A sample DOCX prepared for Pandoc → MediaWiki conversion with collapsible + / − sections

Conversion marker: Every heading beginning with Read more should be converted into a MediaWiki collapsible block. The marker itself should be removed from the published heading. The Introduction remains open by default.

Introduction

Long before geometry was formalized in the Greek mathematical tradition, the Indian Śulba Sūtras described practical geometric procedures for constructing Vedic fire altars. These texts form part of the Kalpa literature and preserve rules for measurement, transformation of shapes, proportional construction, and the creation of geometrically equivalent areas. Their purpose was ritual, yet the methods reveal a sophisticated tradition of applied mathematical reasoning.

This article is intentionally structured as a conversion sample. The introduction is kept visible, while the detailed sections below are marked for collapse. After Pandoc converts this DOCX to wiki markup, your conversion script can wrap each marked section in a collapsible container that displays a plus sign when closed and a minus sign when open.

Read more Historical and Textual Background

The term śulba means a cord or measuring rope. The Śulba Sūtras contain instructions for using cords, pegs, and measured lines to lay out ritual spaces and construct altars of prescribed shapes and areas. The best-known texts are associated with Baudhāyana, Āpastamba, Kātyāyana, and Mānava. They are generally studied as technical appendices within the larger ritual corpus.

The geometrical rules were not presented as abstract theorems in the modern style. Instead, they appeared as concise operational statements intended for practitioners. A rule might specify how to draw a perpendicular, transform a square into a rectangle, or create an altar of the same area in a different form. Commentary and practical instruction would have helped transmit the implied reasoning.

For a digital scholarly article, this background section is useful but lengthy. Making it collapsible allows a general reader to move quickly to the central idea while still giving specialists access to the full context.

Read more The Diagonal Rule

One of the most frequently discussed statements in the Baudhāyana Śulba Sūtra concerns the diagonal of a rectangle. In modern mathematical language, the rule expresses the relationship commonly written as a² + b² = c². The text describes how the diagonal produces an area equal to the combined areas produced separately by the two sides.

The importance of the passage lies not only in its resemblance to the Pythagorean relation, but also in its role within construction practice. Builders needed reliable methods for creating right angles, enlarging altar spaces, and transforming one geometrical figure into another while preserving area.

A careful historical presentation should avoid claiming that ancient authors used modern algebraic notation. Their formulation was geometric and procedural. The comparison with later mathematical expressions is interpretive and should be explained rather than imposed.

Read more Constructing Right Angles with Cords

A cord divided into proportional segments can be used to form a triangle with a right angle. The familiar 3–4–5 arrangement is one example: when the sides are measured in the ratio three, four, and five, the angle opposite the longest side is a right angle. Such cord-based constructions are practical because they require no complex instruments.

In a ritual setting, accuracy of orientation and proportion mattered. A repeatable procedure using pegs and cord made it possible to transfer geometric rules from instruction to physical construction. This is an example of mathematics embedded in material practice.

For Pravāha, this section could later include an image or animation. The collapsed state would keep the article compact, while the expanded state could display diagrams, explanations, and construction steps.

Read more Transforming Shapes While Preserving Area

The altar tradition required figures of different shapes to possess equivalent areas. This led to procedures for transforming squares into rectangles, rectangles into squares, and simpler forms into composite or symbolic shapes. The methods reveal attention to area conservation rather than visual similarity alone.

A transformation procedure typically begins with a known figure, identifies a segment to be added or removed, and then rearranges or reconstructs the figure. The process is algorithmic: the reader is told what to measure, where to place the cord, and how to complete the new boundary.

In modern educational language, these operations can be connected with geometric dissection, equivalence of areas, and constructive proof. However, the historical context should remain visible so that the original ritual and technical purposes are not reduced to modern classroom exercises.

Read more Approximation of the Square Root of Two

The diagonal of a unit square has length √2. The Śulba tradition preserves a notable approximation that can be expressed numerically as 1 + 1/3 + 1/(3×4) − 1/(3×4×34). This gives a remarkably close value for practical construction.

The rule demonstrates the need for numerical accuracy in problems involving the enlargement of a square or the construction of an equivalent area. It also shows that the tradition combined geometric procedures with fractional approximation.

A collapsible presentation is especially suitable here because the main article can state the result briefly, while the expanded section can contain the arithmetic, decimal comparison, and discussion of historical interpretation.

Read more Worked Example

Suppose a square altar has a side length of 1 unit. Its area is therefore 1 square unit. The diagonal has length √2, approximately 1.4142 units. If a construction requires this diagonal, the traditional approximation provides a practical value that can be marked using a measuring cord.

Step	Operation	Result
1	Start with a unit square	Side = 1; Area = 1
2	Add one-third	1 + 1/3 = 1.3333…
3	Add one-twelfth	1.4166…
4	Subtract 1/408	1.414215…
5	Compare with √2	Difference is very small

This table should remain inside the same collapsible section after conversion. Your converter therefore needs to group all content following the marked heading until the next heading of the same or higher level.

Read more Modern Relevance

The Śulba Sūtras are relevant to the history of mathematics, the study of knowledge systems, and contemporary mathematics education. They demonstrate that mathematical ideas can develop through architecture, ritual, measurement, and craft rather than only through formal symbolic theory.

For students, these texts provide an opportunity to compare different styles of mathematical expression. For historians, they raise questions about dating, transmission, interpretation, and the relationship between textual rules and lived practice. For digital publishers, they offer rich material that benefits from layered presentation.

Collapsible sections support this layered approach. A new reader can see the main argument immediately, while a specialist can open the detailed background, calculations, translations, or references as needed.

Read more Editorial Notes for Pandoc Conversion

Use the literal marker Read more at the beginning of a Word heading to signal that the section should be collapsible. The marker is deliberately plain ASCII so it is easy to detect in PHP, Python, JavaScript, or a Pandoc Lua filter.

Recommended conversion logic:

• Detect a heading whose text starts with Read more.

• Remove Read more from the visible heading.

• Collect the heading and all following blocks until the next heading of equal or higher level.

• Wrap the collected content in a MediaWiki mw-collapsible container.

• Add mw-collapsed when the section should be closed by default.

• Use CSS or JavaScript to display + when closed and − when open.
