Carnival of Math 二十

November 3, 2007 pm30 8:14 pm

And quite a nice Carnival #20 it is. Murray of SquareCircleZ has created a slightly-themed carnival. Since he blogs from Asia, the posts are numbered with Chinese, binary, and our Arabic numerals. That “=” “+” in the title? Nope, it’s the digraph for 20…

If you are here, you’ve probably already seen my contribution (#13).

High School student submitted on encoding…

More interesting? Entry #4 This is the first ever CoM post by a high school student: Andy found a flaw in a polynomial-based encoding system (he shows it is not as strong as it claims. In fact, it would be nice to show that it is not secure, but I don’t know if that is possible, and I am reasonably certain that, even if it were, the math would be beyond my skills.)

    Just so you know, it is secure.

    Err.. not “our Arabic numerals”, Jonathan – actually Hindi characters :-)

    Hmm. I thought the idea was Hindi, but the actual forms were adapted from the Phoenicians (and called, in English at least, Arabic). Did I get that backwards?

    And thanks for the “secure” link. Quite informative and clear.
