William P. Parker is an American artist, scientist, and entrepreneur, best known for inventing the modern design of the plasma globe. [1] The invention occurred in 1971, when Parker was working as a student in a physics laboratory at the Massachusetts Institute of Technology and accidentally filled a test chamber to a greater-than-usual pressure with ionized neon and argon. [2] Three years later, Parker was artist-in-residence at the Exploratorium in San Francisco and created two installations using this technology, entitled Quiet Lightning and AM Lightning. [2] [3] [4] [5]
Parker has also exhibited at the MIT Museum, [6] [7] [8] [9] the New York Hall of Science, [10] and the Housatonic Museum at Housatonic Community College in Bridgeport, Connecticut. [11] He was the youngest Fellow at the MIT Center for Advanced Visual Studies. [12] Plasma globes based on his designs were commercially popular in the 1980s [13] [14] and “are found in nearly every science museum in the world". [15]
In the 1980s, Parker founded Diffraction Ltd, [15] [16] a defense electro-optics developer that was purchased by the O'Gara Group in 2005. [17] and in 2006 he spun off another company, Creative MicroSystems, focusing on microfluidics. [16] He maintains a studio in Waitsfield, Vermont, and in 2008 he was elected to the Waitsfield select board. [18] [19]
Holography is a technique that enables a wavefront to be recorded and later reconstructed. It is best known as a method of generating real three-dimensional images, but also has a wide range of other applications. In principle, it is possible to make a hologram for any type of wave.
Sir Joseph Wilson Swan FRS was an English physicist, chemist, and inventor. He is known as an independent early developer of a successful incandescent light bulb, and is the person responsible for developing and supplying the first incandescent lights used to illuminate homes and public buildings, including the Savoy Theatre, London, in 1881.
A plasma display panel (PDP) is a type of flat panel display that uses small cells containing plasma: ionized gas that responds to electric fields. Plasma televisions were the first large flat panel displays to be released to the public.
A neon lamp is a miniature gas-discharge lamp. The lamp typically consists of a small glass capsule that contains a mixture of neon and other gases at a low pressure and two electrodes. When sufficient voltage is applied and sufficient current is supplied between the electrodes, the lamp produces an orange glow discharge. The glowing portion in the lamp is a thin region near the cathode; the larger and much longer neon signs are also glow discharges, but they use the positive column which is not present in the ordinary neon lamp. Neon glow lamps were widely used as indicator lamps in the displays of electronic instruments and appliances. They are still sometimes used for their electrical simplicity in high-voltage circuits.
A plasma ball, plasma globe, or plasma lamp is a clear glass container filled with a mixture of various noble gases with a high-voltage electrode in the center of the container.
An acoustic mirror is a passive device used to reflect and focus (concentrate) sound waves. Parabolic acoustic mirrors are widely used in parabolic microphones to pick up sound from great distances, employed in surveillance and reporting of outdoor sporting events. Pairs of large parabolic acoustic mirrors which function as "whisper galleries" are displayed in science museums to demonstrate sound focusing.

In April 2015, Somorjai was awarded the American Chemical Society's William H. Nichols Medal.
Neon lighting consists of brightly glowing, electrified glass tubes or bulbs that contain rarefied neon or other gases. Neon lights are a type of cold cathode gas-discharge light. A neon tube is a sealed glass tube with a metal electrode at each end, filled with one of a number of gases at low pressure. A high potential of several thousand volts applied to the electrodes ionizes the gas in the tube, causing it to emit colored light. The color of the light depends on the gas in the tube. Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals are used to produce other colors, such as hydrogen (purple-red), helium, carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or pictures. They are mainly used to make dramatic, multicolored glowing signage for advertising, called neon signs, which were popular from the 1920s to 1960s and again in the 1980s.
A Tiffany lamp is a type of lamp with a camed glass shade designed by Louis Comfort Tiffany or colleagues, and made in his design studio. The glass in the lampshades is put together with the copper-foil technique instead of leaded, the classic technique for stained-glass windows. Tiffany lamps are considered part of the Art Nouveau movement. Considerable numbers of designs were produced from 1893 onwards.
Nova was a high-power laser built at the Lawrence Livermore National Laboratory (LLNL) in California, United States, in 1984 which conducted advanced inertial confinement fusion (ICF) experiments until its dismantling in 1999. Nova was the first ICF experiment built with the intention of reaching "ignition", a chain reaction of nuclear fusion that releases a large amount of energy. Although Nova failed in this goal, the data it generated clearly defined the problem as being mostly a result of Rayleigh–Taylor instability, leading to the design of the National Ignition Facility, Nova's successor. Nova also generated considerable amounts of data on high-density matter physics, regardless of the lack of ignition, which is useful both in fusion power and nuclear weapons research.
In nonlinear optics, filament propagation is propagation of a beam of light through a medium without diffraction. This is possible because the Kerr effect causes an index of refraction change in the medium, resulting in self-focusing of the beam.
The MIT Museum, founded in 1971, is located at the Massachusetts Institute of Technology in Cambridge, Massachusetts. It hosts collections of holography, technology-related artworks, artificial intelligence, architecture, robotics, maritime history, and the history of MIT. Its holography collection of 1800 pieces is the largest in the world, though only a few selections from it are usually exhibited. As of 2023, works by the kinetic artist Arthur Ganson are the largest long-running displays. There is a regular program of temporary special exhibitions, often on the intersections of art and technology.

G. Michael Morris was president of the Optical Society of America in 2002.
Plasma is one of four fundamental states of matter, characterized by the presence of a significant portion of charged particles in any combination of ions or electrons. It is the most abundant form of ordinary matter in the universe, mostly in stars, but also dominating the rarefied intracluster medium and intergalactic medium. Plasma can be artificially generated by heating a neutral gas or subjecting it to a strong electromagnetic field.
Physics outreach encompasses facets of science outreach and physics education, and a variety of activities by schools, research institutes, universities, clubs and institutions such as science museums aimed at broadening the audience for and awareness and understanding of physics. While the general public may sometimes be the focus of such activities, physics outreach often centers on developing and providing resources and making presentations to students, educators in other disciplines, and in some cases researchers within different areas of physics.
