As part of the celebration marking NTHU’s 50th year in Taiwan, the Tze Chiang Foundationof Science and Technology（自強基金會）commissioned Chiu Chi Lian（邱紀良）, a retired professor from the Department of Chemistry, and Lin Po Jui（林伯瑞）, Artist in Residence, to design and install a new sundial which embodies the school motto “Self-discipline and social commitment” （自強不息厚德載物） .Located on the Plaza in front of the Chemical Engineering Building, Sundial（2005）has a slanted face covered with blue and white fragmented tiles reminiscent of the sky, and provides accurate time. The style is oriented on a north-south axis and resembles a finger; through a small hole inside the style can be seen the North Star. The larger hole in the style has openings facing east and west, representing the interaction between the civilizations of the East and West. This sundial’s shadow also indicates the date on the small circles on its beveled edge. The shadow shifts south in the summer and north in the winter; on the winter solstice the shadow reaches the northernmost point on the dial, and vice versa.
