Originally published during World War II, this textbook was designed to provide a concise and practical introduction to three-dimensional geometry. It focuses on the fundamental properties of lines, planes, and solids in space, such as prisms, pyramids, cylinders, cones, and spheres. The text is notable for its clear, logical progression and its emphasis on computational problems and applicatio…
This volume offers a rapid and self-contained introductory approach to the algebraic aspects of algebraic geometry, defined by Lang as the study of systems of algebraic equations in several variables and the structures formed by their solutions. Originally published in 1958, this 1972 printing serves as an amplification of lectures based on the Weil-Zariski approach. The text covers foundationa…
This textbook offers a unique and rigorous approach to secondary school geometry, written by the renowned mathematician Serge Lang and experienced teacher Gene Murrow. Departing from the standard "two-column proof" format common in many American high schools, this text emphasizes logical reasoning and the relationship between geometry and algebra. It introduces topics such as distance, area, an…
This classic undergraduate text provides a comprehensive introduction to the fundamental concepts and methods that underpin modern mathematics. Part One explores essential tools such as the axiomatic method, set theory, the linear continuum, and the role of groups. Part Two shifts toward the philosophy and history of the field, examining major viewpoints like the Frege-Russell thesis, intuition…
A classic and authoritative reference work on the anatomy of dicotyledonous plants, widely used for taxonomic and anatomical studies in botany.
A detailed taxonomic revision of the tribe Antirrhineae, providing morphological descriptions, classification updates, and identification keys for species within the group.
