Earlier, I posted on Powers of Ten [1]. I’ve long been fascinated by the way numerous relatively similar things can aggregate into macro patterns such as the crisscross that you can see in the photo to the right. 
[2]Naturally occurring pattern like this abound on the beach.
How is it that sand dunes can naturally form out of random sand grains and random wind? Just because it’s difficult to explain doesn’t mean that it doesn’t happen, of course.
The warm-up act of this post consists of three photos I recently took on a beach. First you see the “sand,” then you focus in to see the individual grains of sand. Every one of those grains is different, even though they each look the same from a distance. They are a lot like people in that regard.

The above photos are mere warm up act for this wonderful, mind-stretching display [6] of smallness and largeness. I realize that I featured this display in an earlier post [7], but it is that well done.
