What I learned today

  Europe’s Megalithic Masons Stone, Skill, Mobility, and the Making of Monumental Landscapes TOC Introduction — The Wrong Question: “Who Built the Megaliths?” The problem with treating “megalithic” as a people Monument type ≠ population Monument similarity ≠ common ethnicity Stone transport ≠ migration Shared construction knowledge ≠ demographic replacement Why archaeology over-observes stone and under-observes labor, routes, boats, timber, rope, food supply, and technical instruction The monument as surviving endpoint of a largely vanished production system The central question: how did European communities acquire, reproduce, and transmit large-stone engineering? Part I — Before the Mason 1. Monumentality Before Monumental Stone Recurrent gathering before permanent construction Territorial memory without villages Burial grounds, ancestor places, route markers, and aggregation nodes Cerny and Passy as a useful pre-megalithic comparison Monument ≠ permanent settlement Monument ≠ ag...

vectors and tensors  the dependency chain that makes vectors and tensors necessary, rather than around historical chronology.
