Ada K. Dietz (June 16, 1882 - May 13, 1950) was an American weaver best known for her 1949 monograph ''Algebraic Expressions in Handwoven Textiles'', which defines a novel method for generating weaving patterns based on algebraic patterns. Her method employs the expansion of multivariate polynomials to devise a weaving scheme. Dietz' work is still well-regarded today, by both weavers and mathematicians. Along with the references listed below, Griswold (2001) cites several additional articles on her work. ==History== Ada Dietz developed her algebraic method in 1946 while living in Long Beach, California. An avid weaver, Dietz drew upon her experience as a former math teacher to devise a threading pattern based on a cubic binomial expansion. She describes her idea as follows: :"Taking the cube of a binomial :"In this case, ''x'' equaled the first and second harnesses, and ''y'' equaled the third and fourth harnesses. Then it was simply a matter of expanding the cube of the binomial and substituting the values of ''x'' and ''y'' to write the threading draft." (Dietz, 1949) A piece based on the formula (''a'' + ''b'' + ''c'' + ''d'' + ''e'' + ''f'')2, submitted to the Little Loomhouse Country Fair in Louisville, Kentucky received such a positive response, which prompted a collaboration between Dietz and Little Loomhouse's founder, Lou Tate. The fruits of the collaboration included the booklet ''Algebraic Expressions in Handwoven Textiles'' and a traveling exhibit which continued throughout the 1950s. 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「Ada Dietz」の詳細全文を読む スポンサード リンク
