MADRID, Spain (AP) - Physicists in Spain are celebrating the 400th anniversary of publication of "Don Quixote" in a very small way: they wrote the first paragraph on a silicon chip in letters so tiny the whole 1,000-page book would fit on the tips of six human hairs.
The feat — just for fun — shows off a data-storage technique developed years ago by the Microelectronics Institute of Madrid, part of the government's top scientific research agency.
It uses a device called an atomic force microscope, which runs a ceramic or semiconductor tip over a silicon surface in much the same way as a phonograph needle scans a record.
