Our Professor, which doth have tenure,
Feared be thy name.
Thy sets partition,
Thy maps commute,
In groups as in vector spaces.
Give us this day our daily notation,
And forgive us our obtuseness,
As we forgive tutors who canot help us.
Lead us not into Lye rings, But deliver us from eigenvalues,
For thine is the logic, the notation, and the accent, That confuses us forever. Amen.
