Cuneiform Video: Random Walks 1 – The rights and wrongs of Babylonian tablets — E8 Intelligence Research

The tablet discussed in "Random Walks 1 – The rights and wrongs of Babylonian tablets" is almost certainly **YBC 7289** (Yale Babylonian Collection), the most famous Old Babylonian mathematical clay tablet and the standard object in videos on Babylonian mathematics. It is a small, round practice tablet, roughly 8 cm across, dated to the Old Babylonian period (c. 1800–1600 BCE). If the video instead treats a different tablet, the identification below will not match — I cannot verify the specific upload, so treat this as the likely referent rather than a confirmed one. **What it records.** The tablet shows a square with its two diagonals drawn. Along one side is the sexagesimal number **30** (i.e., 30/60 = 1/2 in the scribal convention where the leading digit is a unit). Along a diagonal is written **1;24,51,10**, and beneath it **42;25,35**. - **1;24,51,10** is the Babylonian approximation of √2: 1 + 24/60 + 51/60² + 10/60³ = 1.41421296…, correct to about six decimal places (true Author: Andrew Stewart Caldin, Independent Researcher, UK.
