新竹市清華大學新日晷 New Sundial on NTHU campus, Taiwan

這日晷在新竹市清華大學校園內，2006年為慶祝清大在台復校50週年而建。 其獨特之處有三： 1. 面盤，就是那藍白色像水又像天空的大圓面，向北傾斜5.2度。 2. 投影體的南、北兩端都開有小孔，夜裡從南孔向北孔望去，可見北極星。 3. 面盤上的日期線，除了夏至、春分、秋分和冬至外還有清大校慶日和雙十國慶日。
在面盤東北方地面上有兩塊銅牌，一塊說明建造原委，另一塊是時差修正表。
This sundial was given to the Nat'l Tsing Hua University in April, 2006 as a gift to celebrate its 50th anniversary of re-erecting at Hsinchu. The mosaic dial face, 8m in diameter, is tilted 5.2 degrees down north. The highest point of the gnomon is about 185 cm from the face, which is decorated in blue and white to imply water and sky. The gnomon's east-west width is 30 cm. Near the top edge of north end is there a hole. A smaller hole is found at south end. Through these two holes, one may see the North star in the night. Five calendar lines are given; summer and winter solstices, equinoxes, the National Day (Oct. 10th) and the University anniversary (Apr. 29).
There are two bronze plates on the ground north-east to the dial face. One states why and how this sundial was built, the other gives an 'equation of time' table on a basis of every minute of change. The picture above shows only the latter.
This sundial was designed by Professor Emeritus Chi-Lian Chiu (chemist) and Mr. PoJui Lin (artist).
