1. I feel that the most difficult thing for me from the reading was thinking in terms of matrices and vectors and not seeing them the way I want to think about them there in the text. Once I went off to the side in order to see it in the way I imagined it, it became easier for me to visualize what was being described. I would have like more visuals in the actual text, but it did describe it more than enough for me to figure it out in a way that made sense to me.
2. I found the methods for cracking this cipher to be very interesting. How does somebody come up with that? It makes sense to me to compare expected values against the frequency at which a given character generally appears, but I would not have thought to compare dot products in order to do this. It would be really nice to try using this method once or twice in class!
