About This Work
The Continuation of Ancient Mathematics (c. 626 CE) by Wang Xiaotong is the first Chinese text to systematically solve cubic equations arising from geometric problems. Its 20 problems involve civil engineering applications requiring cubic equation solutions, using geometric decomposition to reduce problems to standard forms—the most advanced algebraic work of its era globally.

Why This Matters
This text is part of the living archive of Chinese intellectual achievement — a tradition that produced systematic astronomical observation, mathematical innovation, medical frameworks still in clinical use, and engineering at continental scale, centuries before comparable developments in Europe.
The question "did ancient China have science?" misunderstands what science is. Science is not a single cultural tradition — it is the systematic observation of nature, the rigorous documentation of phenomena, the testing of ideas against evidence, and the building of knowledge across generations. By every one of these measures, the works in this catalogue are scientific. They used different conceptual frameworks — correlative rather than mechanistic, systemic rather than reductionist — but these frameworks produced real knowledge: accurate star catalogues, effective medical treatments, precise calendar computations, and technologies that transformed civilization.
