About This Work
Master Sun's Mathematical Manual (3rd–5th centuries CE) contains the earliest known statement of the Chinese Remainder Theorem. Its 26th problem—finding a number leaving specified remainders when divided by 3, 5, and 7—presents the first modular arithmetic solution in world mathematics. It also covers fractions, square roots, and practical administrative computation.

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.
