What do you think of when we say the word “Crystallography”? Some form of hippie healing? Or maybe small decorations? Well, crystallography is none of that, but instead an accepted and extremely valuable science! Whenever scientist want to know how a material is ordered at a molecular level, crystallography is the go-to-guy. Even though most materials doesn’t look like crystals, they have a crystalline structure at the atomic level, and it has an enormous effect on the properties of the material. Steel has such a crystalline structure and it is the source of its strength. Even complex molecules like DNA can be crystallized in order to find out more about how it works. In this video, The Royal Institution walks us through the history of crystallography and explains how it is used to understand materials better. A must see for any material nerd like us 🙂
