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.

I have been following TED.com (stands for technology, entertainment, and design) for several years now. TED offers hundreds of videotaped talks on every topic imaginable. Click on the science category and you'll find experts and entrepreneurs explaining everything from mathematics to monkey behavior to music. New talks appear weekly. Check it out. It's awesome!! www.ted.com
