Using a spiral arm to tell the time is a novel and mathematically satisfying experience. Made of high quality scratch resistant polymers, it is light enough to work its extraordinary mechanism but built to last. The clock comes with a ten year guarantee and a leaflet with some mathematical ideas to explore - in a classroom or at home. 26cm x 11cm. A perfect gift for the mathematician, or for your mathematics room!
