The Jerusalem Chords Bridge, Israel, was built to make way for the city's light rail train
system. Its design took into consideration more than just utility — it is a work of
art, designed as a monument. Its beauty rests not only in the visual appearance of its criss-cross
cables, but also in the mathematics that lies behind it. So let's take a deeper look at it. </div>

<b>Runner up in the schools category</b>. Dusty books, chalky blackboards and checked shirts are all things usually associated with maths. But according to <b>Jonathan Tims</b>, pubs, hot chocolate and cats can be far more inspirational. Join him on a trip through shadow land. </div>
