Introduction
It's widely believed that no two snowflakes are alike
— but it turns out that there are various forms of
snowflakes, making the tale a bit more complicated.
But how are snow
flakes formed? Why do snow crystals form with such
symmetry and diversity? How many different types of snow
flakes exists? Can snowflakes be made in a laboratory?
Do snow flakes tell us something about the temperature,
Air pressure or other weather conditions?
