About this episode

This episode explores the precision of atomic clocks and the quantum physics behind their operation.

Ever wondered how we measure time with such incredible precision? In this episode of Subatomic Tanvi, we’re looking past the pendulums and quartz crystals of traditional watches to explore the high-tech world of atomic clocks. Join the conversation as Tanvi breaks down the quantum physics of energy levels, resonant frequencies, and the photons that make these devices the most accurate timekeepers on the planet. From the basic principles of atomic transitions to a step-by-step look at how they function, this episode reveals the hidden subatomic rhythm that keeps our modern world in sync.
