List of Korean inventions and discoveries

This is a list of Korean inventions and discoveries; Koreans have made contributions to science and technology from ancient to modern times. In the present, South Korea plays an active role in the ongoing Digital Revolution, with one of the largest electronics industries and most innovative economies in the world.[1][2]

Agriculture

The first unambiguously domesticated, cultigen-sized soybean was discovered in Korea at the Mumun-period Daundong site.[3][4]
The first description of a heated greenhouse is from the Sanga Yorok, a treatise on husbandry compiled by a royal physician of the Joseon dynasty of Korea during the 1450s, in its chapter on cultivating vegetables during winter. The treatise contains detailed instructions on constructing a greenhouse that is capable of cultivating vegetables, forcing flowers, and ripening fruit within an artificially heated environment, by utilizing ondol, the traditional Korean underfloor heating system, to maintain heat and humidity; cob walls to insulate heat; and semi-transparent oiled hanji windows to permit light penetration for plant growth and provide protection from the outside environment. The Annals of the Joseon Dynasty confirm that greenhouse-like structures incorporating ondol were constructed to provide heat for mandarin orange trees during the winter of 1438.[5]
The first standardized rain gauge, called the cheugugi, was invented during the reign of Sejong the Great in the Joseon dynasty of Korea.[6][7][8][9][10] The cheugugi was used throughout the country for official purposes. In the 15th century, Korea was the only country to use a quantitative measuring device for the purpose of meteorological observation.[10]
The homi, which dates back to the Bronze Age, is one of the most representative agricultural tools of Korea.[11] Its signature tapered blade was developed during the Later Silla period.[12] In recent times, the homi (known by names such as the "Ho-Mi EZ Digger" and "Korean hand plow")[13][14][15] has gained popularity in the West.[16]

Aquaculture

 
Bangudae petroglyphs
Limestone net sinkers discovered in Korea dating to 27,000 BC are the earliest evidence of fishing by nets and also the oldest fishing implements found to date in the world.[17]
The earliest depictions of whaling have been discovered in Korea at the Neolithic Bangudae site, which may date back to 6000 BC.[18] Bangudae is the earliest evidence for whaling.[19]
The earliest cultivation of gim, an edible seaweed, was started by Kim Yeo-ik (김여익; 金汝瀷) in the middle of the 17th century.[20][21]
  • Pollock farming
In 2016, the National Institute of Fisheries Science of South Korea succeeded in farming Alaska pollock for the first time in the world, allowing the fish to lay eggs a year and 8 months after birth, as opposed to 3 years in the wild.[22][23] Alaska pollock is considered the "national fish" of Korea and is prepared in a number of dishes, including myeongnan-jeot, which was introduced and popularized in Japan as "mentaiko" in the 20th century.[24]

Architecture

 
In the ondol system, heat and smoke from the kitchen stove circulates under the building, warming the floors, then exits through the chimneys.
 
Namhan Mountain Fortress
 
Gyeongcheonsa Pagoda
One of the earliest systems of underfloor heating, dating back 2,500 years, was invented and widely used by Koreans. The Korean ondol heating system was thought to be the oldest of its kind until the recent archaeological discovery of a similar heating system in the Alaskan Aleutian Islands. However, the archaeologist who discovered it agrees with Korean researchers that the two systems developed independently, based on the distance of 5,000 kilometers and the absence of ondol in the areas between them.[25][26][27] Some Korean researchers have explained this phenomenon by hypothesizing that a whale-hunting people from the Korean Peninsula migrated by sea to Alaska during prehistoric times.[28][29][30] Inspired by the Korean ondol hydronic radiant floor heating system, the American architect Frank Lloyd Wright developed and introduced the first "radiant heating system" using hot water pipes.[31][32]
The ancient Silla kingdom created an early refrigeration system called seokbinggo, which were subterranean chambers used to store ice and food.[33][34]
Koreans developed a unique and distinct fortress tradition.[35] Korean fortresses were based on a stone culture and built with stones on natural mountainous terrain; therefore, they are conceptually completely different compared to Chinese fortresses, which were based on an earth culture and built with bricks and stamped earth on flat land.[36][37] Korean fortresses were invented by Goguryeo and spread to Baekje and Silla,[38] and then inherited and further developed by Goryeo and then Joseon.[37] Goguryeo fortress ruins have been found in about 170 sites to date, including in China;[39] one of the most notable among them is Ansi Fortress, which successfully defended against Tang Taizong during the Goguryeo–Tang War.[40][41] Korea, beginning with Goguryeo,[39][42][43] has been called "a country of fortresses";[35][37][44][45] almost 2,400 mountain fortress sites have been found in Korea.[35][37] Korean-style fortresses can also be found in Japan, which were constructed and supervised by immigrants of Baekje origin.[37]
Koreans created a unique and distinct pagoda tradition using stone.[46][47][48] Pagodas were created in India using earth, then in China using wood, which spread to the Three Kingdoms of Korea, and then Japan; however, the pagoda tradition of East Asia diverged, with China creating pagodas using bricks, Korea creating pagodas using stone, and Japan continuing to use wood.[49][50][51][52][53] Korean stone pagodas were first created in Baekje during the early 7th century and then inherited by Later Silla; 90% of the pagodas in Later Silla were made of stone.[49] The stone pagoda tradition was propagated by the great abundance of high quality granite in Korea,[54] which also led to other granite creations such as the Seokguram and Cheomseongdae. Goryeo, a devoutly Buddhist state, also inherited the stone pagoda tradition.[55]

