SINGULARITIES. "A singularity is the point at which any given mathematical object -- such as an equation or surface -- breaks down and "explodes", no longer defined. According to a new study, identifying a type of curve in a film of soap can help predict where singularities are likely to occur in other films of soap -- which, in turn, could help researchers understand real-world natural singularities." https://lnkd.in/dX6zRsR 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

SOAP BUBBLES INFORM EINSTEIN. "The structure of the equations obeyed by minimal surfaces or soap bubbles is eerily similar to that of Einstein's equations, the centerpiece of his general theory of relativity. Results from the theory of minimal surfaces give information that is important for analyzing solutions to Einstein's equations, and vice versa." https://lnkd.in/dJxmSGq 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

STASIS. "Why does the bubble not grow over time, if the pressure inside is larger than the pressure outside? We have to take another pressure into account: The pressure from the soap film itself, towards the centre of the bubble. As a result of surface tension the soap film will minimize its surface area by making the bubble as small as possible. Hence the bubble does not grow because there is a balance between the pressure inside the bubble and the pressure from the soap film plus the air pressure from the outside." https://lnkd.in/dVnXykS 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

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
