What is the basic shape of snowflakes?

The basic unit is a hexagon, and the heavy snow is a snow mass composed of countless small hexagons, but you can clearly see every small hexagonal snowflake falling on your hand.

Snowflakes are all made up of small ice flowers, each of which has six petals. Some petals release beautiful small lateral tongues like mountain flowers, which are round, arrow-shaped or serrated, some are complete and some are lattice-shaped, but they are not beyond the scope of six petals. The basic shapes of snowflakes are hexagonal and hexagonal prism snow crystals. In nature, it is almost impossible to find two identical snowflakes, just like there are two identical people on the earth.

The scenery is beautiful when it snows, but scientists and artists appreciate the exquisite snowflake patterns. Glaciologists began to describe the shape of snowflakes in detail more than a hundred years ago. Ding Duoer, the originator of western glaciology, described the snowflakes he saw on Loza Peak with vivid and beautiful brushstrokes in his classic glaciology works. These snowflakes ... are all made up of small ice flowers. Each small ice flower has six petals. Some petals release folli's small lateral tongue like Su Hua, some are round, some are arrow-shaped, or serrated, some are complete, and some are lattice-shaped, but they are not beyond the scope of six petals. Tindor's conclusion is correct. All snowflakes are six petals. It was our people who found six petals of snowflakes. As early as BC 100, in the era of Emperor Wendi of the Western Han Dynasty, there was a poet named Han Ying, who wrote A Biography of Chinese Poetry, which clearly pointed out that "there are six snowflakes everywhere." Two years ago, I pointed out that snowflakes are hexagonal, which is really not simple. In Europe, it was not until l6 1 1 that the German astronomer Kepler recorded that snowflakes were hexagonal, which was 1700 years later than China. The basic shape of snowflakes is hexagonal. However, it is strange that two identical snowflakes can hardly be found in nature, just as two identical people can't be found on earth. Many scholars have observed thousands of snowflakes with microscopes. These studies finally show that it is impossible to form snowflakes with the same shape and size and partial symmetry in nature. Among these observed snowflakes, even the regularly symmetrical snowflakes are deformed. Why do snowflakes have the shape of batteries? Because the water vapor content in the atmosphere around snowflakes can't be the same in all directions, as long as there is a slight difference, the side with more water vapor content always grows fast.
