Nalanda University Lecture Traces India's Mathematical Legacy From Brahmagupta to Ramanujan
Nalanda University in Rajgir, Bihar, hosted a lecture exploring India's mathematical heritage, connecting the work of ancient scholars with developments in modern mathematics. The concluding lecture of the university's Nalanda Spirit foundational course was delivered by Professor Ashish Gupta under the title “From Bhavana to Infinite”. It examined how mathematical ideas developed across centuries and continue to inform contemporary research.
The lecture highlighted the contributions of Brahmagupta, Bhaskara II and Srinivasa Ramanujan, while also discussing the mathematical work of Carl Friedrich Gauss and Manjul Bhargava. The event connected the history of mathematics with Nalanda University's broader emphasis on intellectual inquiry, knowledge exchange and interdisciplinary learning.

Brahmagupta: Contributions to Algebra and Number Systems
Brahmagupta, who lived during the seventh century, was an influential Indian mathematician and astronomer. His work Brahmasphutasiddhanta, composed in 628 CE, addressed arithmetic, algebra and astronomy.
One of the ideas associated with Brahmagupta is the Composition Law, which describes how solutions to certain quadratic equations can be combined to generate further solutions. Such relationships are important in the study of number theory and algebra.
His work also contains systematic rules for calculations involving zero and negative numbers. These developments formed part of the long historical evolution of arithmetic and algebraic methods across different mathematical traditions.
Bhaskara II and the Chakravala Method
Bhaskara II, also known as Bhaskaracharya, was a prominent Indian mathematician and astronomer of the twelfth century. His mathematical writings explored arithmetic, algebra, geometry and astronomical calculations.
The Chakravala method, associated with Indian mathematical traditions and discussed in connection with Bhaskara II's work, is an iterative technique for solving certain indeterminate equations. It is particularly associated with equations involving integer solutions and is an important example of sophisticated premodern algebraic reasoning.
The method illustrates how mathematicians developed systematic procedures to address problems that could require repeated calculations rather than a single straightforward operation.
Srinivasa Ramanujan and the Rogers–Ramanujan Identities
Srinivasa Ramanujan, born in 1887, became one of India's most widely recognised mathematicians. His work contributed to number theory, infinite series, continued fractions and mathematical identities.
The Rogers–Ramanujan identities are important relationships involving infinite series and infinite products. They have applications in areas of mathematics including partitions and combinatorial theory. Their continuing study demonstrates how mathematical results developed in one historical period can become relevant to later research.
Ramanujan's career also illustrates the importance of independent mathematical exploration and international scholarly collaboration. His work with British mathematician G. H. Hardy helped bring his discoveries to wider attention within the international mathematical community.
From Historical Mathematics to Modern Research
The lecture also referred to Carl Friedrich Gauss and Manjul Bhargava to show how mathematical structures and ideas continue to evolve. Gauss was a major figure in number theory, while Bhargava is known for contributions to modern number theory and related mathematical fields.
By placing historical ideas alongside modern research, the lecture emphasised that mathematics develops through the continued investigation, reinterpretation and extension of earlier results. Studying historical methods can help students understand the evolution of mathematical reasoning, although modern theories must be evaluated using contemporary mathematical standards.
Nalanda University and the Nalanda Spirit Course
Nalanda University's Nalanda Spirit foundational course explores the intellectual and institutional legacy of ancient Nalanda through historical evidence and interdisciplinary study. Its stated approach connects India's philosophical, cultural and intellectual traditions with contemporary questions.
The university's programme is not limited to mathematics. Its wider academic approach encourages students from different backgrounds to examine the development of ideas, their historical connections and their relevance today.
At the concluding lecture, Vice-Chancellor Professor Sachin Chaturvedi also highlighted the importance of reviving regional mathematical traditions, including those associated with Kerala and Agra. Preserving historical records and encouraging research into regional knowledge traditions can broaden understanding of India's mathematical history.
Nalanda University Highlights IIRS–ISRO Learning Opportunity
The event also highlighted Nalanda University's designation as a nodal centre for the Indian Institute of Remote Sensing (IIRS)–ISRO Distance Learning Programme. Professor Deepak Kumar, the university's IIRS nodal coordinator, outlined the initiative and encouraged students to explore the available courses.
Remote sensing uses information collected by sensors, often mounted on satellites or aircraft, to study the Earth's surface and environment. Its applications include land-use mapping, agriculture, water-resource assessment, disaster management and environmental monitoring.
Students interested in this field should check the official IIRS learning platform for current course availability, eligibility, registration procedures and completion requirements.