Astronomy

The earliest known constellation patterns in Korea can be found on dolmens dating back to 3000 BC.[56] The Cheonsang Yeolcha Bunyajido is a planisphere inscribed on black marble that was completed in 1395 during the reign of King Taejo; according to its inscription, it is based on a star chart from ancient Goguryeo that was lost during wartime. It is known as the world’s second oldest star chart engraved in stone, after the Chinese Suzhou Star Chart of 1247. However, the Cheonsang Yeolcha Bunyajido's stellar positions indicate an epoch dating back to the first century AD, thus making it the oldest actual representation of the stars in the world.[57]
The Cheomseongdae is the oldest surviving astronomical observatory in Asia,[58][59][60] and possibly the world.[61][62][63] It was constructed in Seorabeol, the capital of Silla, during the reign of Queen Seondeok in the 7th century. Modeled on Baekje's Jeomseongdae, which now exists only in historical records, the Cheomseongdae influenced the construction of a Japanese observatory in 675, and Duke Zhou's observatory in China in 723.[64]

Mathematics

 
Gusuryak by Choi Seok-jeong, published in 1700
The first literature on the Latin square dates back to the monograph Gusuryak (구수략; 九數略) by the Joseon mathematician Choi Seok-jeong (1646–1715),[65] predating Leonhard Euler by at least 67 years.[66][67]
The hexagonal tortoise problem (지수귀문도; 地數龜文圖) was invented by Choi Seok-jeong during the Joseon period.[68]
The Korean mathematician Rimhak Ree discovered and constructed the Ree group in the mathematical field of group theory.
Chisanbop is an abacus-like calculation system using fingers that was invented in Korea in the 1940s and brought to the West in the 1970s.[69]

Writing

Hangul is the world's first featural writing system, wherein the shapes of the letters are not arbitrary, but encode phonological features of the phonemes they represent.[70] The Korean alphabet is unique among the world's writing systems, in that it combines aspects of featural, phonemic, and syllabic representation.[71] Hangul, originally named Hunminjeongeum, was personally created by Sejong the Great[72][73] to promote literacy among the common people.[74]
Predating the creation of Hangul by hundreds of years, Koreans created various phonetic writing systems that were used in conjunction with Hanja, including idu, hyangchal, gugyeol, and gakpil.[75][76][77][78] Some of them may have influenced the development of kana in Japan.[77][79][80]

Printing

 
Jikji, the oldest surviving book printed with movable metal type
Movable metal type was invented in Korea in the early thirteenth century,[81][82][83][84][85] predating Gutenberg's invention in Europe by two centuries[86] and advancing the movable type technology developed in the Song dynasty of China. The first book to be printed with movable metal type is the Prescribed Ritual Texts of the Past and Present in 1234 during the Goryeo period.[87] The earliest surviving book to be printed with movable metal type is the Jikji, dated to 1377.[87][88] The first lead type in the world is the Byeongjinja created in 1436.[89] Metal types were called juja (cast characters), and the Joseon government operated the jujaso bureau, a continuation of Goryeo's seojeogwon, to print books and documents to be distributed to the central and local administrations, village schools, scholars, and officials.[90]
The Jobo, which is discussed in the Annals of the Joseon Dynasty, is possibly the oldest newspaper in the world. Published in 1577, the Jobo was a privately run commercial newspaper, printed daily, that covered a range of topics, including weather, constellations, and current affairs. In 2017, a Korean monk claimed to have discovered an extant copy of the Jobo.[91][92]

