Creating a New Universe: The Story of the Crystal Discovered by the Duality of Light and Electron

The study of crystals is like the beginning of solid state physics. Crystallography was developed rapidly with the discovery of X-ray. Recently, the era of physics is enriching with the emergence of new material groups such as graphene, topological insulators, and TMD materials. In a way, it is very interesting to see that the providence of the universe and the philosophy of life are reflected in the small crystal structure. However, unfortunately, little is known about when and how crystal growth began. How did our ancestors in the beginning grow and study crystal? This article examines the history of early crystal growth, the development of crystallography, and the relationship between crystallography and physics.
