Limelight (also known as Drummond light or calcium light) [1] is a non-electric type of stage lighting that was once used in theatres and music halls. An intense illumination is created when a flame fed by oxygen and hydrogen is directed at a cylinder of quicklime ( calcium oxide ), [ 2 ] due to a combination of incandescence and ...

Optical tweezers are used in biology and medicine (for example to grab and hold a single bacterium, a cell like a sperm cell or a blood cell, or a molecule like DNA), nanoengineering and nanochemistry (to study and build materials from single molecules), quantum optics and quantum optomechanics (to study the interaction of single particles with ...
In its simplest form, it consists of two electrodes in a cell held at low pressure (0.1–10 torr; about 1/10000 to 1/100 of atmospheric pressure). A low pressure is used to increase the mean free path ; for a fixed electric field, a longer mean free path allows a charged particle to gain more energy before colliding with another particle.
Helical xenon flashtube emitting greybody radiation as white light. (Animated version below.) A flashtube (flashlamp) produces an electrostatic discharge with an extremely intense, incoherent, full-spectrum white light for a very short time. A flashtube is a glass tube with an electrode at each end and is filled with a gas that, when triggered ...
