DESCRIPTION:Biography: Ted Nelson is an idealistic troublemaker who has be
 en promoting heretical ideas for a long time\; he coined the words "hypert
 ext" and "micropayment\," among others.  His B.A. is from Swarthmore Colle
 ge and his PhD is from Keio University in Japan.\n\n\nContrary to what you
  may have heard\, the computer world is not finished and everything has no
 t yet been invented.\n\nThe prevailing computer paradigm consists of lump 
 files with preordained metadata\, enforced hierarchy\, one-way links\, and
  paper simulation (where\,\nindeed\, a document must fit in one file).  Pa
 per simulation extends also to spreadsheet and relational database.  The W
 orld Wide Web and XML are just\nthe latest examples of this steamrolling\,
  unquestioned paradigm.\n\nIt is time to reconsider all these premises.  N
 ew foundational possibilities may yet lurk.\n\nRather than hierarchy\, I p
 ropose that the fundamental issue is representing cross-connection and int
 erpenetration\, as required by the cross-connection\nand interpenetration 
 of human thought and human life.  Note that hierarchy\, if really needed\,
  can be well represented by cross-connection but not vice\nversa.\n\nAs tw
 o entirely different instantiations of cross-connection and interpenetrati
 on\, I will present:\n\n* a deep generalization of documents: parallel doc
 ument structures with profuse connections (both links and transclusions) i
 n 3D folding space\n\n* a deep generalization of data structure: hyperthog
 onal cell constructions (orthogonal in n dimensions with no metrics and pa
 radoxical\nconnections allowed)\n\nI am not claiming these ideas are final
  either\, but they may help kick over the chessboard.
