Evolving invention of Fiber Optics 🧵 The invention of fiber optics is one of the most powerful stories in human innovation, tracing how we learned to control and transmit light itself. It began in the 1840s, when Daniel Colladon and John Tyndall demonstrated that light could bend inside a stream of water through total internal reflection — the same principle that powers fiber optics today. In the 1930s, Dr. Heinrich Lamm used tiny glass bundles to transmit images, paving the way for optical ima
