IN AN Istanbul manuscript collection of scientific and philosophical articles, there are several monographs by Thabit ibn Qurra, ninth-century mathematician and scientist. One of them is on the "Socratic proof" of the Pythagorean theorem.' This article is a letter written by the author to a friend who was somewhat disappointed with the "Socratic proof" of the Pythagorean theorem, as this proof deals with a special case only, namely, that of an isosceles right triangle, and he wished Thabit to… 

Foreword

The reluctant decision was made to leave the era of George Sarton's own editorship to some future time, and to concentrate on a cumulative index covering the three decades and thirty volumes of Isis that stretch from 1953 to 1982.

Geometrical Figures and Generality in Ancient China and Beyond: Liu Hui and Zhao Shuang, Plato and Thabit ibn Qurra

Argument This paper argues that there was a shift in China in the nature, and use, of geometrical figures between around the beginning of the Common Era and the third century. Moreover, I suggest

"square Trisection". Dissection of a Square in Three Congruent Partitions

An historical overview of the square trisection problem starting with its origins in the third century is presented and a conjecture of optimality of the proposed solution is concluded.

Piano-Hinged Dissections: Now Let's Fold!

A new type of hinging is explored for geometric dissections of two-dimensional figures, which includes the use of polygon structure, the conversion from twisted-hinged dissections, the folding analogue of a P-slide, and the using of tessellations.

The heptagon to the square, and other wild twists

ConclusionWe have identified some surprising new twist-hinged dissections, using special-purpose techniques. Further examples and adaptations of these techniques appear in a companion paper [17]. All
