- Edison screw (Wikipedia)
Edison screw (ES) is a standard lightbulb socket for electric light bulbs. It was developed by Thomas Edison (1847–1931), patented in 1881, and was licensed in 1909 under General Electric’s Mazda trademark. The bulbs have right-hand threaded metal bases (caps) which screw into matching threaded sockets (lamp holders). For bulbs powered by AC current, the thread is generally connected to neutral and the contact on the bottom tip of the base is connected to the “live” phase.
- Hippie (Wikipedia)
A hippie, also spelled hippy, especially in British English, is someone associated with the counterculture of the 1960s, originally a youth movement that began in the United States during or around 1964 and spread to different countries around the world. The word hippie came from hipster and was used to describe beatniks who moved into New York City’s Greenwich Village, in San Francisco’s Haight-Ashbury district, and Chicago’s Old Town community. The term hippie was used in print by San Francisco writer Michael Fallon, helping popularize use of the term in the media, although the tag was seen elsewhere earlier.
