Cases

"I teach basically in stories. You can call them parables." — T.W. Eagar

Each case is one such story — an industrial decision, a failure, a career, a material's history — through which Eagar teaches. Every case in the corpus, indexed and cross-linked, with each appearance shown side by side.
