I can't find it for an affordable price anywhere. Is this book made of gold or something? I hate reading on my PC. Sorry /prog/, but I won't be reading it.

If the bubble was five feet thick, and the inner chamber 10 feet wide, the density of the bubble would be
(volume of the steel) * (density of steel) / (volume of bubble)=
[4/3 * pi * (10^3 - 5^3) ft^3] * [500 lbs/ft^3] / [4/3 * pi * 10
^3] =
437.5 pounds / ft^3
which is much higher than the density of water, 62 lb/ft^3.
