Artistic patterns embeded snowy landscapes: a very pretty way to create albedo.

Who would have thought albedo could be so pretty?

“Artist Simon Beck creates amazing pieces of snow art by walking in the snow wearing raquettes (snowshoes). Each artwork is typically the size of three soccer fields and takes 2 days to complete. The Oxford-educated self-employed map maker typically walks for about 5 to 9 hours or until he gets too tired, using a headlamp if it gets dark first.”

Amazing video of the Yosemite Range #whoa

Yesterday, I passed on a link of an epic and breathtaking space video. Now, take a look at how pretty our own planet can be. Best viewed in HD in full screen.

In a word: “Whoa…” Augmented Reality Sandbox

This is seriously amazing. I want boardgames with this feature!

Grain of sand or small moon? Can you guess which is which?

The top image is a portrait of two grains of Coney Island sand. Below it is a NASA image of Phobos, one of the moons of Mars.

Striking graphic showing volume of Earth versus volume of Earth’s water versus volume of Earth’s fresh water

In this illustration, the blue ball represents the volume of all the water on earth, relative to the size of the earth. The tiny speck to the right of the blue ball represents Earth’s fresh water.

Yup. I did a double take too. Here is the wiki entry for this mineral.

Caused by glaciers, earthquake, wind dynamics, pooling rain water, or very very busy gophers?

This mystery might be cool to use in a class about hypotheses generation.

(Click on image for full size).

Specifically: “Mima mounds ( /ˈmaɪmə/) is a term used for low, flattened, circular to oval, domelike, natural mounds found in the northwestern United States, Idaho, Oregon, and Washington, that are composed of loose, unstratified, often gravelly sediment that is an overthickened A Horizon. These mounds range in diameter from 3 to more than 50 m; in height 30 cm to greater than 2 m; and in density from several to greater than 50 mounds per hectare. Within the northwestern United States, they are typically part of what is commonly known as hog-wallow landscape.” (wiki)

See all the hypotheses here. (Admittedly, I’m partial to the thought of busy gophers moving tons and tons of soil!)
