Time and Mathematics

I have once blogged about a clock for math geeks but today I found a much cooler clock in Walyou, my favourite Tech website.

This really needs more advanced math than I am teaching.



Walyou has intoduced many math clocks earlier and I decided to check what else could be found in the net.

This is the first one I spotted in StumbleUpon almost 2 years ago:



What I found funny was the discussion in cnet news. The expression for 7 gives 6.999... and the argument about 0.999... being equal to 1 continues. Maybe I should blog about that next.


MathematiciansPictures.com has nice clocks featuring famous mathematicians. This one is my favourite, since it contains the most beautiful equation. The Euler Clock:




For a reminder, this is the one I introduced before. It also has some inaccuraties. 9 is only an estimate and 7 has two solutions.

POP QUIZ MATH CLOCK


I also love this Binary clock. I have one at home, a mother's day gift from my children. This one is from ThinkGeek




Kaboodle had this clock made of numbers

Karlsson Mixed Numbers...


This is a unit circle clock and would be really helpful learning trigonometry. Found in Law9

This cool but confusing clock I found in WebUrbanist, which has altogether 24 different Modern Clock designs introduced.




Libraby of Math has a huge collection of math related clocks.

Large Binary Wall Clock
a different kind of binary clock


Large Wall Clock
a trigonometry clock


Large Square Root Wall Clock
a square root clock

This is actually a watch from Watchismo, but I think this would be much better on the classroom wall.


Even though I love math, I think this Turing alarm clock is too much... My husband and daughter want to continue sleeping after the first alarm. I would go crazy when I had to listen to all the alarms several times! When I wake up, there is no chance to continue sleeping; I am awake.

Unique clock designs. I would probably had a hard time telling what time it is based on their designs. I think this clock is made for the math geniuses. :D

The clock designs look beautiful and unique. I love the ones with the mathematical equations.

Its a beautiful clocks collections..!!!Popular wall clocks are normally always bought in the analogue style, whereas the desk varieties are equally popular in digital or analogue format.
