The Tiny World of Sand

The world at the nanoscale is so interesting. It never ceases to amaze me. I recently came across several TED videos on nano and other small members of our planet. Check out the variety of life in our unseen world. The biological and geological record of life on this planet is all there. It will change the way you think of materials, physics, and even environmentalism. This video shows many components within sand (even sand on the moon). Amazing.
