 Coalition for Plasma Science - What is a plasma?
Irving Langmuir, a researcher working to understand electric discharges, was the first to use the term in this way.
During the 1920's Irving Langmuir was studying various types of mercury-vapor discharges, and he noticed similarities in their structure - near the boundaries as well as in the main body of the discharge.
One version [2] of the story has it that the similarity was in carrying particles, while another account [3] speculated that it was in the Greek origin of the term, meaning "to mold," since the glowing discharge usually molded itself to the shape of its container.

 I. Langmuir's Ball Lightning Tube
Then through a momentary interruption of current, the arc gains life and tears itself away from the tube with the writhing motion of a snake, while from a tungsten filament at the base of the tube melted tungsten is sputtered and (Continued on page 255) (cont) bright blue flashes are sent up the vertical stem.
And yet at first glance the apparatus in which these curious phenomena take place seems to differ only in shape from the ordinary two-electrode vacuum tube, and essentially is similar to the argon-filled tungar rectifying bulb.
The ions of a highly ionized gas, such as the electrified atmosphere, recombine on solid particles forming small spheres, the solid particles being retained within the ball by their charges and the electric field being retained at the surface of the ball.
