"A TRUE MINIMAL SURFACE is more properly illustrated by a soap film, which has equal pressure on inside as outside, hence is a surface with zero mean curvature. A soap bubble is a closed soap film: due to the difference in outside and inside pressure, it is a surface of constant mean curvature." https://lnkd.in/d5zN4He View in LinkedIn

WORLDWIDE OBESITY DOUBLES. "Worldwide obesity has more than doubled since 1980. In 2014, more than 1.9 billion adults, 18 years and older, were overweight. Of these over 600 million were obese. 42 million children under the age of 5 were overweight or obese in 2013." https://lnkd.in/db6_hrx View in LinkedIn

MINIMAL SURFACE PROBLEM. "Soap bubbles are physical examples of the complex mathematical problem of minimal surface. They will assume the shape of least surface area possible containing a given volume." https://lnkd.in/d5zN4He View in LinkedIn

SNACK FOOD NATION. "America has become a snack food nation. More than ever, "meals" are being consumed behind the wheel of a car ... "Dashboard dining". http://www.newsweek.com/bring-junk-food-161601 View in LinkedIn

GEOMETRY OF SOAP BUBBLES. "If a soap film does not contain any bubbles, it can be called a minimal surface. A minimal surface is characterized by having a total curvature equal to zero in every point. This means that for all points on the surface, if the surface is curving with a certain amount in one direction, at the same point the surface will also have to curve with minus the same amount in the normal direction." https://lnkd.in/dirhQBH View in LinkedIn

TOBACCO LEADS. "Despite the huge growth in junk food sales, the three biggest suppliers to Australian supermarkets are British American Tobacco, Philip Morris and Imperial Tobacco Australia, which provide a combined $8.4 billion of annual revenue. That dwarfs the annual contribution of multinationals such as Nestle ($2 billion), Coca-Cola Amatil ($2 billion) and Unilever ($1.5 billion)." https://lnkd.in/dryJsJv View in LinkedIn

CRITICAL MICELLE CONCENTRATION. "When there are too many surfactant molecules for the molecules to be comfortably spaced, they collect in balls called micelles with their water-hating end in the center and the water-loving end on the outside ... As more water is added, there will be a point where there is just enough water so that there will be no more micelles and the surfactant molecules are tightly packed." https://lnkd.in/dYvt3pv View in LinkedIn

"A SOAP BUBBLE is a very thin sheet of water sandwiched between two layers of soap molecules. The film of soapy water surrounds a bubble of air. Soap molecules have one end that repels water, and one that attracts it, and these molecules move to the inner and outer surfaces, thrusting their water-repelling ends out into the air, and their "heads" inwards." https://lnkd.in/dAKy6VD View in LinkedIn

Most people inside soap bubble:193; largest bubble wall: 156 ft; longest soap bubble: 105 ft; largest free floating soap bubble: 20.65 cubic meters; longest lasting soap bubble: 108 days; largest object inside a soap bubble: a truck. https://lnkd.in/di9yQ6x View in LinkedIn
