BUBBLE TECHNOLOGY. "The bubble-based technology creates bubbles with a specified size and frequency, fills them with an opaque fog that is optionally scented, controls their route, tracks their location and projects an image onto them." https://lnkd.in/d4JyFBZ View in LinkedIn

INTERFERENCE. "The resulting colors are a combination of the colors that do not undergo destructive interference and their degrees of constructive interference. Blue-green colors dominate in thicker films and yellow hues in thinner films. Eventually, the film becomes too thin to create interference of visible wavelengths, as all wavelengths are cancelled out. At this point the bubble appears colorless. Against a black background the bubble surface could appear black." https://lnkd.in/dAKy6VD View in LinkedIn

LIGHT INTERFERENCE PATTERNS. "When an incoming ray of light strikes the outer surface of a bubble, part of the light ray is reflected immediately, while the other part is transmitted into the soap film. After reaching the inner surface of the film, this transmitted light ray is reflected back toward the outer surface. When it leaves the bubble, it travels in the same direction as the ray that was immediately reflected and is, therefore, parallel to that ray." https://lnkd.in/dAKy6VD View in LinkedIn

SOAP BUBBLES IRIDESCENCE. A brilliant set of observations on the humble soap bubble. Iridescence and multiple hues, reflected images, mirror ball reflections, inner and outer reflections, and reflections and shadow of soap bubbles. https://lnkd.in/dDX_RSd View in LinkedIn

ARCHITECTURAL BUBBLE MIMICRY. "Due to these qualities soap bubbles films have been used with practical problem solving application. Structural engineer Frei Otto used soap bubble films to determine the geometry of a sheet of least surface area that spreads between several points, and translated this geometry into revolutionary tensile roof structures. A famous example is his West German Pavilion at Expo 67 in Montreal." https://lnkd.in/d5zN4He View in LinkedIn

FOAMS. "Physical effects drive these interfaces around, and the complexity has to do with the fact that the mechanics occur on a wide range of time and space scales ... It's challenging to build numerical models that allow you to couple these wildly different scales together so that they talk to each other in a way that's accurate and physically reasonable." https://lnkd.in/dGWCSXR View in LinkedIn

HEXAGONAL BUBBLES. "When two bubbles meet, they will merge walls to minimize their surface area. If bubbles that are the same size meet, then the wall that separates them will be flat. If bubbles that are different sizes meet, then the smaller bubble will bulge into the large bubble. If bubbles that are different sizes meet, then the smaller bubble will bulge into the large bubble. Bubbles meet to form walls at an angle of 120°. If enough bubbles meet, the cells will form hexagons." https://lnkd.in/d7g3Avs View in LinkedIn

MULTIPLE BUBBLE PROBLEMS. "Over the past few decades, mathematicians have become increasingly interested in “multiple bubble problems.” These problems ask which figure among all those that separately contain a given number of volumes has the least surface area." http://jur.byu.edu/?p=3684 View in LinkedIn

DOUBLE BUBBLE PROBLEM. "In the mathematical theory of minimal surfaces, the double bubble conjecture states that the shape that encloses and separates two given volumes and has the minimum possible surface area is a standard double bubble — three spherical surfaces meeting at angles of 2π/3 on a common circle." https://lnkd.in/dnPcbKg View in LinkedIn

DOUBLE BUBBLE PROBLEM. "In the mathematical theory of minimal surfaces, the double bubble conjecture states that the shape that encloses and separates two given volumes and has the minimum possible surface area is a standard double bubble — three spherical surfaces meeting at angles of 2π/3 on a common circle. It is now a theorem, as a proof of it was published in 2002." https://lnkd.in/dnPcbKg View in LinkedIn
