Modern technology can seem mind-bogglingly complex. But beneath the surface, it can be beautifully simple.

Nails, springs, wheels, magnets and string - these individual wonders have built our modern world. Each component has a long history and is the result of many iterations and refinements. Together, they have enabled humanity to see the invisible, build the spectacular and communicate across vast distances.

Join award-winning engineer and broadcaster Roma Agrawal as she deconstructs our most complex feats of engineering into seven fundamental inventions that have changed our lives - and our societies - in dramatic ways.
