I really like the naming of things after their discoverers/inventors.
I'm picturing a mathematician getting upset:
"How dare you speak about Friedrich Gauss like that. He dragged that universities astronomy department out of the stone age, even after the death of his first wife..."
The history of the people helps me with remembering the concepts.
I'm imagining them logging your call then saying 7 years from the last record. If they follow up internally a couple weeks later, when you call back 7 years later they can repeat the process.
