Light is one of the most basic and essential parts of the universe. It’s also where the journey into quantum science, the branch of science that studies how the tiniest particles in the universe behave, begins. From the glow of heated objects to the puzzling behavior of tiny particles of light, light has helped us discover how the quantum world works.

Share your visual works on light and quantum science. Selected submissions will be showcased on UNESCO’s website.
