A professor at Cornell and his students have invented a paper microscope capable of 2000 x multiplication. The design is printed on card stock paper and contains an LED and a watch battery. Projected cost of around $1 or less would make it easily available to health workers in third-world countries.

This sounds marvelous to me. The inventor's dream is to have a microscope in the pocket of every student. At that price, I think it could come true. I hope they patent the idea. It would make a nice return on investment.

If you don't care for reality, just wait a while; another will be along shortly. --A Rose
