Madeleine L'emgle is a wonderful author of science fiction/fantasy for children. I think her first book was "A Wrinkle in Time" in which she describes the space-time continuum as being like a piece of fabric, which can be wrinkled. By jumping from the ridge of one wrinkle to the ridge of the next wrinkle, you can travel forward or backward in time. This she calls 'tessering" and the wrinkle is called a "Tesseract" . hilary Hans van der Genugten wrote: > > -----Oorspronkelijk bericht----- > Van: Hilary Blue <[log in to unmask]> > Aan: [log in to unmask] <[log in to unmask]> > Datum: dinsdag 24 augustus 1999 15:52 > Onderwerp: Re: TESSERACT > > >> but to the fact that they were stimulated to say > something,.
