Open Source Software Makes the Invisible Man

“A University of Liverpool mathematician claims 30-year-old open
source software has cracked the equation that will allow scientists
to make objects–such as humans, tanks or even entire
islands–invisible.

“The mathematical theory builds on earlier research into
cloaking technology by Imperial College’s Professor John Pendry. He
developed artificial materials (or meta-materials) that can make
light sweep around an object, theoretically rendering it invisible.
‘You play geometrical tricks,’ Pendry told PC Pro. ‘You force
[light] particles to go around an object just like water goes
around a stone…'”
