One of the best known artifacts of Korea's history of science and technology is Cheomseongdae, a 9-meter high observatory built in 633. It is considered to be the world's oldest surviving astronomical observatory. The world's earliest known printed document is a Buddhist scripture printed in Korea in 750-751 CE. The world's first metal movable type was invented in Korea in 1232, before Johann Gutenberg developed metal letterset type. Though Koreans used wooden printing blocks prior 751, metal movable type was a significant development in printing allowing continued use of the same type. Some Chinese thought Korean porcelains were of the finest quality before and during the Goryeo Dynasty. During the Goryeo period, Korea advanced traditional arts and crafts, such as white celadon glazes, fine silk, paper and Sword making. Hangul, perhaps the most scientifically designed script in widespread use, was created by King Sejong the Great in 1443. An automated water clock was invented in 1434 by Jang Yeong-sil, who later developed a more complicated water-clock with additional astronomical devices, water gauge, and the rain gauge. During the Joseon period, Korean silk was highly regarded by China and Korean pottery made with blue-green celadon were of the highest quality in the world. Also, during this time, the world's first ironclad warships, the Geobukseon (Turtle Ship) were invented, as well as other weapons such as the Bikeokjinchonlae and the Hwacha. |
