Diagram?

This page is in need of a diagram. I think I know how it works, but not well enough to trust myself to draw such a diagram yet. Shinobu 02:48, 4 January 2007 (UTC)[reply]

coherent light

Johannes Gutenberg and magic mirrors

http://en.wikipedia.org/wiki/Johannes_Gutenberg

 Gutenberg had a plan (that went badly) to sell magic mirrors to religious pilgrims visiting long-dead Charlemagne's base, Aachen. The Chinese items described in THIS article would, if the symbol on the mirror-back were a Christian one, seem to me to be ideal for such sales, just the right sort of miraculous, mysterious, mystical light-based phenomenon. I was wondering if anyone might want to pop over to the Wikipedia article on Johannes Gutenberg (URL above) and read what I wrote there (ON THE TALK PAGE, not the ARTICLE PAGE). There are reasons (not perhaps very strong ones) to think an independent European discovery of this metallurgical-optical trick to be unlikely. Is there any way on Earth that Gutenberg could have received the knowledge of the production of these wares via a human chain of transmission that goes back to these ancient Chinese mirrors? I'm not suggesting that Gutenberg learned it from China. Only that he learned it from someone who learned it from someone ... who learned it from someone in ancient China. And this is only speculation. I just wonder if there is any possibility at all that Gutenberg's magic mirrors and the Chinese mirrors of THIS article could be the same technology.69.86.131.77 (talk) 09:45, 29 May 2013 (UTC)Christopher L.
