List of Korean inventions and discoveries explained

This is a list of Korean inventions and discoveries; Koreans have made contributions to science and technology from ancient to modern times. In the contemporary era, 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] The Koreans have made contributions across a number of scientific and technological domains. In particular, the country has played a role in the modern Digital Revolution through its large electronics industry with a number of modern revolutionary and widespread technologies in fields such as electronics and robotics introduced by Korean engineers, entrepreneurs, inventors, and scientists.

Agriculture

The first standardized rain gauge, called the cheugugi, was invented during the reign of Sejong the Great in the Joseon dynasty of Korea.[3] [4] [5] [6] [7] 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.

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.[8]

The homi, which dates back to the Bronze Age, is one of the most representative agricultural tools of Korea.[9] Its signature tapered blade was developed during the Later Silla period.[10] In recent times, the homi (known by names such as the "Ho-Mi EZ Digger" and "Korean hand plow")[11] [12] [13] has gained popularity in the West.[14]

Architecture

See main article: Korean architecture.

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.[214] [215] [216] 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.[217] [218] [219] 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.[220] [221]

The ancient Silla kingdom created an early refrigeration system called seokbinggo, which were subterranean chambers used to store ice and food.[222] [223]

Koreans developed a unique and distinct fortress tradition.[224] 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.[225] [226] Korean fortresses were invented by Goguryeo and spread to Baekje and Silla,[227] and then inherited and further developed by Goryeo and then Joseon. Goguryeo fortress ruins have been found in about 170 sites to date, including in China;[228] one of the most notable among them is Ansi Fortress, which successfully defended against Tang Taizong during the Goguryeo–Tang War.[229] [230] Korea, beginning with Goguryeo,[231] [232] has been called "a country of fortresses";[233] [234] almost 2,400 mountain fortress sites have been found in Korea. Korean-style fortresses can also be found in Japan, which were constructed and supervised by immigrants of Baekje origin.

Koreans created a unique and distinct pagoda tradition using stone.[235] [236] [237] 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.[238] [239] [240] [241] [242] 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. The stone pagoda tradition was propagated by the great abundance of high quality granite in Korea,[243] which also led to other granite creations such as the Seokguram and Cheomseongdae. Goryeo, a devoutly Buddhist state, also inherited the stone pagoda tradition.[244]

Astronomy

The earliest known constellation patterns in Korea can be found on dolmens dating back to 3000 BC.[245] 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.[246]

The Cheomseongdae is the oldest surviving astronomical observatory in Asia,[247] [248] [249] and possibly the world.[250] [251] [252] 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.[253]

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.[254] The Korean alphabet is unique among the world's writing systems, in that it combines aspects of featural, phonemic, and syllabic representation.[255] Hangul, originally named Hunminjeongeum, was personally created by Sejong the Great[256] [257] to promote literacy among the common people.[258]

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.[259] [260] [261] [262] Some of them may have influenced the development of kana in Japan.[263] [264]

Printing

Movable metal type was invented in Korea in the early thirteenth century,[265] [266] [267] [268] [269] predating Gutenberg's invention in Europe by two centuries[270] 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.[271] The earliest surviving book to be printed with movable metal type is the Jikji, dated to 1377.[272] The first lead type in the world is the Byeongjinja created in 1436.[273] 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.[274]

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.[275] [276]

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.[277] 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.[278] 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.[279] Thus, the Striking Palace Clepsydra is the first hydro-mechanically engineered dual-time clock in the history of horology.[280] [281]

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.[282]

Military

Traditional

Iron plate armor was used by Silla and Gaya beginning in the early 4th century.[283] 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."[284]

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.[285] [286] 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.[287]

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.[288]

The Koreans were innovators in the development of naval artillery,[289] [290] and produced the most advanced naval cannons in East Asia.[291] In 1380, 100 Goryeo ships armed with gunpowder weapons destroyed 500 Wokou ships at the Battle of Jinpo.[292]

The turtle ship, also known as the geobukseon, was the first armored warship in the world.[293] [294] [295] Turtle ships were built during the Joseon dynasty beginning in the early 15th century up until the 19th century, 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.[296] [297]

The cheonbochong, 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.[298]

The pigyok chinchollae, also called the Flying Thunderbolt,[299] 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.[300] [301]

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.[302] The Moonjong hwacha in 1451 carried 50 gun barrels which each fired sequentially 4 bolts each.[303] 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.[304] 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.[305] [306]

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.[307]

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.[308]

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.[309] [310]

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.[311] [312] Supported by Sejong the Great, the hanjeungmak was touted for its health benefits and used to treat illnesses. 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.[313] Korean sauna culture and kiln saunas are still popular today, and Korean saunas are ubiquitous.[314]

Koryo hand acupuncture[315] is a modern system of acupuncture, created by Yu Tae-u in the 1970s,[316] in which the hand represents the entire body and is needled or stimulated during treatment.[317] Hand acupuncture is popular among the general population as a form of self-medication in Korea, and has adherents in Japan and North America; it is also popular among overseas Koreans.[318] Korean hand acupuncture is different from American hand reflexology, another form of alternative medicine.[319]

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.[320]

Ceramics

See main article: Korean pottery and porcelain.

During the Joseon period, Koreans applied the sanggam tradition to create buncheong ceramics.[321] [322] In contrast to the refined elegance of Goryeo celadon, buncheong is designed to be natural, unassuming, and practical.[323] 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. Buncheong became known and prized in Japan as Mishima.[324] [325] [326]

Korean celadon reached its pinnacle with the invention of the sanggam inlay technique in the early 12th century during the Goryeo period.[327] [328] [329]

The Japanese Karatsu style of ceramics originated in Korea.[330] [331]

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.[332] [333] [334] [335]

The earliest evidence of ssireum, or "Korean wrestling", dates back to the Goguryeo period. Originally used in military applications, ssireum became a popular pastime of the people, including many Korean kings, during the Goryeo and Joseon periods. In the 20th century, ssireum became a nationally televised sport in South Korea.[360]

Products

The Korean exfoliating mitt[366] is a mass-produced bath product used to scrub and peel the outermost layer of skin; it was invented in Busan by Kim Won-jo(CEO of Hanil Textile) in 1967. Since then, the Italy towel has become a household item in Korean homes and a staple item in Korean saunas. The Korean exfoliating mitt was named the Italy towel because the viscose fabric used to make it was imported from Italy at the time.[367] [368]

Gable tops were invented by Dr. Shin Seok-kyun in 1953 allowing for milk cartons to be sealed tight after opening for later use. Dr. Shin Seok-kyun, so-called Edison of Korea, unfortunately he couldn’t file his patent given the turbulent context in the middle of Korean War. Eventually, this gable top carton made its way into the U.S. by U.S. army and was set as the international standard.These days, gable top cartons are used all around the world.[369]

The dol bed, or stone bed, is a manufactured bed that has the same heating effect as ondol and is purported to have health benefits.[370] The dol bed industry is estimated to be worth 100 billion South Korean won, comprising 30 to 40 percent of the entire bed industry in South Korea; dol beds are most popular with middle-aged people in their 40s and 50s.[371] [372]