Horology

In 1433, the scientist Jang Yeong-sil invented an automatic time-annunciating clepsydra called the Striking Palace Clepsydra under an order from Sejong the Great; the uniqueness of the clock was its capability to announce dual-times automatically with both visual and audible signals.[93] Jang developed a signal conversion technique that made it possible to measure analog time and announce digital time simultaneously as well as to separate the water mechanisms from the ball-operated striking mechanisms.[94] The conversion device was called pangmok, and was placed above the inflow vessel that measured the time, the first device of its kind in the world.[95] Thus, the Striking Palace Clepsydra is the first hydro-mechanically engineered dual-time clock in the history of horology.[96][97]
  • Braille smartwatch
The world's first Braille smartwatch, called the Dot, was developed by a Korean startup company. The Dot features a tactile button display and uses Bluetooth to connect to electronic devices.[98]

Military

Traditional

 
18th century depiction of the geobukseon
Iron plate armor was used by Silla and Gaya beginning in the early 4th century.[99] According to the Gyeongju National Museum, "The armor excavated from historic sites in Gujeongdong is plate armor, consisting of a number of long iron plates vertically linked with one another, a feature that is unique to armor found on the Korean Peninsula."[100]
The "se-chongtong" was a handheld firearm that was developed in 1432 for use against the Jurchens. It measured 13.8cm, weighed 135g, and was held by a handle that worked like pliers that allowed spent barrels to be replaced with loaded ones.[101][102] According to the Silok, it was convenient enough to be fired in succession by horsemen carrying multiple barrels, and during times of emergency, even women and children could use it easily.[103]
The hwacha is a mobile multiple rocket launcher that uses gunpowder to fire up to 200 singijeon rockets at one time. The hwacha was invented in 1409, but saw its greatest use during the Imjin War, most famously in the Battle of Haengju. Hwachas were used against both land and sea targets.[104]
The Koreans were innovators in the development of naval artillery,[105][106] and produced the most advanced naval cannons in East Asia.[107] In 1380, 100 Goryeo ships armed with gunpowder weapons destroyed 500 Wokou ships at the Battle of Jinpo.[108]
The turtle ship, also known as the geobukseon, was the first armored warship in the world.[109][110][111] Turtle ships were built during the Joseon dynasty beginning in the early 15th century up until the 19th century,[109] but are most often associated with Admiral Yi Sun-sin, who used them in battle against the Japanese in the Imjin War (1592–1598).
The myeonje baegab was a soft bulletproof vest invented in 1867 in the Joseon dynasty.[112][113]
The cheonbochong (천보총; 千步銃), or the "thousand paces gun", was a type of jochong matchlock musket invented in Joseon during the reign of King Sukjong (1674–1720). Compared to other jochongs of the time that had a range of 120m, the cheonbochong was recorded to have a range of 1200m.[114]
The pigyok chinchollae (비격진천뢰; 飛擊震天雷), also called the Flying Thunderbolt,[115] was a time bomb with an adjustable fuse mechanism that was invented by Yi Jangson and first used in the Imjin War at the Battle of Gyeongju in 1592. It was projected into enemy camps and formations using the wangu mortar, and also used at sea.[116][117]
Perhaps the earliest predecessor to the modern machine gun are the chongtong (gun barrel) hwachas of the 15th century. The first of these were created in 1409, in which dozens of stacked rows of bronze gun barrels fired iron bolts.[118] The Moonjong hwacha in 1451 carried 50 gun barrels which each fired sequentially 4 bolts each.[119] The "box" of gun barrels was modular and could be installed and removed on the firing carriage. The gun-barrel type (as opposed to the rocket type) of hwacha predates the weapons considered the earliest forms of machine guns outside of Korea, the Chinese 'Po-Tzu Lien-Chu-P'ao' or 'string-of-100-bullets cannon' developed in the first quarter of the 17th century.[120] The later jujachongtong hwacha developed in 1490 fired 15 iron bullets per barrel, and hundreds of the weapons were produced and deployed throughout the nation.[121][122]

Modern

In 2006, Samsung Techwin released the Samsung SGR-A1, a sentry guard robot designed to replace human counterparts at the Korean Demilitarized Zone. It is the first of its kind to have surveillance, tracking, firing, and voice-recognition systems built into a single unit.[123]
In 2010, DoDaam Systems introduced the Super aEgis II, one of a new breed of automated weapon that can identify, track, and destroy a moving target at a distance of 4 km.[124]
Daewoo's K11 is the first gun of its kind to be operational in the field, making the Republic of Korea Army the first in the world to use an airburst assault rifle as standard issue.[125][126]

