And his deep consideration of the poor. The technological achievements shall not be mine but all people of the world. He invented Gapinja, movable metal type inpromoting the development of printing thanks to the more aesthetic and precise technology and allowing numerous documents to be printed. Born as a slave of the government offices, he disappeared into history without leaving any record of his death.

With the demise of the great leader, King Sejong the Great, the brilliant scientific culture of 15th century Joseon could not develop further. Far later, the Northern School began to accept western astronomy through Beijing and since then the Kyoto Time, which was adopted during the Japanese colonial period, has been used as the standard time for Korea until today.

If King Sejong and Jang Young Sil had been successful in blooming the scientific dream, could it have been possible for us to be using the Korean standard time? VANK, cyber diplomat of Korea, is looking for young people, who dream of a new Korea that will lead world-wide change. Korea played a central role at establishing creative cultures across Asia, actively leading and exploring Asia region and northeast Asia in particular.

Although the king was against the decree, Jang was jailed for a long time and was expelled from the royal palace. Later events of his life, including the date of his death, were not recorded. There are many statues of Jan Yeong-Sil around Korea. The one I stumbled upon is located on the top floor of the National Science Museum. Water clock [ edit ].

Jang met Sejong's expectations in crafts and engineering and was allowed to work as a government official in the palace. Sejong's first assignment to Jang was to build a celestial globe to measure astronomical objects. Books obtained from Arabian and Chinese scholars were not complete in their instructions, because these devices could also be used for military purposes.

After two months of study, he made a spherical device that could perform with mediocre accuracy. The Honcheonui depended on a waterwheel to rotate the internal globe to indicate time. In general, metal movable type printing blocks surpassed the wooden counterparts in durability, clarity, and longevity. The Gabinja set was made of copper-zinc and lead-tin alloys.

The Gabinja type face set was said to be able to print twice as many copies as the previous Gyeongjaja type face set and could print Chinese characters in astounding beauty and clarity. The Joseon court reproduced the Gabinja set six times during the next years. Self-striking water clocks had already been invented by the Arabians and the Chinese in[22] and a more primitive form was in use by the Koreans.

Although there is no archaeological evidence, Samguk Sagi records that an office overlooking the use of water clocks had been established during the Three Kingdoms Period. The Korean version consisted of two stacked jars of water, with water dropping from the top to the bottom at a measured rate. The level of the water indicated the time of the day.

This was very inconvenient because a person had to be always be on guard, so that at each hour he or she could bang a drum to inform the public. Upon hearing about the usage of self-striking water clocks in foreign countries, Sejong assigned Jang and other scientists to build a clock emulating such automatic devices. They failed in developing an operational water clock.

Therefore, Jang went to China to study the various designs of water clocks. Circling the clock were 12 wooden figures that served as indicator of time.
