In 1959, Feynman gave a now-famous talk “There’s Plenty of Room at the Bottom”. Back then, the first satellite was just being launched into space and it would take another two years to put a man into space. Transistors, which now are like 100 nanometers in size (too small to see with the naked eye), were huge—about the size of a pencil eraser.
Feynman never used the word “nanotechnology,” as the word didn’t even exist at that time (it was about 15 years later that a Japanese scientist, Norio Taniguchi first used the word ‘nanotechnology’). But he challenged the scientific community to think about how to “write the entire Encyclopedia Britannica on the head of a pin.” Then he told everyone just how he would do it—how to store information by arranging the atoms one at a time. It would take another forty years for someone to really do it. And they did it almost the same way that Feynman said it could be done. In 1965, Feynman won the Nobel Prize in physics—not for his predictions about nanotechnology, but for his work in quantum electrodynamics, QED (calculating how different particles interact with each other).

In 2005, a commemorative stamp honoring Richard Feynman was printed by the United States Postal Service. And on that stamp somewhere, written very small, is a secret message related to QED. Maybe you can find it and write back to us (info@nanooze.org) and tell us what you found out about it.
