For problem number 17 in section 2.4, the vector b is a column vector. The reason for this is because the entries are separated by commas rather than just spaces.

This is done in order to preserve uniform line spacing in a paragraph. I think I may have mentioned this in class but I’m not sure.

Before he was a grizzled old Obama-chair-hating, PBR-swilling, Oscar–winning curmudgeon, Clint Eastwood starred in many of director Sergio Leone’s spaghetti westerns. They’re some of my favorite movies ever, not least because of Ennio Morricone’s brilliant scores. The theme from The Good, The Bad, and the Ugly is, of course, the most famous, but there is a lot more to his work. A Gringo Like Me is a pretty fun song that enjoyed a slight bump in popularity after the Lonely Island dropped it in their criminally underrated film Hot Rod. And I’ve always loved the pocket watch theme from For a Few Dollars More; the tune is good on its own but absolutely brilliant in the context of the film, which is tighter and leaner than TGTB&TU, if not nearly as epic and awe-inspiring.

Anyway, the reason I’m thinking about Sergio Leone movies is because of this incisive piece of commentary from Jack Handey:

“If you’re a cowboy and you’re dragging a guy behind your horse, I bet it would really make you mad if you looked back and the guy was reading a magazine.”
