Reviewed by A. Ben Wagner, Arts and Sciences Libraries, University at Buffalo, State University of New YorkThis video presents a clear and interesting overview of efforts to detect gravity waves, ripples through space-time caused by moving objects. Gravity waves are predicted by Einstein’s general relativity theory. The production values are excellent with particularly good simulation graphics. The film discusses in detail the plan to build the Australian International Gravitational Observatory (AIGO). In combination with other laser interferometer installations in other countries, scientists hope to finally detect the elusive gravity waves. The background and importance of this detection effort is described in easily understood terms.
The only flaw in the video is that it apparently was produced in the 1990’s. Despite an indication on the packaging of being revised in 2004, no mention was made that the AIGO has been constructed in 1999-2001 time frame. Teachers who use the video for its clear description of gravity waves should do additional research to provide their students with an updated status on research in laser interferometer gravity wave detection efforts.
This program is the first video of a 5-part physics series which is part of the larger Natural and Physical Science Series. The other titles in the physics set are: Physics 2: The Synchrotron - An Introduction; Physics 3: Blow Up – Superconductivity; Physics 4: What is Superconductivity?; and Physics 5: The Scattering of White Light.
