"The time will come when diligent research over long periods will bring to light things that are now hidden . . . [K]nowledge will be unfolded only through long successive ages. There will come a time when our descendants will be amazed that we did not know things that are so plain to them . . . Many discoveries are reserved for ages still to come, when the memory of us will be effaced. Our universe is a sorry little affair unless it has in it something for every age to investigate . . .Nature does not reveal her mysteries once and for all."
-- Seneca [4 B.C.-65 A.D.]
