  1. Jason,

    Thanks for your comment over at my blog. It was definitely a bit of a transition taking over classes midyear. However, things are running MUCH smoother now. I look forward to returning next year where I can start every one of my classes from day one.

    Also, I’m enjoying the posts you’ve got going on here. A nice space to check out mathy stuff. Good work! I’ll definitely be visiting.

    Actually, is it…

    1. A badly written pi?
    2. His own symbol for pi?
    3. A paper clip?

    Speaking of failing math notation, you may be interested in my Towards more meaningful math notation.

    Also, I will be submitting an article for the Math Carnival (seeing as how I just missed out on this week’s one over at Tyler & Foxy’s).

  3. His own symbol for pi. His symbol for e is the same thing, only backwards.
