First, technology can engage and challenge students' thinking. Second, technology can assist students in creating quality work. Finally, computer-generated student-work can be used as educational tools in productive ways that other student-work cannot. This article suggests new ways to use old technologies to…

The ability to use computer-based technology is an essential skill set for students majoring in chemistry. This exercise details the introduction of appropriate uses for this technology in the organic chemistry series. The incorporation of chemically appropriate online resources (module 1), scientific databases (module 2), and the use of a…

There is considerable interest in electric and hybrid cars because of environmental and climate change concerns, tougher fuel efficiency standards, and increasing dependence on imported oil. In this article, the author describes the history of electric vehicles in the automotive world and discusses the components of a hybrid electric vehicle.…

A major strand of science and technology studies in recent decades has related to the social construction of technology (SCOT) movement, whose adherents maintain that technological systems are determined just as much by social forces as by technological ones. Taking this SCOT notion as a starting point, and putting a focus on the user, this paper…

Education is an active process in which instructors apply various devices to make the material to be taught more suitable for students' perception. As the capabilities of available devices improve, so should the methods of teaching make the best use of them. No tool can ever replace an instructor, but tools can enhance the efficiency of…

To improve quality of science education, the author suggests use of entertaining and exciting technique of animation for better understanding of scientific principles. Latest technologies are being used with more vigour to spread venomous superstitions. Better understanding of science may help students to better their scientific temper. Keeping…

According to the Merriam-Webster dictionary, a planimeter is "an instrument for measuring the area of a plane figure by tracing its boundary line". Even without knowing how a planimeter works, it is clear from the definition that the idea behind it is that one can compute the area of a figure just by "walking" on the boundary. For someone who has…

Shawn Brixey's "Altimira" is a decidedly strange work of art--so strange that he has not, to date, put it on public display. He turns on a device, housed in a basketball-size glass chamber, and it converts rapidly pulsating radio signals emanating from pulsars--collapsed stars that spin violently, sweeping their poles like lighthouses…

It is the universal cry of parents the world over, driven mad by the persistent sight of their children investing hours and hours in mastering the many layers of a video game. To the parent, video games are the enemy, the nemesis of homework and learning. But the child sees something of value, something engaging enough to fill a weekend, to the…
