Department of Redundancy Department

I liked the note at the end about Pair Instructing. I forget many disciplines haven't embraced pairing to the degree programming has.

In college I took an elective course taught by a husband and wife pair from the geology department. They interacted with each other a lot, and it definitely encouraged us to join the conversation with questions and comments of our own. Overall, it was a really good class. Okay... so it was a survey of bad science shown in environmental disaster movies, but the teaching style was an important factor as well.

The author holds a rather loose definition of redundancy. If a user-friendly loop construct is redundant because you could use use jumps, then a car is redundant because you could just walk everywhere. Phones? Redundant, just go over in person and talk. Running water?
