Popular Science article
The page link to the Popular Science article is wrong; it should be updated to https://books.google.com/books?id=7igDAAAAMBAJ&lpg=PA11&pg=RA1-PP2#v=onepage&q&f=false

And it's not an unnumbered page, it's page 86 --- the table of contents mentions this, and the last page with visible numbers is page 83, three pages before.
