London 2012 Olympics: Creating tiny torch is nano mean feat

AN EDINBURGH student has created his very own Olympic Torch, which is 100,000 times smaller than the original. Peter Kremer, from Heriot-Watt 
University, reproduced the torch on the nanoscale while carrying out research into light particles.

The 28-year-old’s invention measures nine micrometres in length and tapers down from a diameter of 1,600 nanometres at the top to 80 nanometres at the base. A nanometre (nm) is about a hundred-thousandth the width of a human hair.
