K S Krishnan: The Unsung Hero of Indian Physics

K S Krishnan The Unsung Hero of Indian Physics

“True science thrives not in isolation but in the exchange of ideas.” — K S Krishnan

Did you know that the great Indian physicist Kariamanickam Srinivasa Krishnan (K S Krishnan) played a pivotal role in discovering the Raman Effect but never received the same level of recognition as his mentor, C. V. Raman? K S Krishnan was a brilliant scientist whose contributions to physics transformed our understanding of matter. From collaborating on groundbreaking discoveries to building institutions, his life and legacy remain an inspiration for modern science.

Early Life and Education

Born on December 4, 1898, in Watrap, a small village in Tamil Nadu, K S Krishnan grew up in a family that valued education deeply. His father was a school teacher who instilled a love for learning in young Krishnan. From an early age, Krishnan showed an exceptional aptitude for mathematics and physics.

Krishnan pursued his higher studies at Madras Christian College, where he earned a degree in physics. He stood out as a student not just for his academic brilliance but also for his curiosity and ability to think critically. After graduation, he joined the Indian Association for the Cultivation of Science (IACS) in Calcutta, where he came under the mentorship of the legendary physicist C. V. Raman.

The Pivotal Moment: Discovering the Raman Effect

One of the most defining moments in Krishnan’s career was his collaboration with C. V. Raman on the discovery of the Raman Effect. While Raman was the driving force behind the research, Krishnan played a crucial role in conducting experiments and analyzing results. Together, they demonstrated how light scatters when it passes through a medium, leading to a discovery that won Raman the Nobel Prize in Physics in 1930.

However, the recognition for this groundbreaking work largely overshadowed Krishnan’s contributions. Despite his critical role in the research, Krishnan was not acknowledged as a co-recipient of the prize. It is a bittersweet reality that has left the scientific community wondering about this reality

Major Contributions and Challenges

Beyond the Raman Effect, K S Krishnan made significant contributions to magnetism and solid-state physics. His research on the magnetic anisotropy of crystals laid the foundation for understanding how magnetic properties vary depending on direction. This work has far-reaching implications, influencing fields such as material science and engineering.

Krishnan’s career wasn’t without challenges. He faced limited resources and recognition in a time when Indian scientists were often overshadowed by their Western counterparts. Nevertheless, his determination and intellect saw him rise to prominence. In 1947, he was appointed as the inaugural director of the National Physical Laboratory (NPL) in India, significantly contributing to the development of the nation’s scientific infrastructure.

Anecdote: A Lesson in Humility

One lesser-known but heartwarming story about K S Krishnan involves his interactions with students. Known for his humility and generosity, Krishnan once spent an entire afternoon explaining a complex physics concept to a group of young students. When one student asked why he devoted so much time to them, he replied, “The future of science depends on your curiosity today.” This anecdote reflects his belief in nurturing young minds.

Legacy and Influence

K S Krishnan’s contributions laid the groundwork for many modern scientific advancements. His work in magnetism continues to inform research on magnetic materials and their applications in technology. The institutions he helped build, including the NPL, remain pillars of scientific research in India.

Krishnan’s legacy is not just in his discoveries but in the values he embodied: curiosity, perseverance, and a commitment to advancing knowledge. His life is a testament to the power of collaboration and the importance of recognizing unsung heroes in science.

Conclusion

K S Krishnan’s journey from a small village in Tamil Nadu to becoming one of India’s most respected physicists is a story of grit, intellect, and passion. While history may not have celebrated him as loudly as it should, his impact on science is undeniable. As we delve into the ever-expanding realms of knowledge today, we must honour the contributions of pioneers like Krishnan, who laid the foundation for future advancements.


Author’s Note

Reflecting on K S Krishnan’s life, I am struck by the humility and dedication that defined his career. His story is a reminder that recognition isn’t always proportional to the contribution, but true grereminds men advancing the collective good of humanity.
