The second series of Science in Korea stamps is released by Korea Post. Joseon's Jang Yeong-sil and Heo Jun and modern times' Lee Tae-kyu are featured on the postage stamps.

Korea Post has selected Jang Yeong-sil (장영실, 蔣英實), Heo Jun (허준, 許浚) and Lee Tae-kyu (이태규, 李泰圭) to be inducted into the Korea Scientists and Engineers Hall of Fame and to be represented on its second series of Science in Korea stamps.

Jang Yeong-sil (1390-1450) is one of the world's best technicians who led science and technology during the Joseon Dynasty. He was born as a slave but overcame that limitation through talent and effort, and created a number of inventions as a technician. He invented a clepsydra, the Borugak Jagyeongnu (자격루, 自擊漏), an elaborate water clock with an automatic time alert, a hemispherical sundial (앙부일구, 仰釜日晷) and a celestial globe (혼천의, 渾天儀), a model of the celestial sphere that can help determine the position of the stars. He was also involved in creating metal type.

Heo Jun (1539-1615) is one of the scientists who greatly improved traditional medicine. The "Dongui Bogam" (동의보감, 東醫寶鑑) is a medical encyclopedia that synthesizes both Chinese and Korean medicine. The book is organized by symptom of the disease, diagnosis, prognosis and prevention, and it's considered to be a paragon of traditional medicine.

Finally, Lee Tae-Kyu (1902-1992) was a theoretical chemist who worked in Japan and the United States. He received his doctorate in science from Kyoto Imperial University and was appointed as the first professor there. After Korean independence, he was recognized in the U.S. for his doctorate thesis about the Ree-Eyring theory. Furthermore, he contributed to the development of chemistry by fostering a younger generation of chemists at the University of Utah and at the Korea Advanced Institute for Science and Technology (KAIST).
