What makes you Nerdy?
★ N: Nitrogen is a common element in the universe, estimated at about seventh in total abundance in our galaxy and the solar system. Colorless nitrogen gas makes up 78% of the atmosphere! Liquid nitrogen is great for making ice cream and preserving wine.
★ Er: Erbium is used to dope fiber optic cables to improve their information carrying capability, which it does by helping to amplify the signal. It can also impart interesting colors to pottery glazes.
★ Dy: Dysprosium compounds are used in the coatings of many hard disk drives to record digital data as field orientations in nanoscale magnetic domains. Other than that, dysprosium has few applications.
