- The Greatest Generation, also known as the G.I. Generation and the World War II Generation, is the demographic cohort following the Lost Generation and preceding the Silent Generation. The social generation is generally defined as people born from 1901 to 1927. They were shaped by the Great Depression and were the primary generation composing the enlisted forces in World War II. Most people of the Greatest Generation are the parents of the Silent Generation and Baby Boomers, and, in turn, are the children of the Lost Generation.
- Homemade liquid nitrogen generator using Joule Thomson Throttling (homemadeliquidnitrogen.com)
I determined that there was no good tutorial on how the average person can liquefy nitrogen or air. A few references to cryocoolers, which use an internal helium Stirling engine to create a cold head exist, and I even saw one person use this as a means to liquefy nitrogen, allowing the gas to condenses as it passes over the head. This method is cheating because it relies on a self-contained refrigeration unit. I wanted to do this using regenerative cooling just like Carl Linde back in 1895.

The Silent Generation, also known as the Traditionalist Generation, is the Western demographic cohort following the Greatest Generation and preceding the baby boomers. The generation is generally defined as people born from 1928 to 1945. By this definition and U.S. Census data, there were 23 million Silents in the United States as of 2019.
- Lost Generation (Wikipedia)
The Lost Generation is the demographic cohort that reached early adulthood during World War I, and preceded the Greatest Generation. The social generation is generally defined as people born from 1883 to 1900, coming of age in either the 1900s or the 1910s. The term is also particularly used to refer to a group of American expatriate writers living in Paris during the 1920s. Gertrude Stein is credited with coining the term, and it was subsequently popularised by Ernest Hemingway, who used it in the epigraph for his 1926 novel The Sun Also Rises: “You are all a lost generation.” “Lost” in this context refers to the “disoriented, wandering, directionless” spirit of many of the war’s survivors in the early postwar period.
