More than you ever wanted to know about snow, from the physics of formation to just priddy pictures.

It is snowing outside my window this very moment (Amazon.com PacMed Bldg - Seattle, WA). Flurries! Physics in action! Panic in Seattle!

I thought this was going to be about snow that you see on TV when there's no reception.

I was wondering how you could have priddy pictures of random interference. That'll teach me to read between the lines.

A lovely site. Thanks, Su.

Kokogiak: you lucky bastard! I was 19 the first time I saw snow. Of course I'd read about it and seen it in films but it still took a long time for me to realize what was happening. This was in Manchester, England. I went out and acted like Snoopy, dancing open-mouthed.

It was never the same again, natch. Snow is a first time thing. And it gets uglier the older it gets.

Sweet. I've always wondered how the molecules on each arm manage to coordinate with the others; that is, why do the crystals grow differently between each flake, but almost exactly the same along each arm. And now I know!

From the earliest memories of our childhood, many of us can remember hearing the phrase "no two snowflakes are alike". This discovery was made in the small rural town of Jericho, Vermont by Wilson A. Bentley (1865-1931).

Su: The site still hasn't told me *more* than I ever wanted to know about snow ;)---mostly it keeps peaking my curiosity---but I hope some day these folks will tell me the ALL of what I want to know about snow.

Heads up, everybody: This site asks for your observations. I think they're serious about it if you are.

normy: Thanks for Bentley link. There's stuff here that isn't in the Dover reprint of his book.

WHY??? ---If somebody can write a make-your-own-fractals program, why can't somebody write a make-your-own-snowflakes program? All these pretty little programs floating about the net and there's not a one that will let me crystalize my own virtual snowflake? Somebody's falling down on the job!
