Euler's Product

Everyone knows Euler’s famous identity, linking the imaginary unit to trigonometric functions:

$$ \mathrm{e}^{\mathrm{i} \pi} = -1 $$

But another remarkable identity is also due to Euler, this one linking the set of prime numbers to an analytical function:

How Has Software Development Changed?
