Such explanations usually take the form of articles in popular magazines and normally contain only a few references to primary sources. Never is it possible for the layperson, who becomes curious about the scientific results, to move easily to a view of the research reports and background material that form the underpinnings of the research. John Matthews, recently retired from the Geological Survey of Canada, has long been interested in solutions to these two problems. At present his answer is the production of multimedia CDs, which contain areas for both layperson and specialist as well as numerous background documents and all data associated with the project. Free distribution of science based CDs is a radical concept that few have attempted, but it is the best way to distribute scientific knowledge, especially when the presentation contains material to help the public understand the significance of the research.
Free distribution is possible in part because of the present low cost of production CDs.
Matthews is very interested in discussing presentation ideas for other large scientific projects, especially geoscience projects dealing with the Quaternary.
