# The Mathematician’s Clock

The clock below is called the Sheldon Cooper’s clock (I searched for it at Amazon, but the best that I could get is  this math clock). If this clock exists, I really want to buy one.

I am also confused with 0b. Is it a hexadecimal number or a Greek number?  In hexadecimal, B stands for 11, and in the Greek system, according to one of the comments in the clock’s website, 0 which is actually $\theta$ stands from 2, and $b$ stands for 9, so $2 + 9 = 11$. I am not sure how Greek numerations work, so I don’t really know which of the explanations above is correct.

What do you think?
