The first three pages were the standard text he knew by heart: clamping a rubber specimen between metal plates, compressing it by 25%, exposing it to -40°C for 22 hours, then measuring the permanent deformation. But page four was different. A hand-drawn diagram overlaid the original. A second set of pressure plates, not made of steel, but of a honeycombed alloy. And in the margin, a single line of text:
