Changing the future: Coder Kyra Anand is breaking the computer barrier for many girls

ti amidst floods that claimed the lives of three of his grandparents, his birth was considered unlucky by most people, except his mother. “She named me Yogabalaji since she considered me lucky (yoga), and I was born during the Chithirai festival - dedicated to Lord Balaji,” smiles Yogabalaji in an interview with Global Indian. From a village school that lacked basic facilities like a lab, playground and even toilets, he aspired higher.

“Growing up, I always wondered about climate change and the environment. A lot of my questions were answered when I began college. I began researching some more, and realised that emission of Co2, increase in usage of vehicles, and production of cement were some of the major contributing factors to climate change,” says the young climate activist, who believes in the adage - be the change you want to see.

He spent more than two years researching the replacement of cement in concrete. This was submitted to the American Concrete Institute, a leading civil engineering body. His project received the second prize at the ACI students’ competition. That apart, this climate activist has also been working at the grassroot level to spread awareness about zero carbon and low carbon technologies. “I also speak to students and village folk to spread awareness about environmental issues and encourage them to adopt cleaner ways of life,” says the student at Coimbatore-based PSG Institute of Technology. He also visits schools to hold workshops and has been conducting webinars through the Covid-19 pandemic as well.

A tree planting crusader

So far, Yogabalaji has planted more than 10,000 trees and visited more than 50 schools to talk about climate change and sustainable development practices. He also works with leading educational organisations such as Agaram, SEEEDS, and Hope3 Foundation. Some of his research includes social development projects under the TN government.

“The highlight for me was when former President, the late Dr APJ Abdul Kalam invited me and complimented me with books and chocolates for the work I’d been doing. It motivated me to continue carrying out social activities,” beams Yogabalaji, who also works in the spheres of senior citizen welfare and road safety awareness.

In 2020, he received a call from the MHRD to work with them in the Samadhan challenge. “I was the only student to be selected for this. My responsibility included creating awareness in rural India, providing masks, sanitisers and other essentials, analysing problem statements, and providing digital solutions,” says the civil engineering student, who spent days sleeping for an average three hours as he juggled various tasks.

Being the change

Given his background and the fact that his community is majorly affected by the lack of education and environment change, Yogabalaji is determined to change things in the future. “In 1995, my village faced devastating drought, and people suffered from diarrhea. In fact, my elder sister too passed away due to illness at that time. A few years later, around when I was born, my village battled floods during which my grandparents died,” he says, adding, “I now want to start an NGO and work in the areas of education and environment. I want to help identify deserving students and provide them quality education by way of mentorship, guidance and involving them in development activities. In the areas of environment, I want to work on CSR policies with leading companies.”

As he marches on with this vision, Yogabalaji wants to be a leader who can affect change and social development. Penning poetry on feminism, environment and singing songs to spread awareness, his oeuvre is about creating better lives. And he is well on his way to doing that.

India’s legacy at the International Mathematical Olympiad

This year teams from the USA, China, and South Korea finished as the top three winners. India secured a total score of 167, just one mark behind South Korea, which finished third. A total of 609 students (528 male, and 81 female) participated at the IMO 2024, representing 108 countries.

The fourth rank in 2024, marks the best performance by India at the IMO since the country’s debut in 1989, both in terms of the number of gold medals won and the rank achieved. Previously, India's highest rank was seventh, which was achieved in both IMO 1998 and 2001.

Since 2019 (except for 2020 when the team couldn't participate), Team India has secured at least one gold medal every year, accumulating a total of nine gold medals over this period.

Indian team member Aditya's performance also earned him an overall ranking of fifth, marking the best performance by an individual from an Indian team ever.

Talking about his tryst with mathematics Aditya shared with the PM, “I had keen interest in math since early childhood. My teacher in standard six played a significant role in developing my interest in the subject.” While Siddharth his school mate added “I was in same class as Aditya and even I had interest in math since childhood, and the same teacher helped us hone our skills in standard six.”

Indian contingent in the UK

Before heading for the competition, the Indian team trained at the IMO Training Camp held at Chennai Mathematical Institute (CMI). In UK the young math wizards were accompanied by mentors like professor Krishnan Sivasubramanian of IIT Bombay, and former IMO medallists Rijul Saini of Homi Bhabha Centre for Science Education (HBSCE), and Rohan Goyal; currently a Ph D student at MIT, USA, among others.

Apart from participating in the competition the high schoolers were thrilled to meet people from different countries and to explore the city of Bath and Oxford. “We met lots of students from other countries and it was very nice to interact and connect with them. We also got an opportunity to meet several famous mathematicians. We loved exploring the city of Bath and were even taken to Oxford University. It was a very good experience,” Siddharth shared in Mann Ki Baat.

Making friendship with mathematics

Answering Modi’s question on how to build a friendship with mathematics, Rushil remarked, “When we learn addition as kids, we are taught to carry-forward, but we are not taught why carry-forward is important. Similarly, when we learn about compound interest, we never ask where the formula for compound interest comes from. I think that maths is actually an art of thinking and problem-solving. I believe that while practising maths, if we question why we have to do things the way we are taught, and understand the reasons – it would increase our interest in the subject, as students get scared of things which they cannot understand.

Rushil looks at mathematics as a very logical subject. “It allows creative thinking, enabling students to come up with out-of-the-box solutions - a quality that comes in handy in the Maths Olympiad.”

Preparation, selection and family’s support

The students participating in the Mathematical Olympiad get four-and-a-half hours to solve a paper consisting of three long math problems. Although, on average, there is one-and-a-half hours to solve each problem, they are complex and the preparation to answer them correctly takes days.

“During the preparation phase, it takes up to three days to work on one such problem,” Arjun shared. Talking about the preparation process, he informed the PM that the team prepared for IMO by looking up problems on the internet and practising previous years’ papers. “As we worked on the problems, our speed and proficiency increased - most significantly, our problem-solving ability improved, helping us not just in mathematics but in other walks of life.”

Kanav from Greater Noida, who is now in class 11, shared that he started preparing for the Olympiad when he was in standard seven. Both he and Arjun credited their families for support. “I feel that when a member of a family is preparing for such a competition, it’s not just the struggle of the participant but the entire family,” remarked Arjun.

Selection for the finalists from India for the International Mathematical Olympiad is conducted in five stages by the Homi Bhabha Centre for Science Education (HBCSE). Kanav shared that although he came very close to qualifying last year, he could not finally make it and was dejected. However, he felt motivated by his parents' words – ‘that it’s the journey that is important, not the destination’. “If we love the subject and enjoy the journey, we will ultimately get success,” was the advice of his parents that kept him motivated.

Strategy of success

It was Anando’s second IMO experience, and he loved both. “Math requires patience,” he believes. “In the way we are taught maths, we are given a formula to memorise. Whether one truly understands the formula is often overlooked. Just solving problems using the formula is emphasised, so that with practice, the formula gets ingrained in memory. But what would happen if one forgets the formula in the exam? Hence students should try to understand the formula first,” was his advice to students.
