Nomography and other things.

I found the article on Heaviside an interesting read.

The 13th roots were pretty interesting. What I want to know is what the 500-digit number was that Wim Klein calculated the 73rd root of in 1976. Anyone know where I can find the original number or its root? All I know is that the root is between 6848830 and 7068302, and I can't seem to find a site to read the book (Guinness Book of World Records 1976) online.

[URL="http://stepanov.lk.net/mnemo/mkleine.html"]According to this [/URL], it was a 507 digit number, which puts the root between 8540964 and 8814658 inclusive.

[URL="http://myreckonings.com/wordpress/2011/10/05/the-13th-root-of-a-100-digit-number-part-i/"]This article[/URL] says it has pictures of the 73rd root demonstration. I think the top picture is the 500+ digit number, so you can probably work out the number even though some digits are cropped out.
