Here is an alarm clock that cannot be turned off by pressing a button but can turn off on its own only when you are able to solve a few arithmetical problems in a row. This unique Turing Alarm Clock is the invention of Nick Johnson of Brooklyn. The problem with all alarm clocks or may be to be precise with the owners of these alarm clocks is that we can easily go off to sleep by simply pushing the off button of the alarm. In no way this piece of machine can cajole us to keep awake. However, it is different with the Turing Alarm Clock, until and unless we are able to solve correctly a few sums will this ingenious alarm clock stops ringing. However, if you think you are a mathematical genius who can solve sums even in your dreams, especially as it is possible after some days when the question bank repeats the same problem, well then this alarm clock is not for you.
