The Department of Physics, IIT Kanpur, marked a century of one of the most transformative ideas in modern science — Quantum Mechanics — with a special commemorative lecture by Prof. Manoj K. Harbola, Department of Physics, IIT Kanpur.

In his talk titled “100 Years of Quantum Mechanics (1925–2025): What Happened in 1925?”, Prof. Harbola traced the evolution of quantum thought — from Planck’s idea of quantized energy and Einstein’s photon hypothesis to Bohr’s model of Hydrogen atom and the pioneering contributions of Indian physicists Meghnad Saha and Satyendra Nath Bose.

The lecture highlighted Werner Heisenberg’s 1925 paper as the true birth of modern quantum mechanics, marking a paradigm shift in how we understand the microscopic world. Prof. Harbola emphasized that Heisenberg’s work represents one of the finest examples of human creativity and logical thinking — a turning point that transformed both physics and technology, influencing fields from semiconductors to quantum computation.

The event drew enthusiastic participation from faculty, researchers, and students, celebrating a century of innovation, inquiry, and the enduring legacy of quantum theory.
