A bubble chamber is a vessel filled with a superheated transparent liquid (most often liquid hydrogen) used to detect electrically charged particles moving through it. It was invented in 1952 by Donald A. Glaser, [1] for which he was awarded the 1960 Nobel Prize in Physics. [2] Supposedly, Glaser was inspired by the bubbles in a glass of beer ...
Tracer-gas leak testing. A tracer-gas leak testing method is a nondestructive testing method that detects gas leaks. A variety of methods with different sensitivities exist. Tracer-gas leak testing is used in the petrochemical industry, the automotive industry, the construction industry [1] and in the manufacture of semiconductors, among other ...
Cavitation damage evident on the propeller of a personal watercraft. Cavitation in fluid mechanics and engineering normally refers to the phenomenon in which the static pressure of a liquid reduces to below the liquid's vapour pressure, leading to the formation of small vapor-filled cavities in the liquid. [ 1]
Sureshot - gives you an aiming reitcule active for three turns that ensures your shot goes exactly where you want it to go. BubbleBubble - turns all touching bubbles into the same color. Hotfoot ...
A spirit level, bubble level, or simply a level, is an instrument designed to indicate whether a surface is horizontal (level) or vertical ( plumb ). Two basic designs exist: tubular (or linear) and bull's eye (or circular ). Different types of spirit levels may be used by carpenters, stonemasons, bricklayers, other building trades workers ...
One of the useful methods to determine the dynamic surface tension is measuring the "maximum bubble pressure method" or, simply, bubble pressure method. [1] [2] Bubble pressure tensiometer produces gas bubbles (ex. air) at constant rate and blows them through a capillary which is submerged in the sample liquid and its radius is already known ...
The Hardest Logic Puzzle Ever is a logic puzzle so called by American philosopher and logician George Boolos and published in The Harvard Review of Philosophy in 1996. [1] [2] Boolos' article includes multiple ways of solving the problem. A translation in Italian was published earlier in the newspaper La Repubblica, under the title L ...
Bubble (physics) Air bubbles rising from a scuba diver in water. A soap bubble floating in the air. A bubble is a globule of a gas substance in a liquid. In the opposite case, a globule of a liquid in a gas, is called a drop. [1] Due to the Marangoni effect, bubbles may remain intact when they reach the surface of the immersive substance.
