- History
Rome's territory peaked under Trajan in 117 and his successor abandoned the newest provinces within months as impossible to hold. The empire's greatest extent lasted a matter of weeks.
- Science
Element 117 needed a berkelium target that only Oak Ridge could produce, flown to Russia and used before it decayed. Tennessine is named for the state that made the ingredient rather than for the laboratory that made the element.
