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.

Speedy suanpan

The first suanpan, calculating pan or Chinese abacus, was mentioned in second century BC scrolls and would have been in use for many years prior to this. The current Sunway Taihu Light supercomputer can perform 93 million billion calculations per second (93 petaflops) and heads the latest Top 500 list of supercomputer performance. A machine with ten times this speed is at the prototype stage.
