The vertical plus vertical azimuth sundial for HuLin middle high school students

中文讀者請至 http://blog.xuite.net/nycl.chiu/blog/23501165

The HuLin middle high school in HsinChu city, Taiwan invited me to give a speech on sundial on the 9th of April. I prepared a compound dial, vertical plus vertical azimuth, model and hand out on which the layout and the instruction were given so that each student could make the same one for themselves after.

The design of the sundial faces is displayed in the following photos. One gnomon plate serves for two dials: the horizontal edge for the vertical azimuth dial and the slope edge for the normal vertical dial. It reads the standard time.

關於我自己

我喜歡金剛經和維摩詰經。希望大家願意對我多指導。從清大化學系退休以後又對日晷生了興趣。很願意將我所知的日晷與你分享。
