Cryptography -- an MAA lecture and a poem

     Living near the Silver Spring metro station, on the border of Washington, DC, makes travel to the offices of the Mathematical Association of America (MAA)  an easy trip for me, and I am able to enjoy occasional lectures at MAA's Carriage House Conference Center.  On December 9 I was fortunate to attend an entertaining and informative lecture on  "Cryptography:  How to Keep a Secret," by UC Irvine math-computer-science professor (and Numb3rs consultant), Alice Silverberg. (Podcasts of lectures are available at the MAA site.)
