 You cannot buy this amazing
Chart of Electromagnetic
Radiations anymore, but thanks to the folks at Lawrence Livermore National
Laboratory, extremely high resolution image files of it have been placed on the
flickr website.
The chart showed up in Popular Science magazine recently.
W.M. Welch Manufacturing Company (now
Sargent Welch) originally sold the wall poster in 1944, so the content does not
reflect knowledge gained in the last seven decades, but its sheer artistic beauty
and amazing content is enough to bring a tear to a technophile's normally staid
eye. Even if you do not print out and hang it on your office wall, you owe it to
yourself to at look at the 10000x6958-pixel version. The camera used was undoubtedly
a little higher quality than my personal point-and-shoot mode.
Unfortunately, Sargent Welch no longer sells this chart; however, they do sell
many other very fine charts that you might consider, including a newer EM spectrum
chart.