Traditional medicine

The traditional Korean sauna, called the hanjeungmak, is a domed structure constructed of stone that was first mentioned in the Sejong Sillok of the Annals of the Joseon Dynasty in the 15th century.[127][128] Supported by Sejong the Great, the hanjeungmak was touted for its health benefits and used to treat illnesses.[127] In the early 15th century, Buddhist monks maintained hanjeungmak clinics, called hanjeungso, to treat sick poor people; these clinics maintained separate facilities for men and women due to high demand.[129] Korean sauna culture and kiln saunas are still popular today, and Korean saunas are ubiquitous.[130]
Koryo hand acupuncture[131] is a modern system of acupuncture, created by Yu Tae-u in the 1970s,[132] in which the hand represents the entire body and is needled or stimulated during treatment.[133] Hand acupuncture is popular among the general population as a form of self-medication in Korea, and has adherents in Japan and North America;[132] it is also popular among overseas Koreans.[134] Korean hand acupuncture is different from American hand reflexology, another form of alternative medicine.[135]
  • Primo vascular system
The primo vascular system, also known as the Bong-Han system, is a new circulatory system discovered by Kim Bong-Han, a professor at the Pyongyang Medical University, in 1961. It is differentiated from the arteriovenous and lympathic systems by its unique anatomical and immunohistochemical signature. Originally named the "Substance of Kyungrak", Professor Kim proposed that the system represents the meridians and collaterals of acupuncture. The primo vascular system was scientifically confirmed in 2002.[136]

Ceramics

 
Inlaid celadon, 12th century
 
Buncheong, 15th century
Korean celadon reached its pinnacle with the invention of the sanggam inlay technique in the early 12th century during the Goryeo period.[137][138][139]
Jinsa "underglaze red", a technique using copper oxide pigment to create copper-red designs, was developed in Korea during the 12th century, and later inspired the "underglaze red" ceramics of the Yuan dynasty.[140][141][142][143]
During the Joseon period, Koreans applied the sanggam tradition to create buncheong ceramics.[144][145] In contrast to the refined elegance of Goryeo celadon, buncheong is designed to be natural, unassuming, and practical.[146] However, the buncheong tradition was gradually replaced by Joseon white porcelain, its aristocratic counterpart, and disappeared in Korea by the end of the 16th century.[145] Buncheong became known and prized in Japan as Mishima.[147][148][149]
The Japanese Karatsu style of ceramics originated in Korea.[150][151]

Music

 
Jeongganbo musical notation system
Jeongganbo is a unique traditional musical notation system created during the time of Sejong the Great that was the first East Asian system to represent rhythm, pitch, and time.[152][153]
First depicted in Goguryeo murals,[154] the janggu is the most representative drum in traditional Korean music.[155]
The most representative traditional instrument of Korea,[90] the gayageum was created in Gaya during the 6th century, and based on the Chinese guzheng.[156]
Originating in the 17th century during the Joseon period, pansori, also known as "Korean folk opera", is a traditional genre of narrative song performed by a sorikkun singer and a gosu drummer.[157] Pansori was inscribed in the Representative List of the Intangible Cultural Heritage of Humanity by UNESCO in 2008.[158]
North Korea has developed many modernized instruments based on traditional instruments. The sohaegeum, junghaegeum, daehaegeum, and jeohaegeum are four-stringed fiddles of varying sizes, based on the traditional haegeum. The eoeungeum is a pear-shaped lute with 5 strings that is similar to the hyangbipa. The cheolhyeongeum and ongnyugeum are modernized zithers, and the jangsaenap is a modernized taepyeongso.[159]
K-pop, or South Korean popular music, began in 1992 with the debut of Seo Taiji and Boys, a band that challenged musical and societal norms in South Korea with music influenced by American genres.[160] Today, K-pop leads the Korean Wave with idol groups such as BTS.

