TED-Ed: The story behind your glasses - Eva Timothy

The video explores the evolution of optics over 500 years, starting with practical needs that led to advancements in lenses and spectacles. It highlights key figures like Robert Hooke, who advanced microscopy, and Galileo, who refined telescopic lenses to challenge existing astronomical beliefs. Isaac Newton's experiments with light and color furthered understanding, leading to the development of the reflecting telescope and the theory of gravitation. The video concludes by reflecting on modern optics' capabilities and the ongoing potential for discovery.

What questions remain about the nature of light and color that were posed by scientists like Newton?

In what ways have advancements in optics evolved from the time of Newton to the present?
