No less a genius than Albert Einstein proved that time was not a constant. Now you can make the same law apply to your brain. With the Albert Clock, you’ll be constantly – in a challenging-but-fun way, we promise – using your math skills to calculate the hours and minutes of the day. Wherever you are in the universe, that is.
And lest you think the Albert Math Clock is the perfect way to trick the budding young mathematicians in the house into going to sleep an hour early: there are four levels of difficulty on this calculating timepiece, leaving plenty of opportunities for adults to do the math, too.
