Vinyl records have made a resurgence in the past few years. They come in three standard sizes: 7'', 10'', and 12''. They are also meant to be played at various rotations per minute (rpm): usually 331⁄3, 45, or 78. Though you can always play a record at a slower or faster speed than intended, for interesting effect. The history of audio recording goes back to the 1850s, with the invention of the Phonautograph in 1857. It inscribed the waveforms linearly on paper or glass. However, at the time there was no way of playing back the sound. In 2008 some of the sheets were scanned and digitally reconstructed into audio files, allowing the recordings to be reheard after almost 150 years. In 1877 Edison unveiled his Phonograph, which inscribed audio on a wax cylinder. It allowed playback and reproducibility, but the cylinders were degraded significantly in each instance. Emile Berliner invented the Gramophone in 1887, which not only improved the quality and reproducibility, but was also the first to use disc shaped records. Discs in various form would become the standard form of data storage for the next century.
Bonus:
The word whiskey comes from the Irish/Scottish words Uisce Beatha/Uisge Beatha, which means 'water of life'.
