Poktanju

Poktanju is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Poktanju rather than just read about it. In short: Poktanju (Korean: 폭탄주; lit. 'bomb liquor or bomb shot') is a cocktail that is made by mixing soju or whiskey and beer. A poktanju consists of a shot glass of soju or whiskey dropped into a pint of beer; it is drunk quickly.

Key takeaways

  • Poktanju belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Poktanju to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Poktanju from memory before moving on to harder problems.

Reference excerpt

Poktanju (Korean: 폭탄주; lit. 'bomb liquor or bomb shot') is a cocktail that is made by mixing soju or whiskey and beer. A poktanju consists of a shot glass of soju or whiskey dropped into a pint of beer; it is drunk quickly. It is considered to be a ritual drinking activity among office workers, friends, and colleagues. Other possible names for poktanju are boilermaker, bomb shot, bomb drink or somaek.

Korean society and drinking culture In Korea, the act of partaking in drinking is the equivalent of socializing over dinner. Many Koreans view drinking as the quickest way to solidify bonds between family members, friends, and colleagues. "According to a 2013 survey...conducted in collaboration with the Korea Alcohol and Liquor Industry Association, a large majority of Korean people (71.8 percent) regard drinking as a necessary element of social life in Korea, particularly significant for men (65.8 percent)". In a study to identify behaviors and the culture of drinking alcohol in Korean People it was found that most behaviors were in the domain of leisure time. "Drinking for two or more times a month and binge drinking were mainly concentrated in five occasions types: going out with friends (44.2%), going out with colleague (34.2%), drinking at home or friend's home with friends (32.9%), drinking at home alone (29.3%), and drinking with meals at home (27.5%)". Social gatherings including alcohol usually involve participants becoming exceedingly drunk. Ritual Drinking, such as the poktanju, has been integral to the drinking culture of Korea. Since many Koreans feel being drunk is necessary in order to be openly honest with the individuals they are socializing with, poktanju became the cheap, ideal alternative to expensive drinks like whiskey, allowing individuals to become drunk inexpensively.

Rite of passage Poktanju is consumed in the traditional Korean "bottoms up style" often referred to as "one shot". The consumer downs the cocktail quickly "then shakes the empty glass with the shot still inside to make a ringing sound, followed by applause of other drinking partners, and it is passed to the next person." Poktanju, or the "bomb-drink" came about due to social meetings resulting in heavy drinking. "As its name suggests, its main goal is to bombard the drinker with a heavy dose of alcohol until he or she nearly passes out". "A foreigner traveling in Korea and socializing with the locals is likely to be bombarded with such cocktails, which have long been a hallmark of the Korean drinking culture". In March when universities welcome new students, welcoming ceremonies are conducted. "The welcoming ceremonies usually involve binge-drinking events, which generally take the form of all-night sessions in a bar downing boilermaker "bombs". In the military, "Poktanju symbolized power". "The profiles of those who became a high-ranking position or a head of a power organization or such candidates used to include how much they can drink it". "A person who can drink dozens of glasses of alcohol was considered a broad-minded big man".

Origins The origins of poktanju begin first with the origins of soju, the primary ingredient in Korean bomb shot. "Soju is distilled from rice, barley, and koji (a cultured grain), and cheaper brands are made from sweet potatoes". "Soju originated in 14th century Goryeo, when Mongol invaders led by Genghis Khan introduced the Levantine distilling technique from Arabia to the Korean Peninsula". Over time, Koreans learned to distill soju from rice and other grains and eventually we have the popular distilled rice wine that exists today. There are three theories as to how poktanju originally became a cultural phenomenon in Korea, though the agreeance between the theories is that it originated sometime between the 1960's and the 1980's. The first theory is that poktanju emerged when binge drinking became a trend in Korea amongst salaried workers. "Amid rapid economic growth, salaried workers were forced to work hard and found no way to relieve their mounting stress other than heavy drinking"; poktanju became the inexpensive way for workers to bombard their senses and binge on alcohol. The second theory of the origins of poktanju are that it began in the Korean military. "It is believed that the military introduced poktanju to Korean society first. Portal websites also say soldiers who studied in the U.S. in the 1960s and 70s first introduced it to Korea". The third theory is that the "current style of poktanju ― beer with a shot of whisky ― made its Korean debut in the early 1980s, at a meeting between prosecutors, policemen and journalists in Chuncheon, Gangwon province".

Worked examples

Example 1 — a first encounter with Poktanju

Start with the simplest possible case. Write down what Poktanju claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Poktanju before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Poktanju ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Poktanju

In research
Poktanju appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Poktanju in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Poktanju is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drinking culture, South Korean alcoholic beverages, Two-ingredient cocktails, so understanding it makes those chapters shorter.
In everyday life
Look for Poktanju outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
