Hassium is named after Hessen, a German Fedral State, and Darmstadtium is named after Darmstadt, a German town … I think it lies in Hessen as well, but anyway, it's a University town.
For your fun : "Darmstadt" would literally translated be "Guttown".
There funny named here, you know.
Hessen, by the way, has connections to the aristocrat house of Oranienburg-Nassau - Oranje -> het Nederlande and Nassau -> yes, you have already guessed it : Nassau in the U.S.A. …
All these three things are related to one another, although I don't quite remember how.
But you don't need to know that anyway.
