# art is science is art

In Silico Flurries: Computing a world of snow. Scientific American. 23 December 2017

# thermodynamics + art

Explore the land of Neradia and meet the snowflake named Arenh Jerrus of Bosmen in the wintertime tale In Silico Flurries: Computing the world of snow,
a Scientific American "SA Visual" story about beauty, imagination and machine learning by Jake Lever and myself.

# It's Snowing in my CPU — a Snowflake catalogue

Art is science in love.

Somewhere in the world, it's snowing. But you don't need to go far—it's always snowing on this page. Explore light flurries, snowflake families and individual flakes. There are many unusual snowflakes and snowflake family 12 and family 46 are very interesting.

## snowflake art posters

These snowflake posters won't melt in your hand, or your wall. Not just for winter, either. They're great for desktops, wrapping paper, or just getting lost.

They're all available for purchase.

## parameter effects

These snowflake posters show what happens to the shape of a specific snowflake when only one parameter is changed.

The $\kappa$ parameter controls freezing. At each growth step $\kappa$ fraction of vapor becomes ice at a boundary site. The remaining $1-\kappa$ fraction becomes quasi-liquid..

The $\rho$ parameter controls the amount of mass in the system. At the start of the simulation, each site is initalized with either $\rho$ ice (snowflake site) or vapor (all other sites)..

The $\mu$ parameter controls melting. At each growth step $\mu$ fraction of quasi-liquid at a boundary site returns to vapor..

The $\alpha$ parameter controls attachment. Boundary sites with 3 snowflake site neighbours attach to the flake if their quasi-liquid mass is greater than $alpha$ and if neighbourhood vapor mass is less than $\theta$..
