The Japanese do some incredible stuff. I remember in the 60’s, there use to be an international contest. Someone would design something, send it to the next country and they would try and improve it.

Back in the '60s some Americans created "the thinnest wire in the world" and sent it to the Swiss as a challenge to do better. The wire came back with no note, and nobody could figure it out - until, under a microscope, they saw the wire had a hole drilled through the core.

I could be wrong. I thought it was Japan.
