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

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

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

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

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

"SONOLUMINESCENCE arises from acoustic cavitation – the formation, growth and implosion of small gas bubbles in a liquid blasted with sound waves above 18,000 cycles per second. The collapse of these bubbles generates intense local heating. "Nobody has been able to measure the temperature inside a single collapsing bubble before. The temperature we measured – about 20,000 degrees Kelvin – is four times hotter than the surface of our sun." https://lnkd.in/dvGA4ee View in LinkedIn

FROZEN BUBBLES. "Remarkably, soap bubbles can be blown in very cold temperatures, freeze and remain intact if they are strong enough. Once frozen they would each have unique crystalline patterns and shapes, some would crack like an egg and others would deflate." https://lnkd.in/d6yTfAU View in LinkedIn

VESTIGIAL METABOLISM. "Once obesity is established, however, body weight seems to become biologically 'stamped in' and defended. The human body, evolved to endure through periods of food scarcity, has adapted a host of methods to ensure that lost weight will be restored." https://lnkd.in/d9duDay View in LinkedIn

THE HUMAN BODY "will respond to weight loss by powering down its use of calories as fuel, pumping out hormones to increase hunger, boosting fat storage capacity, and tricking the brain to demand overconsumption." https://lnkd.in/d9duDay View in LinkedIn

IN REMISSION. "Few individuals ever truly recover from obesity ... Those that do ... "still have 'obesity in remission,' and are biologically very different from individuals of the same age, sex and body weight who never had obesity." They are constantly at war with their bodies' efforts to return to their highest sustained weight." https://lnkd.in/d9duDay View in LinkedIn
