Scientists claim to have created the world’s smallest three dimensional map—a map of the Earth so small that 1,000 of them could fit on one grain of salt.
A team at computer giant IBM accomplished this through a new, breakthrough technique which uses a tiny, silicon tip with a sharp apex—1,00,000 times smaller than a sharpened pencil—to create patterns and structures as small as 15 nanometre at greatly reduced cost and complexity.
