Great Courses: Math & Magic

The Pound Ridge Library is pleased to announce the continuation of a series of lectures which mark the eleventh year of courses which are part of the library’s continuing presentation of a new educational concept in life-long learning: a series of DVD seminars from The Teaching Company/The Great Courses encompassing a wide variety of subjects, given by outstanding scholars from major colleges and universities throughout the United States. This program, the first of its kind in the country, is designed to provide collegial, small group-setting for courses “you didn’t get to take at college, but wanted to.” The seminars, developed by the late Lawrence Brotmann of Pound Ridge, NY are held at the library on Thursdays at 12:30 pm and consist of four 30-minute (closed-captioned) lectures per session, most from 3 to 6 weeks per course.

Registration is not necessary but parking is limited. The library encourage carpooling or being dropped off.

Course Overview

Try this: Arrange an ordinary deck of cards so that the colors alternate red-black, red-black, all the way through. Now have someone cut the deck as many times as they like. Deal off a stack of cards, one card at a time, that roughly divides the pack in two. Invite someone to shuffle the two stacks together. Then deal cards from the top in pairs. Your audience will be astonished that every pair has a red card and a black card. How can that be?

Nothing can amaze quite like an expertly-executed magic trick. Ideally, only the magician knows how truly simple the deception is. After watching Math and Magic, you will know that this trick and its many variants rely on a remarkable property of patterned sequences called Gilbreath’s principle—named after an amateur magician who was also a mathematician. Magic is full of such wonders, as you discover in these 12 illuminating half-hour lessons presented by one of The Great Course’s most popular lecturers: award-winning Professor of Mathematics Arthur T. Benjamin of Harvey Mudd College, who is himself a professional magician.

Renowned in TED Talks, The Colbert Report, and other popular media as a “mathemagician,” Professor Benjamin teaches you the techniques and secrets behind dozens of great math-based tricks. Even if you are a numerical novice, you will look like a prodigy after mastering these math-inspired showpieces, which require no skills beyond basic algebra—and a bit of showmanship.
