Enigma_(crittografia)_-_Museo_scienza_e_tecnologia_MilanoOn Sunday, March 26, at 9 a.m., please join CBS congregant Newman Fisher for a talk on Jewish cryptology.

Cryptology literally means “secret writing.” More generally, the word describes the creation of protocols used to write messages that can be understood only by one’s intended audience and not by any adversaries. The history of cryptology is long because the practice is an ancient one.

Newman will examine examples of cryptology through the ages and across a variety of cultures. He will also highlight how cryptological technologies have evolved in modern times, focusing especially on the Jewish influence on current practices. No mathematical background is necessary.

The Breakfast Club currently meets four times each year on a Sunday with an informal talk on topics of interest to the Jewish community. Speakers have included many community leaders of the San Francisco Jewish Community, along with members of CBS. Meetings are held at 9:00 a.m. and start with a delicious breakfast.

Cost: $80 per couple or $40 per individual for all four meetings; $15 for single session drop-in. You can pay on the day-of or drop off your payment at the CBS Administrative Office during business hours.
