Various results are obtained for a Friedmann-Robertson-Walker cosmology. We derive an exact equation that determines Hubble's law, clarify issues concerning the speeds of faraway objects and uncover a " tail-light angle effect " for distant luminous sources. The latter leads to a small, previously unnoticed correction to the parallax distance formula.

3D game development is an exciting activity for many students. But getting a handle on 3D game development for novices may be a daunting task. We take this opportunity to present a quick introduction to 3D game development through a few tutorials. For the next few columns a set of tutorials for a 3D first person shooter game developed by graduate and undergraduate students under the guidance of...

Social learning is thought to be a key determinant of the demand for motion pictures. This can be a double-edged sword for motion picture distributors, however, because when a film is good, social learning can enhance the effectiveness of movie advertising, but when a film is bad, it can mitigate this effectiveness. This paper analyzes an equilibrium model of the demand for films and the supply...

Studio-based teaching focuses on problem/project work and experimentation in a hands-on studio environment. Traditionally found in the arts and architecture, it is now being used in other fields such as Instructional Technology and the sciences. The first link below describes the history and rationale of studio-based teaching. Subsequent links provide information on studio teaching in a variety...
