The construction of Cube root: (An addition in Euclidean Geometry)

By Manoranjan Ghoshal

The Construction of Cube Root by Manoranjan Ghoshal is a thought-provoking addition to the field of classical Euclidean geometry. This work confronts one of the most historically significant unsolved problems in ancient Greek mathematics-the Delian problem, or the doubling of the cube. Long believed to be impossible with only a compass and straightedge, this problem involves constructing a line segment whose length is the cube root of two, thereby doubling the volume of a unit cube.
Ghoshal takes readers through the historical and philosophical origins of geometry, tracing its evolution from primitive cave drawings to the sophisticated rigor of classical Greek thought. The book revisits the ancient mathematical constraints that rendered certain geometric problems unsolvable under traditional rules. In particular, it focuses on the challenge of cube root construction, presenting an original geometrical theorem that he argues allows this elusive construction using classical tools.
The core of the book is the author's own contribution-a proposed theorem and geometrical method to construct the cube root of a given line segment length. Through step-by-step logical reasoning, visual aids, and application of trigonometric relationships, Ghoshal presents his case that the doubling cube problem is, contrary to historical consensus, solvable within the framework of Euclidean construction.
Designed with accessibility in mind, especially for students and educators, the book uses clear language and detailed illustrations. It offers a blend of mathematical theory, historical commentary, and pedagogical clarity, making it a unique resource for researchers, teachers, and geometry enthusiasts alike.
