| The purpose, of this section of our web site, is to present a number of things which are inappropriate elsewhere, albeit necessary to make available. Facts are just that, technical scientific information that needs to be presented to those with a desire for details. Reflections are a bit more than frequently asked questions (FAQ) as it includes material of historic interest or thinking (original or otherwise) about various relevant topics. Methods are details and information relating to either the official methods of some agency or organization or just commonly accepted but little understood procedures.
We dwell in a litigious age and whilst every effort is made to be accurate, correct and polite, perfection is a goal and not always a reality. Therefore, the following exculpatory statement is necessary: Disclaimer & Limit of Liability
