If you're interested at all in mathematics (from a purely entertainment perspective), I highly suggest the book 'The Man Who Loved Only Numbers" by Paul Hoffman. Very interesting and you don't need a degree in Math to read it.

were you spying on my math methods class last night? we were talking about math patterns and here you are with some great examples. I shared this link with a bunch of classmates just now..

That's so cool! No spying - I just like odd stuff and thought this was pretty interesting. btw, I just figured out how to do future posts under my own name, Trey was starting to get questions about some of my other posts...
OK let me see. I scrolled down the entire site and here is the score:
Laura's posts - 2 comments (3 including this one, even though one post is Laura's); Trey's posts - 0, that's zero, comments.
Would it be inappropriate to ask if Laura could start her own blog? Math and Food would be a nice combo I think.
Anonymous -
Thanks for the support (?) but there are no plans for a Laura-only blog at this time. All I'm trying to do is amuse myself and doing a blog of my own would be way too much work!
btw - I have the feeling that your comment is more of a slam on your buddy Trey than a call for more Food and Math posts...
