Скачать или смотреть The Foundation of LASERs: How Einstein’s Equations Made Light Obey Us | Neil deGrasse Tyson

In this video, Neil deGrasse Tyson explains how Einstein’s quantum equations led to the concept of stimulated emission, the key idea behind LASER technology.

We explore how pure theory turned into one of the most precise tools humanity has ever created, why LASER light is different from ordinary light, and how Einstein’s work reshaped modern physics and technology. From quantum mechanics to real-world applications, this is the hidden story of how light learned discipline.
