Linus Pauling's 1960 book The Nature of the Chemical Bond 3rd ed., Cornell University Press, contained a diagram of a clathrate with the same
topology as the Weaire-Phelan structure. This book was sitting on my father's
bookshelf 10 feet from me as I was trying to beat Kelvin's foam back around
1991, and if I had
happened to open the book to page 471, I like to think I would have won
the race to beat Kelvin.
Back to beating Kelvin.
