Korea: Hong Daeyong (1731 - 1783), philosopher, astronomer and mathematician during the late Joseon Kingdom (1392 - 1897). Also known as Damheon, Hong was an early promoter of Korean industrialization and the development of trade by using Western technologies.
Johannes Gensfleisch zur Laden zum Gutenberg was a blacksmith, goldsmith, printer, and publisher who introduced the printing press. His usage of movable type printing started the Printing Revolution and is widely regarded as the most important event of the modern period. It played a key role in the development of the Renaissance, Reformation and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.<br/><br/>

Gutenberg was the first European to use movable type printing, in around 1439. Among his many contributions to printing are: the invention of a process for mass-producing movable type; the use of oil-based ink; and the use of a wooden printing press similar to the agricultural screw presses of the period. His acclaim is due to the engineering of these elements into a practical system for the mass production of printed books, that was economically viable for printers and readers alike. Gutenberg's method for making type was an improvement over the Chinese Bi Sheng's from 400 years earlier, and is traditionally considered to have included a type metal alloy and a hand mould for casting type.<br/><br/>

The use of durable metallic movable type allowed rapid mass production of printed works. Gutenberg's printing technology spread rapidly throughout Europe, and quickly replaced most of the handwritten manuscript methods of book production throughout the world. Woodblock printing, rubrication, and engraving continued to be used to supplement Gutenberg's printing process.<br/><br/>

His first major work using his printing methods was the Gutenberg Bible.
Between 1405 and 1433, the Ming government sponsored a series of seven naval expeditions. The Yongle emperor designed them to establish a Chinese presence, impose imperial control over trade, impress foreign peoples in the Indian Ocean basin and extend the empire's tributary system.<br/><br/>

Zheng He was placed as the admiral in control of the huge fleet and armed forces that undertook these expeditions. Zheng He's first voyage consisted of a fleet of up to 317 ships holding almost 28,000 crewmen, with each ship housing up to 500 men.<br/><br/>

Zheng He's fleets visited Arabia, Brunei, East Africa, India, the Malay Archipelago and Thailand, dispensing and receiving goods along the way. Zheng He presented gifts of gold, silver, porcelain and silk; in return, China received such novelties as ostriches, zebras, camels, ivory and giraffes.

Around 2000 years ago, Chinese in Sichuan province originated deep drilling. The primary motive for deep drilling in China was the search for salt. Even as recently as 1965, 16.5% of China’s salt supplies came from brine pumped out of deep boreholes, making this source of supply second only to sea salt.<br/><br/>

The ancient percussive cable drilling system was called 'churn'. The derrick had a height of 11m and all parts of the rig were made from wood (mainly bamboo). A large wooden drum, 5m in diameter, was used to raise and lower the drill. A rocking movement of the balancing beam created the percussive impulses on the bit, which sometimes weighed as much as 140kg. By alternately lifting this tool and letting it fall, the Chinese could achieved a well depth of 600m.<br/><br/>

The deep drilling for brine yielded natural gas (primarily methane) from time to time. The boreholes producing methane were known to the Chinese as 'fire wells', thus drilling for natural gas followed and was developed at the same time.<br/><br/>

Bamboo tubes were used as pipelines, carrying both brine and natural gas for many miles, sometimes passing under roads and sometimes going overhead on trestles. Among other uses, natural gas was used to heat evaporation pans of brine to make salt.
Sichuan Province has over 130 different mineral resources. Sichuan contains some 90% of all titanium, 70% of all vanadium and 80% of all cobalt in China. It also has large deposits of iron, copper, aluminum, platinum, nickel, lead, zinc, coal, petroleum, antimony, phosphorus, asbestos, and marble.
The Wujing Zongyao or 'Collection of the Most Important Military Techniques' is a Chinese military compendium written in 1044 CE, during the Northern Song Dynasty.<br/><br/>

Its authors were the prominent scholars Zeng Gongliang, Ding Du  and Yang Weide, whose writing influenced many later Chinese military writers. The book covered a wide range of subjects, everything from naval warships to different types of catapults.<br/><br/>

