- Going Postal (Wikipedia)
Going Postal is a fantasy novel by British writer Terry Pratchett, the 33rd book in his Discworld series, released in the United Kingdom on 25 September 2004. Unlike most of Pratchett’s Discworld novels, Going Postal is divided into chapters, a feature previously seen only in Pratchett’s children’s books and the Science of Discworld series. These chapters begin with a synopsis of philosophical themes, in a similar manner to some Victorian novels and, notably, to Jules Verne stories. The title refers to both the contents of the novel, as well as to the term ‘going postal’.
- Cathode ray tube (Wikipedia)
A cathode ray tube (CRT) is a vacuum tube containing one or more electron guns, which emit electron beams, which are directed and controlled to display images on a phosphorescent screen. The images may represent electrical waveforms on an oscilloscope, a frame of video on an analog television set (TV), digital raster graphics on a computer monitor, or other phenomena like radar targets. A CRT in a TV is commonly called a picture tube. CRTs have also been used as memory devices, in which case the screen is not intended to be visible to an observer. The term cathode ray was used to describe electron beams when they were first discovered, before it was understood that what was emitted from the cathode was a beam of electrons.
