Visualized: How Snowflakes are Formed

The Art of Snow

If you look at snow up close, you will probably notice that it is made up of thousands of tiny flakes with beautifully complex designs.

These snowflakes are actually ice crystals. They form in our atmosphere, high in the clouds, and transform along their journey to Earth thanks to different factors and forces.

We look at how snowflakes are formed, and what atmospheric conditions contribute to the beautiful intricacies we’ve come to know them for.

How to Build a Snowflake

The designs of snowflakes are actually products of a crystallization process that is controlled by the atmosphere.

Water vapor in the atmosphere latches onto a free-floating speck of pollen or dust and acts as a nucleator. This means that it can begin to add on (ie. nucleate) more water molecules and grow in size. When this happens at cold temperatures, water also freezes and crystallizes.

Despite the many unique styles of snowflakes, they all crystallize in the exact same shape—a hexagon. The reason for this has to do with how water behaves at the chemical level. At room temperature, water molecules flow randomly around each other, forming and breaking bonds endlessly.

When temperatures cool, however, they begin to lose kinetic energy and form more stable bonds. By 0°C, they reorient themselves into an energetically-efficient position, which happens to be a rigid, hexagonal configuration. This is frozen water, or ice.

All snowflakes nucleate and crystallize this way. As more water molecules nucleate to the infant (Read more...)

Thanksgiving debunked


This post is by Caterina Fake from Caterina.net


I asked my friend who hates Thanksgiving why he hates it and he said because it is a holiday based on gluttony. But every culture has a harvest festival, I said, every culture has feasts. Since time immemorial. Thanksgiving is just the latest version. The problem with it, by my thinking, I continued, is that feasting doesn’t make sense any more. It made sense during times of scarcity and hunger, but in an era of overabundance and overconsumption it seems excessive. Which is not to say we have eliminated hunger, but we live in a strange world where you can be both obese and starving at the same time. For lack of nutrition.

Lots of other holidays that have a less component, candy, mostly, like Halloween and Valentine’s Day. And of course there are birthday cakes. But sugar isn’t a special treat any more. It is something we have too much of and should probably avoid. But to my friend’s objection: I said, That’s just the food part! I said. I like the gathering of friends and family part, and the gratitude.

Here’s a NY Times article that debunks many of the Thanksgiving myths we grew up with in school, its possible origins in genocide or enslavement, and the myth of the Pilgrim. The Pilgrim! I didn’t know this, for example:

It’s been taught that the Pilgrims came because they were seeking religious freedom, but that’s not entirely true, Mr. Loewen said.

The Pilgrims had religious freedom in Holland, (Read more...)
