An eyebrow raiser from George Gilder’s The Silicon Eye (W. W. Norton & Company, 2005), a history of the development of the digital camera:
“Leading-edge clean rooms at companies like Intel or National Semiconductor are ‘class ten’ or even ‘class one,’ meaning that there are between zero and ten such particles, making a microchip factory tens of thousands of times cleaner than a hospital’s cleanest surgical facilities” (p. 53).
Wow.