Although the English philosopher and friar Roger Bacon was the first Westerner to mention the sole ingredients of gunpowder in 1267 (i.e. strictly saltpetre, sulphur, and charcoal) when referring to firecrackers in 'various parts of the world', the Wujing Zongyao was the first book in history to record the written formulas for gunpowder solutions containing saltpetre, sulphur, and charcoal, along with many added ingredients.<br/><br/>

It also described an early form of the compass (using thermoremanence), and had the oldest illustration of a Chinese Greek Fire flamethrower with a double-acting two-piston cylinder-pump that shot a continuous blast of flame.
Wang Zhen (Wade–Giles: Wang Chen, fl. 1290 – 1333) was an official of the Yuan Dynasty (1271 – 1368 CE). He was one of the early innovators of the wooden movable type printing system.<br/><br/>

His illustrated agricultural treatise was also one of the most advanced of its day, covering a wide range of equipment and technologies available in the late 13th and early 14th century.

Johannes Gensfleisch zur Laden zum Gutenberg was a blacksmith, goldsmith, printer, and publisher who introduced the printing press. His usage of movable type printing started the Printing Revolution and is widely regarded as the most important event of the modern period. It played a key role in the development of the Renaissance, Reformation and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.<br/><br/>

The Tacuinum (sometimes Taccuinum) Sanitatis is a medieval handbook on health and wellbeing, based on the Taqwim al‑sihha تقويم الصحة ('Maintenance of Health'), an eleventh-century Arab medical treatise by Ibn Butlan of Baghdad.<br/><br/>

Ibn Butlân was a Christian physician born in Baghdad and who died in 1068. He sets forth the six elements necessary to maintain daily health: food and drink, air and the environment, activity and rest, sleep and wakefulness, secretions and excretions of humours, changes or states of mind (happiness, anger, shame, etc). According to Ibn Butlân, illnesses are the result of changes in the balance of some of these elements, therefore he recommended a life in harmony with nature in order to maintain or recover one’s health.<br/><br/>

Ibn Butlân also teaches us to enjoy each season of the year, the consequences of each type of climate, wind and snow. He points out the importance of spiritual wellbeing and mentions, for example, the benefits of listening to music, dancing or having a pleasant conversation.<br/><br/>

Aimed at a cultured lay audience, the text exists in several variant Latin versions, the manuscripts of which are characteristically profusely illustrated. The short paragraphs of the treatise were freely translated into Latin in mid-thirteenth-century Palermo or Naples, continuing an Italo-Norman tradition as one of the prime sites for peaceable inter-cultural contact between the Islamic and European worlds.<br/><br/>

Four handsomely illustrated complete late fourteenth-century manuscripts of the Taccuinum, all produced in Lombardy, survive, in Vienna, Paris, Liège and Rome, as well as scattered illustrations from others, as well as fifteenth-century codices.

A junk is an ancient Chinese sailing vessel design still in use today. Junks were developed during the Han Dynasty (206 BC–220 AD) and were used as sea-going vessels as early as the 2nd century AD. They evolved in the later dynasties, and were used throughout Asia for extensive ocean voyages. They were found, and in lesser numbers are still found, throughout South-East Asia and India, but primarily in China, perhaps most famously in Hong Kong.

For millennia, archery has played a pivotal role in Chinese history. In particular, archery featured prominently in ancient Chinese culture and philosophy: archery was one of the Six Noble Arts of the Zhou dynasty (1146–256 BCE).<br/><br/>

Archery skill was a virtue for Chinese emperors; Confucius himself was an archery teacher; and Lie Zi (a Daoist philosopher) was an avid archer. Because the cultures associated with Chinese society spanned a wide geography and time range, the techniques and equipment associated with Chinese archery are diverse.
Between 1405 and 1433, the Ming government sponsored a series of seven naval expeditions. The Yongle emperor designed them to establish a Chinese presence, impose imperial control over trade, impress foreign peoples in the Indian Ocean basin and extend the empire's tributary system.<br/><br/>

Zheng He was placed as the admiral in control of the huge fleet and armed forces that undertook these expeditions. Zheng He's first voyage consisted of a fleet of up to 317 ships holding almost 28,000 crewmen, with each ship housing up to 500 men.<br/><br/>

