Musical Number Magic

grandpa mike talks symmetry and music for bright youngsters

Effie is five and irrepressible. Dee-Dee is eight, and like many mathematicians she also enjoys music. Grandpa Mike introduces them to symmetry the way mathematicians look at it, surreptitiously introducing them to some of the concepts behind Group Theory. They play with cardboard cutouts, learn a card trick, and then go on to think about music. This book is intended to stretch bright kids from 8 to 14, and plenty of older people, too.
