Koreans have made many important contributions to science and technology, from long ago until now. This list shows some of the inventions and discoveries made by people from Korea. In recent years, South Korea has become a leader in new technologies, especially in the Digital Revolution. The country has a very big electronics industry and is known for creating many modern and important technologies. Korean engineers, business leaders, inventors, and scientists have helped change fields like electronics and robotics with their clever ideas and hard work. Because of this, South Korea plays an important role in shaping the future of technology around the world.
Agriculture
The Koreans made many useful tools and ways for farming. They made the first rain gauge, called the cheugugi, in the time of Sejong the Great. This helped people know how much rain fell.
Koreans were also the first to describe a heated greenhouse. They used a heating system called ondol and special walls and windows to grow plants in cold weather. They helped orange trees live through winter in these greenhouses.
Another important farming tool was the homi, a hand plow used since old times. It is still used in many places today.
Koreans were among the first to grow soybeans, which are now an important food around the world.
Aquaculture
Koreans have a long history of fishing and farming the sea. Ancient limestone net sinkers from 27,000 BC show some of the earliest fishing nets ever found.
In 2016, scientists in South Korea were the first to farm Alaska pollock, a fish important to the country. They helped these fish lay eggs faster than in the wild. Korea also has a long tradition of growing seaweed, starting in the 1600s. There is also evidence that people in Korea were catching whales thousands of years ago.
Mathematics
Koreans have made interesting discoveries in math. Chisanbop is a way to do calculations using fingers, invented in Korea in the 1940s. The hexagonal tortoise problem was created by Choi Seok-jeong during the Joseon period. Choi Seok-jeong also wrote about the Latin square much earlier than Leonhard Euler. Another Korean mathematician, Rimhak Ree, discovered the Ree group in the study of group theory.
Technology
Electronics
South Korea has made many important advances in electronics. In 2015, the world’s first 360-degree color hologram was created by the Electronics and Telecommunications Research Institute. In 2014, a special pen that can print in 3D on a very small scale was made by a scientist at Korea University. Samsung introduced the first smartphone that could use 5G technology in 2019, and in 2013 they made the first phone with a curved screen.
Samsung was also the first to show a special type of computer memory in 1997, and in 2012 they made a mouse that could track eye movements without special glasses. In 2012, scientists showed a very thin and bendable battery, and in 1967, two inventors created a key part of modern computers. Samsung started making a fast type of computer memory in 1998, and in 2010 they made the first phone that could use LTE for faster internet.
The important invention happened in 1959, and it is the main part in most electronic devices today. Samsung made the first phone that could play MP3 music in 1999, and the first MP3 player came out in 1997. In 2014, scientists made buses that could get power from the road itself using special wireless technology. LG made a screen technology that Apple later used.

A Korean company also opened a real place where people could trade special online money, and in 2005 they made one of the first places where people could watch live videos online.
Science
Social science
Koreans have made many important discoveries in social science. One example is the double-entry bookkeeping system, which was created in the Goryeo kingdom by merchants in Kaesong, earlier than in Italy. Another key development was public opinion polling. In 1430, Sejong the Great used a nationwide poll to ask people about a new tax system.
There have also been advances in supporting people with disabilities. The first society for the blind was created during the Joseon period, offering events, treatment, and training. Parental leave laws were introduced, giving women 100 days of leave after childbirth and men 30 days after their partner's birth, starting in 1426.
Physical science
In physical science, Koreans have contributed to many areas. Mannque Rho and Gerald E. Brown developed Brown-Rho scaling, which helps predict how particles change in dense environments. Moo-Young Han and Yoichiro Nambu introduced the idea of color charge, a key part of how particles interact. Jisoon Ihm started the field of computational materials physics, using computers to study materials.
Other important work includes FINEX technology for making iron, developed by POSCO and Siemens VAI. POSCO also created a very strong type of steel called Giga steel. Researchers have made advances in graphene, a special material with many uses, and developed new microscopes for viewing cells in three dimensions. There have been many other discoveries in areas like physics and materials science.
Life science
In life science, Koreans have made many valuable contributions. One key discovery is the Triangle of U, which explains the relationships between certain plants. The first vaccine for a certain virus was developed in Korea, helping protect people from serious illness.
Korea was also the first to clone a dog, achieving a major breakthrough in animal cloning. Scientists have developed new medicines to treat infections, diabetes, high blood pressure, and other health problems. There have also been advances in surgery techniques, making operations safer and more effective for patients.
Architecture
Main article: Korean architecture
Koreans invented an early heating system under floors called ondol over 2,500 years ago. This heating system was used in Korea and inspired other designs.
In ancient times, the Silla kingdom made a special underground room called seokbinggo to keep food cold.
Koreans built strong stone forts on hills and mountains. These forts were different from those in nearby lands and helped protect homes.
Koreans made special stone towers called pagodas for religious reasons. These stone towers became a famous part of Korean culture.
Astronomy
The earliest known constellation patterns in Korea are on dolmens from 3000 BC. The Cheonsang Yeolcha Bunyajido is a star chart made of black marble. It was finished in 1395 during the time of King Taejo. It is thought to be the world's second oldest star chart carved in stone.
The Cheomseongdae is the oldest surviving astronomy building in Asia, possibly the world. It was built in Seorabeol, the capital of Silla, in the 7th century during the time of Queen Seondeok. It inspired the building of observatories in Baekje and Japan.
Writing
Hangul is the world's first writing system where the shapes of the letters show features of the sounds they make. It was created by Sejong the Great to help everyone learn to read and write easily.
Before Hangul, Koreans used several writing systems along with Hanja, such as idu, hyangchal, gugyeol, and gakpil. These early systems might have also influenced the development of kana in Japan.
Printing
People in Goryeo (which is now Korea) invented the movable metal printing press in the early thirteenth century. The first book printed with this press was called the Prescribed Ritual Texts of the Past and Present in 1234. The oldest surviving book printed this way is called the Jikji, from 1377. The first lead type ever made was called the Byeongjinja, created in 1436.
The Jobo, mentioned in the Annals of the Joseon Dynasty, might be the world's oldest newspaper. It started in 1577 and was printed every day. It shared news about the weather, stars, and what was happening at the time.
Horology
A Korean startup company made the world’s first Braille smartwatch, called the Dot. This watch helps people who are blind or have low vision read information by touch. It connects to other devices using Bluetooth.
Military
Koreans have made many important military inventions. In the past, they created strong iron plate armor and early handheld firearms called "se-chongtong." They also invented the hwacha, a machine that could shoot many rockets at once, and the world’s first armored warship, the turtle ship.
Today, South Korea leads in smart weapons. Companies have made robots to guard borders, advanced weapons that can hit faraway targets, and special rifles that can shoot in different directions. These inventions show Korea’s long history as a leader in defense technology.
Alternative medicine
Korean culture has a special type of sauna called the hanjeungmak. This dome-shaped stone building was first written about in the 15th century and was supported by King Sejong the Great. People believed it helped with health and treating sickness. Even today, Korean saunas are very popular.
Another unique idea is Koryo hand acupuncture, created in the 1970s. In this method, the hand is thought to represent the whole body, and special treatments are done on the hand instead of other parts. Many people in Korea and other places use this method for self-care.
There is also a theory about a special body system called the primo vascular system. A professor in 1961 described this system, which is different from normal blood vessels. He thought it was connected to old ideas about energy paths in the body. Some studies in 2002 said they found proof of this system.

