Life & Legacy

Early Life and Education

Prof. Krori completed his Bachelor of Science degree from Karimganj College before earning his Master of Science in Physics from the University of Calcutta in 1953. His passion for theoretical physics led him to pursue independent research while continuing his teaching career. In 1971, he received his PhD in Theoretical Physics from Jadavpur University, Kolkata, demonstrating his commitment to academic excellence and scientific discovery.

Academic Career

Prof. Krori began his teaching career as a lecturer at Karimganj College before joining Cotton College in Guwahati in 1955. During the 1960s, when research in general relativity was almost absent in Northeast India, he laid the foundation for advanced studies in this field. He later became Professor and Head of the Department of Physics at Cotton College, transforming the institution into an important centre for theoretical physics research. From 1987 to 1991, he served as the Principal of Cotton College, where he strengthened academic standards and encouraged scientific research. Even after retirement, he remained active as a UGC Emeritus Fellow and continued contributing to physics education and research.

Research Contributions

Prof. Kamalendu Deb Krori is best known for the famous Krori-Barua Solution, developed in 1975 with his student J. Barua. This exact solution of Einstein's field equations describes a singularity-free charged fluid sphere and remains one of the most widely cited contributions in relativistic astrophysics. The model continues to be used by researchers studying compact stars, neutron stars, strange stars, and gravitational physics across the world.

Another landmark contribution came in 1982 when Prof. Krori and his collaborators demonstrated through theoretical calculations that neutrinos must possess a small but finite rest mass for consistency with Einstein's theory of general relativity. At a time when neutrinos were widely believed to be massless, this prediction was considered revolutionary. The discovery of neutrino oscillations by the Super-Kamiokande experiment in Japan in 1998 later confirmed that neutrinos indeed have tiny masses, validating the significance of his theoretical work.

Throughout his research career, Prof. Krori explored exact solutions of Einstein's field equations, cosmology, black holes, string cosmology, quantum mechanics, higher-dimensional gravity, and particle physics. He authored nearly 150 research papers published in reputed national and international scientific journals and supervised 16 PhD scholars, many of whom later became respected physicists.

Books Written

Prof. Krori has also made significant contributions to physics education through his textbooks, which continue to be widely used by university students.

Books authored include:

  • Fundamentals of Special and General Relativity (2010)
  • Principles of Non-Relativistic and Relativistic Quantum Mechanics (2012)
  • Advanced Heat and Thermodynamics (2004)

These books simplify complex scientific concepts and have become valuable learning resources for physics students across India.
