Serbian Americans
Serbian Americans () or American Serbs (), are Americans of Serbs, ethnic Serb ancestry. As of 2023, there were slightly more than 181,000 American citizens who identified as having Serb ancestry. However, the number may be significantly higher, as there were some 290,000 additional people who identified as Yugoslavs living in the United States. The group includes Serbian Americans living in the United States for one or several generations, dual Serbian–American citizens, or any other Serbian Americans who consider themselves to be affiliated with both cultures or countries. History One of the first Serb immigrants to the United States was the settler George Fisher (settler), George Fisher, who arrived in Philadelphia in 1815, moved to Mexico, fought in the Texan Revolution, and became a judge in California. Another notable early Serb in America was Basil Rosevic, who founded a shipping company, the Trans-Oceanic Ship Lines, around the year 1800. In the early 1800s, many Se ...

Turntables
A phonograph, later called a gramophone, and since the 1940s a record player, or more recently a turntable, is a device for the mechanical and analogue reproduction of sound. The sound vibration Waveform, waveforms are recorded as corresponding physical deviations of a helical or spiral groove engraved, etched, incised, or impressed into the surface of a rotating cylinder or disc, called a ''Phonograph record, record''. To recreate the sound, the surface is similarly rotated while a playback #Stylus, stylus traces the groove and is therefore vibrated by it, faintly reproducing the recorded sound. In early acoustic phonographs, the stylus vibrated a Diaphragm (acoustics), diaphragm that produced sound waves coupled to the open air through a flaring Horn loudspeaker, horn, or directly to the listener's ears through stethoscope-type earphones. The phonograph was invented in 1877 by Thomas Edison; its use would rise the following year. Alexander Graham Bell's Volta Laboratory an ...

Vacuum Tubes
A vacuum tube, electron tube, thermionic valve (British usage), or tube (North America) is a device that controls electric current flow in a high vacuum between electrodes to which an electric voltage, potential difference has been applied. It takes the form of an evacuated tubular envelope of glass or sometimes metal containing electrodes connected to external connection pins. The type known as a thermionic tube or thermionic valve utilizes thermionic emission of electrons from a hot cathode for fundamental Electronics, electronic functions such as signal amplifier, amplification and current Rectifier, rectification. Non-thermionic types such as vacuum phototubes achieve electron emission through the photoelectric effect, and are used for such purposes as the detection of light and measurement of its intensity. In both types the electrons are accelerated from the cathode to the anode by the electric field in the tube. The first, and simplest, vacuum tube, the diode or Flem ...
