These two are research partners in the lab at Canterlot. They are two of few scientists in Equestria, because Equestria is more interested in magic than science(probably).
 
Each has necklaces, Time’s is a planet and Wave’s is an electron p-shell. They both keep their mane tied for safety measures.
