Pinnings play an important role in the classification of reductive algebraic groups. Even though the subject can get abstract, pinnings are actually quite concrete. We'll write down matrices to describe pinnings of classical groups like $\operatorname{SL}_n$ and $\operatorname{Sp}_n$ and talk a little bit about how pinnings fit into the classification theorem.
