Our lives have become so dependent on electronic technology, we could barely imagine a world without it. Yet in 1943 the president of IBM announced “there is a world market for maybe five computers“. Even in 1977 the founder of the Digital Equipment Corporation stated that “there is no reason anyone would want a computer in their home”. This is because computers were rare, expensive, complicated to use and were so huge, they took up the entire space of a room. How did we go from these exclusive devices used by a select few, to the tiny pocket-sized gadgets we all have today?

It all comes down to the invention of the transistor and the microchip. These are fabricated from silicon, one of the most common constituents of sand. In this talk, find out how we go from a simple particle of sand to complicated, modern electronic devices. We’ll discuss the evolution of electricity and the remarkable properties of silicon that can be manipulated to produce varied technologies ranging from lighting, television, digital cameras and solar panels.
