Double Bubble

Double bubble theorem

In the mathematical theory of minimal surfaces, the double bubble theorem 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 120° on a common circle. The double bubble theorem was formulated and thought to be true in the 19th century, and became a "serious focus of research" by 1989, but was not proven until 2002.

Double bubble (radiology)

In radiology, the double bubble sign is a feature of pediatric imaging seen on radiographs or prenatal ultrasound in which two air filled bubbles are seen in the abdomen, representing two discontiguous loops of bowel in a proximal, or 'high,' small bowel obstruction. The finding is typically pathologic, and implies either duodenal atresia, duodenal web, annular pancreas, or on occasion midgut volvulus, a distinction that requires close clinical correlation and, in most cases, surgical intervention.

Dubble Bubble

Dubble Bubble is an American brand of fruit-flavored, usually pink-colored, bubble gum invented by Walter Diemer, an accountant at Philadelphia-based Fleer Chewing Gum Company in 1928. One of Diemer's hobbies was concocting recipes for chewing gum based on the original Fleer ingredients. Though founder Frank H. Fleer had come up with his own bubble gum recipe under the name Blibber-Blubber in 1906, it was shelved due to its being too sticky and breaking apart too easily. It would be another 20 years until Diemer would use the original idea as inspiration for his invention.
