Thought for the month

“You cannot have freedom without a rule of law ... and if you don't have it, what you tend to get is corruption and that is death to freedom, it's death to truth, it's death to honour, it's death to democracy.”

Margaret Thatcher, 1 October 1996.

Big things in Michigan

The most complicated crystal structure ever produced in a computer simulation has been achieved by researchers at the University of Michigan. The icosahedral quasicrystal looks ordered to the eye, but has no repeating pattern. At the same time, it's symmetric when rotated, like a soccer ball with five-fold and six-fold patches. Due to their symmetry under rotation, icosahedral quasicrystals may exhibit a photonic band gap making them of interest for displays and optical communications.
