The Crystal Structure of Bubbles in the Wet Foam Limit
(2006)We have observed a rich variety of three-dimensional crystal and defect structures spontaneously formed by small (diameter 200 µm) bubbles in a wet foam. The observations confirm and extend those made by Bragg and Nye in ... -
Variation of average coordination number with liquid fraction for two-dimensional foams with finite contact angle
(2021)We present Surface Evolver computer simulations for two-dimensional (2d) foams in which the contact angle at which liquid films and Plateau borders meet is non-zero. We determine the average coordination number Z of bubbles ... -
What is the Real Price of Gold and How Would We Know?
(2011)We survey, very briefly, some conceptual and empirical issues that bedevil the identification of a fundamental price for gold and consequently the identification of a real gold price.
