No Two Snowflakes Alike

　　从今年10月份开始，美国邮政总局将发行一套印有雪花图片的邮票，这些图片均是由美国加州理工学院的物理学教授肯尼斯-里布雷希特经过多年野外作业拍摄到的雪花照片。这些精美的照片也揭示了一个事实，那就是世间不会有两朵相同的雪花。

　　Starting in October, the U.S. Postal Service will issue a set of four stamps featuring pictures of snowflakes taken by Kenneth Libbrecht, a professor of physics at the California Institute of Technology. For years, Libbrecht has been studying the physics of snowflakes, looking at the different patterns of crystal growth and snowflake formation. These pictures revealed on thing that is there're no similar Snowflakes in the world.
