"Bubble Trouble: It's taken 170 years, but now the problem is solved," by Ian Stewart. New Scientist, 25 March 2000, page 6.

Everyone has seen double soap bubbles. Mathematicians suspected for decades that this familiar shape is the most efficient possible, but rigorous proof of the fact remained elusive. A breakthrough came in 1995, when it was shown that this configuration is the most efficient for equal sized bubbles. This article describes a new result that proves that the same holds true for bubbles of different sizes.
