"The most important discoveries are often the most unexpected - not a mere extrapolation from what we know currently, but something completely different. The reason is that nature is far more inventive, subtle and elegant than humans are. So in a way it's foolish to attempt to anticipate what the most significant findings...might be in the next few decades" Carl Sagan "Billions and Billions" (1998) p. 50 ----------------------------------------------- FURTHER REFERENCES GO - "search perceptions" - in SEARCH-ENGINE file-ID www.perceptions.couk.com/discover.txt
