Lecture abstract :

The Bardeen–Cooper–Schrieffer (BCS) Theory of Superconductivity is one of those rare ideas that changed everything—not just in physics, but across science itself. What began as an explanation for how certain materials conduct electricity without resistance became a new way of seeing how collective behavior can lead to entirely new forms of order in nature.

From the ultra-low temperature physics lab to the edge of black holes, from the entanglement of Cooper pairs to the entropy of horizons, the fingerprints of BCS are everywhere. The same mathematics that binds electrons into superconductors now hints at how space-time itself might emerge from entanglement and order. One revolutionary idea has become a blueprint for understanding reality itself—bridging fields as diverse as quantum information,  condensed matter physics, and cosmology, and inspiring technologies like the most advanced quantum computing platforms, including this years Nobel Prize in Physics.

BCS reminds us that the deepest scientific advances often begin with a simple question and end up transforming how we think about the world. Whether you work in biology, mathematics, engineering, or art, this story offers a glimpse of how imagination and collaboration can unlock entirely new realms of understanding—and how those moments of insight can ripple outward, shaping the technologies and ideas that define our future.
