```I haven't posted in awhile, having my hands full doing
heavy duty logistics in South Africa and the Kingdom of
Lesotho.

My reading of late (just finished) was Neal Stephenson's
Cryptonomicon, a science fiction novel (and NYT best-
seller) which takes me back to my youth in the Philippine
islands (where I went to high school -- and learned to
scuba dive from exMarine Gill Gilleland), and to other
places.  I highly recommend the book.

Why this is relevant to edu-sig is there's a lot to write
about cryptography, using the Python language.  I've
been meaning to explore this more, jumping off from
my http://www.inetarena.com/~pdx4d/ocn/numeracy2.html
wherein I explore prime numbers, and come up against
the difficulty of finding the factors of very large
numbers.  If you take a huge number that factors
uniquely into two primes, you could think of one as
the private key, the other as the public key --
something like that.

I'm separated from my eBook on the Standard Library at
the moment, but as I recall, Python already ships with
at least one crypto algorithm.  But there's a lot more
we could be doing, to build bridges between the
"math through programming" initiative (which I've been

Anyway, I invite people to consider a role for Python
at this juncture -- could be a great place to do some
original and useful curriculum writing, IMO (think
elementary school for example -- no need to start in
the densest areas -- and do some simple substitution
codes (plus there's always using algorithms to try
cracking such simple codes (then moving on to the
next level)).

PS:  another link to Cryptonomicon is the "math teacher
as storyteller" thread -- thinking of math teaching as
an opportunity to tell stories with math content inter-
weaved.  Stephenson's book contains many examples of
this.
