The Symbolic Optimal Assembly Program (SOAP) is an assembler for the IBM 650 Magnetic Drum Data-Processing Machine, an early computer first used in 1954. It was developed by Stan Poley at the IBM Thomas J. Watson Research Center . [ 1 ]
The Coles 4038 is a ribbon microphone produced by Coles Electroacoustics. The microphone was designed and patented by the BBC in the 1950s [1] and was originally known as the STC 4038. [2] The sound of the microphone has been described as "British" with a "BBC politeness", [3] and its appearance has been likened to that of a waffle iron. [4]
Polymeric micelles have a much lower critical micellar concentration (CMC) than soap (0.0001 to 0.001 mol/L) or surfactant micelles, but are nevertheless at equilibrium with isolated macromolecules called unimers. Therefore, micelle formation and stability are concentration-dependent. [3]
Shure Brothers microphone, model 55S, multi-impedance "Small Unidyne" dynamic from 1951. A microphone, colloquially called a mic (/ m aɪ k /), [1] or mike, [a] is a transducer that converts sound into an electrical signal.

Microphones can be thought of as speakers in reverse. The sound waves strike the thin diaphragm, causing it to vibrate. [1] Microphone diaphragms, unlike speaker diaphragms, tend to be thin and flexible, since they need to absorb as much sound as possible. In a condenser microphone, the diaphragm is placed in front of a plate and is charged. [2]
Shure SM7B microphone used in an interview with Marius Bear The Shure SM7 is a professional cardioid dynamic microphone , commonly used in broadcasting applications since 1973. Designed by Shure , it has been described as an "iconic" industry standard microphone for its focused, directional sound and its widespread adoption in radio, television ...
There were later models of the device, some with more complex internal structure (the center post under the membrane attached to a helix, probably to increase the Q factor). Maximizing the Q factor was one of the engineering priorities, as this allowed higher selectivity to the illuminating signal frequency, and therefore increased operating ...
