Some people might wonder why I haven't mentioned the weather recently. Really, it's not like nobody else is mentioning it!

Snow is something some of my peers study in great detail. They have little cameras which take photos of individual flakes and have studied how they form. Snow morphology is the name of this field. Ice crystals are essentially hexagonal prisms and, depending on the temperature and humidity, they'll grow short and fat or long and thin, simple or complex. So, if you catch a flake and look at it closely, you can learn about what conditions it has been in.
