From a fascinating article in The New Yorker about the Cloisters, the Unicorn tapestries, art restoration, number theory, supercomputers and more.
they were working with I.B.M. to design what may be the world’s most powerful supercomputer. The machine, code-named C64, is being built for a United States government agency....When the machine is finished, it will contain two million processors and fourteen thousand hard drives. It will use two and a half million watts of electricity—enough to power a few thousand homes. Two thousand gallons of water per minute will flow through the core of C64 to keep it cool. If the pumps fail, it will melt down in less than ten seconds.

Cool--I want one.
