PRODUCT DESCRIPTION FOR Irrational Numbers Wall Clock

EXCLUSIVE! In math, irrational numbers are those that can't be represented by simple fractions. Two examples are pi and the square root of 2. Designed by a mathematician, for mathematicians (and others in the know, like engineers and scientists), this clock tells time in irrational numbers logically placed on a 360-degree circle. For example, pi (3.14159...) is just a few degrees past where the 3 would be on a regular clock face. Black with white markings and hands, metal clock runs on 1 AA battery. 12" diameter.

      Got this for my husband for his birthday and did not work called them and sent another one immediately. This one works fine. At Christmas was a great conversation piece w/all the kids and adults trying to figure out what symbols were.

        I bought this clock for my grand daughter who is in accelerated classes for Math and is showing great interest in engineering. She loved it and so did everyone else in the family. Since my step daughter teaches calculus, and now with my grand daughter, I am on the look out for great math gift ideas. Thank you for the clock.

        Great Housewarming gift for 2 New PHD Mathematicians in their first home.

        It's unfortunate that dial was slightly smeared, however.

                        This clock is poorly made and not with the money. The face looks like it can peel off over time. When I received mine the face was warped, the hands were bent and touching the face so it would not work. I hade to bend the hands to make it work. Batteries in clocks like this last for many months, sometime over a year. This clock stopped after a little over one-month.
