Snowflakes form in clouds when water vapor in the air condenses directly into ice around some tiny particle, perhaps a speck of dust. The temperature and humidity levels in the cloud are very critical ...

A huge snowstorm could dump more than two feet of snow all over the East Coast, and that means trillions and trillions of tiny snowflakes. Through advances in crystallography, scientists have learned ...

Our understanding of the molecular dynamics of growing crystals is quite primitive, and it is generally not possible to explain why even simple crystals develop their characteristic shapes. A case in ...