Ceramics
Main article: Korean pottery and porcelain
During the Joseon period, Koreans made buncheong ceramics. Unlike the fancy Goryeo celadon, buncheong looked simple and useful. Later, Joseon white porcelain became more popular with rich people, and buncheong disappeared in Korea by the late 1500s. It later became valued in Japan as Mishima.
Korean celadon became special when they invented the sanggam inlay method in the early 1100s during the Goryeo period.
The Japanese style called Karatsu in ceramics began in Korea.
A method called Jinsa "underglaze red" was made in Korea in the 1100s. It used a special pigment to create red designs, and this idea later inspired similar ceramics in the Yuan dynasty.

Koreans have created many exciting martial arts. One example is Taekkyeon. It may have started from an old fighting style. Taekkyeon became popular again and was recognized by UNESCO in 2011.
Another famous martial art is Ssireum, often called Korean wrestling. It existed in ancient times and was used by soldiers. Over time, it became a sport enjoyed by all, and today many watch it on television in South Korea.
There is also Gukgung, a traditional form of Korean archery. Practitioners use a special bow called the gakgung, made from horn, to aim and shoot with skill.
Sports
Korea has created some interesting sports. Jokgu was invented in 1960 by members of the Republic of Korea Air Force. It mixes ideas from football and volleyball, inspired by a Southeast Asian game called sepak takraw.
Another old game is Jangchigi, which looks a bit like hockey. It started a long time ago during the Three Kingdoms period. There was also a game called masanggyeokgu, similar to polo, from the same time. Taekwondo, made in 1955, is now South Korea's national sport and an Olympic sport since the year 2000. It comes from old Korean fighting styles and a type of karate called Shotokan.
Products
The Italy towel is a special bath product made in Busan by Kim Won-jo in 1967. It helps scrub and peel the top layer of skin and is common in Korean homes and Korean saunas. It’s called the Italy towel because the fabric comes from Italy.
Gable tops for milk cartons were invented by Dr. Shin Seok-kyun in 1953. These tops let you seal the carton after opening it. Though Dr. Shin couldn’t patent his idea during the Korean War, the design later became the worldwide standard.
Other popular Korean products include the electrically heated stone bed, which warms like traditional heating systems, the circle contact lens that changes the look of the eye, and sheet masks, which are soaked in special skincare liquids. There is also Lock & Lock, a container system for food storage.
Miscellaneous
Thundersticks, called makdae pungseon in Korea, are inflatable plastic noisemakers. People use them at sports games, political events, and concerts. They were created by BalloonStix Korea and first used in 1994 at an LG Twins baseball game.
The jige, or A-frame carrier, is a traditional Korean wooden tool. It helped people carry heavy loads, especially in Korea's hilly areas. It was also used by troops during the Korean War.
