Intoduction to Isabelle
Isabelle is depicted as putting some weight on the scale since Isabelle should not be counted as a light-weight formal method
She wears a long red dress since in terms of supported logic she is the queen with Higher Order Logic subsuming the expressiveness of all the others
Of course this comes at a price with the stearn teacher/librarian look on her face she punishes and despises imprecise expressions
Isabelle is an allround solution in research and science but sometimes still too far out of reach
