How to Give a Talk
summary
Science is collective so talks sit between one‑on‑one conversations and papers and must manage attention by motivating a problem, giving a roadmap, and explaining one key idea in depth. Example: using generalized algebraic data types (Vector, nil, cons) requires existential types to type functions like filter, which makes subtyping ambiguous and can cause exponential backtracking; the fix is polarization and focusing to separate rules and produce a syntax‑directed, efficient algorithm. Ends with a summary slide and pointers to the paper and implementation.
