Why I Love the Khan Academy
Though I'm a fan of Feynman anecdotes, I've always disagreed with the point of the one used in this article.  Names are important.  You know what you get by knowing the name of the brown-throated thrush?  You get an identifier by which to look up all the collected knowledge of humanity on the brown-throated thrush, and you gain the ability to talk about it with other people.In the online SICP lectures there's a nice point about names and how they give you power over things, but I couldn't find it right away.
