Gakgung

Gakgung 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 Gakgung rather than just read about it. In short: The gakgung (Korean: 각궁; Hanja: 角弓), also called Korean bow, is a water buffalo horn-based composite reflex bow, standardized centuries ago from a variety of similar weapons in earlier use. Due to its long use by Koreans, it is also known as Guk Gung (Korean: 국궁 hanja: 國弓, or national bow).

Key takeaways

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

Reference excerpt

The gakgung (Korean: 각궁; Hanja: 角弓), also called Korean bow, is a water buffalo horn-based composite reflex bow, standardized centuries ago from a variety of similar weapons in earlier use. Due to its long use by Koreans, it is also known as Guk Gung (Korean: 국궁 hanja: 國弓, or national bow). The Korean bow utilizes a thumb draw and therefore employing the use of a thumb ring is quite common. The Korean thumb ring is somewhat different from the Manchu, Mongol, or the Turkic thumb rings, as it comes in two styles, male and female. Male thumb rings are shaped with a small protrusion that sticks out that the bowstring hooks behind (similar to a release aid), while the female thumb ring simply covers the front joint of the thumb as protection from getting blisters (pulling heavy bows repetitively with only the thumb can easily cause blisters to form on the pad of the thumb). Gungsul, Korean: 궁술, hanja: 弓術, sometimes also romanized as goong sool, literally means "techniques of the bow" or "skill with the bow". It is also referred to as Korean traditional archery. However, goong sool is not a desirable expression. Gungdo, Korean: 궁도, hanja: 弓道, "way of the bow" is another epithet for traditional Korean archery, as used by Koreans.

History of military origin and usage

The reflex bow had been the most important weapon for Koreans in wars with Chinese dynasties and nomadic peoples, recorded from the 1st century BC. Legend says the first king and founder of the Goguryeo, Go Jumong, was a master of archery, able to catch five flies with one arrow. Bak Hyeokgeose, the first king of the Silla, was also said to be a skilled archer. The ancient Chinese gave the people of the East (Shandong Peninsula, Huai river basin, Jianghuai, Manchuria, the Korean Peninsula, Japanese archipelago, and eastern Siberia) the name of Dongyi (東夷) being a combination of the two characters for "large" (大) and "bow" (弓). However, it also need to be noted that the term was widely applied by the Chinese to note any foreign tribes in the east associated with large bows. Yi Sŏng-gye, the founding king of Joseon was known to have been a master archer. In a battle against Japanese pirates, Sŏng-gye, assisted by Yi Bangsil, killed the young samurai commander "Agibaldo" with two successive arrows, one arrow knocking out his helmet, with the second arrow entering his mouth. In his letter to General Ch'oe Yŏng, Sŏng-gye lists as one of five reasons not to invade Ming China as during the monsoon season, glue holding together the composite bow weakens, reducing the effectiveness of the bow. The founding of Joseon dynasty saw the retention of the composite bow as the mainstay of the Joseon military. Archery was the main martial event tested during the military portion of the national service exam held annually from 1392 to 1894. Under Joseon, archery reached its zenith, resulting in the invention of pyeonjeon, which saw great service against the Japanese in 1592 and against the Manchus in early 1600s. Until the Imjin wars, archery was the main long-range weapon system. During those wars, the tactical superiority of the matchlock-ignited arquebus became apparent, despite its slow rate of fire and susceptibility to wet weather. However, it was the gakgung, referred to as the "half bow" by the Japanese, that halted the Japanese at the Battle of Haengju as well as at the Battle of Ulsan. Although Joseon adopted the arquebus during the Imjin War, the gakgung retained its position of importance in the military until the reforms of 1894. Under King Hyojong's military reforms, an attempt was made to revive horse archery as a significant element of the military. It was also practiced for pleasure and for health, and many young males — including the king — and some females would spend their free time practicing it.

Transition to recreational sport

In 1899, the visiting Prince Heinrich of Prussia expressed his astonishment to Emperor Gojong at a traditional archery demonstration. The Prince, hailing from a militarized Prussian culture, sought out demonstrations of Korean martial arts, and Archery was the most impressive among the arts demonstrated. He was familiar with Turkish and Hungarian Archery of Europe, which were similar to Korean Archery. Prince Heinrich suggested making the art into a national sport. The emperor, convinced by the Prince, decreed "let people enjoy archery to develop their physical strength" and established an archery club. In the subsequent standardization of Korean archery, the nature of the bow and the arrow was standardized, as was the range of the targets. Korean traditional archery now uses one specific type of composite bow, bamboo arrows, and a standard target at a standard distance of 120 bo (about 145 m or 160 yards). Korean Archery as a sport developed under the Japanese Occupation, its textbook, "Joseon eui Goongdo" being published in 1920. Tradition says that a noted general of the Joseon Dynasty settled in Yecheon about 300 years ago, and handed down his expertise and knowledge. "Today, it is estimated that bowyers from Yecheon and its environs produce approximately 70% of Korea's traditional horn composite bows ...Yecheon has produced numerous Olympic medalists and world champion archers". The city has the Jinho International Archery Field.

Worked examples

Example 1 — a first encounter with Gakgung

Start with the simplest possible case. Write down what Gakgung 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 Gakgung 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 Gakgung 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 Gakgung

In research
Gakgung 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 Gakgung 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
Gakgung is common in secondary-school and first-year university syllabi. It links to neighbouring topics Bows (archery), Korean inventions, Medieval archery, so understanding it makes those chapters shorter.
In everyday life
Look for Gakgung 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.

Why does Gakgung matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Gakgung?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
