A History of Folding in Mathematics Mathematizing the Margins【電子書籍】[ Michael Friedman ]

＜p＞While it is well known that the Delian problems are impossible to solve with a straightedge and compass ? for example, it is impossible to construct a segment whose length is cube root of 2 with these instruments ? the discovery of the Italian mathematician Margherita Beloch Piazzolla in 1934 that one can in fact construct a segment of length cube root of 2 with a single paper fold was completely ignored (till the end of the 1980s). This comes as no surprise, since with few exceptions paper folding was seldom considered as a mathematical practice, let alone as a mathematical procedure of inference or proof that could prompt novel mathematical discoveries. A few questions immediately arise: Why did paper folding become a non-instrument? What caused the marginalisation of this technique? And how was the mathematical knowledge, which was nevertheless transmitted and prompted by paper folding, later treated and conceptualised?＜/p＞ ＜p＞Aiming to answer these questions, this volume provide．．．楽天市場のショップで商品詳細の続きを見る
