Synergetics coordinates is Clifford Nelson's attempt to describe, from another mathematical point of view, Buckminster Fuller's '60 degree coordinate system' for understanding nature. Synergetics is the word Fuller used to label his approach to mathematics.〔 Clifford Nelson, (Buckminster Fuller Notebooks ) 〕 ==Geometric definition== A system of synergetics coordinates uses only one type of simplex (triangle, tetrahedron, pentachoron, ..., n-simplex) as space units, and in fact uses a regular simplex, rather like Cartesian coordinates use hypercubes (square, cube, tesseract, ..., n-cube.) The n Synergetics coordinates axes are perpendicular to the n defining geometric objects that define a regular simplex; 2 end points for line segments, 3 lines for triangles, 4 planes for tetrahedrons etc.. The angles between the directions of the coordinate axes are Arc Cosine (-1/(n-1)). The coordinates can be positive or negative or zero and so can their sum. The sum of the n coordinates is the edge length of the regular simplex defined by moving the n geometric objects in increments of the height of the n-1 dimensional regular simplex that has an edge length of one. If the sum of the n coordinates is negative the triangle (n = 3) or tetrahedron (n = 4) is upside down and inside out. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Synergetics coordinates」の詳細全文を読む スポンサード リンク
