My talk is called 'The Pencil and the Keyboard: How The Way You Write Changes the Way You Think'. In it, I'll talk about the science of writing: Why handwriting is better for taking notes, remembering and big-picture thinking -- but why typing on a computer is better for composing your ideas and communicating with others. It'll all be grounded in the story of how I became a full-blown pencil fanatic -- a person who buys rare pencils and always has a sharpener in my pocket.
