## Quick Overview

Capt. Litty Chacko details her extensive research into the Kerala School of Mathematics, emphasizing that their sophisticated mathematical, astronomical, and linguistic concepts—including the development of a mathematical formula for celestial movements—predate Western science and warrant greater recognition and preservation efforts, particularly through digitization.

**Key Points:**
- Litty Chacko is researching the 14th-century Kerala School of Mathematics, which developed sophisticated concepts that predate Western science.
- The school developed a mathematical formula for calculating celestial movements (planets and Moon) using trigonometry (sine/cosine series) centuries before similar concepts appeared in Europe.
- The speaker argues against the common perception that India only adopted scientific methods from the West, citing the mathematical rigor and advanced techniques used by figures like Madhava and the development of a 'Mathematical Tradition'.
- Chacko highlights the importance of preserving ancient manuscripts (like those written on palm leaves) through digitization, noting that physical documents face decay and mold.
- She mentions her own work, including designing a course on Malayalam and Manuscript Management, and successfully getting her research work recognized by UGC.
- The presentation references specific historical figures like Madhava, Jyerēkhō, Francis Bacon, and his work on 'Novum Organum' and 'The Golden Road' as context for understanding the historical scientific exchange.
- The ultimate goal of the research is to elevate the status of this indigenous knowledge system, which she suggests is often overlooked due to colonial biases.

**Context:** The video features a TEDx talk by Capt. Litty Chacko, identified as a Research Scholar on the 14th-century Kerala School of Mathematics. She addresses the audience at TEDxThiruvananthapuram ('Local Mission, Global Vision') to advocate for the recognition and preservation of the profound scientific and mathematical contributions made by this ancient Indian school, arguing that their work often surpasses or predates equivalent Western scientific advancements.

## Detailed Analysis

Capt. Litty Chacko presents her research on the Kerala School of Mathematics, an intellectual tradition flourishing in Kerala between the 14th and 16th centuries. She argues that this school developed advanced concepts, including trigonometric methods (sine/cosine series) for calculating celestial movements, centuries before similar discoveries in Europe. Chacko emphasizes that the prevailing view that India only adopted Western science is incorrect, pointing out that the Kerala school's work, especially that of Madhava, provided foundational knowledge that influenced later European thinkers like Newton and even appears in the works of Francis Bacon. She details her efforts to preserve this heritage, including designing a course on Malayalam and Manuscript Management and successfully getting her research on this tradition recognized by UGC. A critical part of her mission involves digitizing fragile palm-leaf manuscripts (palm leaf records, or 'taaliyola') to prevent their decay, noting that physical preservation is difficult. She concludes by stressing the need to recognize this indigenous scientific tradition, which she feels is often overshadowed by colonial biases, and asserts that the goal is to bring this valuable knowledge base forward for modern application and understanding.

### Introduction to Kerala School of Mathematics

- Speaker introduces herself as a scholar on the 14th-century Kerala School of Mathematics
- She acknowledges the audience and sets the stage for discussing this indigenous scientific tradition.

### Mathematical Contributions

- The school's work, particularly Madhava's, included calculating celestial movements using trigonometric series (sine/cosine) centuries before equivalent Western discoveries
- This work formed the basis for later European science.

### Preservation Efforts

- Chacko discusses the necessity of digitizing fragile palm-leaf manuscripts, showing an image of moldy manuscripts
- She mentions her work designing a course on Malayalam and Manuscript Management and receiving UGC recognition.

### Challenging Historical Narratives

- Speaker argues against the idea that India only imported science from the West, citing figures like Madhava and Bacon to show intellectual exchange
- She stresses that the scientific advancements were indigenous and often superior in certain areas.

### Conclusion and Call to Action

- The speaker concludes by hoping that the knowledge encoded in these ancient texts will continue to be studied and preserved digitally, emphasizing the cultural importance of this legacy.
