soap bubble

adjective Referring to dilated, smooth-contoured, cyst-like or ballooned—occasionally loculated—space(s); formally, physaliferous spaces.

Imaging-bone
Referring to an expansile, often eccentric, vaguely trabeculated space with a thin, sclerotic, sharply defined margin, which is characteristic of an aneurysmal bone cyst (ABC); other bone lesions with soap-bubble-like expansions include giant cell tumour, osteosarcoma, solitary bone cyst, non-ossifying fibroma, fibrous dysplasia, metastatic malignancy, chondromyxoid fibroma, “combined” stage of Paget’s disease of bone, expansile mandibular lesions of cherubism and metastatic renal cell carcinoma. Radiologic findings of “punched-out” lytic lesions of bone (e.g., in myeloma, angiosarcoma, ameloblastoma) have been described as soap-bubble-like.
 
Imaging-GI
A descriptive term for the widely open air spaces seen in an abdominal plain film in a gas-producing bacterial abscess.
 
Microbiology
A descriptive term for the light microscopic appearance of Pneumocystis jiroveci (formerly P carinii) in tissue.

Neuropathology
A descriptive term for the light microscopic appearance of Cryptococcus neoformans when stained with India ink, which is most prominent in the Virchow-Robin space.
 
Pathology
A descriptive term for the physaliferous cells of chordomas, or epithelial cells in hyperplastic thyroid epithelium.

Fluid dynamics researchers have had some doubts about soap films as a model for two-dimensional turbulence, Sommerer says, because they suspected that such films might have significant flow in the third dimension, evident as thickness variations.
This sculpture represents the latest turn in an exploration that started more than two centuries ago with observations of soap films in nature.
Together, the pair of crystal images is the equivalent of a soap bubble next to a soap film on a wire frame.
In other words, they looked at the analog of a soap film on a wire frame.
Over the years, mathematicians have extended this concept of a "minimal surface" to include forms that no soap film can take on.
Her current work with sculptor Ann Hamilton is filled with giant soap films, hidden cameras, and projections--and the rest is mystery until its debut this summer at the American Dance Festival (see story).
It allows introduction of concepts such as atomic transitions, black body radiation, the Boltzmann distribution, molecular orbitals, the Fermi distribution, band theory, interference, soaps and soap films.
In a very interesting experiment, Isenberg (1992) used a demonstration of soap films and soap bubbles to find this angle.
For instance, in the late 1990s, Hutzler and his Trinity colleagues discovered that a vertical seam at which several soap films meet would gulp down a spherical droplet of soap solution and transform it, temporarily, into a football-shaped antibubble that descends while trapped in the seam.
Also, giant soap films will be created on ropes hung from the fly-loft, with lights then projected onto them.
For soap films in air, he predicted that waves would arise unbidden from the thermal jiggling of molecules or atoms in the film and then amplify at a favored frequency until the waves broke through the surfaces.