The Wujing Zongyao (simplified Chinese: 武经总要; traditional Chinese: 武經總要; pinyin: Wǔjīng Zǒngyào; Wade–Giles: Wu Ching Tsung Yao; literally: 'Collection of the Most Important Military Techniques') is a Chinese military compendium written in 1044 CE, during the Northern Song Dynasty.<br/><br/>

Its authors were the prominent scholars Zeng Gongliang (曾公亮), Ding Du (丁度) and Yang Weide (楊惟德), whose writing influenced many later Chinese military writers. The book covered a wide range of subjects, everything from naval warships to different types of catapults.<br/><br/>

Although the English philosopher and friar Roger Bacon was the first Westerner to mention the sole ingredients of gunpowder in 1267 (i.e. strictly saltpetre, sulphur, and charcoal) when referring to firecrackers in 'various parts of the world', the Wujing Zongyao was the first book in history to record the written formulas for gunpowder solutions containing saltpetre, sulphur, and charcoal, along with many added ingredients.<br/><br/>

It also described an early form of the compass (using thermoremanence), and had the oldest illustration of a Chinese Greek Fire flamethrower with a double-acting two-piston cylinder-pump that shot a continuous blast of flame.

The People's Liberation Army Navy (PLAN or PLA Navy, Chinese: Rénmín Jiěfàngjūn Hǎijūn) is the naval branch of the People's Liberation Army (PLA), the military of the People's Republic of China. Until the early 1990s, the navy performed a subordinate role to the PLA Land Forces. Since then, it has undergone rapid modernisation.<br/><br/>

It is the second largest naval service in the world. With a personnel strength of over 250,000, the PLAN also includes the 35,000 strong Coastal Defense Force and the 56,000 man Naval infantry/Marines, plus a 56,000 PLAN Aviation naval air arm operating several hundred land-based aircraft and ship-based helicopters. As part of its overall program of naval modernization, the PLAN is actively developing a blue-water navy.

Shen Du's poem:<br/><br/><i>In the corner of the western seas, in the stagnant waters of a great morass,
Truly was produced a qilin, whose shape was as high as fifteen feet.
With the body of a deer and the tail of an ox, and a fleshy, boneless horn,
With luminous spots like a red cloud or purple mist.
Its hoofs do not tread on living beings and in its wanderings it carefully selects its ground.</i><br/><br/><i>It walks in stately fashion and in its every motion it observes a rhythm,
Its harmonious voice sounds like a bell or a musical tube.
Gentle is this animal, that has in antiquity been seen but once,
The manifestation of its divine spirit rises up to heaven’s abode.</i>
A 14th century illustration of a Chinese cannon, or eruptor, which fired proto-shells as cast iron bombs. This illustration was featured in the 14th century military treatise of the Huolongjing, edited and compiled by Liu Ji and Jiao Yu, with the preface added in 1412. This specific cannon was called the "flying-cloud thunderclap eruptor" (feiyun pilipao).
Johannes Gensfleisch zur Laden zum Gutenberg was a blacksmith, goldsmith, printer, and publisher who introduced the printing press. His usage of movable type printing started the Printing Revolution and is widely regarded as the most important event of the modern period. It played a key role in the development of the Renaissance, Reformation and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.<br/><br/>

Gutenberg was the first European to use movable type printing, in around 1439. Among his many contributions to printing are: the invention of a process for mass-producing movable type; the use of oil-based ink; and the use of a wooden printing press similar to the agricultural screw presses of the period. His acclaim is due to the engineering of these elements into a practical system for the mass production of printed books, that was economically viable for printers and readers alike. Gutenberg's method for making type is an improvement over the Chinese Bi Sheng's from 400 years earlier, and is traditionally considered to have included a type metal alloy and a hand mould for casting type.<br/><br/>

The use of durable metallic movable type allowed rapid mass production of printed works. Gutenberg's printing technology spread rapidly throughout Europe, and quickly replaced most of the handwritten manuscript methods of book production throughout the world. Woodblock printing, rubrication, and engraving continued to be used to supplement Gutenberg's printing process.<br/><br/>

His first major work using his printing methods was the Gutenberg Bible.
