Using the Hyperbolic Curve Clock to tell the time is a novel and mathematically satisfying experience. 

The intersection of the angled arm and the numbers marked on the two hyperbolic curves indicates the hour. The curves are physical representations of part a deformed clock face (circle), having become one of an infinite number of ellipses. Some hours "disappear" in the single parabolic form when the plane lies parallel to the angle of a cone...only to reappear in the hyperbolic form "on the other side of infinity".

The pointed hand in the centre below the 'X' shows the minutes - and from above can tell the time the conventional way. Instructions in the pack show just how and explain the mathematics of the clock. 

Watch it move - but note in real time the arm traces the hour in a slow and elegant hyperbolic curve.

The Hyperbola Clock is made of the highest quality polymer, light enough to ensure the mechanism works, but highly scratch resistant. It comes with a ten year guarantee and a leaflet with some mathematical ideas to explore - in a classroom or at home. Now arrives prepacked with a simple three click assembly to avoid damage in transit. Needs a single AA battery.

A perfect gift for the mathematician, or for your mathematics room!
