Hate crowds? Need your “personal space?” Negatively charged electrons do too! This is Sandra Tsing Loh with the Loh Down on Science. To understand electrons, scientists have developed a special technique called density functional theory – D-F-T for short. D-F-T is used to predict how electron crowds move in an
