Add RecipientIn 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.

Irrational Numbers Wall Clock 19 20
not worth the money The clock came in with a bent minute hand and the screen printed numerals were spotty as if they did not use enough pigment. It was over $40.00 for a clock of questionable quality. Lastly, Skymall took 2 weeks to get the order delivered. February 14, 2013
Love it! Received this clock as a present and I love it. I majored in math/physics in college and this clock is right up my alley. Stimulates a lot of conversation. February 1, 2013
Great for the Math Geek in all of Us! got it for my husband as a Christmas present. he is a mathematics teacher so he absolutely LOVED it, even told me how accurate the equations really were..like I care. BIG conversational piece when he hosted Poker with his fellow math teacher buddies last week. HUGE! January 22, 2013
Great gift for number lovers! We purchased this gift for my husband's mother, who is a math teacher and she absolutely loved it and got a kick out of the irrational numbers. January 18, 2013
