Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone , which uses a coil of wire suspended in a magnetic field; the condenser microphone , which uses the vibrating diaphragm as a capacitor plate; and ...
Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together. [6] The distinction may blur as science becomes increasingly collaborative. [7] A distinction is drawn between a discovery and an invention, as discussed for example by Bolesław Prus. [8]
