Mesopotamian tablet YBC 7289

A tablet thought to be from southern Mesopotamia, 1800 - 1600 BC. The obverse shows calculation of a square's diagonal, by multiplying the side length by the square root of 2. The reverse is not so easily legible, but seems to treat two separate problems. This tablet is in the Yale Babylonian Collection, catalogue number YBC 7289. Illustration and animations rendered in Blender by Alistair M. Kwan (University of Auckland) from a scan by Chelsea Alene Graham (Yale University Institute for the Preservation of Cultural Heritage Digitization Lab) using an Artec Spider scanner. The animations show the tablet being rotated under static illumination, and the tablet while a light source revolves around a point in front of it.该泥板据传出自美索不达米亚南部，年代为公元前1800年至公元前1600年。其正面记载了正方形对角线的求解方法：通过将边长与√2（2的平方根）相乘得到对角线长度。反面字迹清晰度欠佳，难以清晰辨识，但似乎涉及两个独立的数学问题。该泥板现收藏于耶鲁大学巴比伦藏品馆（Yale Babylonian Collection），馆藏编号为YBC 7289。本数据集配套的插图与动画均由奥克兰大学的阿利斯泰尔·M·关（Alistair M. Kwan）使用Blender软件制作，素材来源于切尔西·阿琳·格雷厄姆（Chelsea Alene Graham）于耶鲁大学文化遗产保护数字化实验室（Yale University Institute for the Preservation of Cultural Heritage Digitization Lab）使用Artec Spider扫描仪完成的扫描件。动画内容包含两项：一是静态光照环境下的泥板旋转展示，二是光源围绕泥板前方某一点位旋转时的泥板动态效果。