Painting

 
Chaekgeori, 19th century
Chaekgeori (책거리; 冊巨里), translated as "books and things", is a genre of still-life painting from the Joseon period of Korea that features books as the dominant subject.[161] The chaekgeori tradition flourished from the second half of the 18th century to the first half of the 20th century and was enjoyed by all members of the population, from the king to the commoners, revealing the infatuation with books and learning in Korean culture.[162]
  • Munjado
Munjado (문자도; 文字圖), also known as "flower writing" (꽃글씨; kkotgeulssi), is a genre of Korean folk art that enjoyed popularity in the 18th and 19th centuries, in which large Chinese characters associated with Confucian philosophy are painted as a representation of their meaning, with depictions of related stories and themes painted into the characters themselves.[163][164]

Science

Social science

 
Jeong Yak-yong, a proponent of Silhak

In order to provide equality and fairness in taxation for the common people, Sejong the Great issued a royal decree to administer a nationwide public opinion poll regarding a new tax system called Gongbeop in 1430. Over the course of 5 months, the poll surveyed 172,806 people, of which approximately 57% responded with approval for the proposed reform.[169][170]
  • Society for the disabled
The world's first society for the disabled, called the myeongtongsi (명통시; 明通寺), was created by the Joseon government during the early Joseon period. The government-organized myeongtongsi regularly held events for the blind to participate in rituals and ceremonies and receive treatment for illnesses, donations of food and other items, and training for certain jobs.[171][172]
In 1426, Sejong the Great enacted a law that granted government nobi women 100 days of maternity leave after childbirth, which, in 1430, was lengthened by one month before childbirth. In 1434, Sejong also granted the husbands 30 days of paternity leave.[173]
Silhak, also known as "Practical Learning", is a Korean school of thought developed by the seonbi that is dedicated to an empirical approach to statecraft based on pragmatism, instead of a blind and uncritical adherence to Confucianism.[174] Silhak scholars, such as Jeong Yak-yong, emphasized human equality and advocated economic, educational, and social reform.[175]
Juche, translated as "self-reliance" or "self-determination", is the state ideology of North Korea. Implemented in 1956, Juche follows the four principles of "autonomy in ideology, independence in politics, self-sufficiency in economy, and self-reliance in defense".[176]
The blue ocean strategy was developed by W. Chan Kim and Renée Mauborgne, who argue that companies can succeed not by battling competitors, but rather by creating ″blue oceans″ of uncontested market space.
U-City (ubiquitous city) is defined as a "next generation urban space" that includes an integrated set of ubiquitous services: a convergent form of both physical and online spaces. Songdo in South Korea is the first U-City in the world.[177][178]

Physical science

In 1939, vinylon, the second man-made fiber to be invented, after nylon, was developed by Ichiro Sakurada, Ri Sung-gi, and Hiroshi Kawakami at Kyoto University in Japan. However, the fiber was largely ignored until Ri Sung-gi defected to North Korea in 1950 and led its production. Vinylon is the national fiber of North Korea, and is used for the majority of textiles, outstripping fibers such as cotton or nylon.[179][180]

Daundong site 3 4 Heated greenhouseThe first description of a heated greenhouse is from the Sanga Yorok a treatise on husbandry compiled by a royal physician of the Joseon dynasty of Korea during the 1450s in its chapter on cultivating vegetables during winter The treatise contains detailed instructions on constructing a greenhouse that is capable of cultivating vegetables forcing flowers and ripening fruit within an artificially heated environment by utilizing ondol the traditional Korean underfloor heating system to maintain heat and humidity cob walls to insulate heat and semi transparent oiled hanji windows to permit light penetration for plant growth and provide protection from the outside environment The Annals of the Joseon Dynasty confirm that greenhouse like structures incorporating ondol were constructed to provide heat for mandarin orange trees during the winter of 1438 5 Rain gaugeThe first standardized rain gauge called the cheugugi was invented

warming the floors then exits through the chimneys Namhan Mountain Fortress Gyeongcheonsa Pagoda Underfloor heatingOne of the earliest systems of underfloor heating dating back 2 500 years was invented and widely used by Koreans The Korean ondol heating system was thought to be the oldest of its kind until the recent archaeological discovery of a similar heating system in the Alaskan Aleutian Islands However the archaeologist who discovered it agrees with Korean researchers that the two systems developed independently based on the distance of 5 000 kilometers and the absence of ondol in the areas between them 25 26 27 Some Korean researchers have explained this phenomenon by hypothesizing that a whale hunting people from the Korean Peninsula migrated by sea to Alaska during prehistoric times 28 29 30 Inspired by the Korean ondol hydronic radiant floor heating system the American architect Frank Lloyd Wright developed and introduced the first radiant heating system using hot water pipes 31 32 RefrigerationThe ancient Silla kingdom created an early refrigeration system called seokbinggo which were subterranean chambers used to store ice and food 33 34 Korean
