In this article we propose an activity aimed at introductory students to help them understand the Stefan-Boltzmann and Wien's displacement laws. It only requires simple materials that are available at any school: an incandescent lamp, a variable dc energy supply, and a computer to run an interactive simulation of the blackbody spectrum.…

A great start for the semester, this pinwheel project provides a good dose of art history, and a variety of media and techniques. It also teaches students how to clean up and store things properly. Five artists are introduced, each with a different art medium and technique. In this activity, students are expected to: (1) study works by five famous…

The Formal Elements Art Therapy Scale (FEATS) is a measurement system for applying numbers to global variables in two-dimensional art (drawing and painting). While it was originally developed for use with the single-picture assessment ("Draw a person picking an apple from a tree" [PPAT]), researchers can also apply many of the 14 scales of the…

Meaningful visual experience requires computations that identify objects as the same persisting individuals over time, motion, occlusion, and featural change. This article explores these computations in the tunnel effect: When an object moves behind an occluder, and then an object later emerges following a consistent trajectory, observers…

CHROMACODE is a conceptual tool that uses systematic, logical, and visual processes for organizing and analyzing qualitative research findings for the researcher with relatively low technical knowledge of data analysis. It can best be described as a visual conceptual scheme with coding based on a color-dependent procedure. Color provides a sense…

This hardware review describes such innovative features of the Texas Instrument Portable Professional Computer as integrated color screen and option slots permitting customization as well as the physical unit (inside and out), its mass storage flexibility, and sturdiness. A comparison with the IBM PC Portable is included. (MBR)

Discusses print quality, speed, print modes, buffers, and character sets of daisy-wheel and dot-matrix printers; briefly reviews features needed to print graphics and color; and presents a chart listing over 30 typical daisy-wheel and dot-matrix printers for comparison of features and price. (MBR)

Presents a review of the literature dealing with the theory of the naming of colors. A comparison is made between the names of colors in Italian and Dutch, discussing the differences between languages in terms of the influence of the sociocultural context. (61 references) (CFM)
