Madhava of Sangamagrama is credited with developing a series expansion for the sine function, which is considered a precursor to the modern calculus. However, there is a debate over whether he actually discovered the calculus before Isaac Newton and Gottfried Wilhelm Leibniz.

The main point of contention in the debate over the discovery of the calculus was who first published their work on the subject. Newton and Leibniz both published their findings around the same time, but there is debate over who actually developed the calculus first.

Andrew Wiles, a British mathematician, is credited with proving Fermat's Last Theorem in 1994. However, there was a controversy surrounding his proof, as some mathematicians questioned the validity of his methods.

The main point of contention in the debate over the proof of Fermat's Last Theorem was whether Wiles' proof was actually correct. Some mathematicians argued that there were errors in his proof, while others defended its validity.

Bhaskara II is credited with writing the Lilavati, a treatise on mathematics that covers topics such as arithmetic, algebra, geometry, and astronomy. However, there is a debate over whether he was the sole author of the Lilavati, as some scholars believe that other mathematicians may have contributed to its content.

The main point of contention in the debate over the authorship of the Lilavati was whether Bhaskara II was the sole author of the text. Some scholars believe that other mathematicians may have contributed to its content, while others argue that Bhaskara II was the primary author.

Varahamihira was an Indian mathematician and astronomer who is known for his work on astrology. He wrote several texts on the subject, including the Brihat Samhita, which is considered one of the most important works on astrology in Indian history. However, there is a debate over the use of mathematics in astrology, as some mathematicians believe that it is not a valid scientific practice.

The main point of contention in the debate over the use of mathematics in astrology is whether astrology is a valid scientific practice. Some mathematicians believe that astrology is not a science, as it is not based on empirical evidence. Others argue that astrology can be a valid scientific practice, as it is based on mathematical calculations and observations of the planets.

C. Rajagopalachari was an Indian politician and mathematician who served as the first Chief Minister of Madras State. He was involved in a controversy over the teaching of mathematics in schools, as he believed that the traditional method of teaching mathematics was too abstract and did not focus enough on practical applications. He advocated for a more hands-on approach to teaching mathematics, which would make it more relevant to students' lives.

The main point of contention in the debate over the teaching of mathematics in schools was whether the traditional method of teaching mathematics was too abstract. Some educators believed that the traditional method was too focused on rote memorization and did not allow students to develop a deep understanding of mathematical concepts. Others argued that the traditional method was necessary to provide students with a solid foundation in mathematics.

Raj Reddy is an Indian computer scientist and roboticist who is known for his work on artificial intelligence and natural language processing. He was involved in a controversy over the use of computers in mathematics, as he believed that computers could be used to solve mathematical problems that were previously thought to be impossible. He argued that computers could be used to automate mathematical proofs and to discover new mathematical theorems.

The main point of contention in the debate over the use of computers in mathematics was whether computers could be used to solve mathematical problems that were previously thought to be impossible. Some mathematicians believed that computers could be used to solve these problems, while others argued that computers were not capable of such feats.

Vandana Shiva is an Indian environmental activist and author who is known for her work on the impact of modern agriculture on the environment. She has been involved in a controversy over the role of mathematics in society, as she believes that mathematics is often used to justify the exploitation of nature. She argues that mathematics should be used to promote sustainability and to protect the environment.

The main point of contention in the debate over the role of mathematics in society was whether mathematics is often used to justify the exploitation of nature. Some people believe that mathematics is a neutral tool that can be used for good or for evil, while others argue that mathematics is inherently biased towards the exploitation of nature.

Savitribai Phule was an Indian social reformer and educator who is known for her work on women's rights and education. She was involved in a controversy over the teaching of mathematics to girls, as she believed that girls should have the same opportunities as boys to learn mathematics. She opened a school for girls in Pune, India, where she taught mathematics and other subjects.

The main point of contention in the debate over the teaching of mathematics to girls was whether girls should have the same opportunities as boys to learn mathematics. Some people believed that girls should have the same opportunities as boys, while others argued that mathematics was not a suitable subject for girls to learn.
